Artificial Intelligence (AI)
Artificial Intelligence (AI) represents systems capable of performing tasks that would otherwise require human intelligence. It utilizes machine learning, deep learning, and natural language processing. AI permeates many industries and is revolutionizing the world around us and our daily lives. This article explores the fundamentals of artificial intelligence, its applications, and incredible potential for the future.
What is Artificial Intelligence
Artificial Intelligence is based on the development of intelligent machines that can perform tasks requiring capabilities similar to human intelligence. These machines are designed to simulate human intelligence, enabling them to perceive, understand, learn, and make decisions.
Types of Artificial Intelligence
Narrow Artificial Intelligence
Narrow Artificial Intelligence (Narrow AI) focuses on performing specific tasks with excellent results. This form of artificial intelligence is specialized and limited to specific areas of activity.
Examples of narrow AI include voice assistants like Siri and Alexa, which can understand and respond to voice commands, including scheduling appointments, playing music, or answering questions. Another example is image recognition systems capable of identifying objects, faces, or characters based on visual data.
These systems are widely used in areas such as security surveillance, medical diagnostics, and autonomous vehicles. Recommendation algorithms used by streaming platforms are also examples of narrow AI. Based on the analysis of user preferences and behavior, these algorithms recommend relevant movies, series, or music based on user history and similarities with other users.
For instance, the AlphaZero algorithm, based on artificial intelligence introduced by Google in 2017, learned to play chess in just 4 hours by playing against itself and constantly improving. It was enough to defeat the previously strongest chess program.
General Artificial Intelligence
General Artificial Intelligence (General AI) aims to achieve intelligence and abilities at the level of human thinking in various areas. It is an ambitious concept seeking to create an artificial system that could exhibit a wide range of cognitive abilities, such as language understanding, learning, creativity, and adaptability.
General AI would enable machines to perform tasks as humans do, adapting to new situations and problems. Achieving general artificial intelligence would revolutionize many areas of human activity, including medicine, science, industry, transportation, and more.
For example, in medicine, general AI could analyze complex health data and suggest the most effective treatment procedures for various diseases. Scientific research could be accelerated and optimized by machines' ability to conduct extensive analyses and search for new discoveries. In the industry, general AI could enable automation and optimization of manufacturing processes, leading to higher efficiency and lower costs.
However, achieving general artificial intelligence remains a significant challenge and remains more of a theoretical goal. Developing such intelligence requires not only advanced algorithms and computational capacities but also an understanding of how the human brain works and its complex cognitive processes. Despite these challenges, general artificial intelligence is a fascinating concept that continues to inspire scientists and developers in their efforts to create intelligent systems.

My blower motor (in the furnace compartment) stopped running the other day, the out side unit runs fine. A service tech found that the high speed wire was loose and reconnected. He also found the motor was running a little hot after a few minutes of operation, said that may have caused the connection to loosen from excessive heat. The next afternoon the motor stopped again, I check connection and it still doesnt run. I pulled the assembly and the motor spins freely and doesnt have any "electrical smell" , it is about 8 years old.
Question, could the run capacitor be the issue and is it likely the motor went bad and still spins freely? Also being in Las Vegas the motor deals with heat from running and an attic that is about 170 degrees , any specific brand of motors that deal with extremes better?

An electrical device that is used to convert alternating current into direct current is called as rectifier. Every embedded system based circuit or project consists of micro-controller as major component. We know that, most of the micro-controllers operate at voltage range of 5V DC.
Especially, 8051 micro-controller that is frequently used for maximum number of embedded systems based applications works at 5V DC. But, in general, the power supply available is 230V AC. So, we need to convert this 230V AC into 5V DC or required DC voltage level. This process of conversion of AC into DC is called as rectification.
The electrical and electronic circuit, which is used for rectification process is called as rectifier. There are different types of rectifiers such as half-wave rectifier, full-wave rectifier and bridge rectifier. The half-wave rectifier converts or rectifies only half cycle of input waveform. The full-wave rectifier converts or rectifies full cycle or entire input waveform. Bridge rectifier also converts or rectifies entire input waveform. But, mostly bridge wave rectifier is used for maximum number of applications as it is more efficient and advantageous than the half-wave rectifier and full-wave rectifier. Every micro-controller based power electronics project requires rectifier, as most of the components need power supply of around 5V DC voltage.
Bridge Wave Rectifier
Bridge rectifier consists of four diodes, which are connected in the form of bridge; hence, these types of rectifiers are termed as bridge-wave rectifiers or bridge rectifiers. Different types of diodes are used for designing bride-wave rectifier. These diodes are classified based on the voltage and current ratings of the diodes. Thus, bridge-wave rectifiers can be classified into different types based on the types of diodes used. Similarly, bridge wave rectifiers designed using diodes are called as uncontrolled rectifiers and rectifiers designed using thyristors are called as controlled rectifiers. Let us start with diodes 1N4007 that are typically used to implement bridge-wave rectifier.
Types of Bridge Wave Rectifiers
There are different types of bridge rectifiers that are classified based on different criteria. Consider different types of bridge rectifiers, which are classified based on the types of rectifiers such as uncontrolled rectifiers and controlled rectifiers. Diodes are called as uncontrolled rectifiers as diodes start conduction whenever the anode voltage is greater than the cathode voltage. But, in case of controlled rectifiers know as thyristors, even though the anode voltage is greater than cathode voltage, thyristors start conduction only when the gate terminal is triggered. Thus, we can trigger the gate terminal as per the requirement; hence, we can control the operation of the rectifier.
Bridge-wave rectifiers that are designed using thyristors are called as controlled bridge wave rectifiers. The operation of the rectification can be controlled by triggering the thyristors gate terminal whenever it is required. We know that the diode is a semiconductor device consisting of two layers (P-N) and thyristor is also a semiconductor device consisting of four layers (P-N-P-N). It can be used as open-circuit switch and also as a rectifier based on how the gate terminal of the thyristor is triggered.
Types of Bridge Rectifier Diodes
There are series of didoes form 1N4001 to 1N4007 with different current and voltage ratings, but frequently 1N4007 is used for designing bridge-wave rectifiers. 1N4007 diode has absolute maximum ratings including voltage rating as 1000V peak repetitive reverse voltage VRPM, 1A average rectified output current IF(AV), 30A non-repetitive peak forward surge current IFSM, which can be operated at -55 degrees to +175 degrees temperature. Thermal characteristics as 3W power dissipation, junction to ambient thermal resistance 50 degrees/W. The didoes that are occasionally used to design rectifiers are series of didoes from 1N5400 to 1N5408 and 6A4.
1N5408 bridge rectifier didoes are also used for some special applications and these are having ratings as maximum repetitive peak reverse voltage 1000V, maximum RMS voltage 700V, maximum DC blocking voltage of 1000V, maximum average forward rectified current 3A, operating junction and storage temperature range -50 to +150 degrees centigrade. ACPWM control for induction motor is a practical example in which a bridge wave rectifier designed using 1N5408 diodes.
These 6A4 bridge rectifier diodes have maximum ratings and electrical characteristics as maximum recurrent peak reverse voltage of 400V, maximum reverse voltage of 280V, maximum DC breaking voltage of 400V and maximum average forward rectified current of 6A. 6A4 diodes are used for bridge rectifiers in some special applications, an example is propeller display of message by virtual LEDs. Working of bridge rectifier circuit is similar irrespective of the diodes used to design rectifier, so let us consider the bridge wave rectifier circuit designed using diodes 1N4007, as it is used for bridge rectifiers in some special applicatins – for example a propeller display of message by virtual LEDs.
Working of the Bridge Rectifier Used to Convert 230V AC to 5V DC
Step-down transformers are used to convert 230V AC (high voltage) into 12V AC (low voltage). This 12V output is an RMS value and its peak value is given by the product of square root of two with RMS value of the output of step-down transformer, which is approximately 17V. The working principle of transformers is based on Faraday’s laws of electromagnetic induction.
Uncontrolled Bridge Wave Rectifiers
230V AC power is converted into RMS value of 12V AC or peak value of 17V (approx.), but 5V DC is the required power; for this purpose, 17V AC (peak value) power is converted into DC power, then it is stepped down to 5V DC. The 17V AC is converted into DC using a bridge-wave rectifier that consists of four diodes, which are called as uncontrolled rectifiers. Diode will conduct only in forward bias and will not conduct during the reverse bias. If anode voltage of diode is greater than cathode, then the diode is said to be in forward bias. Diodes D2 and D4 conducts during positive half cycle and diodes D1 and D3 conduct during negative half cycle.
This charging and discharging of the capacitor make the pulsating DC into pure DC, as shown in figure. A step-down converter namely IC 7805 voltage regulator is used to convert 15V DC to 5V DC.
Block diagram of IC7805 voltage regulator is shown in the above figure. It consists of an operating amplifier that acts as error amplifier, zener diode used for providing voltage reference.
In general, 7.2V to 35V is the operating voltage range of IC7805 regulator. If the input voltage is 7.2V, then it gives maximum efficiency and, as the voltage exceeds 7.2V efficiency will decrease as there will be loss of energy in the form of heat. So, heat sinks are used to protect the regulator from over heat. Even without using transformer, we can directly convert 230V AC into 5V DC using high-rating diodes. If we have 230V DC power supply, then we can directly convert the 230V DC into 5V DC using a DC-DC buck converter. Feel free to post your comments in the comment section below and encourage other readers to learn the basics about rectifiers.

experimental video work
This experimental video is an exploration and realization of human dependency on modern technology and marks how technology has changed behaviors. Technology has become an integral part of human life and we cannot envision our daily lives without the use of technology. Even the older generations rack their brains to figure out its use and integration into their lives.
As I observed my father, struggling to hold his mobile phone in his shaky hands, switching between videos and social media messages, I found myself constantly questioning why the noise of technology is so normalized into our lives? Perhaps we need that noise, that chaos, to escape the silences and loneliness inside us.

This is a breakout PCB for the MAX17043 single cell Li-Poly/Li-Ion fuel gauge. Determining the state of charge for a Li-Poly battery can be very difficult to determine due to the relatively flat discharge profile. Using a 2-Wire (I2C) interface, you can get the relative state of charge(SOC) displayed as a percentage. The board can also generate an external interrupt to alert the user if the battery charge falls below a "programmable" value of 1 - 32%. This is a useful feature if you don't want to have to continually poll the battery, just program an interrupt routine for low battery.
The board features 2 JST connectors for connecting the battery. The battery can be plugged into either connector. The second connector can be used as a bypass to the rest of circuit if you are placing the board in-line to an existing design. Since the board is powered by the battery the VDD pin must remain floating. It is possible to power the board from a 3.3/5 volt supply instead of using the battery but you will need to remove the solder from SJ1 first and then connect an external supply to VDD. There is no value added in doing this but the option is available if need be. Also please be sure to connect the battery using the correct polarity as there is no reverse voltage protection built in which means you could damage the IC and also battery.
The board is not affected by an external charging circuit, as a matter of fact you can monitor the battery SOC while it is charging to help determine how long until a full charge is reached.
NOTE ABOUT SOC READING AT FULL CHARGE
A couple of people had requested I look into the calibration procedure as described in the datasheet because they were getting SOC readings around 1-2% above or below the 100% level at full charge. Unfortunately Maxim was reluctant to provide details on how the configuration register can be adjusted. I decided to try different settings in the configuration register to come up with a calibration routine but was unable to produce significant enough variations in the final SOC reading to make an impact. After more testing I found that the charging circuit that is used seems to play the biggest role on the final SOC reading. I tested two different charging circuits and was able to charge the same battery to only 98% on one and a little over 101% on another.

Recent advances in next-generation sequencing technology have significantly promoted high-throughput experimental probing of RNA secondary structures.
The resulting enzymatic or chemical probing information is then incorporated into a minimum free energy folding algorithm to predict more accurate RNA secondary structures.
A drawback of this approach is that it does not consider the presence of alternative RNA structures.
In addition, the alternative RNA structures may contaminate experimental probing information of each other and direct the minimum free energy folding to a wrong direction.
In this article, we present a combinatorial solution for this problem, where two alternative structures can be folded simultaneously given the experimental probing information regarding the mixture of these two alternative structures.
We have tested our algorithm with artificially generated mixture probing data on adenine riboswitch and TPP riboswitch.
The experimental results show that our algorithm can successfully recover the ON and OFF structures of these riboswitches.

As data centers continue to proliferate worldwide, their energy efficiency has swiftly emerged as a pressing concern. These centers are indispensable to modern life, storing and processing vast amounts of data that drive everything from online banking to social media. Yet, these centers are also significant power consumers, often guzzling more energy than entire cities. Given the urgent need to reduce global energy consumption, the question arises: how can we optimize the energy efficiency of data centers?
One promising solution lies in artificial intelligence (AI). Cutting-edge AI technologies, particularly machine learning algorithms, are playing an increasingly critical role in improving energy management in data centers. These tools offer major potential for reducing energy consumption, enhancing operations, and paving the way for a more sustainable future.
Artificial intelligence is a game-changer for energy efficiency in data centers. Its ability to analyze vast datasets and generate actionable insights can be instrumental in reducing power usage.
Machine learning algorithms, a key AI technology, can predict and manage data center energy consumption with astonishing accuracy. These algorithms learn from historical data, identifying patterns and correlations that might otherwise go unnoticed. With this information, they can forecast future energy demands and adjust power usage accordingly, ensuring that no energy is wasted.
AI also enhances the realism of data center simulations, allowing operators to experiment with different settings and configurations in a safe, controlled environment. This can help to pinpoint the most energy-efficient setup for a data center and avoid costly trial-and-error in the real world.
Cooling is one of the most energy-intensive aspects of data center operations. Traditional cooling methods often consume vast amounts of energy, and it’s not always possible to predict how much cooling a data center will need at any given time.
Enter AI. Machine learning algorithms can predict cooling needs based on numerous factors, such as the amount of data being processed, the time of day, and the ambient temperature. Furthermore, AI can control cooling systems in real-time, adjusting their operation to match the current needs of the data center.
This results in a dynamic, responsive cooling system that minimizes energy waste. It also reduces the risk of overheating, a major cause of data center downtime.
AI’s abilities extend beyond energy management and cooling. It also plays a crucial role in the wider management and security of data centers.
Machine learning algorithms can predict and prevent many common causes of data center downtime, such as hardware failures and power outages. By learning from past incidents, these algorithms can anticipate future issues and trigger preventative measures, thus reducing downtime and improving the reliability of data center services.
Furthermore, AI-powered systems can detect and respond to security threats faster than humans ever could. In a world where data breaches are increasingly common and costly, this ability is invaluable. AI systems can flag suspicious behavior, shut down potential attacks, and even repair damage caused by successful breaches, all in real-time.
Looking to the future, AI technologies will continue to refine and optimize data center operations, with a key focus on energy consumption.
As machine learning algorithms grow more sophisticated, they will become increasingly proficient at predicting and managing energy usage. They will also become better at detecting inefficiencies and recommending improvements, further reducing energy consumption and carbon emissions.
AI-powered automation will also play a larger role, taking over more of the routine tasks involved in data center management. This will free up data center staff to focus on more strategic, high-level tasks, such as planning for growth and innovation.
Finally, AI will enable more effective remote management of data centers. With AI tools, operators will be able to oversee and control their data center operations from anywhere in the world, reducing the need for onsite staff and further improving efficiency.
The optimization of data center energy consumption is a complex problem, but one that AI is uniquely equipped to tackle. By harnessing the power of machine learning and other AI technologies, we can make data centers more energy-efficient, more reliable, and more secure, supporting a more sustainable future for all.
Renewable energy has become an increasingly popular solution to reduce the carbon footprint of data centers. When paired with artificial intelligence, this solution becomes all the more powerful.
AI can optimize the usage of renewable energy sources in data centers, ensuring that energy is consumed in the most efficient manner possible. Machine learning algorithms use predictive analytics to forecast both energy supply from renewable sources and demand in the data center. By analyzing these forecasts, AI can optimize when and how renewable energy is used, ensuring that it is utilized when it is most abundant and cost-effective.
This approach not only improves energy efficiency but also reduces reliance on non-renewable energy sources. This is a key step towards creating green data centers that are not only efficient but also environmentally friendly.
AI also has a critical role in predictive maintenance of renewable energy systems in data centers. By analyzing data from these systems in real time, AI can identify potential issues before they become severe, allowing for timely maintenance that prevents costly downtime.
Artificial intelligence is reshaping the landscape of data center operations. It offers countless benefits, from boosting energy efficiency to enhancing security. As we move towards a future where data is more integral to our lives than ever before, optimizing data center energy consumption is crucial.
AI is an indispensable tool in achieving this goal. Its ability to predict energy usage, control cooling systems in real time, and optimize the use of renewable energy is revolutionizing the way we manage data centers. It’s not just about improving energy management—it’s about creating a more sustainable, efficient future for data centers.
The potential of AI in data center operations is vast and we are only scratching the surface. With advancements in machine learning and predictive analytics, we can expect more innovative ways to optimize energy efficiency in data centers.
As the technology continues to evolve, AI will play an increasingly important role in reducing the carbon footprint of data centers and making them more energy efficient. In the process, it will also help to mitigate the impact of data centers on the environment, supporting a more sustainable future for all.
In conclusion, AI holds the key to the future of data center operations. By harnessing the power of AI, we can not only make data centers more energy efficient but also pave the way for greener, more sustainable data centers that are built for the demands of the future.

Chris Pfende, CEO of Niantic Labs, and the man behind the popular Pokemon Go mobile game has some interesting comments to make about the future of mobile gaming. In an interview with GamesTMrp, Pfende says that mobile gaming is going to see a lot more innovations in the next few years. One of the new innovations he speaks about involves the possibility of hand-held devices that will allow users to interact with the characters in the game. Right now you have the ability to do this with just a tap of the screen but according to Pfende there will be further developments. "You are looking at something like a digital camera or smart phone that will allow the player to interact with the characters in the game," he said. The way this works is that you can take pictures of your favourite Pokemon characters to use as stickers or other in-game applications.
In the future we may see augmented reality, which will allow gamers to virtually interact with items in the real world, especially with Pokemon characters. This is a relatively new technology and according to Chris Pfende it represents a 90 million opportunity for mobile gaming platforms. He states, "augmented reality is just another step in the ongoing evolution of mobile gaming and another opportunity for us to put the power of gaming into the hands of the consumer."
Another innovative idea comes from the likes of Pokemon Go, which now allows mobile gamers to take on the role of their favourite Pokemon characters in the game. Users can travel around the world and catch Pokemon, where they can then interact with other players and other Pokemon creatures. The fascinating aspect of this mobile gaming platform is that gamers are able to catch Pokemon at locations that coincide with where they have gone before. This will enable gamers to return to previously visited areas in the game, which will allow them to experience a sense of repetition in the process. To understand more about the mobile gaming platform, click here: http://cz.gamemine.com/static/help.
Industry analysts have predicted that mobile games will continue to expand at an exponential rate, with more new IPs being announced each week. With smartphones capable of supporting high quality graphics, the increase in the number of people that own smart phones is also expected to lead to an increase in mobile games. It is therefore no surprise that Smith said that the mobile gaming platform market is "on its way" to capturing the entire mobile games market. View here for more details about the mobile gaming platform.
Smith also touched upon another topic that concerns the high spenders within the market. Mobile gaming devices such as smart phones, tablets and Nintendo Wii can only be used for so many hours per day before the user would become bored and want to switch devices. However, Smith believes that with the high demand for mobile devices, it will be very difficult for companies not to provide a good solution. "You will be seeing a lot of companies coming out with applications that will enable you to play a couple of games and then go back to your social media or your email for a couple of hours and then do it all over again", he said.
However, he declined to provide specific details about the applications that will be launched in the near future. So how will consumers be able to keep up-to-date with what games they can download?
According to Smith, the answer lies in the company's plans to launch a mobile development studio. The studio will house around 15 programmers that will work on creating different apps for the iOS platform. Smith said that once the studio has been set up, the company will start to focus on focusing on apps that can be used by teenagers and children as well as adults. A full shutdown of the iOS app store is unlikely at this point, with the aim of making the platform more appealing to a mainstream audience and to regain lost market share that the iPhone and iPad have gained in recent years.

Updating U-Boot and SPL on the StarFive VisionFive 2
Embracing the Future with RISC-V Architecture
Ubuntu's recent foray into providing developer preview images for the emerging RISC-V architecture marks an exciting development for RISC-V enthusiasts. This is particularly true for those experimenting with popular supported development boards such as the StarFive VisionFive 2.
The prospect of running Ubuntu, or the latest Debian versions provided directly by StarFive, hinges critically on having the latest U-Boot and SPL firmware on these boards. However, working through the update process can be a challenge due to fragmented and sometimes confusing documentation.
So, if you are excited about running the latest operating systems on your VisionFive 2 board, then you are in the right place! In this post, I aim to demystify this process, offering a guide on updating your board's firmware through the most reliable methods, whether you're a seasoned tinkerer or a curious hobbyist exploring the potential of RISC-V architecture.
🔍 A Primer on U-Boot and SPL
Feel free to skip over this section if you are just here to update the firmware!
Before diving into the firmware update process, let's take a look at what U-Boot and SPL are and their roles in the VisionFive 2 board.
In the context of the VisionFive 2 board, U-Boot acts as the universal bootloader, a critical piece of software that orchestrates the booting process. It initialises the board's hardware, such as CPU and memory, and sets up the necessary environment for the OS to run. U-Boot is highly versatile, allowing for a variety of boot mediums and providing a rich set of commands for configuration and diagnostics via a serial console, making it an essential tool for developers.
Complementing U-Boot is the Secondary Program Loader (SPL), which is the minimalistic first-stage bootloader that takes action immediately after the board is powered on. The SPL's role is to perform the fundamental hardware initialisations and to prepare the system so that the more comprehensive U-Boot can take over the process.
This two-stage boot process ensures that the VisionFive 2 can handle the complex boot scenarios required by modern computing environments while maintaining the flexibility and robustness needed for the development and deployment of various applications on this RISC-V platform.
🤔 Which Method Should We Use?
We will use the SD Card image method to update the board. While there are other methods to update the firmware, the SD Card image method is preferred due to its reliability and simplicity.
In most cases, if you have not updated the board's firmware, then the latest version of StarFive's Debian release, nor Ubuntu, will even boot in the first place.
You should also use this method if you are trying to use the
flashcp command method and hit the
u-boot-spl.bin.normal.out won’t fit into /dev/mtd0! error message.
Hardware you will need:
A MicroSD card (any size 1GB or more should work)
A USB flash drive
USB to UART dongle (optional, but required if you want to run Ubuntu later)
Grab the latest version of the following files from the VisionFive2 Firmware Repo:
u-boot-spl.bin.normal.out- put this on the USB flash drive
visionfive2_fw_payload.img- put this on the USB flash drive
sdcard.img- flash this to the MicroSD card using Etcher
⚒ Hardware Setup
Set the DIP switches to set the Boot Mode to SDIO
Install the MicroSD card you flashed earlier, plug the USB drive into any of the USB ports and ensure you have either an Ethernet network connection (for SSH) or HDMI and keyboard and mouse available.
Optionally, if you intend to use Ubuntu later, then you will need to set up the USB to UART device using the GPIO pins. I am using the rather handy Raspberry Pi Debug Probe for this. The leads need to be connected from the board to your UART cable as follows:
Pin 6 ->
Pin 8 ->
Pin 10 ->
🔄 Updating U-Boot and SPL
Power on the board and let it run through the boot process fully. This can take some time, but just let it run until you get a prompt. To run the commands following commands, you can either enter them directly or use SSH.
If you hit the dreaded
mipi_0p9: disabling hang during the boot, you will need to SSH into the board as it is likely you are using a 4K monitor, which has been known to cause some issues. The username and password you need are
Next, we need to mount the USB drive so we can access the files. This is required as the image we are using right now is so minimal that it does not include any tools that will let us download the files or even a way to install them.
List the available disks with the
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS
sda 8:0 1 116G 0 disk
|-sda1 8:1 1 200M 0 part
`-sda2 8:2 1 115.8G 0 part
In this case, sda2 is the drive and partition we need. Now we can mount the drive and access the files with:
mount /dev/sda2 usb
Next, we need to list the MTD devices so we can be sure we are flashing the correct firmware to the correct device:
# cat /proc/mtd
dev: size erasesize name
mtd0: 00040000 00001000 "spl"
mtd1: 00010000 00001000 "uboot-env"
mtd2: 00300000 00001000 "uboot"
mtd3: 00100000 00001000 "data"
In this case, we need to flash the SPL firmware to
mtd0 and the U-Boot firmware to
mtd2. This is done using the
flashcp command and providing the files from the USB drive:
⚠ Ensure you choose the correct device! ⚠
flashcp -v u-boot-spl.bin.normal.out /dev/mtd0
flashcp -v visionfive2_fw_payload.img /dev/mtd2
You should see output along the following lines if successful:
# cd usb
# flashcp -v u-boot-spl.bin.normal.out /dev/mtd0
Erasing blocks: 36/36 (100%)
Writing data: 143k/143k (100%)
Verifying data: 143k/143k (100%)
# flashcp -v visionfive2_fw_payload.img /dev/mtd2
Erasing blocks: 736/736 (100%)
Writing data: 2943k/2943k (100%)
Verifying data: 2943k/2943k (100%)
Now shut down the board and you are done updating the firmware!
👷 Preparing for Ubuntu
If you want to run Ubuntu, there is an extra step and this is where the USB to UART bridge is required. After flashing the latest firmware, we need to reset the U-Boot environment variables to default values, otherwise, the installer/image will not boot.
To access the U-Boot console, you can use
picocom. On macOS this can be installed with
brew install picocom.
Next, find the USB to UART bridge device and connect to it. On macOS for example, these devices usually appear as
tty.usbmodem devices, so look for it with the following command:
ls /dev | grep tty.usb
Then connect to it:
sudo picocom -b 115200 /dev/tty.usbmodem2112402
You should be greeted with
Terminal ready if this was successful.
Next, power on the VisionFive 2 board. You will see a large amount of output, but for a few seconds you will have the chance to interrupt the boot process to allow us to drop into the U-Boot console:
Hit any key to stop autoboot: 2
Now you need to run the following commands:
env default -f -a
The output should look like this:
StarFive # env default -f -a
## Resetting to default environment
StarFive # env save
Saving Environment to SPIFlash...
Erasing SPI flash...
Writing to SPI flash...
Shut down the board again and now you are prepared to run Ubuntu on your StarFive VisionFive 2 board! 🎉
📌 Round Up
Now your StarFive VisionFive 2 board is fully updated and ready to run the latest operating systems! While the process is not very obvious from the official documentation, it is overall fairly simple once you get the hang of it. So, next time you need to update your board, simply follow the same steps as before and you will be up and running in no time.
For the next steps on running Ubuntu, visit the Ubuntu Documentation to find out the different options for getting going with Ubuntu on this board.


I am also a bit concerned about second harmonic distortion and wonder if some added circuitry (& admittedly added complexity) can neutralize more of it through inherent structure. Earlier Class A designs published by Pass like the A75 have more traditional topologies. But even a Class A push-pull output stage gets away from the elegant minimalism of Pass' Zen musings, and does add more stuff in the signal path. By way of overview, Zen are single stage, early Pass Aleph commercial amps are 3 stage, 2 in later Alephs, and 2 stages with inverting and non-inverting, positive and negative (4 way) output stage symmetry in the X amps. Alephs are single ended outputs, and X are sort of quad single ended. After reviewing two decades of Pass' designs, I'm leaning towards the A75 for some of the reasons described below. A75 is 2 to 2.5 stages, balanced, all class A, with push-pull outputs. A75 is fairly conventional, but has lower distortion and is still quite simple.
Class A amps need to dissipate a lot of heat and one of the biggest problems the Do-It-Yourself hobbyist amp builder faces is finding sources for chassis and especially the big heat sinks needed. John Inlow provides plans for an amp chassis with heat sinks made from aluminum bar stock for a truly DIY solution. At 0.55 degree C/W, this heat sinking is only suitable for smaller amps, so I'd probably use multiple 6 inch lengths of commercial Themalloy or Wakefield extrusions bolted to a chassis of Aluminum plate and bar. See also his link to SM0VPO's brief heat sink tutorial.
Chronologically, the original Zen design was a single MOSFET, and Son of Zen was a differential pair of power MOSFETs. While the original Zen had a constant current source, Son of Zen had simple resistors supplying the bias current. Zen was capacitively coupled on the input and output, and Son of Zen was DC coupled. Zen used modest feedback while Son of Zen used none.
Active current sources offer about four times the efficiency of passive resistors, and they also improve the rejection of power supply noise and fluctuations. They do however add another transistor into the circuit, which was objectionable to some minimalist-inspired readers. A differential input means balanced signals can be used to drive the amp, which makes for potentially cleaner signal transmission due to common mode noise rejection. Getting rid of the capacitors on input and output is a good thing since only horrible sounding electrolytics could be used in the large values required.
Hoffmann's design is at the same time a good reading of Pass' work and a classic, simple op amp with some feedback. It uses a differential input pair and a follower (two gain stages) with each stage biased by a constant current source. He also runs split power supplies so the inputs and outputs are direct coupled. Power output with 25 VDC rails is 35 watts into 8 ohms, half that into 4. Like most of Pass' recent commercial designs, it's a big, simple power opamp using International Rectifier HexFET Hybrid MOSFETS. I plan to build a pair, probably with higher-voltage, regulated supplies on each stage.
So I'm now thinking of starting with a Pass/Thagard A75, adding beefier and regulated power supplies, some audiophile type passive components such as Vishay bulk foil resistors and Rubycon Black Gate capacitors in most locations. Since the design is fairly minimalistic there aren't too many non-key locations to use "regular" Dale/Vishay RN55D resistors, Panasonic HFQ electrolytics, etc. though parts of the circuit that don't handle the signal directly or don't vary much might qualify. Another source of improvement could be lower noise precision voltage references to replace the zeners.
Like Zen and Aleph, the A75 is all Class A, but A75 has a balanced input and push-pull output. It also has a lot more power (150 watts and above into 4 Ohms). Being push pull, it's around 45% efficient versus 20% for single ended. Push pull also means the dominant second harmonic produced by all transistors' non-linearities is largely canceled out due to the complementary output. Yes this could make third and other odd order harmonics more noticeable, but with good matching and tweakable feedback levels, the objective distortion levels are well down and much lower than Pass single-ended designs.
Unlike Zen, A75 has what looks like a folded cascode driver stage, which would normally be thought of as the middle stage of a three stage design. But the folded cascode is arranged so that half of it acts as a current source and the gain and drive actually comes from the differential input transistors. In his introduction Dr. Thagard thus describes the design as having a compound single input stage, effectively resulting in a two stage amp. The design includes the option to run as essentially three stage by increasing the contributions of the folded cascode, resulting in more loop gain and greater negative feedback levels and lower distortion. Tuning out the folded cascode results in a simpler gain path and different sound. I would probably build A75 as designed, but with top quality parts. Would also build them as monoblocks with much larger toroidal transformers (say 1 kW Plitrons) and possibly higher supply voltages for more power. Only the filter caps would really care about higher voltage up to about +/- 100 Vdc. It would probably also be good to regulate the output stage power supply. The downside of more voltage and more bias is more power consumed and heat produced, meaning more waste and more heat sinking needed.
Here is a table comparing various Pass-related DIY Amplifier designs. I was finding it challenging to remember the variations so I though I would make this comparison chart to help sort them out.
Judging by the service manual schematic, the Adcom GFA-5802 looks like a dumbed-down relative to the A75. It's certainly based on a Pass design, with very similar ideas and even some identical component values. However the GFA-5802 is capacitor-coupled at the inputs, and it lacks some of the more sophisticated circuitry of the A75. They may share some sonic attributes but the A75 is very likely superior.
Nelson Pass responds to questions from DIYs and buyers in a guest forum at AV Science. There he describes differences in his commercial amps, offers some advice to DIY amp builders, and also clarifies his relationship with Adcom as: “Adcom has licensed the basic circuits employed in most of their amps and preamps, but I am not involved in construction and parts selection and so on.” Pass also contributes an occasional response at the DIYaudio.com forum where seeming legions of fans embrace his designs.
Wow! Found an excellent article on heatsinks at Rod Elliot's sound site. If the rest of the articles are as good, they are a huge contribution to on-line audio knowledge. MMM Metals appears to be a major manufactuerer of extruded, bonded, etc., heatsinks.
It is also possible to perform the modulation entirely in the digital domain. How about an amplifier that takes the digital signal in PCM from a CD or DVD and, without first entering the analog domain through a D/A converter, modulates it directly from PCM into PWM?
In essence the amplifer becomes the digital-to-analog converter. Attenuation should be done in the digital domain, not on the PCM side, but on the PWM side. (In other words, to attenuate the signal (i.e. turn down the volume) don't throw away bits on the PCM input, instead narrow the PWM pulse widths on the output.) This topology would eliminate a lot of analog problems, though of course it raises other challenges, such as proper filtering and feedback. Naturally the attenuation algorithm would be another key. It also creates a significant burden on jitter and clock cleanliness within the modulator if the results are to be good. I also suspect the PWM analog post-filter should deserve a close look. As we have seen in DACs, analog filtering is crucial and can not be a casual afterthought. Again, problems (challenges) get shifted into other areas. It would be interesting to experiment with this approach. It should have some good potential. Perhaps there are already some commercial examples? If not, perhaps there should be.
Such purely digital amplifiers already exist in sound reinforcement and very low-end consumer electronics, and one or two of high-end examples have been tried.
Some interesting Class-D documents:


Valentine Research (www.valentineone.com)
One of the better radar/laser detector on the market. (Of course, we don't use ours in Virginia.) The Valentine One uses front and rear antennas reporting to an on-board computer to analyze and precisely locate every radar threat, either by direct reception from one antenna or triangulation between both antennas. It will tell you if the radar/laser is in front, beside or behind you. It will also tell you how many radar/lasers are targeting you.


Bitcoin “Taproot” soft fork
The Taproot update proposal was released in January 2018 by Bitcoin Core developer Greg Maxwell, in 2021, the 90% threshold of blocks mined with a support signal from miners was met.
The privacy implications of Taproot soft fork are the most important part of the upgrade. By introducing Schnorr signatures and key aggregation, multisignature contracts no longer look different from single signature contracts, providing privacy to all Taproot users.
In the next seven days (aprox November 14th 2021), the Bitcoin protocol will start a soft core upgrade that is composed of three Bitcoin Improvement Proposals (BIPs) which define three distinct upgrades to the Bitcoin protocol:
Schnorr Signatures — Schnorr signature technology implements a smaller, more secure and flexible type of cryptographic signature. It also introduces a technique called “key aggregation,” which enables multi-signature transactions and smart contracts to commit the same amount of data to the Bitcoin blockchain as a standard, single signature transaction.
With Schnorr signatures, multisig transactions can be combined into one key, making them indistinguishable from regular monosig transactions. These smaller and faster transactions using the Schnorr signature will also free up space and bandwidth on the Bitcoin network. If 100 different users sent BTC to a single wallet address under the current setup, it would appear on Bitcoin’s as 100 separate transactions. With the next upgrade, Bitcoin’s network will be able to bundle these 100 transactions into one transaction with a unique key.
Taproot — defines how Bitcoin’s protocol will integrate Schnorr signatures. Bitcoin Script must be updated to also evaluate Schnorr signatures. Taproot also integrates Merkelized Alternative Script Trees (MAST), which allow users to lock outputs to multiple scripts.
Tapscript — defines how Bitcoin’s protocol will integrate Schnorr signatures. Bitcoin Script must be updated to also evaluate Schnorr signatures. Taproot also integrates Merkelized Alternative Script Trees (MAST), which allow users to lock outputs to multiple scripts.
Miners in the Bitcoin network have until November to update their software to Bitcoin Core 0.21.1, the newest version of Bitcoin Core that contains the latest improvements.
