ACRIS is an end-to-end system that provides the capability to control individually addressable RGB LED light fixtures.
The ACRIS project includes:
The principle board, ledctrlr, can drive up to 5 RGB LEDs and communicates to the host via an RS-485 network.
The project also includes boards for other purposes, such as providing a USB serial interface to an RS-485 network.
The ledctrlr board aims to be compact yet versatile. In one embodiment, it was installed into an inexpensive consumer wall sconce purchased at a hardware store. The existing incandescent fixture was removed, the board was installed into the back of the unit, and RGB LEDs were mounted onto a simple piece of sheet metal. The sconce’s diffuser provides a pleasant smoothing of the resulting light output.
Other fixtures can easily be prototyped, such as a retrofitting of an IKEA light:
Or even a sanded-and-etched piece of acrylic:
ACRIS uses the Atmel AVR microcontroller in its boards. Each board is individually addressable; its address can be set when in bootloader mode, whereby it is stored to EEPROM.
The bootloader provides functionality for a host to set board address and to write a new application to application memory. The bootloader software can perform operations on some or all devices within the network.
The main application listens for lighting control packets sent to the device’s address and controls the LED drivers accordingly. A simple protocol allows for both 8- and 12-bit resolution of the desired values.
ACRIS’s software tools (written in Python) aim to provide a high-level interface for interaction with any network of light fixtures.
A simple Python script provides functionality for addressing and programming boards.
An extensible framework provides facility for introducing new light fixture types and interacting with them. Display patterns for light fixtures can be assembled into environmental plugins, which are in turn controllable from a server-client architecture. Multiple plugins can be active (so long as they do not address the same light instrument), allowing for a high degree of environmental configurability.
The server is responsible for continuous playback to the light fixtures and can be controlled via a simple socket connection from a client.
The NRF24L01+ wireless chip can be used to establish a simple wireless network of ACRIS boards. Current top-of-tree focuses on shifting from RS-485 to this wireless technology.
Shift to an ARM-based MCU with more resources would enable transition to other wireless network architectures.


By @Wicho – May 26, 2021 The PiDP-11 – Oscar Vermeulen The PiDP-11, developed by Oscar Vermeulen, recreates a 1975 PDP-11/ 70 at 6:10 scale. Well, it recreates the console from which it was switched on and off and you could do program debugging by examining memory places using an entire collection of bulbs and switches. And is that the cabinet which contained the original CPU determined 181.3 centimeters high by 108 high and 76 deep. In addition to weighing 227 kilos. Why the 11/70? Well, precisely since that console in plum colors and complete of switches and lights is thought about to be the style culmination of the range. And in general of microcomputers. It wouldn'' t be out of location on the Enterprise. It is moved by a Raspberry Pi with the simH emulator and the necessary software application not only to reveal the memory status of the emulated PDP-11/ 70 on the console, but likewise to check out the position of the switches so that they act on the emulation. In addition, you can link a VT-220 or similar terminal to make things even more sensible. If you don'' t have one of those terminals, you can link it to a computer and utilize its screen as a display for the PiDP-11. A vt220 and the pidp-11 – Oscar Vermeulen It costs 245 euros plus shipping, although there is a waiting list since Oscar just offers his life to produce a couple of kits every month. Compared to the $ 20,000 it originally cost, inflation aside, it'' s a deal. Of course, the Raspberry, its power supply and its sd card are not included in the cost. It is an intriguing project for computer system geeks, particularly retrocomputers, although it is not of a standard level; you have to solder a great deal of elements to make everything work, plus the Raspberry Pi software application. Beige-O-Vision has a series of 4 videos– in English– covering the entire procedure: PiDP11 Kit Build – Part 1, 2, 3 and 4. But in any case … who said worry? And when you'' re done, Oscar likewise has the PiDP-8/ I and the Kim Uno, which play the PDP-8/ I (surprise!) And KIM-1 respectively. Why the PDP-11? Due to the fact that it is among those things that a lot of us who have been tinkering with computer systems for a long time have actually burned into our memory. The PDP-11 from Digital (officially Digital Equipment Corporation, DEC) is a design of computer – or rather a family of computers – mythical. It was the very first and only 16-bit computer system produced by the company. It remained in production from the 1970s to the 1990s. They can running Unix – in fact the very first version of Unix with that name ran on the 1970 PDP-11/ 20. They supported several users and several procedures, and all this at a microcomputer price when mainframes still ruled the Earth. In reality, there are those who state that it is the most popular minicomputer in history. In Bitsavers there is a manual of the PDP-11/ 70 in PDF in case you wish to gossip about it.

IT companies are a major backbone of the global market in the current times. They not only drive digital transformation for businesses but also help in building technologies that create customer-centric experiences for brands. However, despite the stringent measures, the IT companies too have not been untouched by the rising cyberattacks. There has been a substantial rise in the number of data breaches on IT companies. Although the companies deploy some of the latest technologies and techniques to secure their database even further, the same technology is being used by hackers to find workarounds. However, data encryption has been one of the major tools that can help IT companies safeguard their data. The data used by these companies is very critical, and when in the wrong hands can cause severe consequences for the brand.
Data Attacks on the IT companies
Cyberattacks on IT companies have increased in the last couple of years. It has been one of the major segments where hackers have been actively trying to steal major chunks of data. In the past, there have been many such incidents, where major IT firms were attacked by hackers and experienced data loss their servers.
One of the biggest players in the IT sector, Microsoft, was attacked by a cyber hacking group Lapsus$, which was based out of South America. The hacking group used a wide variety of tactics to do so. They were able to steal personnel information and gain access to the sensitive information. The same technique was also used to access and control source code for the products. Similar attacks were done by the same group on Okta, NVIDIA, and Samsung.
When NVIDIA was attacked, more than 71,000 employees were affected as their credentials were stolen. Also, the source code of Nvidia’s DLSS (Deep Learning Super Sampling) AI rendering technology and information was stolen, which was still pending announcement.
Okta faced similar issues where the same hacking group was able to hack the customer data of Okta. The hack was done through the laptop of an employee that was hired by the contractor. The data breach lasted 25 minutes, during which two companies authentication systems had been accessed.
Data Attacked at the IT Companies
IT companies work on various kinds of data and products. Some of the few examples are digital products, security software and other important source codes that could shape the future of technology in the world. Now imagine a group of hackers was able to hack into the data and find a backdoor into the software or technology without anyone knowing. The risk turns even larger when the technology is related to financial institutions.
The data that the IT companies hold is extremely critical and hackers try regularly to hack into their databases and get access to as much data as possible. In the past, hackers have been able to release the details of many such programs and technologies which were not even launched in the market. Due to this, the companies had to suffer a great deal of loss in terms of both financial and reputation. Hence, data encryption is one of the major requirements for IT companies, to ensure that their data cannot be interpreted by hackers.
Need for Encryption at the IT Companies
Data encryption software protects the data stored on the laptops, computers, removable drive and even before uploading on the cloud. This enables IT companies to secure any kind of data related to the technology they are developing, and the source codes associated with it. The software also ensures that the hackers are devoid of any access to the novel products or technologies that are being worked upon by the IT companies.
New technologies which are yet to be patented are developed to be more secure and efficient. If hackers get their hands on it, the technology can be misused. Overall, the hackers will be able to hold the company for ransom through ransomware and can also leak the data on the dark web.
Without data encryption, there exists a chance that can get the data hacked, which could cause some serious issues for any IT company. An IT company which has a data leak can loses its reputation in the market as well trust of its clients’. There could be regulatory fine which can add to the financial loss that the company needs to bear for the data breach. A data breach could lead to loss of customers adding to the overall financial burden. Additionally, the breach can also make it difficult for an IT company to associate with new clients.
Cryptainer Enterprise Functioning for IT companies
Cypherix’s Cryptainer Enterprise, a data encryption software allows the IT company employees to store data in any format without compromising the productivity of their system. The vault looks like a drive partition in the Windows operating system. The employees can move all their files to the drive through drag-and-drop operation. By saving the files in the vault, all the files are automatically encrypted. The vault is a virtual desk which can be accessed using a passcode generated during encryption. In the absence of the passcode, the data stored is cryptic and illegible for anyone who tries to access the data.
Cryptainer Enterprise software allows you to access all the files in the vault using a single password. In case you forget the password, the administrative module would help you to recover the password once again and access the files. The administrative module is a single point of contact for the company to manage and control data security. It also allows access and control of all the vaults in the company from a single view. Therefore, the changes in data security guides can be easily made in a company without having to make any changes to the encryption software.
The data encryption software also supports secured data communication, in case the employees need to send sensitive data to each other through emails. The same encryption software allows the employees to encrypt the e-mail, which can be only decrypted by the receiver to read it. Cryptainer Enterprise encryption software comes is globally compliant with blowfish and AES strong encryption algorithms. Due to this, it has strong encryption which maintains the data integrity and protects against executables and modifications.
The software can easily run on windows operating system where it also provides command line processing option so that encrypting/decrypting is possible at the dos prompt. The windows user-interface is intuitive and simple and on a single drag-and-drop one can encrypt files and folders of any size in seconds.
Cryptainer Enterprise enhances the data security policies of IT companies by being the additional layer of encryption for employees. The encryption software addresses the hierarchical information segregation sought after by the companies. Irrespective of the individual employees’ passwords, Cryptainer Enterprise’s admin module allows companies to control and maintain data. This enables company to retrieve data in case of a resignation, physical theft or cyberattack. The admins can control the vaults without interfering with the operating systems of the individual owners. This allows companies to modify their data security policies without changing the company software. Using the data encryption software is very important for IT companies as it will safeguard the data against any data breaches.

We live in an era where manufacturing and computer technology breakthroughs are paving the way for major changes in the way people travel from place to place.
For self-driving autonomous cars to communicate with the “Smart Cities” of tomorrow, quantum computing is a key driver.
Quantum computing enables computers to process exponentially greater amounts of information much faster than we can with traditional computers today.
Unlike traditional computing methods, which only translate information into a 1 or a 0, a quantum computer can translate information into multiple states. It can even understand something as being in multiple states at the same time, so instead of a computer bit that is either a 1 or a 0, a quantum bit can be both at once.
If this is all rather mind-blowing, think of it like the difference between a light bulb that’s either on or off, versus a light bulb that can be dimmed. It all boils down to the fact that we can store more information in a quantum bit, or qubit, than we can a traditional computer bit, and process all of it simultaneously.
Google says its mammoth D-Wave 2X quantum computing machine, which it runs in partnership with NASA, has been figuring out algorithms at 100,000,000 times the speed that a traditional computer chip can.
Albert Einstein told us curiosity has its own reason for existing. “The important thing is not to stop questioning,” he said. Automotive companies are also working with NASA to create an opportunity to learn more about the potential of quantum computing to identify quantum-level problems. This helps to ensure automotive engineers designing “Smart Cars for Smart Cities” know how to design the proper scenarios to put to the test. Once engineers understand the right way to ask questions in a quantum framework, there’s no telling the power they will have to solve potential problems in the future as we work to transform our transportation systems.

EV charging smart management to balance the electric grid in a condition of high penetration of distributed generation from renewable energy sources
Following the advent of distributed generation, the electric grid underwent an essential change in power flows. The grid had been designed and developed based on the fact that energy had a unidirectional power flow. Electricity had to be produced in massive power plants from which, through the high voltage (HV) network, the energy had to be transmitted into the consumption areas, where it would reach the end-user, through the medium voltage (MV) network and the low voltage (LV) network.
Currently, the paradigm is modified. We have generation plants, mainly from renewable sources (solar and wind), distributed in the MV/LV network. When the energy produced by these plants is higher than the energy consumed by the end-users present in the local electricity network, the power flow becomes reversed. It goes to the primary substations (HV/MV transformation stations).
The phenomenon of reverse power flow causes instability and safety problems in the electricity grid, like voltage rise, frequency imbalance and tripping equipment, issues that the DSO have to solve to guarantee the continuity of the energy service. To understand the complexity of this phenomenon, we must consider that it is generated mainly by seasonal and non-programmable generation plants, which are strongly influenced by atmospheric conditions, making it very difficult to predict its progression. For this reason, at the dawn of distributed generation, the most widely practised solution was curtailment, i.e. disconnecting generation plants from renewable sources when instability occurred in the electricity grid.
Today, thanks to the process of digitizing the electricity grid, the reaction strategy is changing. The network is equipped with devices that allow remote monitoring and management in real-time. The owners and managers of the grid collect immense amounts of data that are processed by forecasting algorithms, which provide useful information to avoid the emerging of reverse power flow.
An application of this information can be found in Demand Response, a mechanism used for the time-shifting of end-users’ consumption according to the needs of the network. In the first DR, campaigns were considered the loads shifting of the device about 3 kW such as the washing machine or the electric oven since the electric mobility arrived the potential flexibility to be provided has radically changed. An electric vehicle on average can be represented as a 30 kW energy load. Thus allowing EV owners to participate in flexibility market to obtain a full charge from energy generated from renewable sources at advantageous prices by helping the DSO to manage energy flows in the grid, avoiding reverse power flows and smart integrating renewable energies.
This mechanism will be improved and tested during eDREAM project, thanks to different components designed and developed as electricity consumption/production forecasting, baseline flexibility estimation, closed-loop DR verification engine, DR verification and financial settlement, blockchain-driven control for LV networks, in-depth learning forecasting and DR strategies optimization.

BGA Connection Failures
Failure to boot, funny characters on the screen at start up, lights that just flash then go out, freezing and crashing, no lights at all, all these faults can be due to failure of the Ball Grid Array connections between the motherboard and one or more of the big chips. Most commonly due to the graphics processor, this failure is becoming one of the the most common causes of dead laptops. Some Nvidia graphics processors also suffered failure of the connections between the chip itself and the bga carrier - this cannot be repaired without a new graphics chip but is often temporarily fixed by the reflowing hence the common recurrence of the problem after this has been done. We have a Jovy RE-7500 dark infra red BGA rework station and can either reflow the solder or remove, reball and refit the affected chip or a replacement and repair the fault. This is considerably cheaper than replacing the motherboard and usually reclaims a machine that would have been scrapped.
Fancy (and not so fancy) graphics cards can also suffer this problem especially if the fan seizes up - you may think it’s easier to buy a new card, but sometimes it’s less hassle fixing the old card than replacing it especially if it’s an old one in a hard-to-get package.

Spotrack system is patented system that gives followspot functionality to moving lights. It is 3D tracking system that allows single operator to track one stage performer, with up to, 20 moving lights in tracking mode. Spotrack system consists of video camera, computer and DMX interface. Video camera is placed in such position to give overall view of the stage, and video is displayed on computer screen (via TV capture card). Operator is following stage performer with computer mouse on screen, and, in real time, based on mouse position on screen, computer calculates pan and tilt values for each individual moving light, providing them with tracking functionality.
Spotrack system includes 3D stage correction and performer height correction. There are nine areas that can be defined for automatic 3D stage correction. When operator move computer mouse in one of this areas, computer will automatically include correction factor when calculating tilt and pan values. Area "0" is for performer height correction. Spotrack operator is following performer by targeting computer mouse at his/her feet. If this function is not activated, moving light, centre of beam will be at performer feet (stage floor). Activating this function, operator can choose where the centre of beam will be targeting. Performer waist, head or even, over head. Performer height correction is automatically added to 3D stage correction.
Spotrack system is integrated in DMX network. It receives DMX data from light desk and inserts pan and tilt values for each moving light, thus enabling light desk and Spotrack system to control moving lights at the same time. This way, effects, colours, gobos, and all other moving light parameter can be controlled by the light desk. Tracking, pan and tilt values, are controlled by spotrack operator. This functionality provides integration of light effects and tracking functionality, for a "that looks nice" effect.
Spotrack system is 21 DMX channel device. Each moving head can be attached (value >128) or detach (value <128) from tracking at any time, or tracking function, in general (for all moving lights) can be enabled or disabled. This way, for example, we can have only three moving lights in tracking mode during song and seventeen in effect mode (controlled by the light desk), and, at the end of the song we can use all twenty moving lights in tracking mode (all moving lights targeting stage performer).
Based on the performer distance from moving light, computer calculates dimmer value for each moving light. This function can be enabled or disabled.
Moving light calibration is done using two points on the stage floor. Spotrack and light desk operators can calibrate 20 moving lights in 60 minutes.
Spotrack system is modular system; this means that two or more systems can be configured in one show. It is possible to use several spotrack operators and one light desk, so that several performers can be tracked on the stage, individually.
Spotrack operator is free to choose what performer on stage will be tracked with moving lights in real time. During the show, operator can track, singer, guitar player, or it can focus with light, a drummer, back vocals, etc.

Moreover, the mobile apps with services like online shopping, food delivery, and cab services are working on to integrating the chatbots to their apps. It will help the consumers in getting their frequent queries resolved by the bots without calling customer support.In 2019,There will be deploy to serve many new features that will simplify people’s life by assisting them in their day to day tasks.
It is this act of linking blocks into a chain that makes the information stored on a blockchain so trustworthy. Once the data is recorded in a block it cannot be altered without having to change every block that came after it, making it impossible to do so without it being seen by the other participants on the network.Data tyrants are hell scared with the latest technology as it eliminates the scope of data tampering.
Talking about the apps, blockchain technology has already been used by many payment apps for providing trustable and uncompromised safety during the transaction.


Researchers at the University of Michigan have been making headlines of late for their newest invention- the world’s smallest computer. The device – which is so tiny that even a grain of rice can cover it – is only 0.3 mm long. However, since it loses all its programming and data once the power is turned off, experts are not sure whether referring to this ‘microdevice’ as a ‘computer’ should be a wise move. Nevertheless, here is everything that you should know about this latest invention:
How does it work?
Since the device is too small to sport a conventional radio antennae, it uses “visible light” to send and receive data. The light from the base station, and from the device’s own transmission LED, is used to induce currents in its tiny circuits.
How was it made?
The ‘micro-device’ was designed using a precision sensor that converts temperatures into time intervals, defined with electronic pulses.
What is its application/use?
The ‘smallest computer’ will be used for sensing and reporting temperatures, especially in minuscule regions (like a cluster of cells), where traditional instruments for measuring the temperature can’t be used.
The researchers feel that the device can be effectively used to advance efforts in oncology and in evaluating cancer treatments, as tumors may run hotter than normal temperatures.
How accurate is it?
According to David Blaauw, a professor of electrical and computer engineering who led the team behind this breakthrough, the computer can report temperatures with an error of about 32.18° Fahrenheit (0.1° Celsius).
Which company/device held the previous record for the world’s smallest computer?
Before this device was revealed at the 2018 Symposia on VLSI Technology and Circuits, IBM held the record for the tiniest computer measuring 1mm x 1mm.
Prior to IBM’s record, a device named “Michigan Micro Mote” was the smallest computer, which measured 2x2x4 mm. This one, however, had the ability to retain its data and programming even when the power was turned off!

Looking for an in-depth Hoymiles microinverter product review? We’ve got you covered.
The use of solar panels for residential and commercial properties has risen in recent years. To optimize the energy output of solar panels, it is essential to have a reliable inverter system. Inverters convert the direct current (DC) generated by solar panels into alternating current (AC) that can be used by household appliances and fed back into the grid.
The microinverter has gained popularity in recent years- primarily because of its flexibility, reliability, and efficiency. In this review, we will take an in-depth look at the Hoymiles Microinverter and how it compares to other brands on the market.
All About Microinverters
Microinverters are small inverter systems installed behind each solar panel. Unlike traditional string inverters that are installed at a central location, microinverters allow for individual optimization of each panel’s energy output, resulting in higher energy yields.

Frequently Asked Questions
What are the Advantages of microinverters For Homeowners?
Microinverters provide several advantages to homeowners, including increased energy production, improved safety, and better monitoring. Unlike traditional string inverters, microinverters operate independently for each panel, allowing each panel to perform optimally, resulting in higher energy production. Microinverters also improve safety by converting DC to AC at the panel level, reducing the risk of high-voltage DC power on the roof. Additionally, microinverters come with monitoring systems that provide real-time data on system performance, allowing homeowners to track their energy production and quickly identify any issues.
What is the DC/AC Ratio of Hoymiles microinverters?
The DC/AC ratio of Hoymiles microinverters varies depending on the model. However, all Hoymiles microinverters have a high DC/AC ratio, meaning they can convert a high percentage of the DC power generated by solar panels into usable AC power for your home.

No, Hoymiles microinverters are not manufactured in the USA. Hoymiles is a China-based company that manufactures its products in China.
Where Do I Buy a Hoymiles Microinverter?
Hoymiles microinverters are available for purchase through authorized distributors and dealers. These dealers can be found on the Hoymiles website.
Can I Install a Hoymiles Micro Inverter Myself?
Hoymiles recommends that a licensed electrician installs their microinverters. While the installation process is straightforward, it involves electrical work, which can be dangerous if not done correctly. Therefore, hiring a qualified electrician to install the microinverter is best.
What is Derating?
Derating is the process of reducing the power output of an inverter to avoid overheating and ensure optimal performance. Microinverters like Hoymiles can operate at high temperatures. But when the ambient temperature exceeds a certain level, the inverter’s power output is automatically reduced to prevent overheating and damage to the system.
What is MPPT Efficiency?
Maximum Power Point Tracking (MPPT) efficiency is the ability of an inverter to track the optimal voltage and current of a solar panel to achieve maximum energy production. MPPT efficiency is essential because it allows the inverter to convert as much DC power as possible into usable AC power, resulting in higher energy production. Hoymiles microinverters have a high MPPT efficiency, resulting in optimal energy production from your solar panels.

Fujitsu Introduces “LiveTalk” at CEBIT
Fujitsu LiveTalk is a software that, for situations in which multiple people share information, such as meetings or classroom settings, recognizes a speaker’s speech, immediately converts it into text, and displays it on multiple PC screens.
Amongst some trendsetting innovations straight from the Fujitsu Labs in Japan, the Fujitsu LiveTalk solution was one of the highlights experienced at the Fujitsu booth at CEBIT 2017.
This software from Fujitsu has been developing simultaneous interpretation into 19 languages and makes communication in foreign languages blindingly easy. It is a communication tool that translates speaker’s speech into text via speech recognition and displays the content on a PC, tablet, or smartphone screen in real time. The spoken text is smoothly and reliably translated into any language available.
Focusing on the issue of communication with people with hearing disabilities, and based on the technologies of Fujitsu, which has been advancing initiatives in universal design, Fujitsu Social Science Laboratory developed and commercialized LiveTalk, a participatory communications tool for people with hearing disabilities that creates a smoother and more natural communications environment.
We interviewed Mr Michael Erhard head of communication of Fujitsu Central Europe.
- What are the features of Live Talk?
“LiveTalk was originally designed for people with hearing disabilities in Japan. It was developed in a second step for simultaneously translations in many languages and at the moment support 19 languages as for example English, Chinese , Korean, French, Spanish, Arabic, Russian. It is a learning system and it is quick to catch up with the other languages due to its autodidactic skills based supported by artificial intelligence.”
- When it will be available in the market?
“It is the first time we presented this system in Europe. At the moment is available in the Japanese market and we plan to be present in the other markets”.
- What are the ideal customers for this product?
“In the first step some 100 organisations in Japan use this system in order to communicate with disabled people, in particular with people with hearing disabilities, for example hospitals, government offices, businesses and educational institutions. These institutions have to communicate with people with hearing disabilities and they had to use the sign language so only few people were able to communicate. Live talk solved this problem. In particular, the system allows for keyboard input as well as speech input, so that hearing-impaired people can participate fully, alongside speakers of other languages.
Even without a human transcriber or other assistance, which until now has been required when hearing-impaired and hearing people work or learn in the same environment. Another possible application is for example in multinational organisations where the system is able to translate simultaneously in different languages even if multiple participants speak at the same time. ”
- How easy is it to use?
“It is very easy to use, because it can be used directly in the system and no additional hardware is necessary. It support every device with a microphone like PC, tablet, or smartphone. The spoken text is smoothly and reliably translated into any language available. “
- What about the problem related to pronunciation?
“As I explained this system is a learning system with artificial intelligence in the background. The speech is converted into text and displayed on PC screens in real time with speech recognition using handheld and headset mics. If there are any mistakes in the conversion of speech into text, the system allows for keyboard input as well as speech input on the PC. When I tried the system the first time it was poor not so perfect, then I tried a second and a third time and the system got better. Basically a learning system it means the recognition of the voice will be better and better with practice. ”
Extract of the interview:


So I had the bad fuel pump issue this last summer and I replaced it with a new one. I had it running a few times with no problems, now I can't get the bike to start. When I turn the key, I hear the fuel pump prime and all my lights and gauges come on. When I go to hit the start button, I get a buzzing sound coming from the Starter relay under the battery panel. It's making a clicking/buzzing noise. I checked the fuse in there and it seemed fine. Threw a full charge on the battery and that didn't help. Do I need to replace the starter relay? Has anyone else had this problem?
