LED matrix displays are great fun. They are visually charming, and readable from a far viewing distance with a much wider angle of view as compared to many other types of electronics displays. They can display all kinds of information, including text, graphics, and animation. This project is about making a portable Bluetooth-controlled 8×64 monochromatic LED matrix (total

With many switching buck regulators on the market today that are capable of improving an automotive system design it is hard to choose the optimum one for your design. I patricularly like a new Linear Technology solution, the LT8609, a 2A, 42V input synchronous step-down switching regulator because it is unique in that it does
Linear Technology 2A buck converter is 93% efficient at 2MHz Continue Reading
This project is designed to operate with minimum of external components. This amplifier offers high quality and high performance audio at very low distortion. Project is based on nationals LM1875 IC. The IC is thermal and short circuit protected. The LM1875 is a monolithic power amplifier offering very low distortion and high quality performance for
Banguino brings the most popular hobby and DIY development platform in the world into a single chip DTX module and offers full backwards compatibility with the most used worldwide Arduino board – the model ‘Uno’. Bonus features include an on-board power supply to generate +5V and +3.3V to the user’s external circuit, a microSD connector
How to build your own VGA-adapter My lifetime project: building an 8-bit computer using Z80 CPU. This week I had a bad flu and could not do anything useful so I decided to dig up my old plans for this project. I first re-designed many things, like power, CPU-board, IO-board and so on (my old

This project is a Voice echo module with build-in amplifier and on-board mic. A project has been designed around Holteks Ht8970 voice echo IC. Project can be used in various audio systems karaoke, toys, animatronics, show, display, exhibitions, and sound equipment’s. The HT8970 is an echo/surround effect processor. It is designed for various audio
A new power inverter developed at the Oak Ridge National Laboratory (ORNL) marries advances in 3D printing and wide-band semiconductor technology to deliver significantly improved performance in a smaller, lighter package. With further development, it could go a long way toward helping build electric cars that are more powerful and energy-efficient. Power inverters are an
New power inverter could make EVs more powerful and efficient Continue Reading
WinHeist is an electronics component organizer that was developed by a programmer with an electronic habit. It has developed over the years from a personal application used by the author into the full blown application that it is today. To get a look at WinHeist and get an idea of what it is and what
