Description RGB LED disco light is a simple project designed around PIC16F72 microcontroller. This firmware is a RGB driver, as name suggests it is used to derive or light red, green and blue LEDs in particular fashion. Its main feature is the pattern shown on LEDs. It is quite difficult to describe pattern in words […]

I’m working on a project that requires full orientation information, so I built an Inertial Measurement Unit from scratch. I really like the 9DOF IMU board that Sparkfun makes – the calibration code that comes with it is fantastic – but I wanted to redesign the board so that it could be made at a

UPDATE: I added an alarm function to both versions of the clock. UPDATE: I updated the code so that setting the clock does not affect the seconds accuracy – no resyncing of seconds required. UPDATE: I removed the personal messages from the clock code for the “Pusheen” version in the download links Video at:: http://youtu.be/ikNw1iLE9vg

Despite a low power consumption this relay handles 5A/250VAC while maintaining a considerably long lifetime. If we should mark an electronic component by a term “sympathy”, then the FTR-MY MY relay should be one of adepts …. Why? It´s simply chic. FTR-MY is: ● slim (5mm), so it doesn´t take much time on a PCB
Slim, humble and long-age – this is the Fujitsu FTR-MY relay Read More »
Home This project is to build a portable GPS geared towards runners (well, me and what I think a runner wants a GPS thingy for). It’s sponsored by the University of Minnesota’s ECE Envision Fund. The hardware is basically complete, and the software is functional, if not polished. This is what the main screen looks like

I was frustrated by trying to remember my passwords for all my websites and got even more frustrated when I need to change a password again after some months. Don’t even to mention the needed complexity of them nowadays. A bit insured by the moolti pass featured on hack a day, but too scared of
Researchers at the University of Cambridge have created a new high-temperature superconductor capable of trapping a magnetic field of 17.6 Tesla, improving on a record set over a decade ago. The advance is yet another step toward making superconductors viable for building effective large-scale smart electricity grids, maglev trains and flywheel energy storage. First discovered

This is an AVR ATmega328 based CO2, temperature and humidity logger and meter. It logs data feed, CO2 in air in terms of ppm, temperature and humidity to a xively.com feed. It also display real-time data to user through a 16×2 characters LCD. This logger it is based on the xively logger you can found here: http://davidegironi.blogspot.it/2014/12/a-web-configurable-xively-logger-build.html User can setup the

Idea Build a cheap and simple full software controlled step-up (boost) converter to drive a LED string of 10 LEDs. LEDs are used as string to light up a acrylic engraved plate placed in a holder (also made out 5 layers of lase red black acrylic glass). Step up is from 5V to about 30V,

Higher RF power, GMSK modulation and extra low power consumption make a new communication module interesting even for rough conditions. At cars, chip-tuning usually results in a higher power of a motor. Even the new communication module (transceiver) TR72D from IQRF has passed such „chip-tuning“ of RF portion, resulting in a higher max. RF output
