     .: Single Chip Temperature Data Logger

     

     

     

    A data logger is a device that records measurements over time. The measurements could be any physical variable like temperature, pressure, voltage, humidity, etc. This project describes how to build a mini logger that records surrounding temperature values. It has following features... more


     .: Motorcycle Universal Gear Indicator

     

     

     

    This is a new design for a universal gear indicator that can be fitted to any motorcycle as an aftermarket accessory. Its main advantage is that its operation depends entirely on the gear shift lever movement, instead of connecting to speedometer ... more


     .: USB Sound Card with PCM2702

     

     

     

    Make a sound card is no more a complex issue. If you use great IC PCM2702 from BURR BROWN / Texas Instruments you can create a fully functional USB sound card. This sound card can be powered from USB port and has one stereo output. You don't need to install any driver for Windows XP and Vista, because they are already inside. This is really plug and play. more

     


     .: PCB Exposure Box with Fluorescent Lamps and countdown

     

     

     

    Tired of spending hours and hours in wire soldering? Do your circuits look ugly and you are looking for a way to produce professional-like PCBs? Then you had better try photoetching. And the first step to do that is to have the right equipment that is an Automated Exposure Box. Moreover if you like tinkering with microcontrollers, here is the challenge. more in English more in Greek

     


     .: 89Sxx Development Board

     

     

     

    This is single side development board with In System Programmable Flash based microcontroller, 89Sxx series. Dominikus have designed this single side development board to be used as a tool for learning MCS-51 Microcontrollers, and for easy microcontroller project development. more


     .: PIC based WWVB clock
     

     

     

     There are many DIY versions of WWVB clock designs available on the web. Commercial "atomic" clocks are inexpensive and widely available, but I wanted to try my hand at designing one to gain insight into WWVB reception and to learn a little about programming a PIC microcontroller. more


     .: Toggle ON / OFF Switch
     

     

     

    This project describes how to build a "soft touch" switch. By "soft touch" we mean that you have to push once to set device ON and push again to set device OFF. This kind of switch works by latching a relay to ON state with push of a button and with another push latch is released. more


     .: IR remote extender
     

     

     

    This project describes how to build an IR remote control extender / repeater to control your electronic appliances from a remote location. An IR detector module receives IR signal from remote control and two IR leds are re-emitting the signal to the appliance. You can place the IR emitting leds close to the device you would like to control using some wire and keep main unit close to remote control location. more
