The function of the device is very simple. Any IR remote than can be programmed to use the Sony protocol will work. The module outputs the device code (TV/VCR/DVD/AUX) and the button pressed, so the device can be used on as many different projects as your remote has devices (usually four). The numeric keys output the number of the key (0 outputs a 0, etc.). The function keys all output unique numbers.[more]

This is a cheap DIY credit card reader project.The reader mechanism consists of magnetic head on a spring mechanism along with low level head signal amplifiers and data slicers. Three signal lines comming from the unit provide card presence, clock, and data.The data from the unit read by PIC12F675 in ASCII format then send to PC via RS232.[more]

MAKE Flickr pool member,Recotana may have built the smallest MIDI input device ever. It uses a PIC12F675 chip, a few basic components, and single switch to register input. He plans to use it in conjunction with a heartbeat sensor - cool! This could come in handy for quite a few project ideas.This project consist of PIC12F675 ,3V coinbattery,2 registor,1 capacitor,1 switch,1 ceralock(20MHz) .[more]

Imagine you are on a shooting range and you want to improve yourshooting skills on a moving target, but the target can’t move. What doyou do? You could for example count the seconds and imagine that the target moves, but this is not a particularly good and accurate solution.The shooting timer provides an audible visualization of a moving target that helps you concentrate and focus on the shooting and not on timekeeping.The shooting timer is a rather simple construction preprogrammed with three types of shooting categories; 25 meter standard pistol, 25 meter fine pistol and terrain pistol. Each category consists of up to three disciplines.This project uses PIC12F675 and internal RC oscillator which is calibrated to be accurate.[more]

Somewhat similar to PIC 12f675 mini protoboard, but extended and with additional boards. Using attiny2313. The scheme is pretty obvious since it only connects attiny2313 with the pins and the only additional elements are resistors and capacitor for reseting the microcontroller.[more]
