This project it is based around a PIC16F627 micro and It is build as a countdown timer for a UV exposure box for PCB development that uses fluorescent UV lamp with following features:
Adjustable time in 15-second increments (up to 10 minutes)
Lamp preheat feature
Two button operation (with audible feedback)
Countdown alarm (when timer reaches zero)
Relay for [...]
This driver may be used for a 3 Axis CNC Machine. Based on the PIC16F870, for 3x Unipolar(5, 6 or 8 wire) Stepper Motors. It provides Full Stepping for good torque, with ability to toggle auto-shutdown of motor coils, which allows the motors and current regulation device to run cooler and require a lower output [...]

How many times have you wished that you recorder your recent telephone conversation? I have, many many times. So thanks to [Trax] that he finally decided to make this happen by using PC and a piece of hardware (powered from USB) to record audio from phone line to MP3 format. He wanted this thing to [...]
The 78xx family is a very popular choice for many electronic circuits which require a regulated power supply, due to their ease of use and relative cheapness. When specifying individual ICs within this family, the xx is replaced with a two-digit number, which indicates the output voltage the particular device is designed to provide (for [...]
