8 Pin PIC12C508A and PIC16F84 programmer circuit
This project is designed to program the 8-pin PIC12c508A and 18pin PIC16F84 microcontroller chips to support the projects we have designed, however it will also...
508A microcontroller can deliver a maximum of 25mA
A typical device that requires less than 5v and draws less than 25mA is an LED. A LED must be supplied with an exact voltage for it to operate correctly. Becaus...

WLoader - a 16f877 application loader
If the piclist is an any indication the 16f877 seems to be the new favorite hobby microcontroller, a position that used to be occupied by the 16f84/16c84. Compa...

Wisp628
Wisp628 is designed to be used as an in-circuit programmer only, hence no socket is provided for the target chip. `Why use such a limited design`, you might ask...

AVR programmer
To program some AVR microcontroller unit (MCU) you will need an AVR programmer. The better way to do that, is to buy some development kit like STK-500. This kit...
