PIC Autorange Capacitance Meter

Really powerful autoranged capacitance meter based on PIC16F873. It means users does not need to adjust the range settings. The measuring range is quite large, from 5pF to 2600uF.

PicLA - a very low cost Logic Analyser

A logic analyser using an 18F2525 PIC microprocessor and a PC. The PIC is used as a hardware capture device which monitors the datalines and records all changes. The buffering, triggering, interpretation and display is handled by a PC program running under Windows.


A quick prototyping system that will plug into a breadboard without taking up too much space


Your own easy to build high performance logic analyzer for less than 10$.

ICD2 clone

In-Circuit-Debugger for MPLAB-6 and higher

Programmable Power Supply

Programmable power supply 0.8 - 15V with PIC micro


Undoubtedly s'worlds smallest and simplest oscilloscope! An 8 pins PIC processor samples the analog input signal and generates a (PAL) video signal which shows the waveform on a normal television set.
