A "Logic Probe - Next Generation"

An older article, but a good idea... Logic probe on steroids.

Cheap Propeller programmer

Parallax sells the Propeller USB stick PropPlug to program the Propeller MCU. Here is an idea how to make the PropPlug from an Nokia data cable.

Very Accurate LC Meter

Another hobbyist tool, based on "old good" PIC16F84A. A perfect companion to your multimeter.

Component checker / tester

Everyone knows the problem: You have a transistor, but you can't read its signature. Or you can't find the datasheet... You have a diode, but... You have a capacitor, but you can't read... Here is a smarty solution.

TV-based oscilloscope (with ARM7)

This TV-based Oscilloscope is based on a LPC2138 microcontroller application. It can be used to convert a standard television into a high-functioning oscilloscope.

USB Logic Analyzer

Logic analyzer based on Altera FPGA with USB interface.

Z80 In-Circuit Emulator Kit

Do you need to debug a Z80-based computer "in situ"? If yes, this is an ultimate "must-have" tool.


USBPicProg is a simple, open source USB in circuit programmer for Microchip PIC processors.

EASy68K - Editor/Assembler/Simulator for the 68000

EASy68K is a 68000 Structured Assembly Language IDE. EASy68K allows you to edit, assemble and run 68000 programs on a Windows PC. No additional hardware is required. EASy68K is an open source project distributed under the GNU GPL.

LCS-1M: A Low-Cost Hobby Oscilloscope

An oscilloscope is an invaluable tool for anyone working in electronics. LCS-1M is a simple yet full-featured homemade digital sampling oscilloscope.
