Very Accurate LC Meter
21. November 2009 - 15:46 — adminAnother hobbyist tool, based on "old good" PIC16F84A. A perfect companion to your multimeter.

Component checker / tester
9. October 2009 - 18:57 — adminEveryone 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)
28. September 2009 - 16:54 — adminThis 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
13. September 2009 - 14:54 — adminLogic analyzer based on Altera FPGA with USB interface.

Z80 In-Circuit Emulator Kit
20. July 2009 - 19:28 — adminDo you need to debug a Z80-based computer "in situ"? If yes, this is an ultimate "must-have" tool.

USBPicProg
25. June 2009 - 20:08 — adminUSBPicProg is a simple, open source USB in circuit programmer for Microchip PIC processors.

EASy68K - Editor/Assembler/Simulator for the 68000
21. November 2008 - 18:39 — adminEASy68K 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
6. November 2008 - 18:06 — adminAn oscilloscope is an invaluable tool for anyone working in electronics. LCS-1M is a simple yet full-featured homemade digital sampling oscilloscope.
PIC Autorange Capacitance Meter
18. September 2008 - 17:17 — adminReally 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
30. August 2008 - 21:28 — adminA 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.
