An ultimate AVR MP3 player design
23. December 2008 - 18:22 — adminAn evolution of the homebrew MP3 player - if you are interested in building your own, here is all you need.
Simple CPLD dev board
22. December 2008 - 22:34 — adminA home-etchable, self programming development board to get you started with the CPLDs.
Z80 Microcomputer
18. December 2008 - 23:04 — adminThis is an actual computer, built completely from scratch. I began the project in the spring of 2006, while I was taking a course on microcomputers. My Z80 system will remain a work in progress as long as I can think of new things to add to it.
cosam.org - Z80 Project
18. December 2008 - 5:35 — adminAfter several years' worth of interruptions and procrastination, the homebrew computer project has finally become a reality. Now on the forth revision of the design, the system actually works! As this page seems to be getting its fair share of traffic lately, I'm trying to keep it reasonably up-to-date. I've also published all of the Z80 project's source code in my online source code repisitory. However, don't be shy to drop me a line if you have specific questions or would like to discuss your own project.
Web server on a business card
16. December 2008 - 2:56 — adminThis mini web server is slightly smaller than a business card. There are a lot of tiny one-board servers out there, but this is probably the smallest you can etch and solder at home. Unlike many embedded web servers, files are stored on a PC-readable SD card, not in a difficult-to-write EEPROM.
The Bus Pirate/Universal Serial Interface
15. December 2008 - 8:07 — adminVery cute idea I like – a universal bus interface that talks to most chips from a PC serial terminal. It deserve to rework!
Infrared repeater
13. December 2008 - 23:38 — adminMCU based infrared repeater allow to control an A/V equipment that is behind a wall.
