Programmable Chip EEG
The Programmable Chip EEG is a Multi-channel electroencephalograph that could be a brain-computer interface.
Open Mobile Gadgets
An open source, open hardware mobile phone in its preliminary development.
Music Players including MP3 players
TRAXMOD Open source MOD music player for dsPIC/ARM microcontrollers.
PG31 GPS RS232 Dev Board
A simple RS232 example project that takes 3.3V TTL serial and outputs to a super-common RS232 connection. Insto-NMEA!
PG31 GPS USB Dev Board
A great example project using the CP2102 USB to TTL UART IC as well as some basic battery holder info.
Chalk Roach
Ultra simple microcontroller development board for Atmel ATmega32 = 16MHz, 2KB SRAM, 16KB Flash
#6
Son of Chalk Roach
LED displays
- 24" Wall Clock A really big wall clock. Why? Well, cause it might look cool? Probably not. But we do use GPS to get the time! Groovy.
- POV display that spins around, giving the illusion of a large display. (DavidCary)
Cellular Rotary Phone
An indepth breakdown of the Port-O-Rotary. Some clues to help you avoid audio problems with the GM862.
Das Brewmeister!
An attempt to wirelessly monitor temperatures of fermentation vessels
Fermenter Controller
A web available fermenter vessel controller. Uses PICs, i2c, Rs232 and python.
ffff
Interactive Lock Box
An interesting project using an accelerometer and capacitive touch ICs.
Motor driver (H-bridge)
Atomic Microscope
An atomic-resolution microscope.
- STM (scanning tunnelling microscope)
- AFM (atomic force microscope)
BlueICE
A bluetooth JTAG ICE debugger for AVR's!!!
Sortof-Networked RFID Reader
A 125Khz RFID Reader with a simple RS232 based ring network - to allow connection of multiple units to the same control computer.
Consider using "RS-232D", aka "EIA/TIA-561". It has all the same wires and voltages as RS-232, but specifies a RJ45 connector.
Also consider RS-485.
(What is the name of the standard for RS-485 on RJ14 ("4 wire RJ-11") or RJ45 ?)
Battery charger
See "Build A Smart Battery Charger Using A Single-Transistor Circuit" by Ejaz ur Rehman. But be sure to read the "Reader Comments" at the end. The suggestion to add a zener diode is a good idea.
the Open Graphics Project
the Open Graphics Project a project started by chip-designer Timothy Miller. His goal, along with the rest of the project, known as the “Open Graphics Foundation” is to make a 3D accelerated video card which is fully documented, free-licensed, and open source. See the Open Graphics wiki.
