Programmable Chip EEG
The Programmable Chip EEG is a dual 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
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.
Home controller
Program your appliances to operate automatically in conjunction with your weekly and daily schedule, manually turn them on/off from your PC or use the controller as a process ON/OFF controller to regulate some kind of physical variable to the desired value.
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.
