Projects

ARMUS Embedded Linux Board

An ARM920T board running Linux at 200 Mips with sound, Ethernet, CAN, 48+ bidirectionnal IOs and 4 DSPs for motor control (DC, Servos, etc...). Built as a student proof robotics design platform.

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!

RS232 Dev Board

A simple RS232 example project that takes all the power it needs from the serial port. Use it to power your microcontroller and communicate between serial port and microcontroller. Takes advantage of the fact that pc serial ports will accept 0-5V rather than the RS232 standard of around negative 10V to positive 10V. Very convenient - no external power required! Note that you may use either a 5.1V zener or a 5V regulator.
Another version, using a zener - I recently ordered a pcb for this one:
The thick blue lines represent a bus which contains all the important signals. I hope to update this again once I try my board.

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.

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.
