Link to source and schematics Open source hardware and software implementing OBDII tester for cars. Two versions one using a PIC microcontroller and one using an AVR microcontroller.
I have created a web site where I am going to post my projects, mostly electronic but also some software. So, to start, if anyone like to enhance tail light on his motorcycle - welcome to BoldLine.org.
P.S. I don't know if you guys have a some kind of formatting standard here. So, if I posted this incorrectly could someone correct me, please?

What kind of electronics are small enough to fit into a small hobby model rocket?
See rocket computer.
RCAP: R/C Auto Pilot: Remote Control Auto Pilot
"The RCAP2 is a Remote Control AutoPilot] for model airplanes, cars and boats. The autopilot function can be switched off or on during flight with the flick of a switch." Uses PIC16F876A to:
- read (servo) commands from the RC server
- read (RS-232) GPS location from a NMEA capable GPS (with programmable goto/waypoints functions)
- drive (servo) commands to the rudder.
What sort of electronics are useful mounted to a bicycle? Does it make any sense to mount the display on the bicycle helmet rather than on the handlebars?
- speed (miles, kilometers, and wheel RPM), trip distance covered, trip time, total distance (odometer), elapsed time and calories burned.
- pedal rpm == pedals per minute
- beep every 10 minutes to remind me to get a drink of water
- torque, force, power, etc.
- The CycleRecorder Project: "open source hardware and software project started by ... Robert Fitzsimons. The main goal of the project is to develop a modular and portable platform suitable for use with a bicycle, which can be used to record various aspects of a cyclists journey." ... used the open source tools gschem and pcb ... (also links to several similar projects)

- A data logging tool for the bicycle by Wolfgang Strobl 1998: a PIC processor that interfaces between a reed contact (wheel revolution sensor) and a standard serial interface (to a handheld computer or PDA). mentions connector problems -- have USB connectors solved this problem?

- MegaSquirt aftermarket electronic fuel injection (EFI) controller is relatively "open" hardware -- the source code and schematics are available for troubleshooting and modification and educational purposes, but not for copying -- they can be freely downloaded from the MegaSquirt website. See also the MegaSquirt HowTos at Wikibooks: "BMW E30 Megasquirt & Wasted Spark ECU Convertion" and Wikibooks: "Nissan 240SX Performance Modification" and the DIYEFI wiki and the DIY-EFI wiki
- VEMS Wiki discusses a Versatile Engine Management System
- SourceForge: FreeEMS: A free and open source Engine Management System including both hardware and software design. Also has a FreeEMS wiki. Apparently somehow related to http://DIYEFI.org/ ? Is there a more recent version of the information in the 2008 backup?
- RCAP2 is a Remote Control AutoPilot for model airplanes, cars and boats. Uses a PIC16F876 to interface between a GPS serial port and RC servo motors. Mike Pawlowski released the original version as open hardware. Also uses a PIC bootloader. RCAP firmware at Sourceforge.
- Xarias is an embedded car computer system. It reads data directly from the sensors -- speed, rpm, fuel injectors, etc -- and displays speed, fuel consumption, engine RPM, internal and external temperature, journey time, distance, average speed and fuel consumption, total fuel consumed, cost, etc. Xarias is based on the Atmel ATMega32 MCU. The firmware is in C and is open source (GPL). All PCBs were designed using open-source gEDA software (schematic and PCB layout).
