cycle electronics

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?

small rocket computer

What kind of electronics are small enough to fit into a small hobby model rocket?

See rocket computer.

bicycle computer

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.

• "Build a simple bike computer: Learn how to program a PIC by Fred Maher

• 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?

• oBiCo: the open bicycle computer: ARM9 processor and ATMEGA88 processor; Micro-SD Interface; plays MP3, OGG, etc. files; TFT-color display; 3 axis accelerometer; battery charged by dynamo or USB; Logging your tour data like GPS coordinates, heart frequency, speed and other parameters to a MicroSD-Card. The p2pfoundation wiki discusses the open bicycle computer

• OpenMoko: use of the Neo1973 and tangoGPS as a bicycle computer

• "Sensors Linked To On-Board Bicycle Computer Could Make Riding Easier"

• BEHEMOTH (Big Electronic Human-Energized Machine... Only Too Heavy).
• Winnebiko II: primary design objective -- being able to type while riding a bike

• Spoke-POV POV display.

• LifeTrac -- the world's first open-source high-performance four-wheel-drive tractor
• EV production wiki discusses several electric open source vehicles.
• the OScar project is developing an open-source automobile. Will it get its own wiki? perhaps at Open Source Ecology: Open Source Car?
• "c,mm,n", the world's first open-source car (via the Guardian)
• the Electric Unicycle: the eunicycle.
• heads-up display in a motorcycle helmet[1]
• OpenUAV, Open Source UAV Project: "All source code/hardware schematics are open source (GPL) and can be freely downloaded from this site."
• DIY advanced high performance electric vehicle conversion project. The stop light text matrix is a pretty cool project all by itself.
• "Smart Brake Light System Would Provide More Information To Drivers"
• Openflight http://openflight.org/ wiki: "Crowdsourcing the flying car - collaborative design of flying cars"

• Massmind: "PIC_k You Brains" has a long thread on a rocket-launch computer including a big count-down display, ignition control, and various safety features.
• "Mikrokopter" AVR powered quadrocopter.
• Infineon has information on "Automotive Electronics"
• Panacea University has several open-source projects, some of them involving vehicle electronics.
• Endless-sphere.com: Electric Vehicle Technology Forums
• 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/ ?
• 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.
