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? Long and skinny, to fit in those rocket tubes.

• Altus Metrum has open hardware and software designs for high powered model rocketry avionics solutions, such as the TeleMetrum altimeter with integrated telemetry link.
• "Taniwha Flight Computer" by Paul Campbell: "the DAC is no longer easily available - we need to lay out a new board for a more modern part"
• "Small Altimeter for Model Rockets" by Herve Cousin
• rocket timer (found via rocket timer) (uses TC4422 "9 A mosfet driver" to power the igniter; but first uses the PIC16F84 to delay the right time ... what are the *other* connectors on the board for?)
• "A miniature 2 meter beacon for rocketry and balloons" by KB0VVQ; "beacon"; "... The tricky bit is running the PIC off the same oscillator. ..."
• "Beeping" Tracking Transmitter Kit
• directional antenna for inexpensive pocket radios

DavidCary is designing a "small rocket computer" that can fit inside an off-the-shelf small model rocket, rather than requiring a "high powered model rocket". One that is as narrow as a 13 mm "mini engine", narrower than a 14 mm AA battery, much less a 18 mm "standard engine".

ideas:

• accelerometer to log the accelerations during flight.
• pressure sensor to measure barometric altitude
• beeper to help find it
• ...
• What other electronics would be useful to put into a small hobby model rocket?
• ...

• 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"

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