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?

Welcome. --DavidCary 14:38, 23 July 2007 (PDT)

small rocket computer

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.

RCAP Documentation at Wikibooks , and RCAP PCB layout at Sourceforge .

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.

• 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.
