“I often get asked about bicycle maintenance and repairs, and tips for how to ride efficiently. This little manual is intended as a summary of what I have learned over the years. I am not a professional mechanic.

Thomas Driemeyer – Bicycle Guide

All of what I say here is the result of personal experience and opinion and may in places flatly contradict professional techniques, but it has served me well. I offer no guarantees that it will work for you. If your bicycle falls apart because I said something wrong, you are on your own.” – Thomas Driemeyer .

Computer-controlled LED lamp

Computer-controlled LED lamp

This page shows how to build a lamp using this module that can be programmed to show any color or cycle of colors, as instructed by a PC or Mac over a serial RS232 line. (Or USB, using a cheap USB-to-serial adapter – unfortunately USB cables cannot be longer than about two meters before they become either unreliable or very expensive.)

Bicycle Light Projects

Constructing or modifying a bicycle lighting system should be done carefully to enhance the lighting and not displace a minimum lighting that is needed for safety.In rural areas and mountain bikes more lighting may be needed.

Dynamo LED light electronics – A nice selection of electronic circuits to power LEDs from a bicycle dynamo

Battery LED light electronics – A basic step-up circuit to power an LED from a battery

  • Universal single-LED headlight
  • Universal triple-LED headlight
  • Universal LED taillight mechanical construction

This is a educative and simple example to help learn about supercaps and white LED. It will also help you understand component behavior. If you are learning electronics, try this one out.

The goldcap-Dynamo Lamp idea is a DIY Tutorial by Kainka on Electrical Energy Harvesting. What may be this EH Thing ?

Supercap and White LED and Energy Harvesters

Energy harvesting (also known as power harvesting or energy scavenging) is the process by which energy is derived from external sources (e.g., solar power, thermal energy, wind energy, salinity gradients, and kinetic energy), captured, and stored for small, wireless autonomous devices, like those used in wearable electronics and wireless sensor networks. – EH at Wikipedia

Then the Cycle Dynamo may not be the ideal choice for furthering this research. The reason being, this is quite a powerful source of energy, especially when going downhill!

 Electric Double Layer Capacitor – EDLC

We need a more fussy source of Electricity. Like the waves of the sea, that could splash onto Large plates of Springy Beryllium Copper Cantilevers, which moves an Array of Magnets in coils (Reverse of Solenoids). This gives Random Spurts of High Energy Pulses which have to be Harvested.

Piezoelectric Energy Harvester – Mide Technology

That is for you to dare and do …….. Now let me give some things you can read, before you start this epic Adventure…

Electric double layer capacitor an eFlywheel

Now Move ! There is so much Abundant Energy to be Harvested. You can Even Setup a Roadside Electric Trike Recharging Station. – Gomier Electric Tricycle

We need more contests, An LED Lighting Contest and a Sponsored Elekrik Vehicle (Non-Car) Super-Contest.
