Hi, so I eventually got a layout & schematic for the CDI up on the "High Performance Tips" section. I have noticed that some people seem to like the idea of indicator's for their bikes & that a simple, roll ur own system hasnt been posted. Sooo, I have put together a prototype built around 2 common & cheap transistors, a PN100 & a PN200, using 5 resistors (1/2 watt), a minature trim pot (to control flash rate) & a 100uf/16V electrolytic capacitor. The whole thing, constructed on vero board is about the size of a small postage stamp, or 3/4" x 3/4", & about 1/4" thick. Running on 6V, it is designed to flash a #47 type 6V bulb, which is the type used in old pinball machines so should be bright enough. 2 units would be needed to have front & rear indicators using these bulbs, or just 1 unit if u used 0.4watt 6V bulbs. All up the prototype cost $2 to construct. I have just tested for 5 minutes to make sure it works, so now I'll run it for a few days then post the schematic.
I chose 6V to power so that a rechargeable battery can be used & charged off the white wire. Cheers
