I had some more thoughts (amazing, eh? :lol: )...
This sounds like a good microcontroller application for a few reasons: Your CS background would help with sofware development, the finished product could be in-sytem programmable via a laptop, and the hardware itself would be simpler to...
Cool project. I'm a bike racing fan, also.
Reading your post, I immediately thought of this book:

It's a good general electronics primer but goes beyond that to give you an...
On all trailer lights I've seen, that one lamp on each side is dual filament...one for brake and one for turn. I'm sure this project can be done but it seems like a complication of a simple problem.
I think I understand what you are trying to do, but I'm afraid your diagram does not make sense to me. :(
Is there no chance of using two lamps in each circuit, one for brake and one for turn signal? Or...allowing the single lamp to be turned on by the brake or turn signal would me much...
Check out the truth table in this datasheet: https://www.fairchildsemi.com/ds/CD/CD4013BC.pdf
If Set is asserted (high) and Reset is not, then Q is high and Qnot is low.
If Reset is asserted and Set is not, then Q is low and Qnot is high.
If both Set and Reset are asserted, both Q and...
I also recommend the AVR. The only drawback to the AVR right now is the relative lack of instructional material. However, there are enough good resources to get going. A very good first step would be to visit: **broken link removed** where they have some beginner tutorials that will explain...
See the circuit titled "Low Power Pulse Generator" in this document:
https://www.electro-tech-online.com/custompdfs/2003/11/sdla006a.pdf
Your first stage will have a period of 1.25sec and becomes the trigger for the second, which will have a pulse width of 1sec.
You can download the "Lite" version of Orcad for free.
Or you can also download ExpressPCB's software, which is a layout program and schematic drawing program, also for free. https://www.expresspcb.com
Texas Instruments and others make ICs designed for this purpose, such as the UC3909 (for lead-acid batteries): https://www.electro-tech-online.com/custompdfs/2003/11/uc3909.pdf
And here's an app note describing how it's used:https://www.electro-tech-online.com/custompdfs/2003/11/slua058.pdf
Wilfred,
After having another look at it, I'm not sure the circuit I gave you will work. I'm sure that the relay for the Brown wire is correct, but I think the relay for the Green wire will cause some trouble. Here's why: the Green wire must be grounded for the engine to start (gets to...
I'll make the assumption that the engine is killed by grounding the black wire. This is typical in small engines, i.e. grounding the magneto to kill ignition. So: Kill=Black wire grounded, Run=Black wire open
The Green wire is the primary ground for the starter solenoid. Also, since the seat...
