Audioguru should have fun with this post; i am preparing to modify my average and somewhat ghetto go-cart with some simple circuits intended to up it's performance a little bit because my neighbor needs to be put in his place. some of the upgrades include:
1.) A high powered, radio crap fan to help cool the eingine
2.) A set of automatic lights for the front
3.) An LED/voltmeter based speed indicator
4.) A set of various gear ratios to give it a Reverse, Nutral, Lo and Hi. none of which it currently has.
5.) A set of headphones, and mics hooked to 2 LM386 audio amplifiers, so the driver and passenger can here each other over the engine
6.) An electronic ignition system (this is'nt too hard, i'm just going to remove one from a similar sized lawn-mower)
7.) this is the one i am haveing a little trouble with, a 2 way radio that is linked to the mics in the headsets that will send a signal back to a fixed location. i want the send to be activeated by a button, and i want the receive to be active as long as the power is on.
I was hoping that audioguru might be able to help with the transmiter and receiver. i was going to use his FM transmiter, but i was slightly unsure of whether or not the transmiter could be bumped to something like 20MHz.
I will be posting my schematics after i have finished them, the firs is most likely going to be the fan. feel free to comment on them and sugest improvements to the circuit to enhance performance, or reliability.
