Alright, everyone's heard of how to easily add RF control to your device, gut a 5$ remote car. I recently came across another sweet idea, gut a cordless phone with a page handset button. https://www.angelfire.com/80s/sixmhz/rcphone.html
I need some lights to wireless flash with some music. I'm thinking of splitting the stereo signal into two stereo signals. Send one to the speakers and the other I'll convert to mono. Then take the mono signal and use that to drive a transistor in place of the page button (the transistor is the new switch). This should effectively be the same as tapping on the page handset button in tune with the music. Then gut all the crap from the handset and replace the speaker with another transistor which will act as a switch for my lights. The only flaw I see is the response time of the handset and how it reacts. If there is even a one second delay, the lights will be noticeably out of sync. And if the handset speaker is suppose to buzz in three short bursts when you hit the page button (for example) then it won't work. (The lights would flash three times for each beat in the song and be horrible out of sync).
I guess this is a dual thread.
Thread 1
Cordless handset = wireless trigger. Clever idea, yea? Can we make it better? Improve response times?
Thread 2
Make my wireless light idea not suck (I can't use a mic). I think everything I posted will work, its just finding a phone/car/something with a good response time. Now that I mention it, I have some ZipZap toy cars from RadioShack (those were the bomb a few years back) that no longer work. Maybe I'll gut them.
