Use sound as a transmission sensor? I know it’s not very accurate, but the sound of the engine rises gradually then drops when the gear switches (as you know).
If you can isolate the engine sound from external sounds (maybe with a diff amp keeping CMRR in mind), then maybe it could work…
Bluetooth would be sweet. I am only holding off on Bluetooth right now due to the cost of the modules (a 50$ NES controller isn’t exactly cost efficient!). Hopefully some inexpensive modules will come out and make it a financially feasible option.
Most Newer cars have built in shiftpoints in the computer, IF it is an automatic trans, there is a signal wire that sends the tranny the signal to shift gears I can’t remember Exactally where it may be because of different manufactures, but most cars these days are shifted electronically so it should not be to hard to locate the wire/circuit in even a chiltions manual, which you can get at any auto store. Now for a manual, you could almost use the shift light circuit that come on at pre-determined points depending on RPM or maybe you could dissect that circuit and see if there is anything useful.
Very interesting site. I like the thought of a wireless USB controller. Why not sell them if you are going through the effort of developing them? I am not a hardware buff myself and it seems like some people… you know who I am talking about charge a huge premium to produce an inferior product right now. You could produce something that many people could enjoy for a fraction of the cost. People would not mind paying you a few bucks for your efforts.
Any progress on those Wireless NES controllers? I’ve been scouring the net looking for some way to get this done with little results. These controllers would be great for someone with a HTPC running NES emulation software, but not wanting to deal with the wires from the standard wired USB NES controller mod.

For your Wireless Controller System, you could use Bluetooth, Just an idea, don’t know if it could be easier that way.
