Hi: I don't know anything about RC controls. But, I need a real, real simple system. Like a keyless entry for a car, I need a simple momentary "on-off" push button that will then control a relay or power transistor to switch 3.6V DC "on" to run a small motor. When the button on the "fob" is released, the relay/transistor shuts "off." No timers needed. The range isn't going to be over 3 feet. The motor will draw a max of 1.2 A. Size and power efficiency are the most important. I'll be using a CR2 battery to run the motor, and whatever coin battery is needed for the transmitter and receiver. Maybe the CR2 can run the receiver as well without causing a continuous drain?
The receiver and motor will be contained in an aluminum housing. However, I could make one end piece of the assembly from plastic so that the receiver would work. I really don't want an antenna dangling about.
Can anyone design and build a prototype for me? I'll pay whatever is reasonable.
Thanks so much!
Don
