those are all very good ideas but do not quite have enough work involved.
ive found all the electronics i need atm. i think i might stick with the amp idea. ive found the control unit, main chip, remote reverb control, a chip that somehow can 4x the power of the speaker using the same current and voltage but sorta havent found the power supply.
most other people are doing r/c things e.g. cars.
somebody is already doing a multi effects pedal so i wont be able to do it. only for the sheer fact that everyones has to be different.
ive thought of making a car with air suspension but it seemed too complicated controlling it.
PS: i forgot to mention that we just buy the circuits, assemble, then make the rest by hand.
thats why some people are just buying r/c cars and making thier own chassis
