Yeah, I can pull enough current to light a red LED,
Through what? From where?
so that's got to be close to 150mA.
A standard red LED will shine quite brightly on 1/10th of that and melt on 1/5th of that.
I was thinking an NPN transistor for the switch control. I'm trying to learn more about them. The trigger uses a simple push button, similar to the Arduino Uno reset button. I think I could patch my transistor between the push button and the motor.
Pictures and diagrams would help.
I'm waiting for the carbon brush to arrive by mail,
We're all waiting on some definite information, so that we don't have to guess what you're trying to do.
