I was wanting to know if anyone had any ideas for a project I was thinking about doing with a spare cordless drill I have laying around.
My idea for the project is to use the drill as either a motor drive, or a steering wheel drive for automatic steering on a vehicle (small childs plastic atv thing possibly).
For either of these projects, I believe I would need to hack into the motor and be able to control the drill speed and/or torque.
I assume that the battery terminals go straight to the motor terminals ( I haven't opened it up yet, as I am still trying to see if this is even possible).
My idea is giving a 12V supply to a motor bridge, then use an arduino to give the motor bridge a PWM signal to modulate the drill's speed, and have the output go into the batter terminals.
If that all seems do-able, then I'd add some sort of encoder to the motor for feedback reference.
Does this seem like a do-able project, and am I missing anything, or does anyone have a better idea of how to do this?
