less tape, i was the tutorial. for the castor( i use the same one a lot) hot glue or wood glue on the bottom works fine and the screw holes are very useful.

That one can be simplified, just make a 4 mosfet h-bridge using logic level mosfets. 4 components, that is it.

That was my original plan and one i would have recommended but i can not find any decent shematics for a Mosfet H-Bridge.

Do you have one?
