	It may be possible to take multiple related circuits and merge them into one PCB. It's then feasible to make many prints of that one board.		It may be possible to take multiple related circuits and merge them into one PCB. It's then feasible to make many prints of that one board.

	I think there should be a gear protruding from the module. This can seat inside something (like a pulley) or mesh with another gear. It means that the module can slide in horizontally without needing to attach belts or chains.		I think there should be a gear protruding from the module.

			=== ICE ===
			Preference for diesel, but it could also be gas, or we could do a base engine block and have it convert to either. This really doesn't need need to be built from the ground up, it should be designed for the most commonly available replacement parts. And it should really be parametric.

	I think my preference is for something like an NMTB taper driven by dogs rather than something like a Morse Taper with a tang. If something goes wrong, it seems like this would be easier to fix. On the collets I'm not sure between something like ER (probably 32) and R8. The R8 is longer and that seems like it would be more stable, but if that's not useful it could be wasted. CAT40 ER32 is available for less than $40 with another $50 for a set of collets.

	I'm also starting to see the appeal of ODrive. The ESC is already $100, adding a bit more for precision control doesn't seem like a bad deal.		I'm also starting to see the appeal of ODrive. The ESC is already $100, adding a bit more for precision control doesn't seem like a bad deal.

			I do need to pay attention to the torque, even a high power motor may not have enough torque (particularly at low speeds).

	This might be a winner. If the specs are accurate, I can get 4KW from a 2lb motor (plus an esc). And we can simply limit it's power when on 110V@15A. Lots of features we'll need; speed and power control, braking. I can put the power and esc electronics in a separate box with one cord so the motor can be used in hand tools.		This might be a winner.
