managed to fry yet another mainboard (not sure what
happened) - I've changed to a different brand / model this time.... it's
heavier - but I've managed to shave the weight off other parts.... the new
controller looks even dorkier.... also wrecked another blade motor (didn't take
well to attacking the metal legs of my kitchen table) - but that's easy to
replace...
total costs for last two days: $57 (not including beer)
good news - bot is back together and working...
