I'm using Nicholas C Lewis' [http://nicholasclewis.com/projects/inkshield/\|InkShield] device to control a HP C6602 cartidge for now - it was just wire up & go, and will allow me to test my axis control and firmware.

			After blowing up the MC34063A on the board, I made the following modifications, and it pulls less current and runs slightly warm - not burning hot:

			* U1 - MC34063EBN
			* R1 - 1 Ohm
			* C2 - 100pF

			Well, lookey here! The Canon BJC-4550 printhead, control assembly, and wipe/cap assembly (not pictured, but it'd be in the space on the far right) perfectly fit on my powerbed frame!

			I do believe I have a winner!
