The DAQ's digital outputs, being driven by Nick's LabView program, are now providing the timing for the motor. This means the Linux-based laptop and serial port arrangement is obsolete.
Since the outputs are very much current limited, a transistor board was assembled. A NPN, setup as a NOT gate is chained to a PNP setup as a switch. This provides a common ground, separated positive voltage needed to go into the launch controller. This setup also drives some LEDs on the board. Pictures and schematic to follow, but its based off of http://www.kpsec.freeuk.com/trancirc.htm
