Elektronika Jobs

I have a commercial IR-band Laser device with essentially two "Modes" - NORMAL and TRAINING, or restricted. Switching between the two can only be accomplished by accessing the Firmware via a proprietary 8-pin connection, for which I do not have a cable or interface. The candidate must either A) build a custom breakout to connect to the proprietary connector, or B) modify the OEM CONTROLLER pad and cable. Once the system is accessed, no custom coding, overwriting, or modification of the firmware will be required; the Candidiate need only identify the language, access the settings, and "flip the switch" between the two settings profiles. The hard part will be creating the connection. Something as simple as a POGO pin may be sufficient, but I am not qualified to say. T...
