Cable Tester BUILD THREAD

Cable Tester Build Thread
CABLETESTER KIT makes ribbon cable testing quick and easy.

Test for shorts and reversed plugs in seconds
Powered by 2 x AAA batteries
PCB size is 4" (100mm) x 4" (100mm). 

Fit all headers so gate cutouts are to the right so pin 1 square solder pad lines up with pin 1 triangle on header.
Fit battery holders so springs are to the right.
Fit Green and Red high brightness leds so long leg goes to square solder pad.
Fit 1k resistor above batteries.
Use one of the 1k cut off legs to link as shown under the pcb to fix pcb error.
Double check all pins are soldered under pcb.
Fit the 6 stand-offs to hold pcb off the bench.
Fit batteries and enjoy. Batteries are not used when no cable is plugged in so no on/off switch is needed.
