This ingenious LED wiring jig was made by Dan Blickensderfer who hails from the USA.
He came up with it as a way of spacing the LEDs at regular intervals and keeping the wiring very neat.
The basic details are below, but you can check out Dan’s web site (Ohio Lights) for the full story.
The LEDs are held in place using wooden clothes pegs attached at regular intervals to a strip of wood.
Soldering the common anode wire.
Adding one cathode (channel) wire per LED.
Dressing the wiring neatly.
Taken out of jig.
The end result. Fantastic!
