My husband decided to go see his friend at his automobile shop. We couldn’t resist access to some really nice equipment so he and his friend cut out the part of a shelf on which the heat sink holding the LEDs will be placed.
I discussed the design of the LEDs in a previous post.
One thing I noticed about the LED connectors – the two I bought most recently from Digikey (part # 0688014084 @ $1.39) had the nice, thick wire to solder together. The earlier connector did not (part # 0688014146 1 @ $.97) Yet they are both called “PICO-EZMATE HARNESS FOR VERO 6”. But WOW! A $.31 price premium for the thick wires is a bit much!
I marked the location to place the LEDs on the heat sink based on my design in Fusion 360:
I then cleaned the heat sink with hydrogen peroxide.
The BoM for this part:

|Heat Sink||1||Heatsinkusa||Heatsinkusa.com||20″ x 7.984||$28.80||$18.77||$5||$52.57|

I got to wiring the LEDs up and then stopped for the day.
