Project partner K and I worked on the actual coats part of the LED blinky coats in a couple of recent work sessions.

K opened the linings, and we put Gorilla Tape over all the points where the LEDs will poke through the lining and through the fur. Then we drilled (with a normal 1/2″ bit). Lots of drilling, 200 holes per coat x 3 coats.

Then we pushed the LEDs through the holes, and (not shown) taped the extra loops together to hold the LEDs tightly against the fur (they tend to dangle out).

The effect is great, though I haven’t managed to get the actual Arduino to work with the LEDs in place yet. There have been two more minor smoke release incidents. Debugging is proceeding.
