“Very cool. But even cooler with RGB LEDs.
These are very nicely made and great looking little badges. I put together a couple of these as gifts for kids old enough not to chew on them or swallow the pin clasps. Rather than settle for one color LEDs I used 3mm slow fading RGB lamps and they work great. Assuming kids might be tempted to stare at the blinky lights and not wanting to damage any retinas I cut the outer traces and soldered a 10K resistor on each side, with one lead in each anode hole and the other in each battery holder hole. This dims things down to a comfortable level. Others may want to use higher or lower values or none at all, depending on individual taste. The LEDs I used stay in sync remarkably well and the effect adds to the fun.”
“I love the idea of offering 3 different LED colors. It is very easy to assemble with simple and detailed instructions. And super fun to wear. No disadvantages so far. Thanks, Pimoroni!”
