Add Some Blinkenlights To Your Supercon Badge

We’re not sure what is more amazing here: the glow of the blinkenlights themselves, the tedium involved in creating it, or the fact that [makeTVee] soldered 280 microscopic WS2812 LEDs while at Supercon.

This hack began before the con when [makeTVee] designed the LED-diffusing frame in Fusion 360 and printed it in clear resin. Rather than solder the LEDs straight, the frame has 280 teeth that support each one at a 55° angle.

Not only does this look cool, it makes the bridging of DOUT to DIN much easier. That leaves GND and VCC to be painstakingly connected with 30 AWG wire. How, you might ask? With a little help from 3.5x magnifying glasses and the smallest soldering iron tip available, of course.

But that’s not all. Since 280 addressable LEDs need a lot of power, [makeTVee] also designed a holder for the LiPo battery pack that fits into the existing AA holders.
