I spotted this fancy ceiling illumination in the Children’s Museum of Pittsburgh while there for the Pittsburgh Mini Maker Faire. The LEDs are connected to ribbon cables that attach to an EMSL Peggy 2 board similar to the one we sell in the Maker Shed (we sell the smaller Peggy2 LE version.)

The Peggy 2 is capable of individually addressing 625 LEDs arranged in a 25 x 25 grid. That means there should be 25 – 50 conductor ribbon cables attached to this one. I don’t know who soldered this, how long it took, or how they kept their wires straight but I’m truly impressed. Great work whoever you are!

When not working for Make I can be found falling off my unicycle, running in adverse weather conditions, skiing down the nearest hill, restoring vintage motorcycles, or working on my car.
