A DNA Lamp That Uses the Full Genetic Code of Humanity

Nice build + write-up from maker David Fricke.

Fun to see our Adafruit ItsyBitsy 32u4 – 3V 8MHz incorporated into the project.

This LED lamp lights up the room with the full genetic code of humanity. It slowly reads off the DNA code from an SD card and displays the genetic base pairs as colors that move up through the helix. The four bases—A, T, G, and C— are represented as red, purple, green, and blue respectively. It has a power button as well as speed and brightness dials on the base. For the helix structure, I tried to make the proportions as close as I could to actual DNA. It’s a fun lamp to get lost in thought staring at. Because there are roughly three billion base pairs, it takes a long, long, long time to go through the whole thing.
