NeoPixel Glass Skull Lighting Effect (A.K.A Mr. BlinkySkull) #NeoPixels

Dan Ternes shared a fun NeoPixel Glass Skull project he created with a NeoPixel ring and an Arduino Pro Mini: “The setup requires few parts, is not very expensive, and is very appropriate for soldering beginners.”

NeoPixel Glass Skull Lighting Effect (A.K.A Mr. BlinkySkull) from Maniacal Labs:

I’ve had this (empty) bottle of Crystal Head vodka for a while. Admittedly I mostly bought it because the bottle was really neat and I wanted to make it light up. Up until this point, I was using a small version of the RGB clock to illuminate it. It was a neat effect, but not very bright. It was time for an upgrade.

I have used before and really like the Arduino Pro Mini. All the Arduino power and flexibility in a cheap, tiny package. I picked up a 16 LED NeoPixel Ring not too long ago, and I really like how neatly the APM fits inside of the ring (held in place with some solid-core wire. I can definitely see using this combination in other projects. For this project, the wiring is pretty basic. The ring power and ground are soldered to extra VCC and Ground pins respectively on the APM, and a barrel jack is soldered to the RAW (voltage regulator input) pin and another extra ground pin. Yet another nice thing about this configuration: the APM has enough extra pins to attach a peripheral and an extra power tap. The ring Data pin is connected to digital pin 7…..

NeoPixel Ring – 16 x WS2812 5050 RGB LED with Integrated Drivers: Round and round and round they go! 16 ultra bright smart LED NeoPixels are arranged in a circle with 1.75″ (44.5mm) outer diameter. The rings are ‘chainable’ – connect the output pin of one to the input pin of another. Use only one microcontroller pin to control as many as you can chain together! Each LED is addressable as the driver chip is inside the LED. Each one has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim. Power the whole thing with 5VDC (4-7V works) and you’re ready to rock. (read more)
