Tea Light

thingiverse

Create an easy tea light project with the following instructions: print both top and bottom, add a 3D printed flame top with %1 fill and 3 shells; drill a hole in the flame's bottom for a LED, and securely attach it to the light's top box. Use an Attiny 85 chip programmed with an Arduino UNO or equivalent, powered by a CR2330 flat cell battery (3V, 250mA). To program the chip, visit hlt.media.mit.edu/?p=1706. Search for affordable chips and Arduino Uno online. The sketch used to make the light flicker is included in the instructions. After programming the Attiny, glue the small board into the top case with LED protruding from the pyramid tip. Optionally, add a switch or remove battery when not in use. The bottom plate is easily removable and reattachable. View the flickering light in action at http://youtu.be/-C1LpVAJSZk.
