Adventsljusstake (Swedish Advent Candlestick)

This model is a miniature swedish advent candlestick, and is intended to be outfitted with 3mm flickering LED lights. I power mine from a microUSB cable - one of the feet is hollowed out with room for a microUSB breakout board.

The LEDs I use have a forward voltage of 2v, and are wired as four parallel pairs of LEDs in series. In one of the pairs (since the model takes 7 LEDs), a 200ohm resistor takes the place of one LED. A 100ohm resistor sits between the entire circuit and the power source
