High-tech ornaments and Menorah for the Holidays

While these projects are probably a bit beyond my soldering skills, I present them here for the uber-geeks in the group.

The first is a signle-character ornament that spells out holiday messages and the second is a LED Menorah that automatically lights up the correct number of lights for each evenings celebration.

Happy Holidays!

How to make high-tech LED decorations for the holidays

Here we present two open-source, do-it-yourself, microcontroller-powered holiday electronics projects: A micro-readerboard Christmas tree ornament and a mini-LED Hanukkah menorah. Read on to see exactly what they do, how they work, and how you can make your own.


Our mini-LED Hanukkah menorah is a modern update of the traditional hanukkiyah, the nine-armed Hanukkah candelabrum.

Two candles are lit on the first night of Hanukkah (one "real" candle plus the uppity lighter candle, or shamash which apparently doesn't count), three on the second night, right up to nine on the eighth night. That's (2+9)*(8/2)=44 candles all together, for those of you keeping score.
