ledmenorah
Thanks to MAKE for the tip about this open source LED menorah kit from EvilMadScientist.com. This looks easy and reasonably impressive, although I’m not sure whether the current would flow perceptibly in either a Shammai (oldest to newest “candle”) OR a Hillel (newest to oldest) direction. Engineers, you check it out and let us know. I’ll get my soldering kit ready to go.
