LED Menorah
A PCB menorah! This is pretty straightforward- an ATTiny85 controls 9 LEDs that are reverse-mounted to shine through the PCB, illuminating the "flames" at the tip of each candle. The LEDs are charlieplexed so that only a few pins on the ATTiny are needed. Component cost is less than $10 (though you'll need an Atmel programmer. I think an Arduino can be used).
I recommend ordering with a blue solder mask, white silkscreen, and lead-free HASL finish. The white area in the body of the menorah is bare metal (candles aside, which are silkscreen). You could also go with a gold finish if you prefer that look, or immersion silver if you want to get fancy.
I found a few mistakes while asembling the boards, so make sure to check out the GitHub repo before ordering parts!
