Menorah with LED "candles" that are lit using a shamash (helper candle)

The first build (rev A) is working just in time for the end of Hanukkah. The LEDs light when the shamash magnet is brought near the reed switches. I reworked it a bit to add one diode because the 0.5F supercap keeps the shamash lit for more than 20 minutes when power is turned off. The diode drains the charge quickly when the power switch is turned off, but allows the shamash LED to stay on for a long time when it is pulled out to light the other LED candles.
