Hanukkah is fun! It's the festival of lights. Sure, there was oil that lasted eight days. But how would the story of Hanukkah have gone down if the Israelites had LEDs? Today, that story can be told...
What is it?
This is a PCB Hanukkah menorah that uses LEDs instead of candles. I designed it last year for friends and family. Folks liked it and suggested that it was cool enough to try to sell, so here we are.
The design is total simplicity. The LEDs are driven by two 8-bit shift registers, except for the shamash LEDs, which are driven directly by the processor. The processor is an Atmel Attiny84A. Power comes from two AAA batteries (that you supply).
Why did I make it?
For fun! (And to practice SMD soldering!)
Why is it special?
What makes this menorah a little bit special is that in addition to doing the normal menorah stuff of showing lights for each night of Hanukkah, this one also has some special "trick" modes such as a Knight Rider reminiscent "scanner mode" -- and a few more.
Furthermore, these are powered by a microcontroller and there's a debug header, so they are fully hackable!
If you like, I can send you this menorah as a kit. It is a great way to practice your SMT soldering skills. The microcontroller will be soldered on already, along with a few other components I need in order to program the controller. But everything else will be for you to solder: LEDs, resistors, capacitors, a button. The LEDs are 0805 but the other parts are 0603 so definitely be sure you're willing to try SMT soldering before ordering this kit!
The other menorah
This is the larger of two near-twin products. The other one works the same, but is a bit smaller: Electronic Hanukiah Model I
