SBE is pleased to offer a new, updated Hanukkiah for 2021 / 5782!
This menorah, which I am calling the Model III, is an updated version of the Model II. It includes a built-in stand made of printed circuit board, like the rest of the menorah. It also has an improved battery holder and I think a better aesthetic because of the location of the buttons. Otherwise, it is very similar to the older Model II.
This year's model also adds a few new "trick" modes that are not in the older menorahs, including binary counter demo and "sparkle mode".
The Model III
7 1/16 " (W) x 4 1/8" (H) x 5/8" (D) (appx.)
Put 2 AAA batteries in the battery holder on the back.
Turn the hanukiah on by pressing the “on” button.
At first, only the shamash is lit
Advance to the next night by pressing the “night” button for a moment (less than a second).
Advance to a different mode or effect by pressing the “night” button for about two seconds, but less than four seconds.
Turn the menorah off by pressing and holding the “night” button for four seconds. (It also turns off on its own after 20 minutes unless you adjust that setting -- see below)
Sure, a simple menorah is fun, but why keep it simple? We added several fun “trick modes” to this menorah to entertain you and brighten the holiday.
When you turn the menorah on at first, it will be in a default “menorah mode” with a flickering candle simulation. Other modes include a menorah mode with without flickering and a few fun “chaser” modes that honestly have nothing to do with Hanukkah, but when you've got a microcontroller and some LEDS how can you not, amirite?
There is also a mode for adjusting the time the menorah stays on before turning itself off.
All the modes, and how to switch between them are described in the Owner's Manual
This Hanukiah consists of electronic components soldered onto printed circuit board. It's perfectly safe to handle, but the menorah should not be used where a small child might put it in his or her mouth. (Also, it's gonna be yucky you’re likely to break it that way.)
Also, one of the fun trick modes of this menorah, the “secret message” mode involves swinging the menorah around in the dark. Be careful not to hit anyone! We’re not responsible for broken noses!
A pair of AAA batteries should power this hanukiah for eight days with no problem. In fact, they might even last eight years -- a miracle! However, just to protect your menorah, we recommend you remove the batteries between Hanukkahs in order to avoid the ickines of battery leaks.
Want to hack this menorah? Learn about microcontrollers? Make it do something weird and fun? Have at it!
In order to reprogram the menorah, you will need a device programmer, like this one, and you'll probably want to solder on a programming header, like this one. You can use another AVR programmer, but the Sparkfun model linked can provide 5V power, which is very convenient, since the 3V from the batteries are not sufficient for programming. You can use the Arduino IDE to write and compile your program, but you will need to install the AttinyCore package (which you can install from inside the IDE) to build code for the process on the hanukiah.
If you "brick" your menorah, I may be able to get you back in business, so contact me for help.
