Makers Jack and Steph, of Jack and Steph’s Workshop, have give you a tiny little circuit with which to have a good time Hanukkah in digital fashion: an eight-bit shift-register menorah.
“Whereas it is true that we do not do a lot worship right here at Jack and Steph’s Workshop, we do love celebrations,” the pair write of the LED-adorned gadget. “This sparkly wearable pin is mainly a single byte of menorah reminiscence, designed that will help you bear in mind/train the hanukkiah customs!”

The Hanukkah menorah, or hanukkiah, is the enduring nine-branched candle holder designed to have a good time the eight nights of Hanukkah: every of the eight candles is lit from a central shamash (“helper”) candle, with yet one more lit every night time of the vacation till each candle is burning. Jack and Steph’s tackle the idea, although, swaps bare flames for LEDs — and makes use of a shift register to regulate them.
“The primary press of the button powers on the circuit and lights the shamash candle solely,” the pair clarify. “Custom states that you just now say the blessings earlier than lighting the subsequent candles. The pin helpfully reminds you to say these blessings by introducing a delay of some seconds between the lighting of the shamash and when the circuit permits the subsequent candle to be lit.
“The subsequent button press lights the candle for the primary night time, which is the leftmost candle. Every subsequent press lights one other candle within the right order from left to proper. All of the candles will be extinguished by urgent and holding the button for a couple of seconds.”
The board avoids using a microcontroller by tying the clock enter of a shift register into the button on the entrance. (📷: Jack and Steph’s Workshop)
Behind the 9 LEDs is a shift register which is tied to the front-facing button: a click on of the button pulls the clock line to floor, including a excessive bit into the register to shift the variety of candles that are lit one by one — permitting for full management with out involving a microcontroller.
The menorah is now accessible to order on the Jack and Steph’s Workshop Tindie retailer for $15 as a soldering equipment or $20 fully-assembled.
