Our Deluxe LED Menorah kit is an updated take on the traditional hanukkiyah, the nine-armed Hanukkah candelabrum. Two candles are lit on the first night of Hanukkah (one “real” candle plus the lighter candle, or shamash), three on the second night, right up to nine on the eighth night. (That’s (2+9)*(8/2)=44 candles all together, for those of you keeping score.) Ours works pretty much the same way, but uses less wax. When you turn it on, it displays the correct configuration of LED “candles” for a given night of Hanukkah. Each time that you press the button (or switch it off and back on), it displays one more light than it did the previous time that you turned it on (unless it showed all nine last time, in which case it goes back to two). The LEDs are lit up in the traditional sequence, with a gentle fade. This is an open-source project, designed to be hackable. Design files and source code for this project can be found at Evil Mad Scientist Laboratories. Guaranteed to be more kosher than a bacon cheeseburger.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
