Eric over at Low Voltage Labs has posted up his design for a simple PCB ideal for putting an LED into a pumpkin. This is very much like our simple LED pumpkin project but in a neat, reusable format. And it makes a mighty cute little jack-o-lantern all on its own.
He has made it available as a kit with PCB, switch, resistor, battery holder and the same candle flicker LEDs which we love so much. Unfortunately, the kit is currently sold out. Hopefully he’ll make more, if not in time for this Halloween, then at least for next year.
We’re headed to the East Bay Mini Maker Faire this Sunday, October 16th at the Park Day School in Oakland. And we have a discount code for you! Enter EGGBOT to get 15% off tickets purchased online.
We had a great time last year, and are excited to be taking the Eggbot back for more fun. We’re also bringing along the Ostrich Eggbot, which can fit even larger pumpkins. The lineup of makers for the event looks great, and the schedule includes an all-star cast of presenters, lots of workshops, and three music stages. Hope to see you there!

Halloween is one of our favorite holidays, and our collection of Halloween projects continues to grow. Every fall we update it to include our latest projects for the season. In the list that follows, we’ve organized dozens of our Halloween projects into categories: costumes, pumpkins, decor and food.
Awesome little LED Jack-o’-lanterns are quick and easy to build yourself, in the tradition of LED throwies.
Special bonuses: (1) Now with candle-flame flickering LEDs and (2) way brighter than those little LED tea lights! Continue reading →
Here’s an neat idea for a jack-o’-lantern: Hide a single white LED just beneath the thin surface of the pumpkin. And program it with the same slow “breathing” effect that indicates sleep on Mac computers.
The result? A pumpkin that sleeps like a Mac. It’s actually quite striking, in part because the effect becomes invisible every few seconds. It’s also an easy microcontroller project: our demonstration video and build instructions follow. Continue reading →
