Solderless Flickery Flame

We’ve talked previously about making simple LED pumpkins with candle flicker LEDs. Lately we’ve been playing with making better looking flames by using multiple independent flickering LEDs with different colors and lens styles. It makes a spectacular difference: it goes from something that looks like, well, a flickering LED to something that really looks like there might be a flame in there.

The end result is pretty neat: A compact battery powered “flameless flame” that looks great in a pumpkin, luminaria, or as a stage prop. The interplay of the different LED types and colors gives an ever-changing and shifting flame display.

Other than the candle flickering LEDs, the parts are commonly available. We’ve also bundled them together in the Solderless Flickery Flame Kit.

Components:

  • Battery Holder (2×AA with switch)
  • Mini-breadboard
  • 6 × candle flicker LEDs (2 red diffused, 2 yellow diffused, and 2 yellow clear lens)
  • 6 × 68 ohm resistor
  • 2 × wire jumper
  • White paper bag (optional)

Also needed:

  • 2 × AA Batteries (not optional)
  • Wire clippers, cutting pliers, or “beater” scissors (optional)

Hook up the battery holder to the breadboard several rows apart to give enough room to install the resistors and LEDs. Optional: peel off the backing on breadboard and adhere it to the battery holder. Connect each LED with its own 68 ohm resistor. (Use the “in parallel” method from this article.) The extra jumpers are included to help bridge across the center gap in the breadboard.

Trimming the resistor leads will keep the breadboard tidy, and help prevent short circuits. Trimming the LED leads to varying heights will help distribute the light in different ways.

The white paper bag included with the kit can be used for creating a traditional luminaria or for making a ghostly halloween decoration.

Lady Ada Lovelace Day 2014

For Lady Ada Lovelace Day, we would like to celebrate some of the women working in science, technology, engineering, art and mathematics that we got to meet and spend time with at Maker Faire New York this year.

Our friend AnnMarie Thomas had just released her book Making Makers, and was speaking several times during the faire, including hosting the Making Makers panel I participated in, as well as assisting her daughters, Sage and Grace, in presenting a Squishy Circuits workshop.

Also on the Making Makers panel was Sophi Kravitz, who was showing her WobbleWorld virtual reality experience.

Dyeing
Patricia Miranda of Alchemical Tech was there again this year teaching dye-making. I reluctantly declined her offer to get my hands dirty.

Jenine Bressner, who has been sharing her glassworking and laser textile projects at Maker Faire for years, was there as an attendee, finally getting a well-deserved chance to see the faire.

astronomical quilting
Emily Fischer of Haptic Lab was displaying her beautiful astronomical quilts.

NYSci costume making workshop Peggy Monahan of NYSci was helping run a costume design workshop with low cost, easy to use materials like plastic tablecloths, butcher paper and snow-cone cups. Many people bedecked with dinosaur spikes and other fanciful accessories could be seen roaming the faire.

Othermill Representing Othermachine and demonstrating the Othermill was their project and support engineer, our friend Simone Davalos.

Fellow electronics shop owner and friend Cheryl Hrynkiw of Solarbotics was demonstrating their projects, like the solar marble machine.

Rachel Meyer, Selena Ahmed, and Ashley Duval of Shoots & Roots Bitters are three scientists who care about culturally important plants, and bring their stories to people through their uniquely blended bitters.

Sharon Shattuck of Eavesmade was selling laser cut and engraved coasters and ornaments of scientists. You can find her sets of women heroes of science coasters and ornaments in her etsy shop.

Toward the end of the faire, we ran into Limor Fried of Adafruit. It was great to catch up with her and hear about the great strides her electronics business has been making.

There were many more women there showing amazing projects. If I left out someone you want to celebrate, please feel free to share about them in the comments.

    


Evil Mad Scientist Halloween Projects

EMSL Halloween Roundup

Halloween, always one of our favorite holidays, is fast approaching again. We’ve updated our Halloween Projects Archive as we do every year to ensure that all of our Halloween projects are gathered together in one convenient location. We’ll continue to add projects as we post them. If one of our projects inspires you to make something, we’d love to hear about it!
