EggBot holiday project roundup

It’s close to the holidays, which means people are pulling out their EggBots and getting creative. Last year, we posted a set of holiday designs and some tips for working with ornaments. Here are a few projects we’ve found this year.

Erin Ruppert made this lovely “First Christmas” ornament. The gold ink looks great on the clear ball.

Erin also made ornaments with ornaments on them, which somehow seems fitting.

Lotte made an ornament for her mom at FABKlas, a maker education program.

The folks at FABsterdam made this Mario ornament.

MAKE Ventura used gold Sharpie markers on a matte finish ornament to great effect. Other makerspaces are playing with their EggBots, too. The Johnson County Library in Kansas is doing Eggbot ornament tutorials in their makerspace.

Chris Lynas took the EggBot to “work and school Christmas fair raising money for charity – result: £200 in under four hours!”

Fran marked up eggs for a family igloo making craft party.

Lastly, our friend Miguel engraved glass ornaments with his EggBot.

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.

Evil Mad Scientist Valentines, 2014 Edition

Lo Res Valentines

Last year we released a set of six equation-heavy ”Download and Print” cards for Valentine’s day.  This year, we’re doubling the size of the collection (to twelve!) by adding six more cards, this time heavy in symbols, not equations:

You turn me on” …with an SPST switch.

I can hardly resist you.

There is room for a future superconductivity joke here, involving a phrase like “I can’t resist you (below a certain temperature).

You can download the full set — including the 2013 cards — here, a 500 kB pdf document.

As with last year’s set, print them out on (or otherwise affix to) card stock, and [some steps omitted] enjoy the resulting lifelong romance.

 

Decorating Christmas Ornaments with the Eggbot

Red Eye

Andrew Probert, the designer of the Cylons for the original Battlestar Galactica TV series, wrote to say:

Years later, now, I just was made aware of this great pumpkin idea of yours and wanted to thank you personally for keeping my toaster ’alive’ in a fun new way… this is SO cool.

Our Cylon Jack-O-Lantern project and Larson Scanner kits are carrying on the tradition!
