Quick LED Robot Ornament

Crafting under pressure is irresistible. This year the Craftzine gals suggested an ornament swapโ€“ 12 days before Christmas. With a lot on our plates, we all agreed to make time for crafting eight handmade ornaments each, and the deadline made it even more intense. Cheers to speed crafting!

Step 1

Spray paint some scrap cardboard โ€” I chose silver.

Sketch out your robot designs, either in a notebook first or directly on the cardboard.

Laser-Cut ASCII Heart Necklace

This geeky necklace depicts an ASCII heart, like you’d see in email or text messages: <3! The pieces are laser-cut in Sterling silver, then hand soldered to silver tubes that hang from the 20″ curb chain. The necklace has a high-shine finish and is treated to reduce tarnishing. The pendant measures 1.5″ square, and the two pieces dangle freely with a silver bead between them. This necklace makes a great gift for any special occasion, especially Valentine’s Day. Made with love and lasers in NYC – buy now at the Sternlab store as well as Adafruit and Maker Shed. Discontinued!

The 5000W laser cutter that cut these pieces is the size of a living room.

Resistor Necktie

Construct a basic long necktie with stripes to represent your favorite value of resistor – formal wear inspired by the electronics bench.

Gather materials and tools. There are many free tie patterns available online. I like theย Purl Soho print-at-home pattern.

Hacking the Brother KH-930e knitting machine

Limor “Ladyada” Fried and I just finished up an extensive tutorial on hacking the Brother KH-930e knitting machine. We show you how to make your own cable for interfacing with the machine, then how to use it to put custom patterns on the machine without entering them by hand, as I had been doing previously (one excruciating pixel at a time). I made the above tessellating adafruits fabric and the dithering experiment below.

Have questions? Don’t ask them here or send me email, ask in the adafruit forum.

Firefox Necklace

My favorite browser, in 18ga. Sterling silver, video for CRAFT. To get the foxy template, check out Tobi Leingruber’s Foxbling on Thingiverse

I used rubber cement to affix the template to a piece of 18ga. silver sheet, and used a small saw to cut out the shape on top of a jewelry maker’s bench pin, which is that fork-shaped wooden surface you see in the video. Finish it up with files and a lot of sanding using a flex shaft and slotted mandrel. The same flex shaft can be fitted with any number of tools, like the tiny drill bit I used to drill the pendant’s jumpring hole. I got most of the tools and supplies for this project from Rio Grande, who also buys back my scrap metal.
