My family and I were planning to attend a C.O.G.S. (Community Supported Gathering of Steampunks) mini-gaming convention. Two days before I saw an Adafruit episode of Sho & Tell where someone had made a cute cat-themed micro:bit case. I loved it. So I decided to make one for the event -- the logo was a Steampunk Cthulhu-style creature. And so this little guy was born.
I coded it using MakeCode so that the screen made a "chomp chomp" effect. It also reads "COGS <3".
This is the first time I've ever hacked a badge, but I think I'll add a similar cardboard-based project to my Maker Camp this summer.

I started by remixing a micro:bit case by smfox10 on Thingiverse. I used Tinkercad for the design work.
I printed the case pieces and top hat in black PLA on a Rostock V3. The files are available on Thingiverse.
After printing, I sprayed the item with Rustoleum primer for plastics and let it dry well. I then painted with various acrylics. The top hat was finished with metal gears and goggles made from a bit of leather, copper wire and a bit of acetate. It's all held together with Krazy Glue gel. I finished it with a light coat of clear acrylic sealant. I then added a metal bar pin back to the case to make it easy to wear.
I coded the micro:bit using MS MakeCode. Pressing both buttons together made the "chomp chomp" animationon the screen. Pressing the A button sent the string "COGS" and a heart icon. Pressing the B button sent the string, "Hi. My name is Steve. I'm cooler than you." Shaking the badge cleared and screen to conserve battery. The code is available on MakeCode.
