Laser cut whale with BBC micro:bit micro computer from Jurgen Geitner on Vimeo.
I edited the whale drawing using Inskape, an open-source vector graphics editor which is a good, free alternative to Adobe Illustrator.
Figuring out how to place the micro:bit and battery power supply was quite a challenge. I downloaded micro:bit scale drawings from Kitronik which enabled me to mockup the component layout. Once sorted, I sent the files to The Cuckoo's Nest in Pinelands, Cape Town. (Quirky Name!) They did a great job, both supplying and cutting the plywood. The components fitted into their cutouts perfectly! The two sides of the whale where then glued together using wood spacers. Dowels support the micro:bit.
I'm really pleased with how this project turned out. I'm especially impressed by the micro:bit device and surrounding code / project / tutorial ecosystem. It is an ideal vehicle for teaching youngsters about electronics and code in a fun way.
What to make for next year's card though?!
