It’s springtime, the season when eggs traditionally get their moment of glory. In the Egg Contest we want to see what happens when you scramble up your creativity with this theme. Any and all entries highlighting or featuring eggs (or egg-like creations) are eligible.
Jiri Zemanek from Prague sent in this fabulous video of eggs decorated using the EggBot, some with markers, and some with the Electro-Kistka.
Various patterns are generated in Matlab using mathematical equations similar to ones describing Spirograph (or harmonograph) and Phyllotaxis. The patterns are calculated in such a way that when rotated under a stroboscopic light of suitable frequency or when recorded by a camera, they start to animate. It is kind of zoetrope— early device for animation. … Eggs are rotated at a constant speed, special for each pattern, by a brushless motor. No computer graphics tricks are used in the video.
HackerBoxes are a monthly kit subscription for a box of electronics to learn from and hack on. This month, they included our Three Fives board as part of a 555 timer themed box. They post a monthly set of instructions over at instructables, which contain projects you can do even if you’re not a subscriber.
Ken Shirriff has posted a teardown of the beloved 555 timer IC. He sawed the top of a metal can packaged 555 to expose the die underneath.
On top of the silicon, a thin layer of metal connects different parts of the chip. … Under the metal, a thin, glassy silicon dioxide layer provides insulation between the metal and the silicon, except where contact holes in the silicon dioxide allow the metal to connect to the silicon. At the edge of the chip, thin wires connect the metal pads to the chip’s external pins.
He goes on to explain how it works and its cultural significance. He even mentions our discrete 555 and 555 footstool in the footnotes.
I’m pleased to announce that I’m on the judging panel for the new Adafruit Drone Film Fest, the Adafruit Dronies 2016.
The Adafruit Dronies celebrates videos taken from drones. The contest is open to everyone in the United States to show and share their amazing drone videos. You’ll be judged on creative use of technology, storytelling, and cinematography.
Entries are limited to five minutes and winners receive trophies as well as gift certificates to the Adafruit store. The lineup of judges is amazing, and we’re looking forward to seeing your entries!
For 2016, we focus on the technical side of creating art – the physical transition from raw color to applied color on a canvas. We challenge the participants to create artwork to showcase their robot’s abilities.
The team registration deadline is March 1st, and the competition is open to high school and college student teams. Artwork must be uploaded by April 15. (This sounds like a perfect challenge for schools that have a WaterColorBot.)
Public participation in the first round of judging is encouraged, and then the works will be judged by professional art critics on originality, aesthetics, painting capability, and technical contribution (e.g. sharing source code.)
We love art robots, so we’ll look forward to seeing the results of this competition.
