David Bliss posted about using a genetic algorithm to create designs for the EggBot using Processing. He says, “Each design is a sine wave with eight different parameters.”
Each time the program is run, an initial population is created with 50 individual designs — each with random values assigned to the eight parameters. You then rate each individual design before evolving the next generation. The algorithm chooses individuals to carry on to the next generations (highly rated designs are more likely to be carried forward, but low rated designs may still be used).
Each of the eggs in the photo above was printed from the same program with waves evolved from random seeds.
Last fall we wrote about NanoBeam, a new super-miniature open source aluminum T-slot profile construction set that was on Kickstarter at the time. While comparable in design to industrial profile systems like 80/20, its cross section of just 5 mm × 5 mm is comparable to a stud on a lego brick.
We recently got our tweezers hands on a ‘beam, and yes, it’s real, yes, it works, and yes, it’s that tiny. And just wait until you see the fasteners.
Four blue LEDs blink in sequence, powered by a CR1220 battery. The board is traditional OSHPark purple, with an ISP header for convenient reprogramming. They’re lighter than they look and quite comfortable.
Thank you, Rick! I know what I’ll be wearing to Maker Faire!
Interacting with EggBot, an art robot that can paint very intricate and precise designs on eggs. EggBot taught students about digital design, computer numerically controlled machines and robotics. This was also a fun way to celebrate National Robotics Week!
My husband made something amazing for the eggers again! He programmed a pattern generator that enables you to create triangle or square-based patterns. The output is an svg file that can be plotted on an egg.
I bought the project to help expose my two grandsons to electronics and learn how to build circuit boards. Dan my 10 year old did one board all by himself just using your instructions. Josh my 14 year old did more than half of the boards and I finished them up because I only have the kids for limited time periods. I am so proud of them. Josh complete understands how the Game Of Life works…I don’t HA! We are planning on adding a instruction board to the bottom of the display so other kids can have fun.
I have a CNC router and built the frame. The boards are screwed onto a piece of 1/4″ plywood which floats in the frame. Not glue in. I machined a loose slot around the inside frame pieces. That way I can take the frame apart and easily change out of a board if necessary. It has been so much fun to build and you have SUPER service.
We thank you so much and would like to build more projects that you may come up with. As soon as I get more time with Dan we are going to build the clock.
He also shared his case design (105 kb dxf). Thank you for sharing your time and skills with your grandkids, and for sharing your pictures and design with the rest of us!
