Erin posted on the Make blog about large scale CNC projects at Fab Academy, including a CNC workstation cart based on our design made by Lina Monaco. Lina goes into more details in her post here.
To design it I started from the Evil Mad Scientist’s CNC Workstation Cart redrawing to adapted it to our necessity as an horizontal PC, cables space inside, and last but not least without any screw or glue.
She posts about her design process, including prototyping using a laser cutter to make a scale model. It looks great—we especially like the cutout drawer handle design.
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.
