MAKE Magazine ran a how-to on some Thanksgiving themed Robot Recipes, Pumpkin Pi Bots. Made from the cans of pumpkin pie ingredients.
Some parts are straight forward and some parts are so overly complicated, I’d recommend skipping them altogether. But it gave me a chance to use my new Othermill and slip roll. Happy Thanksgiving.
Finally finished up some CNC’d toy cars for some nephews. 2.5D cut plywood with some off the shelf wheel assemblies and a couple of coats of shellac. These might look pretty good cut out of walnut.
This may not be Kosher with the Lego purists out there, but I milled up a Lego brick with studs on both surfaces. Basically, it has two male ends instead of the traditional one male, one female.
Side note, I used old floorboards as the stock material (maple I think). This may be the perfect material for small desktop CNCs. Flat, milled hard wood that is essentially free. Just watch out for nails.
Milled a quick wooden Lego experiment. I can’t believe it fit the first try. Heavily influenced by Notcot.
More to come.
Sanded and assembled. All it needs now is some paint.
Pretty beefy wheels and axles for some toy cars. Everything to make these are off the shelf.

I’ve been playing with different ideas for wheels recently (more on that soon), and so I obviously needed some toy cars to attach them to. Here are some of the first passes. 2D CNC’d plywood pieces glued together. Needs sanding, finshing, and wheels obviously.
I have yet to find a decent 9 Volt battery holder. So I’ve just designed it into the internal structure of my latest robot.
A bunch of CNC’d aluminum plates held together by standoffs. The battery sits in a cutout and a set screw holds it in place from the bottom. More to come.
Made every kid in the family a robot rabbit this Christmas. Each kid got their favorite color. Each one sized according to age.
Lately, I’ve been making a lot of robot chest plates and bottom plates. I’ve been experimenting with modifying steel electrical plates, technically called universal crossbars. Machining, bending, and modifying them. Typically, I get mine from Grand Brass (and this one).
So far, I like the results.
