Shapeoko Control Box

May 8th, 2015

Shapeoko Controls

Slowly been putting a Shapeoko 2 together. One of my issues was what kind of enclosure to house all of the electronics and controls. I settled on using an electrical junction box. And yes, my CNC goes to 11.

Key Switch from SparkFun

I’m excited to use these key switches in some robots. Only the key master can activate the bot.

Just Got Myself a Vacuum Former

First Tests

Just got a little vacuum former, typically used by dentists and orthodontists. It kind of looks like an espresso maker, but it does a really nice job. Love new tools.

Experiment with Turned Aluminum and Powder Coating

Turned Aluminum, Then Powder Coated, Then Turned Again

A quick experiment. I turned some aluminum on the metal lathe, then powder coated it orange, then turned just some of it again. The edges look really crisp.

Things on Pedestal

Amazing how if you literally put something up on a pedestal, it makes that something a little more special.

Robot Rabbit Skeleton

Outside and Inside

Been working on a ridiculously involved internal structure for a robot toy. CNC’d aluminum, custom circuit board, off the shelf hardware — all to be covered up by some tin cans.

As I mentioned before, I’m proud of the 9 Volt battery holder solution. And yes, those are Knight Rider eyes.

Robot Neck How To

I mentioned before that a slip ring and a caster swivel make for a great robot neck. Here is a video with more details. Thanks Jeff.

9 Volt Battery Holder

9 Volt battery in place

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.

Layers stacked up

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.
