Robot Rabbit Skeleton

April 16th, 2015

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.

Two Candlestick Projects

April 12th, 2015

Here are two Candlestick projects I’ve been working on.



One I call the Candle Scope, made of turned aluminum, steel, and glass. The candle flame is projected on to a nearby wall. It can be blurred or in focus.



The other I call Glow in the Spark, a turned walnut tea light holder with glow in the dark plastic inserts. The candlelight “charges” the plastic and they glow after the candle has been snuffed.

Had my students turn foosball players on the lathe and couldn’t resist making some of my own.

Milled Delrin Parts with Hardware

I’ve been working on some small fussy parts made out of Delrin and steel. It’s been fun to be so exacting with them.
