I'm a MAKER - March 16, 2010

See me at Maker Faire!

I got accepted to be a Maker at San Francisco’s Maker Faire, which takes place May 22nd and 23rd!!!

I’m extremely excited, because it’s basically the equivalent of a science fair for adults, so I get to act out all my geekiness with other geeks in one place. Granted, some of those geeks might be using flame throwers and tesla coils, I’ll be almost as cool.

I’ll be teaching people how to construct and use a rotational casting machine. This machine is very useful, as it allows people to cast hollow objects – which means you can make more things with less material. Also, they are light weight and hollow, so you can turn them into lights and other cool stuff.

I created an Instructable for how to make one almost two years ago, and I received an enormous amount of emails about it, so not I’m taking it up a notch and doing real-time demonstrations. I’m thinking about making hollow chocolate things…maybe unicorns, we’ll see!

So, come see me at the Maker Faire!!!

About to build this awesome machine.

I do have another question though. Where does the heat go in an inclosed rotocast mold? And how much do you pour in? a 3rd? Depending on how thick the walls should be ofc, but some kind o figure would help.

Hi Manfred,

I use chemicals that have there own endothermic reaction - so no heat is necessary.

I'm not sure what your mold looks like or how big it is, but I would experiment to see what the optimal amount of material is. A third sounds like it might be too much, I think maybe a 1/4 or 1/5 is more reasonable.

That's awesome! I'll be at the Faire this year, so I'll definitely have to stop by and check it out. Congrats!
