An Open-Source Rotational Casting Machine

[Aurelio] wrote in to tell us about the smartCaster, an “Open source automatic roto-casting machine.”  For those of you not familiar with roto-casting, or rotational molding, it’s a process whereby something to be formed is placed into a mold and then melted while spinning.  This item is often plastic, but it can be another material such as plaster of Paris or even chocolate.

Naturally, having something made using this process is generally very expensive and generally requires a high volume of parts to be made. The smartCaster Kickstarter project aims to change this. Although in the prototype stage currently, [Aurelio] claims to need only $1571 to finish his project and make it ready for the prospective at-home rotational molder.

Although it’s a much different tool than we see here most of the time, for the right project (custom Easter Bunnies anyone?) it could be quite useful. Check out a video of the prototype in action after the break.

And if you drive a typical car more than a mile out of your way for each penny you save on the per-gallon price, it doesn't matter how worthless your time is to you--the gas to get you there and back costs more than you save.

What is going on!?!

Guest Lecture #18 – Jason Oberholtzer (I Love Charts)

Today's guest lecture is by Jason Oberholtzer of I Love Charts. ( Jason actually had an alternative guest lecture all ready to go - titled 'The Week The Internet Almost Exploded" ( but decided to update it once he realized what was going to be all over the East Coast this weekend. Jason also has a blog on the Forbes site (, and recently announced an upcoming book for I Love Charts. Thanks, Jason! - - And thus ends guest lecture week - there might be more guest lectures randomly dispersed over the next few months, as I might need a quick substitute as I try to finish up some scientific work - but for now, hopefully you enjoyed different voices and different faces. If the power is still on later, things will be back to lessons as usual on Monday. Catch you then.

Creature feature.
