Invention

Makerbot Talk @ Ignite, Wednesday 14/April

Title says it all. For those so inclined, here’s my very late notice that I’ll be talking about Makerbots, Repraps and Thingiverse this Wednesday 14th in the Science Museum. The event starts at 6:30. Ignite is an event that asks “Enlighten us, but make it quick”. It was started by Bre Pettis and Brady Forrest as a way for local communities to share ideas and raise the “collective IQ”, and is traditionally composed of a little Make contest first, (like “Best Bridge Made of Popsicle Sticks”) followed by a series of five minute talks.

The Makerbot Better Live Mousetrap Challenge

So, last night (being about 26 hours ago I think) I posted a challenge to the Makerbot User’s Group, asking for a live mousetrap that I could print, use, and award €25 for. Team Makerbot blogged it, and threw in a teeshirt if the winner was released under an open license, which just makes it all the more cool! Today, I received 5kg of plastic from Reprapsource.com, so I’m ready to start printing tomorrow.

Microlathe and Accelerating Returns in Rapid Prototyping

Rapid Prototyping is addictive. I knew it would be when I bought the Makerbot, but I didn’t know just how much. Since the moderate success of Dremelfuge, I’ve gone a step further into multi-part, assembled devices, and I’m proud of the result. Microlathe is a Makerbot/Reprap printable Lathe that uses a Dremel for rotary power. I spent a day and a half designing the first draft of it in OpenSCAD, another evening printing the parts, and the minutes I could grab over the last few evenings testing it.

Dremelfuge: It works, and it's Available

Long Overdue Update: I’m very proud to say that, some time back, I updated the Dremelfuge design with better tolerances and a better shape to handle tubes. When I tested it (only once so far) at full speed on a dremel with two tubes full of fruit smoothie, it didn’t eject or break the tubes at all. So there you go, Dremelfuge can now be considered the world’s cheapest midi-ultra-centrifuge, capable of putting about 52,000g on up to six 1.5ml eppendorf tubes.
