From Siggraph – balancing 3D printed objects

Balance is a delicate compromise between shape, weight and pose. To give a feel of dynamism, many 3D rendered objects stand in impossibly balanced configurations. As soon as you try and print these, the illusion meets gravity, very often sounding in a small thud. Whilst there are several other laser cut support options available as are stress evaluating and relief algorithms, this is a rather simple polygon based method offering to optimise print designs to make the objects balance.

Open Hardware Summit 2013 badge sneak peek – YouTube

Open Hardware Summit 2013 badge sneak peek – YouTube. – Brilliant vcard inclusion and schedule program (last year and this year) – would be an ideal way to reprogram and make it personalised. The landyard points are also connectors – awesome AND – it runs on a coin cell that allows it 100 page turns or if not excessively used run for the entire length of the conference. Up there with the best of Defcon badges

DIY Pick and Place just getting under way

Long road still to travel, but a DIY Pick and Place attempt here.



It’s not totally fair to say that this project is just getting under way. But the truth is it neither picks nor places so there’s a long road still to travel. But we’re impressed with the demonstrations of what [Daniel Amesberger] has achieved thus far. Using the simplest of CNC mills he’s finished the frame and gantry for the device. You can see some of the parts on the left after going though an anodizing process that leaves them with that slick black finish.

The demo video shows off the device by driving it with a joystick. It’s fast, which gives us hope that this will rival some of the low-end commercial pick and place machines. He’s already been working on the software, which runs on a mini ITX form factor computer. This includes a gerber file interpreter and some computer vision for a visual check on part placement. He hasn’t…
