Fresh hacks every day
Mcor Technologies recently launched a brand new rapid prototyping machine. The Mcor Matrix forgoes the standard of expensive and rare build materials by using A4 office paper. The machine selectively deposits glue on the sheet of paper: more glue on the cross-section, less on the waste. It then uses a blade to cut out the part profile. The vertical resolution is determined by the paper thickness. … [Read more...]
The RepRap is a self-copying 3D printer. The project has published plans for creating a lasercut acrylic version of the device. They call it a RepStrap since once assembled it could produce printed plastic versions of the machine components, bootstrapping true RepRaps. The plans are available for Ponoko an on-demand product service, and it would cost ~$380 if you used their service. The plans are … [Read more...]

He doesn't talk about how much brightness was lost, but there had to be some. The final … [Read more...]
Today at The Last HOPE, [Far McKon] from Philadelphia's Hacktory presented on community fabrication. Over the last few years we've seen a lot of different accessible rapid prototyping machines created. There's the RepRap, a fabrication machine that has achieved self replication; our friends at Metalab have gotten their own version of the machine running too. The Hacktory has recently acquired a … [Read more...]
[Christopher Jette] did a amazing job converting a 56" rear projection television into a multitouch display. His original inspiration came from this drafting table project. The screen is a large sheet of 1/2" acrylic with a screen material attached to the back side. The screen edge is surrounded by 168 IR LEDs. When a finger tip touches the surface it scatters the LEDs' IR light. A webcam sees … [Read more...]
