Do you get some strange gut feeling whenever you buy a new print head cartridge for your printer at home? Some say that the industry has us customers wrapped into a clever market scheme. ;) At the RepRap web page you can now read about the spin-off project Scratchbuilt Piezo Printhead that aims to design an open source ink-jet print head!
Maybe you have just scanned an object and want to print it on a 3D printer. The model has to be water-tight and most 3D programs don’t have “the right tools” to heal 3D meshes easily. In this tutorial from Shapeways you can learn how to use the open source 3D software Meshlab and the German 3D program netfabb to fix a mesh before 3D printing it. Both software packages work perfectly under Linux OS.
Netduino is an open source electronics platform using the .NET Micro Framework. The board features a 32-bit microcontroller and a rich development environment, making it a perfect solution for engineers and hobbyists alike. Read more about it at makezine.com
We have taken som more images of the early Tin Lisa prototype. You can check them out on our Flickr set.
The guys at AeroQuad.com are making a very cool quad helicopter based on the Arduino open source system.
As it seems now it looks as the world soon will have a free solution for video on the web and the umbillical cord to Flash can be cut fo good. Google has namely opened and released the VP8 codec which makes this possible. Garrett-Glaser, a x264 and ffmpeg developer has taken a deep look into the VP8 decoder and found some room for speed improvement. :) Read more at linuxers.org
Here you can see our member Jan on his first test ride of recumbent bicycle Tin Lisa. It is the first rough prototype of a recumbent design with simplicity in mind and which will be released soon as an Open Source hardware.
It took by the way just a two minutes for Jan (who has never ridden a recumbent) to get the balance and ride without assistance!
