After the promising results with the first nylon extruder, we (woutzweers and I) made a new nozzle following reprap extruder size (so a 3.5 mm feed hole and a 0.5 mm extrusion hole). The extruder head consist of a small piece of brass with two holes placed at 45degree angle. The soldering iron has beenRead more
I recently got an abandoned HP7585B plotter. Probably over 30 years old. However, perhaps fast and accurate enough to do some serious fabrication? Why not add a cutter wheel and cut foil, or fabric? Anyway, first hurdle to take is to get the think working. Searching for drivers on internet resulted in two options: 1:Read more
Of course, the machine described in the previous post was never meant to have a sole purpose of pizza printing (which it admittedly does badly) but to become a repstrap machine so I can build a sweet Mendel. Next step after a cartesian robot is the plastic extruder. Although other people have tried to useRead more
http://www.protospace.nl/content/protospace-novu-editie-nl-rtl4 -> see the flatpack walker in action on dutch television – it has also been submitted in the unlimited design contest http://unlimiteddesign.nl/en/node/44/6 It is being used in the fablabtruck: http://www.fablabtruck.nl/nl/fablabtruck/lesprogramma.html Also on idealize (read interview) http://www.idealize.nl/2009/09/udc-2009-edwin-over-simplewalker/ Joris van Tubergen (protospace) talks about the robot in this interview (see vimeo)Read more
Okay.. by common consent my simpleWalker has been dubbed flatpack walker according to hack a day. Who am I to disagree.. It got posted on hack-a-day after my first-time-ever ‘instructable‘ I posted on this topic.Read more
At the protospace fablab I made a laser-cut wood version of the simpleWalker. It took only 5 minutes on the laser cutter, instead of an hour behind the bandsaw! I used 4mm birch plywood. The robot works well (and smells like a campfire … oh well…) Again, it can be seen walking on YouTube (butRead more
This is a try-out of a FabLab-ready kit design for a 2-Servo walking robot. The design is inspired by the lynxmotion kits and the designs by david buckley. The goal for this project is to make all mechanical parts for the servo walker out of 1 A4 size sheet of plywood (or perspex, lexan, delrin,Read more
I’m really enthusiastic about the reprap project. The whole Idea of having a printer that can print functioning parts, just on your desktop is .. well.. cool. The reprap is a machine that can replicate part of its own parts. However, to build one from scratch you get a certain ‘bootstrap’ problem.. Hence you haveRead more
