Hexapod in the press

IEEE Pervasive Computing magazine recently had an article featuring the hexapod..

TechFest 2012

Together with PLANETART and FullFormFreedom invited to show some of the robots at the TechFest 2012 festival in Mumbai, India.

MakerBot Thing-O-Matic

Ok, one could argue that it is cheeting, but before the PrinterPrinter is ready, I thought of taking a shortcut by building a makerbot first. The Thing-O-Matic works right out of the box (and about 200 m3x16 socket screws later):

PrinterPrinter @ Refab session

During Fab6, the international fablab conference, the printerprinter has been presented during a session on ‘refab’ at the fablab Amersfoort. Results of the workshop, presentation slides etc. can be found on the wiki. The workshop resulted in a set of ‘house rules’ for refab in fablabs (but they equally apply to work in whatever lab…

Repstrap using HP840c’s

With the StarLC10 matrix repstrap ending up as pizza plotter, a start has been made building a new 3D machine using only the parts of 3 HP deskjet 840c printers. The printers contain many useful parts, the casing is made almost entirely out of ABS (printing material, hurray!) Especially the sliders come in nice, rectangular…

18-servo walker

New A4 flat-kit design: a 18-servo 6-legged hexapod. It does not walk (yet) but servo control works and the mechanics look good: All parts can be cut from a single A4 sheet of acrylic glass. Other parts include 18 miniature servo’s (selling for 5EUR as TopLine mini-servo ES-05 JR (at Conrad Electronic)) and an ottantotto…

Flatpack Walker with Sensor

As presented for the first time on FAB6, using a Sharp gp2y0a02 sensor the flatpack-walker just got a little bit smarter. As long as the distance sensor is triggered, the robot walks backwards. The code is still pretty simple: [sourcecode language="c"] // avoid obstacles using Sharp G2P sensor on Analog 0 #include <Servo.h> Servo frontservo,backservo;…

Spark Creativity? Don’t get out of the box. Design your own box and think from within!

For years I have dismantled old printers, clocks, radio’s, disk drives, got all the screws out and sorted them in neat little boxes, taking the plastic gears, bearings, etc.. and storing them all separately. This all resulted in a workshop with a large amount of boxes, drawers, cabinets, all filled with a wealth of electronic…

nylon extruder #2

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 been…

Getting a HP7585B plotter to work

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:…
