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 beenRead more

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:Read more

Nylon Extruder from soldering station

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

Pizza Plotter

Bringing personal fabrication to your kitchen: the pizza Plotter. During one of the last lectures I gave for Creative Technology about reprap‘s and personal fabrication one of the pizza hungry students (Symplexity) pointed out the necessary connection between pizza and production. Thus the idea for a Pizza Printer was born. The previous posts on theRead more

Repstrap V2

It is fun to see how deprivation of material can spark creativity! By setting the boundaries for this project to use ONLY the parts of printers and computer junk, you can – will come up with solutions you otherwise wouldn’t have thought of! After last week’s enthusiastic post, reality kicked in hard when trying toRead more

Repstrap V2

Some time ago I tried rep-strapping using 5-1/4” diskdrive motors and MDF wood. (see here). The motors turned out to be way too weak, the M5 thread way to slow. Perhaps a larger thread (M12) and some bigger steppermotors can save this evening of work. In this second attempt I have been using only theRead more

Rubber Duck Can Be Useful!

I’m not particularly clumsy. Ehm.. That is to say.. I’m not particularly clumsy when it is not Early In The Morning, when I have consumed to much drinks containing alcohol, when I’m not paying attention or simply when the bathroom floor is slippery. Anyway, I have this cabinet with very sharp edges and corners. VeryRead more

Keltic harp tuning when no key is available

This is probably a very very rare issue that needed a special solution. Anyway. If somebody out there find him or herself in the same situation, read on, remember, and know what to do. If you’re out on a stage, with a folk-band, you have your basic tools, the harp is seriously in need ofRead more
