Hercules Extruder

21 12 2008

I’m working on fabricating the Hercules extruder for the reprap. It is simpler then the current extruders, and it just looks sturdier and more reliable.  The lasercuts look like this:hercules_extruder

Haven’t tried these out yet. Here is the sketchup file

Superconducting Cable

21 12 2008

On Dec 4th 2008, I ordered 20 meters of 4mm YBCO superconducting cable from theva. The lead time is 8 weeks, so it hopefully will arrive at the end of January 2009. This should be more than enough cable to complete several basic tests of superconductor construction. I also want to explore the fabrication of a SMES device for high power, high speed lab power supply. We will need to devise circuits to charge and discharge the superconducting cable, I’m not seeing much information on this topic on the internets.  And of course this will require liquid nitrogen. I’ve always wanted to play with liquid nitrogen.
