After getting the frame assembled and tightened for my Prusa Mendel i2 3D printer, I tried to assemble the build platform my the printer. This turned out to be more frustrating than I was expecting, and I actually built the bed in a way that was nearly impossible to level at first. However, after buying […]
This past Friday the Omaha Children’s Museum officially opened up their brand new Makerspace for kids, and invited me to come out and share some of my work. I showed up with a car full of projects from my last year or so of making, including UNK’s Makerbot Replicator, my own Prusa Mendel 3D printer […]
After getting a little bit burned out last week from working on my aquaponics system, I spent the weekend making quite a bit of progress on my Prusa Mendel (i2) 3D printer. I’ve known what the next steps in building the machine where for a while, but just hadn’t gotten around to doing it! I’m […]
Prusa Mendel build update #2: all electronics acquired, miscellaneous hardware, updated sources and BOM
Progress since the last built update was a little slow, because I had to wait to get some money (hooray student loans!). Well, late last week that problem was solved so I went ahead and ordered all the electronics for the printer! This is by far the most expensive part of the project. In fact, […]
While working on the Eyewriter 2.1 open-source eye-tracking system I realized that the most expensive and potentially annoying aspect of the whole system is the optics assembly. To help reduce some of this cost and the number of parts that need to be sourced I experimented with 3D-printing a threaded M12 lens mount.
A 3D-printable, snap-together housing for my openSip+Puff project (an open-source sip-and-puff interface). After iterating through several different designs and parameters I was able to create a strong case that the openSip+Puff circuit board can be easily mounted into, with access holes for the USB cord and vinyl tube.
