Case for Pocket C.H.I.P

I'm a big fan of one of my newest gadgets, the Pocket C.H.I.P. (P CHIP). And I've learned that anything I like needs to have a case, otherwise it's going to get scratched. So, with most things like this I asked my wife to make a case for it. But then I decided that perhaps it was finally time for me to try and make it (with her walking me through it of course).

Making a Replacement Chair Foot

I have recently moved to be close to Michigan Tech. And so far the process has gone great. Except for this chair. It's always been fine on the carpet in our old apartment, but now that we have hardwood floors, it needs to be dealt with. The chair is missing a plastic cap on it's foot, which makes it impossible to apply a scratch-preventative felt pad. Luckily, to a man with a 3D printer, everything needs to be printed.

Creation of a Better Map for my D&D Group

Since I've moved away from my home-town area, my Dungeons and Dragons group is going to have to start meeting online using Roll20. I decided one of the first things to do to prepare for this was to create a more visually appealing world map. I figured this was necessary because A: I wanted to do it. and B: Our group play a lot with theater of the mind, so during world-travel from location to location, I want something cool to put up on the screen. In Roll20, I apply a hex-grid to aid with gauging travel distances per day.

Three Point Bend Test of Various 3D Printed Samples

Every time I print something off on my Printrbot, I ask myself, "Do I really need to use this infill and wall thickness?" And then I decide to just go with my standard settings (40% Rectilinear fill with 3 layer wall thickness) and don't give it anymore thought. But all of that has changed.

PCB Design Workshop

The following pages are a set of content that I have prepared for a workshop that I have instructed at SVSU for 2 sessions. The workshop involves a discussion on The NI Circuit Board Design Suite, as well as a step by step design process for making a power supply circuit board. Then attendants are given a custom measurment circuit design, and are given the opportunity to apply their new skills to design a circuit board during the workshop.
