I’ve had some time to work on my CNC milling and made a Cribbage board for my Dad for Father’s Day. (Yes, I’m late.) We just made it back from a safe, socially distant family vacation in New Hampshire, a place my family has visited for about 4 generations. One of our family traditions is to play Cribbage and we introduced it to my brother-in-law and my nephew. I think they enjoyed it, but you can never really tell because, well, families are not really supposed to share their opinions with one another, right? At least my nephew shared his opinion: it’s boring. Apparently the only thing that isn’t boring to this 15-year-old is a game on his phone where you endlessly “collect power ups to get to the next level”.

Making COVID stay away
Do a web search on 3D printing and COVID, and you’ll find endless examples of the 3D printing industry (both commercial and hobbyist) mobilizing to create personal protective equipment (PPE) in response to the severe shortages that many countries face. If you have any experience with 3D printing, helping out is as simple as downloading the design files (such as this one for face masks or this one for face shields), sending them to the printer, and waiting 3+ hours for the printer to do its job.(*)
So when Tim of Adirondack oral and maxillofacial surgery contacted Zak Robinson, my colleague over in the Physics department, and lamented his inability to secure PPE for his staff, Zak and I got to work. Both of us use 3D printing in our teaching and research activities at SUNY Brockport, and when the pandemic shut down the campus for the remainder of the semester, we each brought home our printers so we could carry on with our making.

It sounds like the CDC is going to recommend that everyone wear face masks to help fight spread of the coronavirus. Now, since the government is incapable of handling the most rudimentary of supply chain issues (probably because a few senior officials refused to recognize the thread), we are supposed to make our own. Fortunately, we can. Rozenn and I made some for the droids too. No one knows how the virus affects droids, so best to be on the safe side.
#Make ready for COVID
There’s a lot of buzz on the interweb about 3D-printing personal protective equipment (PPE) in light of the severe shortages across the country and especially close by to me. (I’m sure it has nothing to do with sending much of our supply to china last month.) I wanted to see how easy it was to actually do.
I’ve got my 3D printer, a Prusa MK2, up-and-running in my home office. I followed these instructions for making a mask and this design for the face shield. Both designs are reported to be printable without the use of supports or other fancy settings, so I loaded them on the build plate and off I went. After 5 hours of printing (3 for the mask, 2 for the shield) I ended up with this.
I’m surprised at how well these designs printed with no modifications needed. I’ve got some temperature calibration to tweak because both designs have overhangs that printed poorly but only affected the aesthetics of the final object. Double sided tape worked just fine to keep the document transparency in place. I’m now ready to fight the coronavirus … or clean the litter box.
New Year’s project
I received some servo motors for Christmas, so naturally I need to start working on a robot. Details to come on the project, but for now I’ve been trying to figure out how to (a) control two servos with an ATTiny85 microcontroller and (b) talk to that microcontroller with an Arduino that is telling the ATTiny85 how to position the servos.
It took the better part of several days (including some learning and additional trips down rabbit holes, but here we go.
