One of my biohacker friends, Miana, wrote a glow-in-the-dark scarification technique. I loved it enough to get my own, so my wife and I each have a π symbol on our arms in honor of our wedding on 03-14.
I continued my fight with the binding threads. The first step was to create a cutaway view in OpenSCAD to determine where the threads intersected, but they were not mismatched. I took the sharp edge off some of them, but the next print still had binding issues.
I spent ANOTHER day fussing with the threads. I conceived a way to mount everything with nuts and bolts, but I had an epiphany and changed the diameters to allow for resin swelling. I added a hexagonal standoff to the lens holder to keep it off the printer platen. The combination made for threads that bound up less. I will change them again and try better resin.
I gathered the parts and assembled a carbine-length tagger. I standardized on M3 nuts and bolts, but I still had to make several different-sized holes for the handle and pushbutton. I was delighted to have a unit that adequately shows how a finished tagger could look.
I bought some small prototyping PCBs to make infrared receivers and designed a footprint and dome based on their hole dimensions. The dome required clear plastic, which needed infrared-pass testing.
Sarah invited Laurie Calcaterra to promote her latest installment of Path of the Pale Rider, a zombie comic and we discussed 28 Years Later. They both enjoyed the film, but I had more negative things to say.
The rest of the summary posts have been arranged by date.
