Tim and I released our episode on genetic engineering. This was a subject we both had to study beforehand. Tim was very excited and I think it's highly relevant to biohacking but it's not something I have any familiarity with. In fact, I had to hunt around YouTube just to find a video of people actually performing a basic experiment with a CRISPR kit before I could grasp the idea. Lots of videos talk about what's possible with CRISPR but seeing the process unlocked it for me.
I'm not sure how accurate our information was so I'm hoping someone will comment the true capabilities of CRISPR.

One of the vital pieces for holding a lens was another piece to make a sandwich around the lens. Unfortunately, the simple disc was crowding the nearby components so it had to be revised into a ring with ears. Those ears were in the same position as they were on the disc but sides were hollowed out.

For the prototypes, it was acceptable to have the computer exposed. In fact, it may be important during programming to be able to switch the I/O pins. An adapter was modeled and printed which could mount the Raspberry Pi0 securely. Measurements for the Pi0 were easy to find online and yielded an accurate model.

Two taggers were assembled with parts that had been printed at various stages. The construction was nearly identical but some of the models were slightly different and the filament used didn't always match so the taggers were easy to tell apart. The first construction even had a different looking handle.
Two constructed taggers
Wiring for a single tagger was done. For the first stages of programming, everything was wired to DuPont headers that could be easily placed on the GPIO pins of the Pi0. Each wire was attached to a light or switch by solder or crimping.
Some of the hardware wiring
A handle was modeled so people without access to the handles I've used, or those who didn't want to purchase a tape gun just for the handle, could print one. This handle still used 1/4" (6mm) bolts but it needed two to maintain stability and durability. The complete model, shown below, makes more sense as a rendering now.

The rest of the weekly summaries have been arranged by date.
