I revised the trigger and front grip to match. The grip features a shroud that covers the trigger's skirt and extends over the keyswitch. The new design is quick to assemble and has a clean look.
I finalized some details with the handle/tagger models and returned my attention to the emitter. I designed it when I did not have a firm grasp of the overall concept. I revised the lens holder to attach to the front of my ABS pipe and hold an LED ring. The model was too large for my printer, but I printed it with the edges clipped.
I gathered the schematic parts I wanted for the tagger. Some of them were not in my library, so I drew them. I mostly stuck to pictorial representations instead of schematic symbols and abstract blocks. I do not like the mixture, but it may help some people with connections since the pin placement is part of the drawing.
I finished the first pass on the tagger schematic, but I should add labels to help identify the components. Some of the parts may be unrecognizable without description.
I modeled an adapter to go between my 30mm scope rings and 3/4" PVC pipes. The outside diameter of the pipes was 26.75 mm, so I offset the pipe to place most of the cushioning at the top and create a sturdy part. I added wings with holes to interface with the scope ring's fastening hardware.
We had seven guests as Sarah organized a show with quiz questions from previous episodes and some about the hosts' cats. The quizzes were fun, and Mr. Fish won the contest, receiving cat stickers as a prize!
The rest of the summary posts have been arranged by date.
