I liked the headphone adapter I designed that could fit onto a chassis pipe, so I made a second version that attached to a flat surface. The schematic underwent another round of revisions and may be the final version since everything worked.
I continued converting the X-Shot dart gun by opening the chassis. I chose this step to see the internals and determine if I could route other wires internally. There was a lot more space than the NERF gun I opened, so this time I could route wires inside without interfering with the operation. I added a microswitch to the pump mechanism as my auxiliary button and another to the trigger. I ran the wires to the loading chamber, where I will install the microcontroller.
I mounted hardware to the X-Shot gun. I gave up on the goal of keeping the dart gun functional and hot-glued the emitter to the front. I screwed a small prototyping board in front of the black tube to wrangle wires from the LED ring and infrared emitter. I wanted to model a rail-mountable device that would let me run wires through it, but the battery compartment was in the way.
I wired the battery holder, which turned out to be more work than I anticipated. The deep positive terminals were a challenge to reach because this battery holder had rail mounts integrated into the design. I got both sides wired and added the power wires to the spiral wrap already in place, and then added a voltage regulator that I tried to hide under the microcontroller.
I finished wiring the X-Shot tagger. I added a power line to the pull-up resistors to enable the input buttons to function, but I am even more confident in my schematic. All the external wires were protected with spiral wrap, and I ordered some more wire covering. The hinged pipe still swivels, allowing me to access the programming port.
We watched Can't Hardly Wait, which 90s'd so hard it hurt. So many young actors were in the movie and later went on to play significant roles. Benjamin was promoting his manga-style graphic novel about a high school Model UN that faces off against invading aliens in the 90s.
The rest of the summary posts have been arranged by date.
