    Real Laser Arm Cannon From Metroid!

    Again I say thanks to Hyper_Ion for a very enjoyable andchallenging project. It should benoted that this build will require more time, material, and labor than you might initiallyperceive. I built the Blasterinitially with the laser installed, to satisfy my adventurous side; however I have now defanged it and added additional Neopixel rings, circuit, and code to simulate thelaser blast. It is more fun to be able to pass around forothers to "try" without worrying about it being loaded. It is every Maker'sresponsibility to build, operate, and demonstrate his projects wisely.I made a few design changesalong the way:1.All the cavities for arm and ring Neopixelstrips were filled with casting resin.

It is more fun to be able to pass around forothers to "try" without worrying about it being loaded. It is every Maker'sresponsibility to build, operate, and demonstrate his projects wisely.I made a few design changesalong the way:1.All the cavities for arm and ring Neopixelstrips were filled with casting resin. Firstmake sure that everything is functional because the casting will preclude anylater repairs to strips.2.The upper arm assembly was lined with automotiveheadliner fabric. Although it servesseveral purposes, it is primarily cosmetic.3.The Nano assembly was built using a socket. I have been in the electronics field formore than 50 years but I still manage to occasionally "let the magic smoke out". Repairs will be much faster andeasier. You will also gain mountingarea by putting components beneath the Nano. I also located the triggerswitch directly to the end of the PCB.4.I purchased a nested Neo Ring set and used 4 of the 6 pieces. These were mounted to an FR-4 blank circleand mounted in the barrel.5.A domed plastic cap from a scrap solar light wascut down and mounted as a barrel cap.6.Due to the power requirements from 131 Neopixels, a buck converter was installed with thebattery to supply the 5 volts, externalto the Nano.7.Code was modified to account for wiringchanges, Nano pin reassignments, and my additions. This is my weak area, but I learned a lot.again, my thanks. DanE 12/18
