I thought I could wire the NERF microcontroller board in a day. I started with the screen portion, which needed a hole for the wires to run out. I used a three-millimeter drill bit on the bottom, and it shattered. I could repair it, so I drilled a second hole, but it shattered again. It was not too much trouble to add liquid resin to the cracks and reform them with UV lights. After repairing the structure, I ran wires through it and discovered it was on the wrong side. I gently drilled through the side of the screen holder and passed wires through the correct orientation.
The power supply was the next thing to tackle. I installed a rechargeable cell into the battery holder, but I had to add a wide-head bolt to the coupler to reach the negative battery terminal. Once connected, I attached a voltmeter and adjusted the step-up regulator to 5.0V. I ran a wire from the raw battery connection to an analog input on the microcontroller board. I added wires to the arcade pushbutton and fastened the other ends to the screw terminals. I had to look deeply into the pipe to discern which wires came from the infrared emitter and which belonged to the addressable LED ring. I installed the microcontroller on the platform and powered it up.
The rest of the posts for this project have been arranged by date.
