2020-11-06 (F) Weekly Summary

I began working on the lighted base. My teammate suggested that we use a frame meant to display vinyl album sleeves because they were the size of my acrylic sheets. Happily, the LEDs fit nicely into the frame. My goal with these lights was to test if I could use five-volt signals from a microcontroller to dim a 12V light strip. For now, I am using a stock controller for testing.
Color-changing light frame

 I engraved two acrylic sheets with sample fonts. The first one cut a raster image of a font called Vineta, and the second was a vector font called Symbols. The raster image took twenty minutes to cut, and the vector took five minutes. I could add filigree to the unused areas to give it extra depth, but if we go with an infinity mirror, that would be enough activity.

I converted my boards to PDF before I brought them to the laser cutter, where I cut two more boards with the fonts Monospace and Bauhaus 93. The plate on the right looks faint because I mirrored it and cut the backside, so the front face is smooth.

The team had a group chat, and we decided upon a font, so I removed the protective film and placed it into the lighted frame with a mirror and then a couple of mirrors to create the infinity effect. I like the wispy font because it repeats into the background with crisp edges, whereas a blocky font might look like a blur.

I made a model for a plastic bracket that should hold the mirrors and font sheet in place. The pieces had to be small so that they wouldn't interfere with the lights, and there was no need to make them overly complicated. The slots' thickness was based on measurements, and the spacing between the two planes should correspond with the frame depth.

My next modeling task was a pointing shuttle for the game. We needed magnets on the underside, so I had to create a shape that was instantly recognizable as a Ouija pointer but capable of hiding a couple of disc magnets.
