2020-12-25 (F) Weekly Summary

I kept track of the issues with my laser cut sheets. The first issue is that only the top has holes. I planned to make a 3D printed corner brace. It might have been smarter to put holes in all the corners. The square hole for the voltage display was too large, and the socket for a headphone was not going to work because the plastic was too thick.

I needed some corner brackets to hold my plastic sheets together. Only my top piece of acrylic had a hole, so I designed them to envelope the corners of two plastic sheets and a bolt hole for the top. I'll install four of these brackets at each corner, and only bolts should hold everything together securely.

Slicer software

I wrote out my IO list, which was shorter than I thought, and from there, I sketched a schematic. Many of the components are supportive, like the incoming power. I forgot to add the fuse, voltage display, amplifier, and speaker terminals. All the output from this device will be in the form of the screen display and sound.

I needed some simple feet for the project. I probably could have found some at the hardware store, but I decided to make one with precise measurements. The model is straightforward, with a flat base to rest on the work surface and a recessed area for a bolt head.

Holograms are a neat bauble, but they don't have a lot of practical uses. Nevertheless, their creation is fascinating, and their properties are unique. You can cut a hologram in half, and it will retain the whole image. Weird. Justin Atkin made a few, and some had multiple colors instead of the typical monochromatic type.

A former Hackaday writer built this lightsaber, and it's the closest thing I've seen to the real deal. It's crazy hot, so it cuts through anything susceptible to 4000°F temperatures. That includes a 1/4" (6mm) steel plate.
