I love the raspberry pi, you can use them for anything. I’ve just finished up a project that is part of the AstroPi up on the ISS. At home though I’ve used them as Media servers, Data Back ups, Temperature gauges, RetroPi.
I like think of them like lego, if you can think it up, you can normally find a way to build it. Though I’m not sure UE4 would work on one.
You’re probably going to need a mold and plastic pellets to melt down into the mold.
Not many ‘moldable’ plastics that would be good around things that get warm or Hot.
Moldable plastic that gets soft from being dipped in boiling water is easily purchasable on Amazon: http://amzn.to/29XW5NH (InstaMorph)
This is about as moldable as modeling clay; slightly more surface tension so it tends to blobbify a little bit if left on its own.
“drapable” sheets of plastic that can be heated until it droops, and draped over molds, is also available: http://amzn.to/2a8qaL3 (Polycarbonate/Lexan)
This is a bit floppy even when cold, but very tough.
You can heat this with a hair dryer or in the oven. However, it’s really intended to be used on a vacuum former with a heating table and a vacuum pump to get good definition against the mold.
I recommend against Acrylic (Plexiglass) because it’s quite brittle and breaks easily.
Also: I have a number of Pi-2s and still one Pi-1. I use them mostly for robotics. I use the default Raspbian because it’s the least hassle.
(I also ran Arch on one for a while, because I like it, but the custom hardware support for RPi makes it a little more friction)
I would recommend against running anything server-like (where data preservation long term is important) on the RPi, because the storage options of “USB thumb drive” or “micro-SD card” just aren’t that great.
Lol a toy robot. But it’s more of a hobby project anyway, so i would have used to cheap plastic to build a prototype before thinking of investing further.
