I bought a bunch of things as a result of the feedback in the video comments and what people said before that already - basically a whole set for casting stuff in resin. Then I designed a case mould in 123D Design where I would cast the negative silicone mould in. The silicone came out wonderfully, but when I tried to pre-seal the switch and IC socket, the resin got into the parts, meaning I have to resolder them. It also seems as if the ratio wasn't mixed 100% right, as the resin is still very liquid, although it has been poured 3-4 hours ago. If it is not hard tomorrow morning, then I will mix up a new batch and remove the first layer of resin to start over.
