Dude my first one, the original floating one I did back in like 2008 was craft foam, thumb tacks, bic pen ends, chapstick caps, and the lids to those little bottles of bubbles they hand out at weddings to blow at the bride and groom instead of throwing rice. LOLUmm... Thanks? Honestly, my goal is to make something that's instantly identifiable as a training remote, even if it's not 100% accurate. That, and I'm trying to keep the build as cheap as possible, so that rules out ordering things online (not that I would do that anyway), kits, and cast or 3-D printed parts.
