Sleemanj posted pictures of his simple DIY case from a corflute:
So I wanted to put one of my handy dandy LM2577 DC-DC SEPIC’s in a box with some binding posts. Being of an incredibly cheap-ass nature genetically there is no way I’m shelling out for an actual project box if I can avoid it!
So, I present, Corflute as a simple DIY project enclosure material, all you need is hotglue, and a knife :-)
