I haven't found much hobby machining content on lemmy yet, so I'm just subbing anything relevant to see which one takes off. Guessing that @postal is not TOT but just claiming a potentially popular name. Doesn't seem to have made much effort to populate the community.
I'd be happy to discover other, similar content. I know there's BlondiHacks & Clickspring. Cà Lem does kind of similar stuff, but infrequent and unvoiced. I'd be happy to see people's little projects, but I don't have one to share, myself.
