Reject modernity, return to analog

Let's talk retro tech, or anything of the sort! What projects or hobbies are you currently working on? Are you leaning towards a crisp hi-fi sound for your turn-table (yo), or just browsing eBay for old broken tech you know you don't need? Is this submission just a cry for help, because I've found myself browsing old Bose Wave systems from days gone by?

I have a box full of old Gameboy motherboards I need to do something with (the current plan is to gift my close friends their own modded Gameboy, because seriously why can't I hold all these Gameboy motherboards). Then there's my AIWA Walkman that needs a new belt, but I've never cracked one of those open before, so we'll see. Then there's this Gameboy Camera mod that is keeping me up at night.

What about you fine folks? I thought about posting this to ~tech, but I thought ~hobbies was just as relevant, since this isn't exactly leading edge stuff (though it may be in the retro tech space!)

I've got a K40 laser engraver that I've had a lot of fun getting up and running with K40 whisperer on a Raspberry pi, and lately I've been thinking about getting a cheap 3d printer. Does anyone have an entry level 3d printer they like and want to recommend? What kinds of projects do you like to make? Anybody have a desktop cnc or other fun toys? Let's hear about 'em.
