Wondering if folks have ventured into other realms of DIY
Hmm, lessee-
In my 20s and early 30s I was partners in building a portable bakery that enclosed a 20' kitchen trailer, three commercial ovens, two generators, a 250 gallon water tank, 100 gallon propane tank, a couple of mixers and a commercial gas fired coffee making station. Took a week to set up and a day to tear down.
I've built four guitars.
I built a custom heavy barreled .308 rifle based on a VZ-24 bolt action.
I built a video projector from scratch, and the screen.
I built a cold camera for a telescope in high school.
I turned a 1969 Alfa Romeo GTV into an autocrosser back in the 80s.
I have from the ground up restored film cameras, antique radios, vintage audio gear, early photography strobes and restored a few watches.
I took a hologram once.
I rebuilt a 40's vintage oil furnace last winter.
Built my first cafe racer when I was 23. Now I am building a custom Honda CBR.
Once I tied a moth to a safety pin with some thread and attached it to a scrap snarl of fishing line tied to a stick. Caught a 6" brookie with it.
Used to make my own gin.
Oh yeah and I have done a little bit of audio DIY too.
