Appreciate the inclusive first sentence! My keyring has keys, a Leatherman Squirt, flat-folding nail trimmer, AAA Maglite, and a leather invincible star charm from Mario. I also keep with me a bandanna (with a glasses cloth folded inside), a leather wallet similar to this design, and a Leatherman Juice Pro.
Phone is a beat up Note 8.
In my bag I tend to have a little sewing kit in a mint tin, small bandages, Ibuprofen, tin of petroleum jelly (way better than Chapstick) and a Dirtywave M8 hardware tracker for when I'm bored.
Of course in the M8's dedicated case there is an OM System LM-P5 field recorder, aux cable, USB-C cable, Moondrop Chu2 IEMs, various headphone adapters, a microSD card reader & adapters, and a TRS midi A-to-B adapter. And the M8 itself.
It's like a nesting doll of comfort devices. I won't survive the apocalypse but I'll be able to distract myself while mutants eat my flesh.
The Moondrops are solid, and considering the price, they're excellent. Not flat sounding by any means (they're what Kids These Days call 'fun') but good quality and cheap enough that if they break I won't feel bad.
The new Mini firmware sounds pretty solid. If you like the LSDJ style of tracking give the M8 a try. The next wave of Model 2s should start shipping toward the end of the month, so you might start seeing Model 1s for better prices on the local used market. Barring that, you could try M8 Headless for the price of a Teensy 4.1 board. That was how I started!
