- An all-black LAMY Safari fountain pen filled with a mix of water, Platinum carbon black, and inkjet printer ink.
- A blank sheet of A4, folded in half three times.
- My passport.
- A fully loaded Secrid card carrier.
- A really nice rock. It has been in my pocket for a year. Don’t think about it.
- A dumb watch. (Casio W-59. Very small, light as a feather. Green LED-backlight display. 50 metre water resist. Tough, within reason. Effectively infinite battery life.)
- A beta of the PinePhone Pro, equipped with dreemurrs archlinux.
- A USB drive containing all of my computers’ boot partitions and Archiso.
30 water : 1 platinum carbon black : 5 yellow : 5 magenta is the mix for octarine.
But seriously, 30 water : 1 platinum carbon black : 10 printer ink is a good starting point for mixing. That is about how sensitive the mix is to each type of ink. Pure printer ink won’t ruin the pen, but it bleeds like a motherfucker. If you don’t care about the next five pieces of paper, though, you can do some pretty cool stuff with it.
