Hi modretro!
I'm from California, and in my mid 20's.
Recently I've taken to tinkering with electronics to keep my brain from shriveling up and dying, as post university life hasn't been too mentally stimulating.
So far, I've mostly been doing refurbishment or simple screen mods on old handhelds. I've fixed up a bunch of gameboy advances, and added backlit screens to them, gameboy pocket backlights, repaired a PSP, a Sega Game Gear, and am currently working on a Sega Nomad.
Not completed any real in depth mods yet, but that GameCube Lynx portable is really inspiring! Between learning about resin casting parts, rgb output mods, LCD inputs, and electronics in general, there's a lot to learn!
Hope someday I have something cool to show, but for now I'm absorbing info and developing a solid foundation before I try anything too drastic.
