Oh you haven't met a hardcore nerd until you have met me Everything I have is modded some way or how. Even my watch has a custom ROM and unlocked bootloader with TWRP. Also later this year I'm getting a magnet implant as well I use ALL mouse keys (38 total) for my G600 mouse, I have a 5 button foot pedal for gaming/vent, I make high power LED collars for my dog, etc. My gf hates me lol. The Pi is something I never got into but wanted to. I want a full home automation and unlocking via nfc or something close. I know Clark was looking to use a Pi for tank control too at some point. They really are an amazing piece of equipment for the price, especially the 3.
I do really like your 3d printer setup though, I had mine back a few years ago when it was still pretty rocky. I ended up spending more time tinkering than printing. I may have to try again with the new Prusa model coming out soon. You got any thoughts on that one?
