About me I've been a computer programmer since I first started typing in program listings on a Commodore Vic 20 when I was about 8. My hobbies include electronics, CNC manufacturing, photography, beer and winemaking.
I live with my wife and lots of left-over parts from unfinished projects in Lincoln, Nebraska, USA.]
