The 10 year old (as of 2003) Thinkpad notebook computer running QBasic in DOS is a nice “hacker” touch as is using 100 Watt light bulbs as power resistors. Pretty clever electronics, especially for someone that’s known more for his excellent woodworking skills than his obvious electrical engineering knowledge! [Read more...]
