Volunteered to do some technical education at my elder son's primary school.
Went to town on eight systems from P3 to C2D with about 30 11- and 12-year olds in groups of 3 or 4, disassembling them, then letting the groups who finished that soonest start rebuilding them. Two groups managed to rebuild systems to the point of POSTing, with one we added an optical drive and booted Knoppix too.
No coincidence that was the P3 system - partly because it was easier to work on, partly because it was the one I only entrusted to the children I felt would treat the stuff with respect - who of course tended to be most competent too. Nonetheless someone (I suspect the substitute teacher who tried to - hurriedly - help tidy stuff up at the end) managed to knock an SMD cap off the STB Velocity 4400, so need to fix that before doing a different group next week.
They were in awe of seeing something built the better part of a decade before they were born boot up after they had - with no more than some intentionally general hints from me - built it, angrily beep when they hadn't seated the DIMM properly and then reward them by successfully loading an OS. Then they almost lost it again when I told them that the oldest, lowest-end smartphone in the class outperformed this big system by an order of magnitude.
Oh, and all this time my 3-year old sat on a table as a sort of mascot, either eating fruit he purloined from somewhere in the classroom, or sitting on a table playing with screws and screw drivers.
Dead tired now, but very rewarding corrupting the youth in this way 😀
