Although the 'make your own computer' is very funny to adults and people that understand the dangers of electricity and electrocution, I just hope no children see Dr Ashens 'home made computer guide' and 'try it' for a laugh. The thought of kids sticking bare wires into the holes of the power lead socket sends a cold shiver through me... Yes, my comment makes me seem like a kill-joy, I know, but I am an electrical engineer...
