> Is it too soon ? I made my son (5y) a few wooden bricks with 2 or three nails, with a LED+resistor, diode, battery+safety resistor, switch, etc. He can connect the brichts with alligator clip wires. But IMHO at that age mechanics might be a more lasting interest: lego, meccano, fisher technic, etc. Wouter van Ooijen -- ------------------------------------------- Van Ooijen Technische Informatica: www.voti.nl consultancy, development, PICmicro products docent Hogeschool van Utrecht: www.voti.nl/hvu -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
