wow that's very nice. superb idea
I really enjoyed your article Dave,
I'm not a parent myself yet but I really enjoy computing and I try to make my 2 nephews enjoy it as much as I do and sometimes it's hard to make them sit with me for even 5 minutes hahaha they like to run around.. that's what kids do... so I introduced them to gardening and you can't possibly imagine how happy they are with a shovel in their hands and picking their own food from the ground...
then when they get tired i get them inside for some fun with LEDs and my raspberry Pi.
other than that I find myself enjoying the lessons on codeacademy. great way to learn for the kids... small goals are sometimes more rewarding for them because they get to see results faster than coming across big problems:)
keep up these nice articles ill be waiting for the next ones
