At last week's Seattle Maker Faire, Michael (11) became enamored with a Simon game, so we bought a kit to make one at home. (Those of you too young to remember, Simon was one of the first electronic games, introduced back in 1982. It had four buttons and would light one up. The player would tap it, then Simon would add another light to the sequence, which the player would then repeat, and so on.)
Today, Michael and I put the kit together. It was pretty straight-forward but it required some soldering. The last time I soldered was about five years ago when we built Herbie the Mousebot. Michael was really too young back then to solder, but today he did all the work. He seemed to really enjoy doing it and was very proud of his new game.
The Sparkfun Electronics "Simon Says" kit was very well put together -- good documentation and good quality parts. It cost about $30 at the show (although it's $24.95 on the website) and took us about 40 minutes to put together. We'll definitely get more kits. Hopefully, we can work up to Arduino stuff next.
