My 9 year old daughter built and entered a "Musical Sprinkler" in our local Berrien County Youth Fair this week and got Grand Champion. The unit is based on a Lynx MR16 board (thanks RJ) that she completely assembled and soldered herself. This is controlling 7 12v water valves from Ebay. I taught her LOR to sequence it to music. I told her after the fair I have a pile of boards to assemble! She is very interested in doing some sequencing for Christmas this year!
