This is the Thundering Herd Christmas which means my nephew and his family will be attending and one of his sons is interested in robotics and such and 3D printing. I was thinking of throwing some of my Arduino stuff in my suitcase in case he wants something to keep occupied.
BUT - 8th graders I think learn different from gray haired adults. So can anyone suggest some appropriate learning materials and supplies?
Parallax has a robot, it looks like line following can be added later, Parallax has been doing education stuff for many years and their books are well written, this robot is based on a frame that has been used for some years.
Sparkfun also makes a robot but I was not impressed with it's design and had problems getting it together, finally set it in my box of "to get to later" things
Books and guides can be difficult to sometimes rate from the title and description, I have bought a couple that were not all that well written despite being sold by reputable vendors
Something with a physical component to it i.e. something that moves. So motors or servos are good. Maybe build an apparatus that sorts balls by colour and pushes them into different hoppers.
Blinking LED's are fine for some of my learning - but for this I am thinking of more visual things as suggested by @ wildbill & @terry's things have a lot of parts - - so I am thinking of several ideas - still have some time to go
