No, I haven't. I might in the summer. It looks like I am doing clubs after lunch in the school district's summer program.
Because the school also has a workshop set and a one-of-everything collection, most of my evening club attendees already know how to control a buzzer's volume. We haven't explored the light sensor much yet. Motors and servos get used extensively.
I've had 2 students so far who came up with the remote control car. One of them did so with the help of a few high school robotics team members (they volunteered for a couple of days). The other one was a member of the school's Lego League team.
Now that my semester is almost over, I will have time to explore other bits like the MakeyMakey...and upload projects finally...I have video compilations of my spring break camp too.
