Just trying to begin planning our Teen Tech Week Program. I know it's a bit early, the program is going to run March 11th. But, I was wondering if anyone had a source for all the supplies we used to create our little circuits? I had fun with mine and still have it on my desk as a sculpture, so I thought it would be a great way to get our participants engaged. I plan to do the circuit demo and then add the toilet paper roll switch. Then I want them to explore the pico boards and maybe make some simple programs using sensing. I think I am also going to bring some old controllers, like my Nintendo Power Pad, for us to dissect. Anyway, just thought I'd ask about successes or failures with this approach? Great suppliers for loose LED lights and Lithium batteries and wire?
