Teen Tech Week and Adventures in Pico Boarding.

Hey guys,
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?

Thanks,
Hillary

For the batteries, this links directly to the coin batteries we buy.

For the LEDs, this links directly to the awesome dot sized LEDs. NOTE: if you want to use for jewelry, get the difussed. It you want to use for Bike Light, get the super strong clear ones.

Oh, thanks. I'll check out the 25cent holders. I've had no luck finding cheaper lithium batteries online. Thanks for the link! I really appreciate it.

The lithium batteries are pretty spendy (like, $3 each.) I had success using these 25 cent plastic battery holders that hold two AA batteries--that's enough juice to light up an LED. It's not as neat and tidy as using a little coin-sized battery, but it works. As for the LEDs, I'd also like to know where to get them in bulk. They are expensive at Radio Shack, and our local surplus place (Axman) only sells teeny tiny lights. I think the 10mm ones we used in January 2009 are a better size. The collective brain at Instructables recommended this website for ordering LEDS: http://www.ledshoppe.com/led10mm.htm

Oh, thanks guys! We already have five or six pico boards, but thanks for the info. I'll keep it filed away in case we have more participants than boards.
Thanks Keith!

Hi Hillary,
I've asked my staff to send me the links to the led's and batteries we use - and I'll post those

Sounds like fun! Do you have the PICO boards already? We have a local surplus store here called AxMan that you may be able to work with. It looks like it might depend on the quantity you're interested in.
