Wireless Power Transmission, Part I

Jamison and I are starting an engineering project1Jamison’s project is based on the Instructable, “Low-Power Wireless Charging. for his school’s science and engineering fair. This is the second year his school’s fair accepts engineering projects. Instead of doing a science experiment using the scientific method, we get to engineer:

  • Identify a problem
  • Research how others have solved it
  • Develop our own solution
  • Refine our solution

We want to transfer electrical power over a short distance without a direct, hard-wired connection. Here’s where we’re starting our research:

This should be fun. :-)

But wait — there’s more

T-Shirt Launchers

I was at a Blazers game this past Monday, sitting in the last row, watching the T-shirt launchers. The picture shows our view.

As far as I’m concerned, sitting in the cheap seats, T-shirt launchers could use even more power. Bounce those T-shirts off the back wall! ;-)

I didn’t realize that Intel had sponsored this competition for T-shirt launcher designs. The winners mentioned in the video below are visiting my Intel site today. Congratulations, Arlington High School!

Turn a kid on to Engineering

Jack Ganssle, embedded systems guru, challenges you to turn a kid on to engineering.

In the ’60s and early ’70s a national Apollo-era fascination with things technical helped groom youngsters for an electronics career long before entering college. It wasn’t (quite) as dweebish to enter a science fair as is the case today. Kids were excited about science and engineering.

Above all, perhaps, was the specter of ham radio. Like so many others of the time, I got my first ham license at age 16. Though even back then sophisticated operating modes like single sideband (SSB) existed, most of us teenagers couldn’t afford the latest cool technology. We were forced to build our own equipment.

“Forced” is hardly the right word, since building stuff was much more interesting than actually using it, when and if it finally worked.

It brings back memories for me: endless hours playing with Legos and my Erector set, the two-stroke lawnmower engine spread out across the shop (that never worked again), the crystal radio my dad helped me build, the blown fuse from connecting a ham code key using just an extension cord (don’t ask…), the ham radio receiver in my bedroom, the Jacob’s ladder in the garage.

What do kids play with these days that interests them in hardware? Ganssle has some suggestions:

Get a Digikey catalog. Surf over to www.imaginetools.com. There are indeed a lot of resources for young EE-wannabees. Check out www.arrl.org, or Ward Silver’s Ham Radio for Dummies, Wiley Publishing, April 2004.

Sounds like fun!
