Experimental Throwie Designs

Sure, a throwie may not be something that needs much design work (see my first post about building a traditional throwie).  It’s just a LED, battery, magnet, and tape.  However, I’ve never been one to settle for un-over-engineered designs, especially when they have no noticeable purpose besides my making enjoyment.

So here they are, my experimental (advanced?) throwie designs.

Ping-Pong ball “Placie”

No-Tape Throwie

This throwie has the advantage of not having tape in between your magnet and metalic sticking surface, but the disadvantage of being knocked off sometimes.  The next design solves some of these problems.

Hybrid 6-Magnet Tape-Based Baper-Switch Throwie

The light will not come on until the paper is pulled, giving you ready-made illumination.  The tape keeps everything secure, while the additional magnets cause it to stick to your surface very easily.  These designs are all cool, but check out my next post for the “Ultimate Long-Range Throwie!”
