RE: Lumenocks

Ive never bought one but did build one last year for a buddy to see how easy it would be. They are very simple in design.

Code:

                         Battery
                            _____
                           (_____)
                           |     |
                           |     o
                           |    /  Switch  (magnet attached to spring arm to latch with forward momentum)
                           |     |
                           \     /
                              @
                             led

This worked for me. Just used a 3v led. Switch was a piece of flat spring with a small magnet on the end of it. It bent inward. When the arrow moved forward fast, the magnet would catch and the light would stay on till a good jar broke the magnet bond. Cost about $3 including the battery.
