My greatest fear was that someone would steal my ideas. So I chose an old, outdated idea of a rubber flash light holder as a learning experience.
Initially I felt the need for a flash light on my screwdriver when screwing in the dark. This was around 2003, the LED technique was developing and built in screwdriver lights were still very rare.
In 2006 I drew my first sketch of a rubber band holding a flash light and put it in my folder of inventions. It stayed there for about four years as more ideas grew and the folder had to upgrade to a large binder. A few of the other innovations were slowly taking form but never became more than crude prototypes. The fear of sneaky bastards was holding me back.
Taking the plunge
In 2010 I finally gathered some courage and decided to realize one of my ideas. Since the rubber flash light holder almost was obsolete it felt rather safe to use it as a learning experience. If I messed things up the experience would still be worth it.
Actually, the flash light concept was a good idea. There is clearly a need for it and today you can hardly find a machine without a built in LED-light.
