An example of testing and early failures…
I built a small test rig which gives off similar RF emissions to an operating laser tube so I could test run the unit without using the laser. After a couple of hours the clock stopped. Cutting the clock apart revealed a long plastic shaving caught up in the gear train and although the mechanism was beautifully constructed the Chinese manufacturers of this device seem to have absolutely no idea of quality control. Cleaning, removing the debris then gluing it all back together seemed to have resolved the issue and the 24 hour test then continued without fault.
Prototype #1 is now off on it’s travels for further testing with professionally manufactured laser machines whilst prototype #2 is now running 24 / 7 until destruction.
Tweakie.
