Stroboscope with optoisolated external input
This is another strobe i designed. The current limiting is again ensured by
ballast from the fluorescent lamp, because this method I found the best.
The strobe is designed for external trigger control. The input is galvanically isolated by optocoupler.
Warning! The device is galvanically connected to the mains. Before handling it,
disconnect it from mains and discharge the capacitors.
The entire device must be suitably protected against touching live parts.
The lamp heats up and improper mechanical design or location can cause
risk of fire. For any injury I do not take responsibility - everything you do at your own risk.
