Re: [TCML] Camcorder Gap Syncronizing



A video camera is useless to synchronously view a spark gap. Unfortunately, the shutter speed has absolutely nothing to do with the images per second. changing the shutter speed does not change the frames per second. It will certainly work similarly to a strobe, but that strobe will not be synchronized with the AC line frequency and will be no use for checking the synchronizing of the gap. If the camera is not synchronized with the frequency and phase, it will not work as desired. The alignment will always be off and constantly changing. It can certainly be used for some very interesting video, but that is all.

Hi All,

I think I have come up with a way to check SRSG's using a camcorder. I was shooting aircraft at the EAA with my HD camcorder, and with the shutter speed at around 500 I was able to almost stop the propellers on the aircraft. It was kinda funny to watch a P-38 lightning fly past with it's props barely turning.

The camera has a 120th second setting as well. At this setting, it should stop a syncronous gap in it's tracks, and work similar to a strobe.

The only downside would be that it's not syncronizied to the 60 Hz power, so the alignment might be off, but it may still allow checking rotory gaps, and phase controllers.

So if your camcorder has shutter speed adjustment, you may want to give it a try.

I will have my camcorder at Cheesehead again this year, so if anyone wants to check this out on their rotories, we can give it a try. It should also slow down ASRG's too.
