Thread: DIY Steel Plate Impact Detection

I bullet impact will be a near instantaneous impact nearly 10 times giving it a decent swing with a sledge hammer (8lb sledge at 50fps is 49 ft/lb ) There is a lot of energy transferred. The reduction of impact as carried through the post may well see the gear last longer .....

I really like the idea and I am not trying to be critical. I am trying to see if you can do this isn a way so that you get a decent life out of it. It sounds very interesting.

Very good feedback, good to hear the potential weaknesses to see how one can mitigate it. Potting up the electronics inside the enclosure is going to be important to get a decent life time out of it - you do not want components and solder joints to come lose. The challenge is going to be to have one unit that fit all applications - a 22LR as well as a large cal. Using something like this on short ranges for large cal (less than 350m) probably does not add much value, but it might be helpful for the 22's. But shooting at 800m+ on large cal's might be.

The best is going to be to get some of these units out in the field, and shoot at them until they break - and how they break.
