Still work in progress - like most of my projects I get side tracked and the projects evolve into something different. This project is no exception (unfortunately).

Current setup works well with...

Thanks, Urethane not something I knew about. Will definitely read up on it and give it a go. Can you possibly recommend some brands and type of urethane glue to start off with?

Not 100% sure I understand your explanation about the straps. Are you thinking the straps should have some sort of a hook attached on one end that hooks onto the top of the plate, and then the other...

Yes, I am happy with the range. And to be honest I have not done any antenna matching or even tried to improve the radio coms. If I slow the radio down, then the range will automatically also...

So, just came back from doing some more testing after the morning service. VERY happy with the results.

I tried microphones on my beehives some time ago, where I thought I could determine bee activity inside the hive, but the wind created havoc on my setup - so much so that I binned that idea. Here in...

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...

It is possible to play with the sensitivity of the sensor, but outside of the enclosure if you tap it with your finger it will be sufficient. Inside the enclosure a light pat with your hand on the...

Will be more than happy to put a couple of units together for the Toby shoot. How many gongs will you have out on the range?

Cost - I have not done the calculation yet. But this is based on...

Thanks Shootm

I was thinking that the 1000-1500m range would be where it would come to life. So if it can work reliably up to 2000m, then 1500m is in the bag.

The other use I thought of was for...

Interesting idea... Attaching the electronics to existing plates is a headache. If it full of rust or old paint then nothing sticks for very long. Yes, thanks - will try the duct tape idea. If it...

What sort of distances do you out to?

I have tested the radios on their own and got just under 10km out of them. When the transmit radio is mounted behind the steel plate, the signal get attenuated so I am hoping that more than 1000m...

Yeah, good point. If the projectile pass through the plate it would definitely be a problem. Would maybe be a good idea to only use it at longer ranges when the projectiles won’t pass through...

For a month or two I have been tinkering with this steel plate impact detection idea for when you go practising target shooting on your own. I found it sometimes difficult to hear a hit (earplugs)...
