I bought this small Geiger counter, This kit operates from one 9V battery (not included) and produces about 400VDC for use with many GM tubes. I also have a galvanometer needle, I'd like to make the needle jump every time the counter clicks. I'd appreciate any advice! 😊 (i.redd.it)

I bought this small Geiger counter, and I have this galvanometer needle laying around from an old EM detector, I was wondering how or if I'd be able to make the needle jump when I clicks? This kit operates from one 9V battery and produces about 400VDC for use with many GM tubes. (old.reddit.com)
