Welcome. I wanted to provide stripboard layouts I've made to help people new to electronics and even the more experienced get into different aspects of electronics.

I verify the layouts before I post them.

Voice Bandwidth Filter for podcasts / youtube veroboard stripboard layout

This idea came about when someone was tweeting on twitter that they were having problems with rumble noise and high pitch squealing from some air conditioner unit. So I thought I would make a filter for people to combat such problems, basically this thing attenuates anything below 300Hz and anything higher than 3KHz which is pretty much everything outside of the vocal range.
This could be a useful thing to combine with the high quality Microphone Preamp I designed some time ago located HERE

It's been a while since I posted a project because as you (may) know I build up things before I post them so I know they work however I've had bugger all money to buy stripboard, I actually had to de-solder an old project to get enough to prove this one so if anyone can help me out with some stripboard I'd be most grateful!

    I'm going to have a play with it in a sort of home-brew intercom for my open car - the mic's are always going to be noisy due to wind noise etc, but this circuit might help a little.
    Thanks Paul
