555 Mind Mangler

We made a Mind Mangler out of a 555 timer chip, this creates a very high pitch humming sound that makes it very difficult to find and detect. It annoys the living life out of our victims a.k.a roomates. Visit our website at www.hm-innovations.com for additional projects.

I checked out your site. It would be really cool if it didn't have ads all over. Every time you click on something you get some sort of ad. Very annoying!

Projects are cool though.
