I don't have an oscciliscope, is there any other accurate means of obtaining a signals frequency? Know anything about residual frequency, or how to achieve anti-gravity? I also wired up an invention that takes oily,contaminated waste water and through a process,recycles the water and separates all dirt,fuel/oils,ect. For use at any company that has ,operates,or uses vehicle/machinery wash racks.Complies w/EPA,local laws. If any interest,I could share design schematics.
