If you rectify a 300 hz signal full wave that's 600 hz one of the Keely frequencies for splitting water.  Input that to the positive electrode and attenuate the negative electrode with 32,800 hz and there might be something to see.  Maybe not.

Good work jolt! That's a fairly clean sine wave coming out of the inverter. Did you modify anything to get the clean wave? What did the original sine wave looked like (before the mod)?

The output signal right out of the inverter is square before and after the mod, the mod only changed the freq. but when using a LC circuit on the ouput we can get a sine wave just like I did.

I used a series LC circuit. the LC combo was tuned for 650 Hz, and you can see that the wave is better at that frea, then when I run it at 420hz, the wave is distorted. I didn't have big enouph caps to tune it for the 420hz.

Ok, I was able to mod the husky inverter to output frequencies from 40Hz to 650Hz.

Using a transformer and a some caps we can also get a pretty good sine wave.



Very Nice work.  The main point here is you set out to do something and you were successful.  It may not have a large fequency range for tuning but what the heck I think its a way cool idea.  Nice work again!.

Please post the schematic for series LC circuit you used to clean up the sine wave.

Thanks in advance.
