Hello there, I found an interesting DC/AC converter design for 50HZ 220V.
http://www.uoguelph.ca/~antoon/circ/555dcac.html<p>I was almost very happy until I read the description. There is R4 potmeter which is supposed to regulate frequency. Without an oscilloscope how can figure out what frequesncy I have? I guess there is no way.
