What do you mean "successful"?

- not got killed playing with dangerous circuits;

- succeeded in making a circuits that did some voltage
  conversion without any standard product-proof tests
  to make sure device is safe, reliable and meets sine
  or similar requirements;

- developed a device better then TrippLite converters;
