I'm playing with electroluminescent paint. I can make the paint go paramagnetic and change colors by changing my power source from 240v 50Hz to 240v 1400Hz. Is there a device out there I can make or use that will create an AC voltage of 240v at 0.2-0.3A and be able to change frequency that much?
I can't design circuits but I'm capable of building them. Any assistance would be great. Thanks in advance.
