Hello
you need to produce ac at very low energy, try my shema, just 3 volts, more energy you put in more higher the frequency will be
it's my own work, a gift for someone who need it

i have use it for many years, it may be unique
my next step is to convert it to an resonnator
Thank you mramos
so it is not my own ac generator anymore, i will have to be humble now !
i have some others shemas, i will submit to you before posting them !
i am please to meet some eminence like you in that
i expect that it can still be usefull to someone here
the resistor is 1 meg and more, the capacitor can be anysize, i have an another shema for electrolytic capacitors, you can put whatever you want in seri with the capacitor like coil or leds or speaker
resistor can be replace by variable one, or anything you want to try
you may add some transistor beside the battery to get other output
i am happy that discovery is already known, just a rediscovery
