Re: New Microcontroller Zapper project

Nice work, nrlf !
I hope more people will follow your steps.

I liked your comment on your site : “This is no Cure for All Diseases device”

For the theory behind the zapper and use of frequencies, you can visit these pages

Be careful with the output stage. Yours has only a 100_Ohms pull up resistor. It should seriously tickle at low frequencies.
A push-pull stage and a 1k_Ohm resistor will make sharper square waves an give you better protection (and comfort).
Ever though to use a CMOS 555 as output buffer?
