555 Signal Generator
Posted: Mon Mar 17, 2014 1:03 pm
so i have decided to try and tune my coil with the help of a 555 Signal Generator.
I have the circuit built but i am having a hard time figuring out how to make it output high enough frequency to work for this application.
I have been crunching numbers on different calculators online and i dont understand what it takes to make the 555 output 200-350kHz
with my calculations i either need a really small cap or a really small pot... im sure someone has built one of these before, so fill me in with what components to use, PLEASE! thanks!
this is the circuit i have built: http://forum.allaboutcircuits.com/image ... ble555.jpg
