i forgot to put the dot in the simplified schematic so the top positive goes to both resistors and the pin 14 of the 4011 ic
Steve, with great respect i doubt your audio frequency counter has the ability to read out megahertz frequencies...You mentioned in your previous video that the frequency counter was showing frequencies in the Kilohertz range which you thought was weird...Remove all that wiring from your previous video and leave the frequency counter standing on its own without any wiring attached to it..4011 its a 4011 frequency doubler circuit
Good luck sorting out your frequency drifting problems cobberthe frequency counter is a 1 hertz to 50 mhz counter of course it can read megahertz thats in the design and data with it its stamped on the kit 1 to 50 mhz frequency counter the wires from it go to the signal output of my frequency generator thats how it works and it counts the kilohertz ranges are dependent on the capacitor values used for each frequency generator and ive. selected that many values for various frequencies and they cover low frequencies and kilohertz ones and megahertz so ive got many values for ,my frequency counter reads any frequencies not just audio thats why they call them frequency counters and i run them to piezo speakers and get audio signal outputs for the various frequencies and due to the extra higher audio output signal sounds being so high thats why i thought it was wierd as then its more than double the frequency doubler was meant to put out when i run them through the 12 volts dc powerd frequency doubler , ill do more test latter busy trying to find more parts jaycar is out of stock on two, and if i tried to measure the same frequency output from the output thats where i got the frequency measurement from the first place before i switch the pezios on and due to some capacitance effect it jumps higher to and turning of the piezo seems to still show good frequencies to the signals of various ranges like hertz and kilohertz to megahertz run to the pizeos for sound signals which vary to the frequencies ive got outputting and they work to speakers to i get various audio sounds from various frequencies they dont have to be voice just ac signals like audio ac types
