I have a 555 timer circuit that I made up. It has a frequency of 100KHz. When I attach it to my amp through a potentiometer the frequency seems to drop to 80KHz. Is this right? I wasn't expecting that to happen.
The way you can have exactly 50% duty cycle at all times would be to generate double the frequency and then divide it by two using a flip-flop ..I have it working at target frequency, the duty cycle isn't as close to 50% as I'd like but its not worth worrying about.
Hm … it looks like the veroboard must have been manufactured by Kuku-Maluku from Limpopo .. Funny as it sounds, the difference between 100pF cap and the measured value of 330pF is just to big .. Something else must have increased the capacitance, but what?The capacitance value is 100pF but on the veroboard it is measured at 330pF
