Can you post a sketch of your circuit? It would be helful for us to see how you organized your design. A sketch would shed light on your power supply and the overall signal flow.Hi, I'm the obsessive ultrasonic transducer questioner. How would you go about making an oscillator out of the 4011 to drive a peizo transducer?I found a circuit in an electronics book that uses a crystal, but it doesn't seem to want to oscillate.
Is this for an ultrasonic fogger? I thought those frequencies were in the 25 - 40 KHz range. My old ultrasonic cleaner ran in that range.
The circuit that I am trying is actually from an electronics book. It's not mydesign.Can you post a sketch of your circuit? It would be helful for us to see how you organized your design. A sketch would shed light on your power supply and the overall signal flow.
Thanks, I'll give this circuit a try. I need to get a 1mhz crystal first. That software is cool. Is it freeware?Give the attached circuit a try.
Basically, it's an adaptation of a crystal oscillator circuit from TI's CD4045B datasheet. You really should only need one of the 4011's gates to get it going; the 2nd gate is simply an optional driver circuit.
The values of R may need to be increased. Crystals don't simulate well in the sim I'm using.
That's correct - you can't breadboard a crystal oscillator circuit. There is simply too much capacitance in the breadboard itself.I am interested in the comment about building these on a breadboard. it that really the case cause I just try to prototype one on C4060 with a 44Mhz Xtal but getting nowhere.
