I am a college level electrical physics student (and so I do not have a lot of knowledge on the topic of electronics) and I am in the midst of writing a report on a project that was done throughout this session.

The project was the conception of a synthesizer, which I did pretty much by myself (I used some videos, manuals and other as sources). I ended up being able to build a functional synthesizer on a breadboard, and everything was working fine.

Now that I am writing the report, the teacher asked me to provide a functional simulation for the circuit, and so I tried doing just that. At first, I used Falstad, and was not able to create a functional simulation, for some reason the software did not specify (so I have no clue why the Falstad simulation does not work). Next, I tried using Tinkercad, and again, it didn't work. This time though, the software provided me with an explanation as to why the simulation didn't work, but I wasn't able to make sense of it.

Hence why I am here, asking for help in order to make a working simulation of the circuit. I want to know if I am simply making a stupid mistake or if it's actually a circuit that is hard to simulate using those software (In which case I will simply report to my teacher that simulating the circuit was impossible).

Here is the circuit diagram, made in Falstad (the first simulation that ended up not working:

Here is the actual working circuit, built on a breadboard Here is the actual working circuit, built on a breadboard The wires that are not connected to anything are:

  • 1 red and black for power supply
  • 1 red and black for the speaker
  • one black for the oscilloscope probe used
  • 2 green (on the keyboard) to plug in the keyboard.

The electrical components used are

  • CD40106B CMOS Hex Schmitt-Trigger Inverters
  • 2N3904 BPJ NPN transistor
  • IRF510 nMOSFET transistor (I think that this is the full name?)
  • The speaker's label was erased but I know that it's a 100W with 8 Ohm entry impedance.
  • 10k Ohm potentiometer for the volume
  • A 5W 50 ohm resistor (supports higher currents)

For the values of other parts, I think I've written everything on the circuit diagram. I didn't put all of the potentiometers from the keyboard since I don't know the exact value; they are tuned for a specific note. They vary from 1k to 20k.

As can be seen on the Tinkercad simulation, there are also (ideally) a few oscilloscope screen that I would like to show. This is what they look like when I use the physical oscilloscope with the breadboard circuit:

Oscilloscope out OscilloscopeOscillator out (connected to the input pin of the inverting schmitt trigger)
