On chips like this with multiple elements, all the inverters on the chip are the same, so you can pick whichever one makes the layout easiest. You can get some pretty complex sounds with just a few basic building blocks, repeated a few times. After experimenting and finalizing your design, you can transfer it to one of our Oscillator boards to make it more gig-worthy.

Oscillators can also control other oscillators, making more complex tones. So you can get 6 oscillators out of one chip. Or, hold the two resistor leads in your fingers and squeeze to change your skin resistance. We can do the same thing here.


Handmade Electronic Music Routledge, ; chapter You can also change the capacitor value… swap in some different ones and see what happens. We want to mix all three oscillators together. You should be able to hear the first oscillator switching the tone of the second oscillator back and forth between low to high. Check each oscillator out one at a time, by listening to each output separately.

The 3 k resistors on the right are the mixer resistors. BTW, most chips do different things and have different pin-outs. So we have oscillators, and we can change their frequency by changing the values of either the resistor or capacitors.

Start with what you had for the last circuit, then:. Replace the resistor with a photocell. Or wire in a pot variable resistor to control the pitch.

Oscillators produce AC signals, which we can amplify and hear as tones. We used a different integrated circuit the chip last week to build our amps; 401106 had only one circuitry block in it, a single analog amplifier the right-pointing triangle on the schematic. Ov course, you might have something different by now….

This tutorial shows how to build oscillators on a solderless breadboard. Try using variable resistors and start monkeying with the rate of the first oscillator, then the frequency of the second… then both. This is one of those schematics that omits the power connections, and just shows the basic circuit building blocks although it does show the pin numbers.


Tom Cmod BugBrand electronics page. A sweet setup would be 3 pairs of FM oscillators with all three outputs mixed together… speed controls on the slow oscillators, photocells on the fast ones, individual volume controls… you get the idea.

Get all 3 oscillators happy before continuing. SO those are some basics: All 3 oscillators signals are now mixed together, out to the amp.

In addition to changing them manually, we can also use one oscillator to control another oscillator. Once we start stringing circuits together, one circuit controlling another circuit… oh, boy.

Data sheets also often have sample schematics that can help get you started using a new chip.
