You can get some pretty complex sounds with just a few basic building blocks, repeated a few times.

Handmade Electronic Music Routledge, ; chapter Check each oscillator out one at a time, by listening to each output separately. Oscillators can also control other oscillators, making more complex tones. In addition to changing them manually, we can also use one oscillator to control another oscillator. So we have oscillators, and we can change their frequency by changing the values of either the resistor or capacitors.

CMOS – CMOS – Six inverting Schmitt trigger

This tutorial shows how to build oscillators on a solderless breadboard. Data sheets also often have sample schematics that can help get you started using a new chip. Or, hold the two resistor leads in your fingers and squeeze to change your skin resistance.


Get all 3 oscillators happy before continuing. BTW, most chips do different things and have different pin-outs. Once we start stringing circuits together, one circuit controlling another circuit… oh, boy.

All 3 oscillators signals are now mixed together, out to the amp. You should be able to hear the first oscillator switching the tone of the second oscillator back and forth between low to high. So you can get 6 oscillators out of one chip. 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.

Tom Bug’s BugBrand electronics page. Or wire in a pot variable resistor to control the pitch. We can do the same thing here. SO those are some basics: Try using variable resistors and start monkeying 401006 the rate of the first oscillator, then the frequency of the second… then both.

Oscillators produce AC signals, which we can amplify and hear as tones. You can also change the capacitor value… swap in some different ones and see what happens. Ov course, you might have something different by now….


After experimenting and finalizing your design, you can transfer it to one of our Oscillator boards to make it more gig-worthy. The 3 k resistors on the right ccmos the mixer resistors. 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.

Replace the resistor with a photocell. We want to mix all three oscillators together. We used a different integrated circuit the chip last week to build our amps; it had only one circuitry block in it, a single analog amplifier the right-pointing triangle on the schematic. Start with what you had for the last circuit, then:.

On chips like this 4106 multiple elements, all the inverters on the chip are the same, so you can pick whichever one makes the c,os easiest.
