Man this is insane, amazing work! POG

The 40106 is great for the first blinky light circuit, it'll bring you your first BEEP generator and you can even go further and make a proper sawtooth core synth VCO from it.

very cool!thx for sharing,man.so simple and so brilliant!

Great work. I have so many CD40106s that should be put to use. Great video

Thanks! They're such useful little chips. I'll be making an LFO controlled low pass filter video next.

Nice and simple, very well explained :)

This video is great! Thanks! I just put this together but I used three Schmidt's to make LFOs and Three to make the synth voices, Really wide range of sounds you can get out of it and I really like having the fine tuning control.

hi , great work , ive been working with 40106 and i have a question , how do you prevent from not burning your chips when inverted polarization of the current occurs? iv tried to power from a 9v-12 apadter but has burn some of mi components , thank in advance!

@observerb

Жыл бұрын

Always use a DC power supply, make sure it's not AC. It should handle 12v fine. I always double check every connection before powering it on for testing.

@observerb

@aaaaa no, maybe a beginner. Wall warts look the same if their output is ac or dc, easily overlooked. I thought they may be using ac when they mentioned an inverted polarization.

I wonder if you could use a 4017 to make a sequencer synth by putting it between the sync and the oscillator.

@observerb

Жыл бұрын

You can! I replace the potentiometer with a rail that goes to 2 4016 chips (there are better chips but that's what I had) and the 4017 cycles through triggering the 8 knobs going through the 4016. I'm working on that vid soon, I'll have the summer to finally do some stuff since I'm a teacher. Look for it soon!

Eurorack has a standard of +12, ground, -12. Mine only use +12 and ground with a capacitor to make it like +6, -6 for the audio signal.

@observer b... stumbled across this while wondering where to start on a homemade synth....I know just enough about electronics to be dangerous....I'm going to build this with a hc7414 instead of the 40106 because I have a bunch of them in my scrap bin....the 7414 Vcc is only five volts, not 12 like the 40106....I'm going to use the same values for the components as you did for a starting place, but don't know if the different Vcc voltages will effect the divider circuitry on the inputs and outputs of the inverters....or is it all proportional and has nothing to do with Vcc?? I'm going to give it a shot, but would like to have your opinion if you know what the outcome will be....

@observerb

Жыл бұрын

Not familiar with that chip, but if it works like a Schmitt trigger it should be perfectly fine with a 5v supply and the same components, at least enough to work and then make adjustments because it is proportional like you said. Let me know how it goes!
