How to Breadboard a Drone Synth 40106 IC 

Most concise breadboard demonstration on RU-vid! If every electronics content creator were to do this, there'd be WAY more diy synth builders and creativity in general. Thanks and well done!

This channel is a gold mine

Good, simple oscillator circuit, and well-explained! Just a couple small notes for anybody building this: - the power pin on the hex inverter is pin 14, not 8. Pin numbers go counter-clockwise around the chip starting at the upper left, so pin 8 is the lower right and pin 14 is the upper right. Not a huge problem if you are following visually, but if you're looking at a datasheet, it'll say pin 14, so be careful. - the AC coupler will be pretty fragile without an extra output buffer; any load on that, like driving an unamplified earphone or speaker, will slice off most of the negative side of the wave. so long as whatever the output is connected to has a buffer of some kind (like an amplifier) it should be okay, but something to watch out for. - it's a good idea to ground the unused input pins of the inverter; if left to float, it can generate a ton of noise, which can make it into other parts of your circuit via the power supply rails or capacitive coupling (which breadboards have a bunch of).

VERY Helpful. I appreciate that you slow things down. Your instructions are just right. Too many Synth Dudes talk like the Micro Machines guy from the old TV commercials, or mumble into their shirts, so they are difficult to keep up with. Keep Up the EXCELLENT WORK.

This is awesome. Not only you're showing each step but you're also explain the function of each component and how they work together. Awesome lesson.

What a great tutorial 👍

Appreciate you labeling the pin numbers for the 40106 on your schematic. Helps the old brain keep it all straight.

Thank you for breaking it down so where I could understand and learn something new👍

Uno de los mejores tutoriales de RU-vid !! Muchas gracias !!

I love the detailed explanation in this video, please upload more videos like these!!!!

yo best explanations on youtube, would pay for more of these for sure

Excellent walk through! Some new things learned. Special thanks because your point about grounding output jacks pointed me to relook at a problem in a circuit I have done several reworks of. In the end grounding just fixed it! Thank you and I have subscribed!

YOU WERE RIGHT!!! Those CF bulbs are a complete Easter egg

Brilliant instructions

I will watch it now and rewatch it tomorrow morning at the office, sober 😀

thx for making this so easy to understand

Great Video, I'm new at this stuff so learned a lot.

It can be so annoying when chips just wander off LMAO ❤

This video is awesome! Most of the videos I've seen about simple oscillators synths just assume you know how how to connect you power supply and how to output the audio.

Do more like this!🎉

Einfach Spitze erklärt. 👍

Can you do a follow up video for transferring the circuit onto a perf board? For us beginners out here :) this video was great I can’t wait to build this!

very detailed, i understood everything, if u could make anotherone but with an lfo control to make a siren it would be amazing!!!!

Eine sehr detaillierte Anleitung👍 Da möchte man glatt mitmachen, wenn auch laienhaft. Der Link funktioniert nicht, deshalb: welche Bauteile benötige ich (Liste)? Wo wird der Audioanschluss gesteckt?(- im Video nicht eindeutig erkennbar) und kann ich den Ausgang ans Audio- Interface anschließen?

I am so thankful for this content, you're giving me the extra that uni does not. Really appreciate that. Btw, one question, you connected the jumper or buffer (yellow) from pin 2 to 3. But in the schematic you wrote 3 to 4. Was a mistake or is it supposed to be like that?

Twisted wires on the potentiometers and the jacks introduce indiction.

Its alive!

I would love to see you make a full DIY eurorack!

Hello. Awesome video. I'm a beginner on trying to make synths and your video help me a lot on understanding how they work. I just have a question: If I want to control the pitch of the synth with buttons instead of the potentiometer (like a keyboard) I could use some switches with different resistors and by pressing every button I could get a different note? Or there is some other method? Thank you and sorry for my broken english.

I have built the first part, and it works. But the volume only goes up, not down. And it continues making noise, even off.

Thanks much for making this! If I creat a second oscillator can I run it to the same output?

Could you add a pot to the buffer to change the phase?

It worked, but for some reason after a few seconds... well let's just say "MURDER WAS THE CASE" , any toughts on why i have no more sound?

Is it okay to connect the output directly to a laptop?

1:50 Is it common with these type of plugs, that the metal prongs are exposed while carrying voltage? Something like this is strictly forbidden here, because thats a death trap

Awesome! How much for the components? Thanks!

Good ol tuofeng

Built it on the breadboard and moved it to the perf board and blew it. No output, even got the harvested LEDs in backwards. Ah well, time to break it down and give it another shot. Perf board tip, don't crowd yourself people. I wish I would have started in the center.
