- / observerb DIY Synth for beginners. I'll show you the basics of breadboarding and how to go from a schematic to a breadboard with a simple example for a light bulb circuit included. The synth is based on a 40106 Hex Schmitt Trigger IC. It has a sync function whose rate is indicated by a flashing LED.

Most concise breadboard demonstration on RUclips! 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!
Thanks so much, that means a lot!
Do more like this!🎉
You got it! Thanks for watching.
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.
You should see my box of failed boards, it'd make you feel better, but you've got an awesome attitude, keep at it!
@@observerb The potentiometer on the output was BAD! Muther Trucker! I have the cleanest sounding version working on the breadboard now. Now to perf board it.
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).
Thanks for the feedback and notes! You're totes correct. "D'oh!" moment with the pin numbering. Also still trying to figure out how to say potentiometer correctly 😂
This channel is a gold mine
Thanks! And I'm just getting started.
I have built the first part, and it works.
But the volume only goes up, not down. And it continues making noise, even off.
Uh oh! Probably an unwanted connection or a bad potentiometer. If it makes you feel better, I have a pile of failed builds that's much larger than my successes. If you have it on a breadboard, you can at least tear it apart and try again. If it's soldered, might have to salvage the parts you can and give it another shot. Good luck!
very detailed, i understood everything, if u could make anotherone but with an lfo control to make a siren it would be amazing!!!!
Check out my LFO filter vid, you could use the vactrol to control an oscillator's pitch instead of the filter. Might take some fine tuning, but it could work!
It can be so annoying when chips just wander off LMAO ❤
Gotta keep your eye on em!
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?
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.
Thanks a lot! I've been a high school science teacher for many years, so that might have something to do with it :)
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!
I would but I don't really plan out my perfboards, I just plop stuff on there, so I may not be the best example to follow in that department. Generally, it'll be pretty similar to the breadboard layout and I solder components on as I take them off of the breadboard. I'm glad my video inspired you to make the build! Perhaps I'll do a general breadboard to strippard basics vid.
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.
Thanks! I tried to keep ot simple. If you want some really in depth knowledge on the components check out this guy's channel: ruclips.net/user/TheAudioPhool
What a great tutorial 👍
Thanks so much! Glad you enjoyed it.
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
No, I just should have pushed it in more, oops. Had my hands full filming and trying to do all the things.
Uno de los mejores tutoriales de RUclips !! Muchas gracias !!
De nada y gracias!
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?
Hey Bruno, I'm glad you like the video! The jumper goes from pin 2 (the output of the first schmitt trigger) to pin 3 (the input of the buffer trigger). The yellow wire is connecting 2 and 3 on the schematic. 3 and 4 on the schematic are the in and out of the buffer, which are comnected inside of the chip. I hope this helps, let me know if you have any other questions.
Its alive!
Twisted wires on the potentiometers and the jacks introduce indiction.
It reduces RF interference, which in audio gear is more important than a fairly small bit of induction. I'm curious about how much induction would actually affect this circuit. I really do appreciate the feedback! I'll do more research into which way is best for future videos. Maybe others will chime in with their thoughts.
Thank you for breaking it down so where I could understand and learn something new👍
You're welcome, I'm glad you enjoyed it.
Thanks much for making this! If I creat a second oscillator can I run it to the same output?
You're welcome! You can't run them directly to the same output, but can make a very simple "resistive mixer" using anywhere from 30k to 47k resistors at the output of each before combining them, it will cause a volume loss, tho, but it's not a big deal sonce these signals are pretty hot anyway. A potentiometer in addition to those resistors will allow you to blend them. Check out experiment 7 on this site to see a schematic beavisaudio.com/projects/cmossynthesizers/
@@observerb Oh awesome thanks for the link. That's exactly what I needed. Very cool stuff!
Awesome! How much for the components? Thanks!
The 40106 chip is about a dollar, the most expensive components are the potentiometers, about $10 worth of parts.
@@observerb That is incredible! I want to try this! Thanks!
Brilliant instructions
I will watch it now and rewatch it tomorrow morning at the office, sober 😀
Lol, cheers 🍻
yo best explanations on youtube, would pay for more of these for sure
Thanks a lot, I'm glad you're enjoying them!
Could you add a pot to the buffer to change the phase?
You could send the output to another Schmitt trigger on the chip, which would invert it. A switch could send it either way you want.
Appreciate you labeling the pin numbers for the 40106 on your schematic. Helps the old brain keep it all straight.
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!
Thanks for watching, I'm glad it helped!
Einfach Spitze erklärt. 👍
Danke fürs zuschauen 😃
YOU WERE RIGHT!!! Those CF bulbs are a complete Easter egg
Yeah, they're chock full of goodies! Have fun cracking them open.
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.
Thanks, and I'm glad you enjoyed the video! Yes, you could absolutely do that to get different pitches, that's actually how my sequencer version of this synth works- it cycles through different potentiometers. Your english is better than many native speakers, so don't worry about that!
Good ol tuofeng
Don't know what I'd do without it
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.
Thanks a bunch! That's the whole reason I make these, I remember how frustrating it was to not get a straightforward vid from the ground up for a build.
I love the detailed explanation in this video, please upload more videos like these!!!!
Thanks! Got a few more planned for the future.
great video to follow along to, thank you!
I love to hear that, glad you liked it!
@@observerb ...and I finally finished it (had to find some parts) Thank you, awesome learning experience. Do you have an insta account? I posted the end result there
Awesoooome. I always wonder about all the little bleepy bloop machines that have come into existence because of these vids haha. I would love to see it! Pop a link to it here and I'll check it out.
@@observerb the LED isnt working correctly (inverted) otherwise seems fine. I put a link in another message here
@@observerb youtube seems to delete links to insta... i'm there under @niemandenruiijs
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?
First double check all the connections, something always comes loose from the breadboard. Make sure all the polarized capacitors are going the right way, try swapping the chip out in case it got burned. Let us know what it was if you figure it out, it could be a lot of things so I'm curious to find out.
@@observerb the first thing i just realise.. I think i had used a 74hc14 and if i remember correctly it only goes up to 6v..i think i blew it up with 12v...ahahah
Great Video, I'm new at this stuff so learned a lot.
Thanks! That makes me so happy to hear.
Is it okay to connect the output directly to a laptop?
Yup! I've plugged it into guitar pedals, mixers, interfaces no problem.
thx for making this so easy to understand
That's the goal! Thanks for watching, happy it helped.
I would love to see you make a full DIY eurorack!
Moritz Klein on RUclips has some great builds with a proper +12, ground, and -12v eurorack power supply. I'm basically making a poor man's eurorack. I'll be building a sequencer module for this next, maybe an automated low pass filter bank before that (protoytpe is on my channel).
@@observerb you say a "poor man's eurorack" I think it's accessable to the most amount of people. I was just watching a DIY minimoog and the bill of parts was over $600 plus you'd need a keyboard with CV ideally. I'd really love to see what you come up with and what sounds you can get on an accessable budget :)
@@biggusb8281 You're 100% right! These builds are super fun and cheap, and also musically viable!
