Man I love these kind of circuits they are so much fun to play with. I’ve made them super easy all the way to super complex and you always learn something from adding and removing stuff from the basic circuit. Great video Paul, I’m going to have to build a punk circuit today and have some fun.
You would really appreciate Forrest Mims book on Timers and Op-amps, if you dont have it already. Very cheap book and loads of synthesizer examples there....and yes, this one is in there!
I always like it when people do things like this with analog circuits and breadboard. I've been in the digital world (FPGAs + microprocessors) for awhile also messing with audio. But there's really something special about doing it with analog components you can hold and see!
I had a flashback. A few decades ago, driving my mom's crazy with the exact same setup, but the output connected to the AUX input of my bedroom's stereo. Fun times, crazy sounds.
Great video! I'm a big fan of your channel. I've played with various versions of the Punk Console in the past, and experimented with sending an audio (with a microphone & amp) into, I believe, pin 5 you can do really WEIRD things! (I could be wrong about the pin... it's been a long time!)
I just did something similar with my APC circuit. I put some electrolytic caps on the output of pin 3 on the astable 555 to pin 5 on each 555 in the APC. It really added a nice "crunch"!
Again, I think this could be equally as well done with my favourite quad Schmitt trigger, where one gate oscillator is used to add cadence to a second or third gate oscillator. Like the 555, it is possible to take the signal from either the square wave output or the capacitor charge discharge voltage. May I also suggest that you do a few experiments with a double balanced mixer IC, to make ring modulators. There are such devices that work down to very low audio frequency, even though they are designed for RF/IF applications, as they are DC coupled, eg SA602AN. The ring modulator is the way that the Doctor Who Dalek voices were made.
Nostalgic Paul! Reminds me of the hours I would spend at Radio Shack (RIP) as a kid playing with the synthesizer they had on display. God I miss Radio Shack. 1000 to go almost there!!!! :)
I like these types of switching circuits and it's a 555. we can make different types like a Buck, Boost, Dc to Ac, strobe LED, and also a touch switch. Thanks for sharing Sir keep them comg more. 🤗
Sorry sir, permission to ask, if you want the LED to turn on for 1 second and turn off for 5 seconds and you can adjust it to turn on for 5 seconds and turn off for 1 second. 1 second is also 1 second. Only the frequency can be set... please advise. Thank you
What is the value of the electrolytic cap, that you using for the LFO? Also, what pins is the 10k trimmer connected to, is it 6 and 7? Please let me know. Cheers!
captured A screen picture, and have it saved into my schematics file. loved that little circuit : ) and how the resistance & capacitance of the scope leads change the frequency ever so slightly. would have noticed that even if you haven't forewarned us about it THANKS TO YOUR FREE KNOWLEDGE i now know stuff like that!! now to the "REAL BUSINESS AT HAND" 99.1K on your next video iv noticed but haven't looked at yet. (i thinks me's need's to buy that bottle of champagne) coz it's looking like any day now ; ) 100K!!! BOOM BABY, BOOM. also loved how the extra 555 turn it into a LFO. awesome extra tip.. nice one for that Paul because, as you know there's more than just making a speaker sound funny to done with these exact same circuits .. ; ) anyway C64 games to be watched!!
Cool. I will do this and disconnect the speaker. That is horrible. Do you recommend the lcr meter the proster for testing caps from your store. Oh and my wife is getting me the siglent or rigol from your store for Xmas. What do you recommend?
Noob question: What makes an LFO, an LFO? [from left to right] You have the 555 #1 connected to the 555 #2 [via pin 3, to pin 2]. Then you have 555 #3 connected to 555 #2 [via pin3, to pin5]. They’re all 555s but one is connected to pin 2 and the other, is connected to pin 5. So, is that what determines whether it’s an LFO or not? Please clarify. I want to learn. Thank you kindly
Tried out this little synth, it worked! But the LFO just added a bunch of static - no modulation, at all. I’ve tried different values of caps [all electrolytic], 0.1, 10, 22, 220, and 330 micro-Farad - nothing worked. Please let me know, what value you used for the cap. Also, I build this LFO very close to the synth circuit [ran out of space on the proto-board], could that be causing the static - the proximity?
@@learnelectronics I think this is a fair suggestion - especially considering those interested in tech who have sensitive ears or are autistic but still want to hear your words. we came here to hear what you have to say and learn, but we all know the APC can be a bit grating on the ears haha. It’s all about the mix between the synth and your voice. Thanks for the vid!

This project was really neat I liked it a lot . The dog and the wife not so much . Keep em coming Paul .....
This is so sweet! I've been looking for a good synth tutorial for ages now. Would love it if you made more videos on this topic

Keep them coming paul I recommended your chanel to my former colleagues from the royal corps of signals so hopefully some more subscribers
Advanced congratulations!.. More power.
Cool - I could see myself losing many hours playing with this circuit. Thanks for another great lesson!
I love these types of circuits, I'll have to build this circuit. Thanks, Paul.

You're right, pin 5 it is

Thanks for sharing Sir keep them comg more. 🤗
very interesting and very helpful
could run audio through this like maybe a guitar peddle
I almost heard, “I am Iron Man” in the beginning there.
Classic, yes i agree!
Have you tried if the sound keeps rodents out of the house? Big project. Thanks a lot
Very interesting circuit.
Now a high pass filter? :)
please do more synthesis!!! this is why i want to go to college to become an electrical engineer

Thanks Keith! I'm getting very to excited. Hopefully we hit 100k before Christmas. then I can start giving out some Christmas gifts!
Almost, The Main Street Electrical Parade.
Cool. I will do this and disconnect the speaker. That is horrible. Do you recommend the lcr meter the proster for testing caps from your store. Oh and my wife is getting me the siglent or rigol from your store for Xmas. What do you recommend?
Yes, the Proster is very nice. As for the Siglent/Rigol... I'd have to go with the Rigol. But you're gonna be happy either way.

Now that's heavy metal synth.
Replace both potentiometers with 50k ones and I assure you that you will have better results. The operation will be more stable.

Maybe it's the low quality speaker but I've never heard anything quite so annoying ever coming out of my Atari.
Nice 👍! What value potentiometers are those? And where’d you get ‘em?
Linear 500K at the 3 minute mark.
And the little blue white one is 10K
Kevin I think the schematic showed 470K.
@@kenlanier2131 thank you
@@marceichelsheim1740 thank you
Tough decision to give 359th like (LM358) :D Thanks!
I have built a few of these , I always add led lights to mine just for fun ......
Мужик! это круто! Я сделал как у тебя схему и всё заработало очень круто!
А схема лфо есть?
Nice video. If you want to build and play virtual modular synths for free on your PC check out on line VCV rack program.
I will, thank you
I don't think the wife would like this project. I will have to test when she is out.
Please, next time reduce the volume of the speaker 🙏🏻
Turn your volume down
Sounded fine to me.

Don't watch with headphones! Lol
How annoying !!! (The sound) :-)
