Thanks for all the support, as the above is how i keep this project afloat, as i don't think i'd be able to develop projects like the furby organ and gameboy mega machine otherwise so thanks! :D.
Im giving away 5 component packs, and a DIY modular furby i built on a livestream a week ago, on my patreon next week! so if you want any of that go check that out!

Thank you for making the unobtainable obtainable to those willing to build. THIS I can afford.
im trying to get a CEM3340 chip but i cant find them for under 50$ so its become a bit less affordable lol..
the super simple oscillator still is a dirt cheap build
Lol
@@nyrbsamoht try the AS3340 Its basicly the same chip but around 10-12$
i remember you
you probably dont care but does any of you know of a way to log back into an Instagram account..?
I was stupid forgot the login password. I appreciate any tricks you can offer me.
You're the only guy I've found who describes building a module like an announcer talks about a sports game.
Wait, You mean I can build my own modular synthesizer in my house? What kind of wizard are you, and where have you been through all my life? Seriously, there are no words that would express how happy and grateful I am right now! Thank you very much for that, instant sub from new declared fan and disciple!
If you are interested in this topic, check out the "Synth DIY" group on Facebook, tons of people there building synths of all kinds.
@@cabintechgloballlc5337 Oh my God! Thank You very much for the info! I'll definitely check that group!
This is like an alternate reality where Johnny Rotten got into analog synthesizers instead of punk rock
You mean like on Rottens work with PIL? Or his solo album?
Simon Gunkel I meant it more like that he resembles rotten
his band in which he plays guitar would have seemed 100% normal in the eighties. I often wonder what his parents look like or listen to. maybe they listened to 60's music in the eighties and then he was born in the 90s, so there's like a lag. or it's a cyclical thing and all styles are bound to come back which is why I'm being subjected to the eighties for the second time (although this guy is totally amazing and funny). there are so many retro bands now. so you can imagine a musical universe that supports all periods simultaneously. but in just a few more decades, assuming one style per decade, it's pretty far out.

What a classic. You're the best thing that has happened to the synthesizer world since Bob Moog. Greetings from Spain, buddy.
This is amazing. Even years after the release of the video still one of the easiest (if not the easiest) of functional DIY VCO I have seen. I am absolutely going to try and build it.
Just started a DIY Eurorack series on my channel. I'm HIGHLY inspired by you to do this. Mine's using kits, though. I'm hoping it'll be a good place for people to get started. I love what you're doing here, man. Seriously one of my favorite RUclips channels of all time.
Dude you are the best and my favorite circuit bender that I’ve seen... you are hilarious and remind me of so many of my friends... you are always welcome to stay with me or my community if you ever come to Austin Texas.
A VCO on a chip? That is so awesome. I didn't know about it untill now.
Thanks for the video.
brah, you never heard of dco synthesizers? :)
The famous Oberheim OB-X used the very same chip.
Nice to see got the lighting sorted for this one.
The narrative style Is awesome, thanks for your videos ☺️
Collin Furze of synthisizers ... I didn't knew there was an osc. chip that could do 1V/oct. Some analog noisemakers don't care about 1V/oct. others used complicated exponential coverters to get it.
Collin furze of synthesizers... lol true
Extremely based old school diy RUclipsr reference
Man you're a true entertainer, i've had a really great time watching this! And the gear works great!
Man I've watched alot of your videos in my life and I didn't know you did these lessons. Here I am at 30 with 20 years of music experience wanting to make my own pedals and devices. Thank you for making this!
This is MASSIVELY exciting! I am loving this series!!!
Congratulations on 100,000 subs! Well deserved!
I'm always amazed at what an absolute mad scientist genius he is. Keep buzzing.
You and Even Kale are by far the most entertaining tech guys I watch.
Thanks alot for these tutorials, there aren't many people on youtube that explain it in a way, that most people can understand.
I was wondering if you will make some videos where you explain/show the complicated methods of making VCO's, filters etc.
Dude, you rule. I was able to get this thing working on a breadboard easy peasy thanks to your rad-ness
If only I had 100th of your enthusiasm.
Youre an inspiration.
Oh my gosh, this is thrilling!!!! Can’t afford those vintage synths, but now I can try to get that sound out of my DIY synth!!!
Rowdy resistors.. Your build montages are awesome.
It sounds so clean and crisp
I don’t know what any of this is but watching your videos is so interesting!
Thanks Sam, genius, I finally finnished my TD-616, (Twonk Drone-616 the number of the beast from the original Hebrew scriptures) using 18 of your super simple oscillators, the filters are a bit weedy, but I'll be watching your vids and upgrading them ASAP. When I get a vid of it on youtube I'll share the link. I've never built anything like this before and I wouldn't of tried if it wasn't for your inspiring and easy to follow destructional video's, keep up the good work.
Thanx. I built one with the as3340. It worked right away.
Just built one using the as3340. I get this weird thing where when I plugin in my beatstep pro it plays super high pitch and I cant tune it for shit. did you happen to run into anything like that? Banging my head about where I might have gone wrong.
i tried to build it with the as3340 too but i couldn't get it working... i checked, rechecked and rerechecked a thousand times the schematic and i haven't found any mistake, i also checked my components , they're good.... I'm missing something and it drives me crazy hah
does anyone have tips or common mistakes not to duplicate ? (i'm a beginner if it wasn't clear enough)
thxxxx
@@gillestinguely same thing for me ... I've built three of them and also onr digital to analog sequencer and the cv is totaly out of reference with the tuning ....and the scales are like in reverse ( the higher note shown on the display of the seq the lower note generated by the oscillator) suppose to be exponential but ... welll ... i don't know ....
Been looking for a video like this for weeks. You've got to be one of the best guys on RUclips. Any way to get a square wave?
yep like i said in the vid, i will be adding addons to this circuit, this is the core of the module, ill be including optional addons. square wave out + PWM in will be one of the add ons, only requiring another TL072, 10k resistor and a couple of jack sockets. i still need to finnesse, but you can definitely work it out if you look at the CEM3340 datasheet :)
The add on is pretty simple, a comparator on the triangle out (saw might work too?) and the width is chosen by changing the voltage it's being compared to
its even easier, check the CEM3340 datasheet, it already has square wave out, i just figured it would be a simple addone with 1 tl072 for input and output
If we are planning to do the add-on's, would it be worth putting a tl074 in now instead of using two tl072's?
yeah totally. would be an option later on. this just seemed easy for now, but yes. totally. when i do the square-wave one ill plop a tl074 stripboard layout in too
Love the Channel man can't wait to give my own modular synth a shot . Been wanting to give it a go for a while, this is EXACTLY what I needed to get me to give it a go!!!
I watch your videos all the time! As a amateur synth builder you have helped me a bunch! Thank you!!
I was looking up colpitts oscillators and your video caught my eye. You give a crazy vibe, and that made me watch your whole video 😆👌🏼👌🏼👌🏼 Awesome, you really spent the time making this stuff, tape as you do, and explained too! that’s a lot of talent there👌🏼
Best channel on RUclips.
Extremely happy I found this channel
Raaaad and super rad on the stickers man. Stoked to see mine made it!
Whoa! You built your own Braids oscillator! So cool!
Man you are my hero! I was looking info to build my own 8 oscillators Swarmatron and...found your channel. Yhis is the best possible begining ! Than you so much for so invaluable info
"No Smoke!" = Sign of success! 😁
built it. gonna pair it with another as3340 . bloody brilliant sam.
Been waiting for you to do something like this. Looking forward to the whole series. :)
Nice one for posting this one Sam educational and fun to watch my man 👊👊. POW !!!!.
Love the drill bit tip its cheaper than the supposed proper which pretty much does the same thing .
Looks like I'll be building at least 10 of these, thanks man. Guy looks around the internet for a year trying to find an easy 1v/Oct schematic for Euro rack. Only because he forgot you were awesome. Sync would be cool though . I can picture ten synced up with a little detune😉
I just stumbled on this DIY series and im so excited for more, these videos are amazing. Keep up the good work my dude. Subscribed.
I built one !!!, mines just got some things to work out with the PWM controls not controlling very much ...yet...lol. might be a bad pot, they were pretty affordable ones.
Also I built the FC power-bus as well, that went without a hitch and the sequencer is almost done as well.
Keep em coming Sam!!!!
were building them...
..And thank you so much for these projects!
changed my life.
proper procrastinator now
:)
worked em out. love it, going to add the h/s sync and FM mod :d ... thank you SAM ! so excited for my filter on its way rn.
Sam, you are so bloody awesome!
There's approximately one word to sum this all up: brilliant! I am going for 1V/octave because there might be three parts (MIDI-CV-MIDI, analog sequencer and the synth part obviously), keeping it standard. Always say "never", I'm not going modular, I just want an analogue mono synth with as low expense as possible.
approximately one word
This guy is an absolute genius
Congratulations to 100000 subscribers!
ta-daaAAHH. made it! i now have one of the above! after hours of faffing about with it not working i tried a new op amp, worked right away. i am delighted! at a bit of a loss now as i own nothing that make 1v/oct signals for it. so i am off to make a resistor ladder push button keyboard........
Lovely indeed! Sam, thank you for essential basics. Lol, i can’t even buy stripboard in my country, now i need to decide what i like less - pcb design and etching or making stripboard out of common board.
damn, this gentleman is straight up vince noir AND howard moon in one. what a treat!
Amazing video! I look forward to the series.
Man I imagine that's going to hurt taking that tape off. Looking forward to part 3!
VCO sounds good for stepper motor control. I'll be looking into it.
haha, at around 4:00 your voice over comes on a wee bit louder! BOOOM! thanks for the upload!
This is awesome don't give up on this series :-)
Thank you CEM3340 video 👍
Thanks for posting these videos'!A lot of fun and very informative for those of us that love the smell of solder!
Working on mine now, tried to create pcb board - 65 x 65 mm size - thanks a lot!!
THANK YOU SO MUCH FOR THIS SERIES. I NEEDED THIS SO MUCH.
You’re amazing man thank u. First time I rly felt like yea I can make my own electronic world of sounds eventually
Thank you. Congrats for the content and presentation of your channel in general. Love from Brazil.
World-class presentation! Thanks!
You're the music version of William Osman... except your creations actually work! ... Mostly!
Hatagashira exactly! I've been saying this for years! Well...figuratively. I comment this few month ago because it's so obvious! Some kind od weird colab would be awesome!
Coool video ! Thanks again for doing those, its a great way to get into modular synth !
I'm going to uni soon, and I might give this a go dude. Sick casual tutorial though man
this guy is off the charts
Love your work man.
Wow, this is fantastic. Thanks for sharing. I think I found my next project.
Best soldering video ever!
I would love to learn from you dude. I mean great would be an understatement to describe how awesome a teacher you would be. 😁
you're very generous thank you 🎛🎛🐛 would love to see an audio level input as a modulation source. like mic or drum machine etc.
This is great! Give us the next one in the series!
Oh man. That's exactly the kind of chip I've been looking for. Biiiig thanks for that! I didn't find it or the AS version on eBay yet though.
google "electric druid"
electricdruid.net/product-category/oscillators/
Now there's also one in eBay with the AS3340. Slightly cheaper than Electric Druid
You can also get them form the Erica Synths website
Yeap. Found it as well. I think it was even more expensive there.
MODS: ok so i put another 100k pot in series with the tuner pot, and now i can tune a much wider range; whereas I was able to find middle C and tune to that now. :D, i got the tuning pretty tight now, i can span more than a few octaves and remain in tune :D so pumped I used a BOSS TU-3 on chromatic using middle c and checking in the DAW with another voice layered over top. cheers
You're my engineering hero.
Entertaining and educational. Thanks man 👍🏼
I've been waiting so long for a series like this. No knowledge on electronics whatsoever, but with videos like this I'm willing to try. Got yourself another patreon! What tier gets the additional information of the extra features?
Thank you so much for this video i can't wait to build my own!
want one of these!! great videos by the way, you rule!
This chip is expensive as hell, mate. But the video is awesome! You inspired me to dive into synths world. Thank you!
Check as3340
@@LOOKMUMNOCOMPUTER thank you, Sir! Can you tell, what's the difference between them? I see that as3340 is completely affordable.
Wow I've been searching for a simple straightforward VCO like this for years! This is perfect! Gonna order me a butt-ton of those ICs.
like Get Stuffed but DIY synths- wonderful
You should add a potentiometer to the front to tune it on the go
Thanks for your amazing videos
Great video! Keep up the good work!
Do you ever get your safety pin caught on things. Like when you take your jumper off and stuff.
Absolutely Bravo ! 👍👍👍
Crazy as hell, but dude knows his shit though
Great video! Would love to see an lm13700 vcf.
I love this and want to try making one.
ah beauty - just found this channel. synthesizer love~
That was fun! Thanks.
You're so cool. Thanks for sharing your stuff
Cem prices skyrocketing! 😀😀
check out the AS3340
LOOK MUM NO COMPUTER or the Cool audio V3340
Might be hard to find, the V3340 in DIL package was discontinued (only available in surface mount).
Hey dude.... you are GRREATT ...... a little (well actually a lot) more crazy than me ..... but both of us are doing ELECTRONICS and SYNTHS so I gave you a shout-out on my channel and made yours a FEATURED CHANNEL (even though I am peanuts compared to you) ....... keep up the great vids and I am you fan 🙂
Thanks for inspiration
Your a braniac Sam! genius.
historic and very important
Thanks for all your freaky stuff!
Just found your channel... your videos are so fucking awesome.
