Casper Electronics DIY synth building. Part 1: Oscillators

[@paul2734]

Just the right amount of show and tell, refreshingly instructional and entertaining, thank you.

[@bubagoo]

Thanks!

[@gforsythe1]

This. This is the video I've been hunting for ages as a DIYer. Visual, auditory, intuitive but detailed. Perfect bridge between understanding the guts and just populating a board.

[@bubagoo]

+Glenn Forsythe . Awesome. Thanks. Video 2 coming soon(ish) ;)

[@AntonBurnsRed]

This could be some of the most educational content on electronics I've ever seen! Love the format, love the depth of knowledge, love the show and tell.

[@sameeruddinads]

Probably the best entry point tutorial for all synth DIY noobs !! thank you for this . :)

[@bubagoo]

thanks so much. good to hear

[@Zer0Spinn]

4 years later this comment still stands.

[@bubagoo]

Hey all. The OMSynth is now for sale with kits for all of the videos! Woohoo! noise.kitchen/product-category/bastl/omsynth/

[@pesto12601]

PRICEY!

[@phoenixdk]

This made my day! Incredibly useful, comprehensive enough, and still very simple to follow. Thanks for explaining in some detail how the hex schmitt circuit works, it's amazing!

[@James-zj7zm]

Don't you dare ever stop making these videos. This is amazing.

[@ecarrasco2635]

you reminded me why I love electronics so much, thanks for exploring these musical systems with all of us in such a great way!

[@willynebula6193]

It's 3:30 in the morning and i find your channel now! Why KZbin why!!!

[@saulocisneros]

Two Forty A M here!

[@Kajahzao]

very simple, intuitive and sounds mind blowing kkkk... very hard to find nice beginners material on diy synths, thank you!, im anxious waiting for more !

[@bubagoo]

+Kajahzao thanks!

[@bauhnguefyische667]

Play that funky watermelon white boy! Play that watermelon right! Great Vid, helped make a lot of sense of what you were doing. The erasable pen! Love that, gets the point across much better than some over animated cartoon. What have I got myself into now?

[@lukecurran5572]

Best explanation of oscillator sync I’ve heard. Super helpful. Im trying to build my own synth it’s been a dream of mine for a while. You are going to help me make it happen!

[@danjeans2024]

Hi Casper, thank you for the detailed and inspiring tutorials. One question, since the om synth seems to be no longer available. Is it possible to carry out these tutorials without it and could you give me some advice on what I might need? Many thanks, Dan

[@makeitgreat5542]

dude wtf .... ive been waiting for someone creative enough to help me understand electronics at a waveform sound level. i never connected the dots. been wanting to build my own guitar pedals. ans now i want to build a synth sampler with some who knows weirdness..... thanks keep it up

[@ThaDrones]

Awesome content, very instructionnal and still entertaining though... Great performance at the end! :D

[@slas71]

Haven't had this much fun with electronics in a log while. Thanks for the inspiring and informative clips. My plan is to build a noise-box with lots of LEDs, Switches, Knobs and cables to myself and the kids. This is my first experiments with the CD40106: kzbin.info/www/bejne/o6LbdZtrn8SNbas

[@kuro758]

i checked yours it turned out awesome! did you add to it??

[@EarJuice]

I'm building this atm but without any oscillator for a voltage only Cv to control other modular stuff. So I'm cutting out the oscillator IC. Would I just keep the clock in for the first 4051 chip to get a clock externally? Also I'm not really sure how to modify the sequences. I know where looking at the schematic with the 3 wires going up from the 4051 IC to the 100k resistors. Would I put switches in between the 3 wires or something?

[@coulrophobia7018]

the best laymen explanation about how an oscillator works...i finnally managed to actually get what the components are doeing...tnx :)

[@skyprop]

Now Add A 4 pole voltage controlled Filter, and a Voltage controlled Amplifier And them we be talking business!!!!

[@bordongates221]

This is awesome! I built this, and the sequencer is next- I have all the parts! I am a high school physics teacher, and my students are going to make Atari Punks consoles, then maybe this.

[@bubagoo]

huzzah! thats super cool. I wish i was building weird sound circuits in high school :D Feel free to drop me a line if you have questions or suggestions

[@bordongates221]

@@bubagoo Cool, you replied!!!! Most youtube folks seem to ignore the comments, that's cool that you acknowledged my comment, thanks! I actually found a cool kit and bought 24 of them for my students, at around $4 each. Tech Will Save Us DIY Synth kit, which has everything except the battery- even the speaker! It uses a 556, and one of the circuits is basically the Atari Punk. Ive been building variations of the 40106 synth that you show in your video. There are so many little variations I can do with LDRs and pots, I still have not made it past that. One day I will get to the sequencer and sampler- I have all the parts, but I am still really engaged by building the 40106 oscillator over and over again.

[@hrnekbezucha]

Can't wait for following parts. Yesterday I finished my first oscilator from 4093 and I'm really excited about the whole DIY analog synth thing. Thank you for explaining everything this well, I've learnt so much from this video.

[@KiR_3d]

My 1st experience to make some analog osc. was LM555. This thing is great and can be hot :D Guys'n'girls, are op.amps ideal to build a multiwave osc. with a CV control? I've made some... experimental (not my schem. of course) with TL074. It gives a loud square output but a very low tri/saw output. I can't hear it on my Accord 6AS dynamic (6 ohm) and other (9 ohm) also. P.S. also people mention that it's easier to deal with a bipolar PSU than to fix every DC offset in a circuit. _____ P.P.S. the behavior did changed eventually and it sounds normally now :) no clues

[@trevortjes]

Since I didn't have the amplifier u have in your video (or another amp at all), i tried to do it without. First of all there came no sound whatsoever out of the speaker i plugged directly from the output to ground. Found out that a capacitor between the output and the speaker fixes this. Is that what they call a decoupling capacitor?

[@bubagoo]

Yes that's a decoupling cap ;)

[@roccorossi9969]

+casperelectronics synthesizers what s the capacitor value?

[@SpeccyMan]

Actually that is a DC blocking capacitor. A decoupling capacitor always connects to ground at one end, hence it decouples (usually noise on the power supply rails) to ground. It could technically be called a coupling capacitor (since it couples the output of the oscillator to the input of the amplifier/speaker) but definitely not a decoupling capacitor. A capacitor connected between pins 14 and 7 of your 40106 would be a decoupling capacitor (though not actually necessary here.)

[@bubagoo]

+Nick B ah! Yes! Nick is correct

[@joelroberts1581]

trevortjes which size capacitor did you use or recommend? Thanks

[@RaccoonEatingCacti]

Thank you, These videos really kept me going when I was having a hard time getting things to work. These tutorials helped me understand the logic chips necessary to build a 16 step voltage sequencer; something I thought would always remain unobtainable! Most recently I've been having fun modelling hihats using the CD40106. Four closely tuned Square waves at a relatively high frequency does a good job. Drum machine here I come!

[@bubagoo]

Raccoon Eating Cacti awesome. Glad to hear these videos have helped you keep going with electronics :D

[@HenryGomez]

Hey Casper! I loved your videos so much that I went out and bought the OM Synth for myself to try this! This may be a dumb question - on the right hand side of your bread board, there are red and black wires going from the PCB to the bread board... I'm a little fuzzy about their connection in the middle of the bread boards. Do you have a diagram for this please? Cheers, Henry

[@alessandrocasol9499]

black one is the ground and red the voltage. pur the red one in the red lane and the black in the blue one. basically he’s sharing the same voltage and ground to all the section of the breadboards

[@shaheemvocals]

I really respect the passion you have...Even I wanted to make something just like this but I dont have proper knowledge...

[@simoncardie9371]

How have I missed this? I've been looking up DIY VCO's for ages, yet this never popped up??? It's brilliant, but I'm also 8 years late. Never mind. The technique's the same, but this is so brilliantly explained. Thank you!!!

[@HazeAnderson]

Really now. This is just crimes against watermelons. :(

[@Otm_Shank]

This guy is a friggin genius.

[@teazer999999]

Great demo and explanations. The step oscillator you describe at 17:00 was first described (as far as I know) as "Sound Synthesizer" in Engineer's Notebook: Integrated Circuit Applications (1980) by Forrest Mims III, implemented with a 556 (a dual 555). I like your design with a hex inverter better because you can make 3 with one chip and less discretes (caps and resistors).

[@OmBotCult]

Just got my OMSynth Mini lab version 3.2. I'm in love! So super cool! Thanks Pete!

[@bubagoo]

OmBotCult woohoo! Have fun ;)

[@hulqen]

Great tutorial! Don't miss the crazy melon-synth-sequencer mayhem at the end!

[@SpeccyMan]

It's a melon-atron ;-)

[@inanitas]

How do I know which voltage the capacitors should have?

[@bubagoo]

As a general rule the capacitors should be rated at LEAST 2 times the power supply rating. In this case the supply is 9 volts so the caps are all 18Volts or more. non-polarised caps (like the 1uF caps i use all over the video) are usually high enough that the voltage isn't even written on the package (usually 50volts or more). Electrolytic caps offer much higher capacitance but can have a very low voltage rating. It will almost always be written on the body of the cap. So stick to 18Volts and up and you'll be fine.

[@whiterottenrabbit]

Fucking hackers!

[@OCEANSINSPACE]

These are amazing, any more patching tricks or build ideas? I know you want us to totally experiment I just kinda hit a wall. Cheers and love form MN!

[@MetaMicroLabs]

Dude. It's like you broke into my lab while I was sleeping and shot the video I was putting together. Great job. I'm using a 74HC14 hex-schmitt since I have several on hand for building MIDI-Out and MIDI-Thu circuits. I'll go back to making my lowpass filter build video and met up with you on the flip side. Cheers!

[@bubagoo]

+Meta Micro Ha! looking forward to seeing your video! Everyones got a different approach and there's always more to learn :) Would LOVE to see a simple LPF vid. Filters are almost obligatory for these square wave oscillators.

[@jonstorey3985]

hi there. where can I get that device that you have plugged into your breadboard. thanks jon

[@ArthurKonze]

It's called omsynth and can be bought on his website. But it cost about 90 bucks, which is alot money. I recommend buying some pots with knobs (3 lin, 2 log, all 100k for 5$), a small loudspeaker (3$) and an LM386 (1$) and you get all you need for you first experiments for under 10 bucks.

[@tonigialanze8880]

Thanks for the info Arthur. After reading your comment I am now assuming that I am not hearing any sound (connected to my sound card into Ableton) because I connected everything just to a 9V battery without the LM386 component. I apologise for my noobness, but started following some videos from Look Mum No Computer, and i managed to build and oscillator without any amplifications, thats why I got stuck here. So for the above kind of oscillator an, Amplification of some sort needs to happen so it generates sound?

[@codefrite]

Internet is incredible this days. Here is my journey to your video : - Step 1: I like to do song covers but I am renovating my house and everything is dusty ==> impossible to play my instruments - Step 2: I told to myself, "hey let's buy a midi controller". None really covers my needs (size, functions, number of faders, ...) - Step 3: Ok, let's build a midi controller myself and use it with Ableton - Step 4: Go to smoke some w*** with a guy I know. We talk about random things and ... BANG : He has built one himself - Step 5: He tells me that he wanna build a synth. He wanna me in the project - Step 6: Look for "DIY synth electronic" and I find your vid - Step 7: I have no midi controller and no synth and I can't play my instruments but I am so happy to think that one day I'll be playing on my own gear - Step X: Thank you man for explaining this to random people. I hope than in heaven you'll be in a VIP square playing music on the clouds Cheers from Morocco & Belgium !!!

[@websurfer5772]

~ 4:00 - I got thrown off because it sounds like you're saying "microfarads" (μF) but you're writing (nF) which are nanofarads. I really appreciate you making this video for us. Thank you.

[@KiR_3d]

Hi! I've folowed this video for about 7:30 then I've started to experimenting (already did seen this all but not sure I remember all) It was a surprise: - if I change a resistance of one Schmitt trigger (1-2) then 2nd (3-4) is kind of syncing to the 1st. I've made a simple mixer with one resistor (from pin 2) then it meets the triangle wave from pin 3 and these are mixing with a cool "notchy" wave. - if pin 3 goes to the "meeting point" through a resistor then the wave is completely other! It makes FM on the square wave. Very interesting sound also! I've replaced the R for 2nd schm.osc. to a LDR - it's gives cool performance :) It sounds like RM! One important detail: I have a powerful bycicle headlight for this and... the character of the modulation also depends on it's force! I don't know why... maybe because this headlight gives a "blinking light" (controlled by PWM?), not constant.

[@sound.workshop]

Thank you for making this video. The oscillator sync trick to make the subharmonic series is great. I’m going to use that in this duduk inspired synth im working on

[@dusanvukasovic2525]

It's great to make DIY synth as a standalone device. It's not a product or a brand or a price tag anymore, cool. But if I try imagine the simplest way to get a sound of an analogue oscillator and filter, I end up with an idea of a device with just four CV inputs: pitch, amp, filter cutoff and resonance amt. So I set a DAW to send those values to some, say Arduino, usb interface, that will work as 4 midi cc-to-voltage converters, and that's all. All kinds of LFO -ing, ADSRs, keytracking, velocity scaling, etc. I do from within DAW.

[@joseaurelianosandovalgarci1884]

jjjajajaja.."I dont know what to FF.,,,,,more ...etc"....jajajajja...very well.....i want to try to put another sound over that signal that it comes from your mixer....(added to it) and see if it can be done, ..etc....just an idea

[@Ugfromumantman]

So I keep getting dead spots and what sounds like just little taps. No actual wave length. I hear a little bit of ocillation at the high end of my 100k pot. Wish i had an Oscope to see what my waveform looked like. I can get a few audible frequencies to come through but not much between just dead air and these little tapping noises. Any idea how to remedy this? Im running the signal through an 9v LM386/741 amp circuit i got from Forest Mims' book.

[@moviathan]

i was completely mind fucked when you changed the frequency with just the motion of light. awesome.

[@mtyas]

Great work, I suddenly understand so much more. Thanks a lot

[@Mr.M1STER]

The OMSynth is very expensive. It would be an interesting little project for people to make their own amplifier and speaker circuit. Get a few pots too in order to build and test these oscillators. Great video though, very clear and easy to follow.

[@SABRENOSE]

Man I wish this happened when you were still in Troy! You've really streamlined your modules in the last few years.

[@Vi3chi]

I find it very hard to understand anything. The components aren't clearly visible, even on a big screen and full HD youtube video. There is no instruction how the structure of the omsynth works and I can't even see in which exact holes the components are put in There is no explanation on what signal comes from which hole, or what you have to look out for.

[@Valhallaaaa]

You are our signal man! BIG thank you from Slovakia. I have no words.. This tutorial is perfect! I am new to electronics and i was like i could never do something as this. I was allways afride of " bugs " electronic parts that have more than 2 legs :D But thanks to info from you ill get how it works. Looking up for new videos and wish you all best!!!

[@NicolasKaniak]

why do synths use VCO instead of CCO?

[@HazeAnderson]

Great question! Current is used to push the final output into speakers -- current is hot. High impedance voltage is much easier to work with and more efficient. Think of voltage as communication (audio signal) and current as realization (sound).

[@aham1082]

I want buy that black circuit with potentiometrs and other things. who's can tell me how it is called, what type in search field of Google?

[@NeZversSounds]

Can you show how to make other waveforms? PLEASE!!!

[@bubagoo]

Hey! Ok. It's a lot of info but here you go. Square waves are by far the most convenient wave form to generate for various reasons but.... Yes they can be harsh and/or annoying. Filtering is the easiest way to make them less harsh but they bring their own complications. Anyway try adding a 10k (try higher and lower values) resistor to the square wave output. Then add a 0.1uF cap to ground after the resistor and take your audio out from where the cap and resistor meet. You can also get a triangle wave from the circuit shown in this video but it needs to be buffered meaning you have to run it through a voltage follower before using it. Or even better run it through a lil op amp based inverting amp. The square wave comes from the output of one of the Schmitt triggers in the cd40106 IC. If you take the signal from the INPUT you will get a triangle wave. But as mentioned it needs to be buffered before you can use it.

[@NeZversSounds]

Thanks to your video + one other I found I approximately know how to make midi controlled OSC, but all stuff I found for starters have only about square waves and way to control pulse length. And that's it. Wish there were videos that had like series - from making each waveform (sine, triangle, saw, square/ PWM) than how to expand circuit for OSC to be modular (one option at the time - FM/ am/ rm) Basically as simplified as possible to take total beginners like me into making some modular standalone VCO module. I think it's pretty grate opportunity for electronic minded like you, because as I found there are nothing about it on youtube and seems that demand is quite big looking at view count on this video.

[@AxiisMusic]

Hi, for my Extended Project Qualification in school (An A-level version of a dissertation - A-levels are a British thing) and I plan on building an analogue synth. Is there a way to tune one of these synths to 440Hz like a normal synth and control it from a midi keyboard?

[@mouldeck]

​@@AxiisMusic if you put diodes in the feedback loop you can manage PWM. just 1 diode parallel to the pot will make a pulse generator, and a second one with resistors series to them will make a square with a ratio different than 50%

[@BradsGuitarGarage]

Hey mate, very informative! What's the model of that little scope? I always scoffed at those little things, but seeing one in action, they're actually not too bad for visual cues.

[@SurfDetector]

It is a DSO 138 from JYE Tech Cheers

[@Curtcou]

hey could you give me a hint how the two oscillators interact so they work in steps? i can't figure it out and don't find anything in the interwepz :( thanks a lot for the vid anyway! i have a lot of fun

[@brandonrote2485]

hey man do you sell the black board with the speaker and power supply? Im new to Electrical engineering and have no idea how to make one. please and thank you!

[@dreamyrhodes]

What is a Schmittrigger and how does it differ from other inverters and why do I need a Schmittrigger and not any other inverter here?

[@HazeAnderson]

I am fairly sure the Schmitt trigger is what produces the clean square wave output. It does this via something called hysteresis. If you pay close attention to the first example, Casper shows us first a square wave by tapping the output, and then a triangle wave by tapping the input. If the inverter is just a regular one, you only get the triangle wave and not the square wave.

[@massimookissed1023]

Yeah, it's that hysteresis. The voltage needed at the input to make the output flip state, depends on the output state. As a crude example, the capacitor has to charge up to 3v to make the output flip to 0v, then the capacitor has to discharge to 2v to make the output flip to 5v again. This hysteresis allows stable oscillation. A crude example *_without_* hysteresis: the capacitor charges to 2.5v, the output flips, then the capacitor discharges to barely below 2.5v, and the output flips again. The output keeps flipping so fast it never achieves 0v or 5v, and just ends up as a noisy unpredictable 2.5v. The _□‾ symbol denoting a Schmitt trigger is actually a graph of input (X) vs output (Y).

[@rhampton1914]

I just purchased a Soundmachines Experimental Kit breadboard..it's a complete Kit with components...My question to you is..how do you know where to plug your components in. Do you just choose anywhere?

[@bubagoo]

rhampton1914 I’m pretty sure their kit comes with instructions and example circuits. The bread board is a super great interface for playing with electronics but it’s not especially intuitive at first. There’s countless “how to breadboard” tutorials out there and once you get the basics it’s fast and easy work. Good luck

[@alex_capone]

the demo at the end really sounds like the background music to an NES game

[@Junk_Draw3r]

[@VintageMusicGearTV]

Awesome have made some of your circuits they are great!

[@rickyhong8]

Thank you! Learn so much here!

[@NoyzBot]

I'm looking into picking up a bunch of components to make this kinda stuff. Would it be possible to control all this with CV? I was thinking of getting 3 oscillators (pitch, sync, lfo for maybe LPF) and hooking up everything to my beatstep pro

[@bubagoo]

+NoyzBot Heyo. Yes CV is relatively simple. I hook all the stuff from these videos up to all kinds of analog modular gear. BUT it takes some fancy foot work to make CV interfacing work well. It often requires buffering and scaling of some kind to work in the way most people want. For instance controlling the pitch of an oscillators with CV is simple if you just want a voltage to do something to the pitch. Whatever...just make it go up and down. But if you want to make it scale evenly so you can play chromatic scales and octaves etc then you need a bunch more circuitry. BUT if youre like me and just want to make a bunch of weird connections then I would experiment with vactrols. Home made ones are fine. Just connect the LED to a voltage source and the LDR to part of your circuit you want to control. Heres a pic for making your own 3.bp.blogspot.com/--_a1ArfM9kI/T-ykXgJcKYI/AAAAAAAAABw/PWuAJx0jYWI/s1600/blog+image+3+DIY+vactrol.png .

Hey casper. Im a student of Darsha Hewitt (greetings from her :) ). Im at the moment at the beginning of building some Synthesizer stuff and wanted to ask when the video of the 8 step Synth will be released. Im ordering a lot of stuff at the Moment so it would be helpful to have the "Shopping List" for the next Video too :) Youre Videos are awesome thanks for making them ! :)

[@bubagoo]

+Tim Vischer Thanks! The three episodes will be released a month apart (approx). buy some CD4051 multiplexers, CD4040 binary counters, For the next video we'll use the same chips as well as the ISD1820 voice recorder. For components i try to keep it simple and use 1k, 10k 47k, 100k resistors. AND .01uF, .1uf, 1uf, 10uf, 100uf capacitors. Plus some LEDs. "HI!" back to Darsha :)

[@Kajahzao]

Hay, i wanna to do a project with Arduino and this oscillator, but Arduino just supplies 5V. Is there any turnaround that i may take in order to make the oscillator work ? (like put a extra voltage supplier of 9V )

[@bubagoo]

+KajahzaoNo need to change anything. you can run this oscillator on 5 volts.

I'm wanting to build one. I'm new to the electronics of anything other than guitars. I'm hoping hoping to build a multi-effect keyboard-synth out of a cheap, basic keyboard and using the keys and soundboard...then build a wooden encasement for the keys, knobs and other parts I don't remember the names of. Can these be used to do this? Looking for all the info I can.

great videos man.. 10/10 !

[@Skamanda]

I was looking at Mouser to try and find the CD40106 to make one of these myself, and it turns out there is an entire line of them, many of which say they do different things, and several of which are Schmitt triggers. Is there a specific one on there you can link to that would be the right one for this?

[@bubagoo]

the cheapest one :) But make sure its DIP format not SMD (surface mount)

[@dickheadrecs]

best series on yt

[@Loundre3]

Thanks for showing how to properly use an schmitt trigger oscillator. Beside the CD40106, you could try also using an CD74HC14.
