The 40106 is great for the first blinky light circuit, it'll bring you your first BEEP generator and you can even go further and make a proper sawtooth core synth VCO from it.
This video is great! Thanks! I just put this together but I used three Schmidt's to make LFOs and Three to make the synth voices, Really wide range of sounds you can get out of it and I really like having the fine tuning control.

Hey! I'm really interested in trying this out! I scrolled down and saw that at one point you had a parts list linked in one of the comments --- but the link doesn't work anymore -- any chance you still have it?
Hi! The parts list is on my website, observerb.com. click on education, and you'll see the 40106 project. Good luck, and let me know how else I can help!
You can! I replace the potentiometer with a rail that goes to 2 4016 chips (there are better chips but that's what I had) and the 4017 cycles through triggering the 8 knobs going through the 4016. I'm working on that vid soon, I'll have the summer to finally do some stuff since I'm a teacher. Look for it soon!
Thanks a bunch! Will be adding more content soon and hopefully gaining some more traction. Been recovering from eye surgery and about to get married so things have been a bit crazy!

@@observerb your website instructions are so easy to follow. You have made them for both the experienced and inexperienced. I can’t wait to order and build!

@observer b... stumbled across this while wondering where to start on a homemade synth....I know just enough about electronics to be dangerous....I'm going to build this with a hc7414 instead of the 40106 because I have a bunch of them in my scrap bin....the 7414 Vcc is only five volts, not 12 like the 40106....I'm going to use the same values for the components as you did for a starting place, but don't know if the different Vcc voltages will effect the divider circuitry on the inputs and outputs of the inverters....or is it all proportional and has nothing to do with Vcc?? I'm going to give it a shot, but would like to have your opinion if you know what the outcome will be....
Not familiar with that chip, but if it works like a Schmitt trigger it should be perfectly fine with a 5v supply and the same components, at least enough to work and then make adjustments because it is proportional like you said. Let me know how it goes!
yes!! just finished it and came back here to compare it you yours....sounds about the same..... I'm amazed at how much (ha ha) "music" I can make by only tuning two pots.... next step after I neaten this up...some kind of sequencer I'm thinkin'.... thanks a lot, I really enjoy your videos...

hi , great work , ive been working with 40106 and i have a question , how do you prevent from not burning your chips when inverted polarization of the current occurs? iv tried to power from a 9v-12 apadter but has burn some of mi components , thank in advance!
Always use a DC power supply, make sure it's not AC. It should handle 12v fine. I always double check every connection before powering it on for testing.
@aaaaa no, maybe a beginner. Wall warts look the same if their output is ac or dc, easily overlooked. I thought they may be using ac when they mentioned an inverted polarization.
@@observerb that makes sense, thank you! Also, I didn't know a capacitor could be used for that, I'm planning on using a voltage divider to generate 2.5V from 5V and ground
@@SP4CEBAR Yeah, the capacitor trick is great for audio stuff! The volume adjustment on mine is just a fancy voltage divider to get the signal level down to an acceptable level.
Hi! Did you've finished that with a voltage ref. IC or with a passive voltage divider? I'm guessing that you've considered a volt. ref. IC too as an obvious option.
Very cheap! You can get the 40106 chip for 1 or 2 dollars. The knobs are probably the most expensive part, and I got the capacitors from scrapping CFL light bulbs. This whole build can be done for about $10.
@@tzoltekaudio yeah, this is about a simple as it gets. The cost of labor, keeping a business, and professional builds would make $300 a reasonable price for a professional boutique hand made drone synth.

I wonder if you could use a 4017 to make a sequencer synth by putting it between the sync and the oscillator.
You can! I replace the potentiometer with a rail that goes to 2 4016 chips (there are better chips but that's what I had) and the 4017 cycles through triggering the 8 knobs going through the 4016.

The classical baby 8 Sequencer was built with the 4017 chip
Is sync the same as a square LFO modulating the volume?
Yup!
Thanks for sharing
Thanks for watching!

You should have a lot more subs than this (107 before my sub).

Towards the output, is that 10nf or 10 uf?
It's uf
@@observerb thank you!!
If you're using a smaller (than 1uF) cap then it gives a hi-pass (RC) filter AFAIK.
It's about the AC coupling, right?
This looks cool. Will it run on 9v? I’ve done the Devil’s Triangle it’s on my channel have a look. Cheers

Well my kitchen grinder can did that too, if I put more carrot in or less I give me that sound, no need ic or any complicated voltage

Hey! Will that circuit work with only 9v? Won't it drain a single 9v battery too fast? Has anyone tried?
It'll totally work with 9v, I made one like that for my guitar player to run through his pedal board. It lasts a good while.
I love the calm background noise of your recording, is it raining outside?
It was the static from the camera audio lol, I've since gotten a better camera and do voice overs with a nice mic.

"Sync" and "Gating" are not the same thing. This is gating, not sync.
It resets the phase, so it's sync, but it does sound more like a gate. It's kinda both!
