- This is the first module in a series of modules for an analog modular drum machine! It's a simple clock oscillator and you can use the circuit as an audio rate oscillator as well.
Here's a link to the schematic and a zip file with the gerber files for the PCB: www.dropbox.com/scl/fo/4rxf1a...

The narrow pulse can come in handy for triggering lopass gates.
Nice, new video 🎉
Hell yea! I've been looking into this for while. You gotta do clock divider next!
I do have a clock divider in the system and i’ll make a video about it soon as well! But i will first make videos about some of the sound generators so if anyone wants to build these, they can get some sounds out. But after that, the clock divider might be next!
That's brilliant way of using my favorite circuit. Got inspired of it and will probably do something similar as well.
Was thinking that half of the inverters could also be used...well...as an inverter to invert the three clock pulses. Useful to get for instance kick and snare on every other beat.
The 12V pulse may be bit hot for some commercial equipment so maybe the 1k resistor on the output could be moved before the LED so that they form a voltage divider. Then just adjust to liking. Some equipment I've seen use 7V pulses, some 5V and some use something else.
Regarding the pulse width, you could add a potentiometer with swiper connected to output, one end to the rate potentiometer and one end through the diode. This will limit the max frequency a bit and wont give terribly lot of PW control, but some anyway.
Oh yes, it's just a lovely circuit and one can do all kinds of fun with it.
Oh true, i dont know why i didnt concider making 3 clocks with inverted outputs too, that would be handy! I’ve used a potentiometer and a diode as PW control with another 40106 oscillator circuit before! It’s kinda sketchy as it does indeed adjust the pitch, but its a very useful addition concidering how simple it is! 😎
good one
nicely done !!!!
Glad you’re doing this series
From the sound I would say that you are not only syncing the second clock but also over enabling or disabling it. The ON/OFF ratio of the master clock defines the enable vs disable duration of the 2nd clock. So it could be interesting to control the on/off ratio of the master clock. With it you can control the number of 'ratchets', so to speak.
Yeah that’s true! You could add a diode and potentiometer to the oscillator for a crude PW control so you could get different kinds of ratchets
Cool! 👍🏾
Thank you! This video is really inspiring. Getting me back into DIY synth. Do you think this schematic will work with a cd4069 chip? I've got loads left over. Looking forward to the next videos
No sorry, this wont work with a cd4069, because it is a hex inverter. The cd40106 is a hex schmitt trigger ic so they have a different function. You can make square wave oscillators with the 4069 as well, but it is a different circuit! You can find examples of a 4069 oscillator on google!
@@LAURISDIYCHANNELTV oh that's a shame. I'll have to order some 40106 chips! I like the thought of getting the weird synced rhythms with this module.
Yeah it is fun messing around with the sync! Its a useful chip to have anyway!
@@garywallace1938 Luckily the 40106 cheap as chips. The 4069 is very useful IC as well. Probably the most common Twin-T drum circuit can be made with it and it's all over synth schematics else where as well so you can surely get them used up.
@@recyclop4058 thanks, 10x 40106 on order! 👍
I think your microphone gives your voice additional warmth, it sounds good, would you tell me which microphone it is, maybe you made it yourself.
Thanks! Yeah its a mic i built myself! It’s a cheap dynamic capsule i ordered from ebay and the body of the mic is just wood from a local forest lol
Oh and the grill of the mic is a simple tea strainer and theres a microphone windshield inside the strainer around the mic capsule
@@LAURISDIYCHANNELTV ...ok, very imaginative and creative with the tea strainer :) Good things don't always have to be expensive!
Yeah for sure! I got the idea from a comment in one of my microphone videos!
