Synthesized, analog hi-hats are pretty fascinating. That’s because emulating any kind of cymbal using an analog circuit is tough, since the sound a real cymbal produces is not quite pure noise - but also not really harmonic.
Still, a couple classic drum machines like the Roland TR-606 and TR-808 took their best shot at it, with quite strange sounding results that I personally really like. So I decided to follow suit and came up with this simple, but very versatile and crunchy sounding DIY hi-hat circuit. If you want to build along, here's the bill of materials:

I just spent all semester in college learning about filters and amplifiers. It was horribly dull and at times made me want to change my major. But this video showcased such a cool application of these concepts. Seeing how music relates to electrical engineering has been one of the things that’s kept me engaged with EE. Thank you for a job well done.

As I'm planning on a standalone drum module not modular, I've redesigned the PCB's (hope you don't mind) I really enjoy that part of the process. With no pots mounted on the boards and using a tl074 instead of the 2 tl072's I managed to get both drums so far to fit on a single 100mm x 100mm board and should be able to separate them so 50x100 each. Hopefully my layout skills are good enough and they work when the boards arrive. Thanks, for the great work so far, keep them coming.....

really great video. the dissonant square waves at the start actually turned into a cymbal sound at the end of the processing. surprising what just adding together a bunch of pulse waves can do! while trying to figure out how cymbals can be done, i also found out that using XOR gates helps make the sound more "metallic" when used with a lot of square waves with different frequencies XOR gates seem to act as a sort of ring modulator, in a way, while also adding *more* distortion and dissonant frequencies to the sound. might be worth exploring!

I love the trick of 'abusing' the Schmitt trigger VDDs its a very neat solution albeit not always 'predictable' (ie you cant know how different chips will react and the frequency outputs would change by differing amounts from chip to chip, but as the goal is producing noise anyways its a moot point).

@Thats_Mr_Random_Person_to_you Ай бұрын

Ps also first vid I've watched on this channel and 100% new sub! I always like practical examples of filter theory etc that cut away a lot of the day theory and just give useful outputs. Another youtuber (Phil's lab) does a very similar thing with DSPs which is awesome as he talks about the core maths but boils it down to simple code that has practical uses. (Not saying filter theory is pointless, it's not, it's just the maths can get..... difficult quite fast and it's a bit of a rabbit hole where every aspect of that maths isn't always needed to get the end result. Like you don't care about the phase response of any of these filters as you are trying to generate noise, and maniplute said noise, and don't really care about how that noise is altered by the filters. Whereas if you were trying to filter sensor data, it's a bit more complex as the filters do have an impact on the output signals etc...)
