There’s the Noise Bell with CD40106

Cmos noise bell

For those interested, a super simple, but effective module, a panel of hyper diversified metalic sounds (hit, snare, bell …) [Noise bell cmos module - sound bender (1)] [Noise bell cmos module - sound bender (2)] Only 2 out of 4 oscillators have a pitch setting (lack of space on this module), the other 2 have a trimmer, but a switch allows you to go from 2 oscillators to 4. the link schematic

SUB with CD4013

CD series sub oscillator

While not entirely in Kosmo format, I thought I’d share something I’ve been working on. It’s a sub oscillator based on some old school CD4000 series CMOS logic - that’s where I read about the CD4026 that Sam used in his googol [ thanks @eric ] counter. This thing will take in a signal and spit out an octave below, with an optional fifth or octave above. Here’s a demo of a prototype: Still a few issues to fix up, but you get the idea. Here’s the schematic - have at it. First o…

Sample & Hold with CD4093

White Noise + Sample & Hold module

here’s mine Kosmo format of a S&H from René Schmitz (with LF398 chip) [white noise + sample and hold module - sound bender (1)] “YASH” S&H : [sample and hold] White Noise : [51386_schmitz_white_noise_gen_circuit_and_stripboard_layout_2] link : https://www.schmitzbits.de/sah.html
