I’ve seen and read the “Logic Noise” articles on Hackaday in the past couple of month. I liked them, and knowing that building the circuits will be lot’s of fun I’m having a go at them all.



In part nine of the series there popped up a section called Part list. That was too much, I now had to go build these for myself. Just before going on summer holiday I ordered all I could find on Ebay and Aliexpress. Returning from holiday I was welcomed by this pretty sight.

Within another week I received the potentiometers and some more chips.


Remembering the times where I couldn’t find parts I knew I had lying around somewhere, I decided to label and store them right away in one of the empty boxes we all have but can’t decide on what to store in them.

One thing that’s missing in the “Logic Noise” series is a link from one article to the next. I keep on searching for articles for lack of a summary page. So here is a summary page with the articles

  1. Logic Noise: Sweet, Sweet Oscillator Sounds

  2. Logic Noise: 8-bits of Glorious Sounds

  3. Logic Noise: The Switching Sequencer Has the Beat

  4. Logic Noise: Sawing Away with Analog Waveforms

  5. Logic Noise: Filters and Drums

  6. Logic Noise: More CMOS Cowbell!

  7. Logic Noise: Sequencing in Silicon

  8. Logic Noise: Taming the Wild Shift Register

  9. Logic Noise: Ping-pong Stereo, Mixers, and More find the partlist for this series halfway through this article

  10. Logic Noise: 4046 Voltage-Controlled Oscillator, Part One

  11. Logic Noise: Playing in Tune with an Exponential VCO

  12.  Logic Noise: Digital to Analog with an R-2R DAC

  13. 32C3: 20 Oscillators in 20 Minutes implausible stand-up comedy
