#1197 DIY Analog Synthesizer (part 1 of 15)

Episode 1197
DIY Analog Synthesizer
Block 1 - output amplifier
Block 2 - noise source
(sorry my white balance was off on the video)

Everyone in the history of synthesizers starts with an oscillator so of course you start with a noise source just to be different. 😏 I approve of this course of action.

[midclock]

The fact about zener diodes generating white noise by the electron flow....well it's magic!

[SeanBZA]

Try a reverse biased transistor base emitter junction as well, as that also will break down around 7V, and give similar noise. You can even use TTL gates for this, abusing the input structures and output structures, with only 2 connections, to get a noise source. For higher more impulsive noise use a RF transistor as amplifier, and connect diode direct to base, without breadboard capacitance, which will reduce that initial falling time a lot.

[Abihef]

Awesome order as well
I've been building oscillators and effects for years and everytime I have a massive struggle hooking it up to something to test the sound😂😂

And then I wanna build a test speaker but before I get started think of another crazy effect and end up with wires everywhere again stretching from breadboards to random amps😂

[L.Lagrange]

I just built the white noise generator and it works great. The only changes are that I used 9v supply, a 2.2k resistor instead of the 18k resistor, and an 8.2v zener instead of a 8.6v zener. It took a little bit of trial and error to find out a good replacement resistor value, but it was still pretty easy. Thanks for the circuit idea

I have a feeling this is going to be a fantastic series of videos.
I've been working on my analogue synth build since Christmas, and with an arduino based midi to CV converter it's now at a point where I can get something vaguely resembling music out of it.
Really looking forward to seeing what you come up with....

Interesting video series idea, looking forward to what’s to come.

[blackarrow]

This is really an amazing idea for a video series! 😍♥

[zilog]

The amount of money you can make selling these has a boutique product is absolutely incredible😮

[Abihef]

You're awesome, this is exactly my cup of tea
The video hasn't started yet but besides this channel being great this is exactly what I've been doing/inventing over the past years. Great fit to my world, exactly what I love and live.

Just started hobby of diy guitar effect pedal builds using veroboard. Really like the simplicity of your videos! Learning alot about opamps!

[rhp]

Awesome and exciting! Can't wait to see how you filter and change the noise source!

[bassblom]

waiting for part 11 where we learn to control the sounds with our brain..

[robinbrowne]

Interesting. A very cool project. Thank you. I love audio projects because they are so much fun to listen to.

[RicardoPenders]

This is going to be very useful for me so thanks a lot for sharing this series of videos, you're the best.

Peter Blasser creator and owner of Ciat Lonbarde uses this technique in his: Tocante Zenert device, Peter Blasser was the Student of Don Buchla, the co inventor of the VCO.
Cool for showing how to create noise with a Zener, once i did a search on that, but nothing found.
I got "alot" of zeners, but not that one.

I can relate to you like everyday I come up with new designs and creative ways to build amplifiers. And sometimes I have dreams about how I would like to build and design amplifier. It is a passion for sure. 🤗💯💖 Thank you for sharing yours 😁 I just love creativity and unique designs think outside the box. Once you understand how amplifiers are built and how solid state chip amps and, op-amps, transistors and so forth work then you can get creative and build your own schematics for building amplifiers different from what's already out there. I tend to keep my schematics to myself though for personal use only. 🤗 But not to say I won't share them and maybe sell some one day but for now it is just for fun.

This could be a start to a digital noise generator I wanted to build.
-Thanks for posting!

[misterretrowolf]

Great video series. Really going to enjoy you doing this! Thanks.
