How to Synth DIY part 3 The Passive Ring Modulator

The Passive Ring Modulator

This circuit is a very basic one which is why I have chosen it to be our starting point. It is also quite inexpensive with very easy soldering so it should make a great first time soldering project!

A ring Modulator basically takes two incoming signals and combines them spitting out what results in a modulated version of the original signal. This technique was used to create the famous Dalek voices in DR. Who television series.

It can also be used to beef up synth signals, Warp Drum tones, and distort strings etc. overall just a very useful circuit to have handy.

The Passive Ring Mod doesn’t require a power source so no worries there.

Take a look at the video and Have FUN!!!

How to synth DIY part 2

Now that we have established some basics it is time to take a look at what we are actually going to be doing in this series. I want to start off by giving a list of the Synthrotek Kits we will need in order to complete this series. You can purchase these kits as we go along or all of them upfront (getting them upfront is not a bad idea as we will likely have some live Q&A sessions and it will be nice for you to have the kits ready).

Here are the planned kits that will be involved.

1) Passive Ring Mod Kit (think Dalek voice)

2) 4093 Chaoss Nand kit (drone oscillator)

3) 555 Timer kit (this will be used as an LFO to control delay etc)

4) Dirt Filter 9v kit (distortion and filtering)

5) PT2399 Dev Board kit (this is a digital delay that emulates analog delay chips)

6 Vac Pack (adds CV control to any variable resistance controlled circuit)

7) Plastic Enclosure (this will be what we place all our items into) you are not limited to use just this case, feel free to use more than one case or a larger case if you like.

How to Synth DIY

Here at FluxWithIt.com there is a mind set… If you are not thinking beyond intended operation, then you are limiting yourself. To better illustrate this philosophy as it pertains to the studio. I have decided to take you all with me on down the rabbit whole and into a land where an old guitar pedal is a synth, a simple 555 timer chip is a modulation source, a plain plastic box can become a sample manglers wet dream. Luckily with Sponsor Synthrotek I will be able to help you on your journey to Nerd heaven.

Before we take the blue pill and get to tripped out on bending and circuit melding, Lets gather our thoughts.

First we need to assess just what it is we SHOULD know before attempting any of this.

here are some bullet points of what I feel you should know… and I will help assist you in learning. Continue reading →
