Almost completed Control Voltage Module for the Synth Project.
The Dual Voltage Control Module for the Synth Project is almost completed. Just need to connect a few more cables, finish the testing of the various units, and install it in the synth rack. The final video on this module will be ready for next week. Get ready, and happy experiments! ... https://www.youtube.com/watch?v=iFySUzoz1Os

Here is the long awaited video on the Complete Volume Control Unit of the Theremin V.2.
All the remaining elements of the Volume Control Unit are described, along with an explanation of how all elements work together. A demo on how the circuit works is presented in the lab section, along with some bonus material.
Happy Experiments!

In this video, we're going to be building an oscilloscope module for our analog synth. If you've watched my previous video, you'll know that I already covered the oscilloscope unit and how it works. In this video, we're going to be putting it all together and seeing how it works.
Enjoy!

Presenting the Sallen-Key filter topology, an easy to design and analyze active filter that can be adapted to work as any kind of filter, from Low Pass, to High Pass and Band Pass.
This video goes through the theory behind this type of filter and shows a design example of a 2nd order low pass filter.
To better understand the contents of this video it is recommended to first view the previous episodes of the series, especially episode 5, first order high pass filters, which introduces the concepts of transfer functions, poles and zeros:

Today we upgrade the synth rack to host the softpot that we introduced last week, and a keyboard.
It is a new shelf that is deep enough to work as a sort of a table. The keyboard, on which we'll work later, sits on the back of this table, while the softpot stands in front of the keyboard, glued to the table thanks to the sticky bottom of the softpot itself.
Here are the links to previous videos that might be useful to better follow this one:

Analog Synthesizer Power Rail Assembly and Installation.
Every module that we will be adding to each shelf of the synthesizer needs, of course, to be powered up. The easiest way to do that is to have one single power supply unit for all the modules at once, or at least on the same shelf. However, there is still the problem with the power distribution and, to solve it, we need some sort of bus that carries the power to all the modules.
This is exactly what I did in this episode. I created a power bus, or power rail, to carry all the necessary voltages for the various modules that will seat on each shelf of the synth. Each module will attach to the closest connector of the rail to extract from it the power it needs.
All the schematics and useful files presented in this video, and any other video of the series, are available as a zip archive on my blog site at the following address:
