ADSR waveform generator


Too rushed for an amusing title…

Here are a number of ADSR circuits, taken from the fantastic Yusynth website (which I came across after reading StackExchange – Building a synthesizer with no prior experience) – in particular the Archives page.

The circuits are described within PDFs, and I drew up the corresponding schematic and board files in EagleCAD.

The EagleCAD files available on github, although seeing as Micro$oft have just acquired Github, they may not be there for very long… Five minutes later – #movingtogitlab!

The EagleCAD files available on Gitlab: Testkins/ADSR-Waveform-generator

Using KiCad


Using KiCad…. for the first time. Here we are using it to create Veroboard/Stripboard layouts – without first laying out the schematic. My reason for this is that I had already used EagleCAD to draw up the schematic, and then, like most people, realised that the board size was too limited, in the freeware version (100 x 80 mm (4″ x 3.2″)), to allow all of the components to be placed.

Note that this article applies to version 4.0.7. Version 5 should be released soon, see When will Kicad 5 be available? – Software – Forums, and should have a much better user experience, as well as being able to import EagleCAD files.

Building Circuits for Stripboard using EAGLE – Mike Perks


This is a great webpage, written by Mike Perks in 2005, which I came across whilst reading Stripboard. Unfortunately, the link therein was dead and it took me a while to locate it. I have taken the liberty to reproduce it here, as it may get lost again, in the sands of time, that is the web. The zip file is here:
