Veroboard dimensions

Preamble

Following on from Veroboard and the Sequencer bus described in Sequencer notes, the sequencer bus consists of two separate stripboard designs:

  • The first step, and;
  • The second step (and subsequent)steps), which all use the same board layout.

With respect to the 9T24H (9T25H) board used for the “Second (and subsequent) Step Sequencer Bus v0.9″… as there are 9 of these boards for the 2-10 potentiometer stages for each sequencer (10 step) stage, is it not more economical to combine on one larger board, of n x 9 Tracks?

Likewise, the v0.7 of the First Step Sequence Bus, requires 12T30H, will that not fit multiple times on a larger size board?

ADSR waveform generator

Preamble

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

Preamble

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 – KiCad.info 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

Preamble

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: http://archive.is/download/Pz2iz.zip
