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

EagleCAD nuances – schematics

Preamble

EagleCAD can have a bit of a steep learning curve, especially for those who have never used a CAD package before. Even if you are familiar with CAD there may be a few finer points that become gotchas after using Eagle for a while…

Note that this article covers schematics only. For board layout issues, see Using EagleCAD – board layout

Messrs. Schmitt, Trigger and APC (and other stories)

Preamble

Just for the hell of it, I wondered if it was possible to substitute the 555 timers in an Atari Punk Console (APC) with some other component, or components.

After seeing some Schmitt-trigger inverters (CD40106) used in oscillator circuits, see Swingers, I thought that I would come up with an alternative design.

555 Noisemusick kit

Preamble

A friend of mine sent me details of the 555 Noisemusick kit, which, while it looks like an Atari Punk Console (APC) – see Atari Punx… -it is essentially two astable multivibrators, with the first providing a CV input to the second, and with additional IR sensors and touch pads.

It is also available as an iOS app, source code is available on github:Noisemusick.
