At 9:00 AM US PDT today, April 1st, KiCad leader developer Seth Hillbrand will be hosting a KiCad Community meetup video conference on Jisti Meet:

Last week’s meetup was nice to see and talk with other KiCad users. Let’s do it again this week.

This week, I’m happy to answer questions and I’ll be working through designing a KiCad version of the Medtronic OpenVentilator project (http://www.medtronic.com/openventilator 5). You may have heard that Medtronic (a multi-billion $ company) bought the company that cancelled the original gov’t contract 2 for low-cost ventilators in 2015 and then this week released a “kind of” open source version 3 of their current (not low-cost) ventilator.

In reality, they released scans of the schematics and some word documents for bring-up procedures. I’m going to see if we can turn the scans into a set of useful KiCad schematics + board files. This still doesn’t get to what’s needed to actually recreate more of these ventilators but it is a needed first step.

If you are curious about recreating designs from incomplete schematics, reverse engineering in KiCad or just want to hang out and chat, please stop by.

Then at 12:00 PM US PDT, Piotr Esden will livestream KiCad board layout:

Goodies for the Open Hardware Summit

The Open Hardware Summit is next week, March 13th!

Here’s a sneak peak at one of the items that everyone will receive in their conference goodie bags:

Getting to Blinky

Thanks so much to Kevin Walseth at Digi-Key for making it happen! ⚡️

And thanks to our Dan (@tekdemo) for the beautiful “After Dark” PCB art  🦋

I made the curved traces with the “Rounder for Tracks” KiCad plugin from the RF-tools repo:
Here is the GitHub repo with the KiCad design files: pdp7/gtb
If you can’t make it to the Open Hardware Summit, then the design is also available an OSH Park shared project:

Screaming LM386: An Audio Amplifier with PCB Art

Beautiful project from Frank Milburn on element14:

Screaming LM386: An Audio Amplifier with PCB Art

I decided to give PCB art a try and will be basing my attempt on methods described by Andrew Sowa.  Andrew uses Adobe Illustrator for the art work and KiCad for the PCB design.  I will also use KiCad but will use my trusty pre-subscription version of Photoshop for the artwork.  Inkscape is another possibility.  Andrew’s process is described in this video from which my work is derived.  The detail behind many of the steps won’t be described in this post – watch the video for that.

The goal is to take a photograph, painting, etc. and place it on a PCB using the FR4, copper layer, solder mask, and silk screen to make the palette.  My PCB will feature the famous work by Edvard Munch, The Scream which has always fascinated me.  So, how to turn a masterpiece into a PCB facsimile?

Palette

The limited palette is a challenge.  For this exercise the focus will be on the central figure in order to reduce board size (and thus cost) of the experiment.  The OSHPark purple solder mask will hopefully give the dark colors desired.  Andrew also used OSHPark in his example, and helpfully provided a palette which has been modified here to help describe how the layers translate to color and are stacked for conversion in KiCad.

There is a shared project for the board:
