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:
Here is the record live stream:
Jump to around 48:00 to see this technique demonstrated:
- 5:00am US Pacific
- 8:00am US Eastern
- 5:30pm India
- 1:00pm CET
- 8:00pm China
- 11:00pm Australia
- This week, I’ll talk about Schematic Library management and @hemalchevli
will show how to convert STEP model to PCB footprint
- We’re trying out Jitsi . It works in a Browser without any extensions. On Android Phones (and maybe iPhones), they’ve got an App.

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:
Thanks so much to Kevin Walseth at Digi-Key for making it happen! ⚡️
Beautiful project from Frank Milburn on element14:
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?
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:
And watch it on YouTube:
It’s useful to have a reference item right next to the schematic you’re working on. This tip shows how to add that in and make sure it doesn’t print with the rest of your schematic.
