Making Actually Useful Schematics in KiCad

Source: Hack a Day

Article note: The person who has been teaching the only class at UK that does PCB design with undergrads is retiring after this academic year. I'm slightly concerned that it's going to turn into a "Paul can fix it" situation, because I'm a rank amateur at PCB design, but that puts me ahead of almost all the other remaining faculty. It's made me alert to discussions about teaching the topic.

[Andrew Greenberg] has some specific ideas for how open-source hardware hackers could do a better job with their KiCad schematics.

In his work with students at Portland State University, [Andrew] finds his students both reading and creating KiCad schematics, and often these schematics leave a little to be desired.

To help improve the situation he’s compiling a checklist of things to be cognisant of when developing schematics in KiCad, particularly if those schematics are going to be read by others, as is the hope with open-source hardware projects.

In the video and in his checklist he runs us through some of the considerations, covering: visual design best practices; using schematic symbols rather than packages; nominating part values; specific types of circuit gotchas; Design for Test; Design for Fail; electric rule checks (ERC); manufacturer (MFR), part number (MPN), and datasheet annotations for Bill of Materials (BOM); and things to check at the end of a design iteration, including updating the date and version number.

(Side note: in the video he refers to the book The Visual Display of Quantitative Information which we have definitely added to our reading list.)

Have some best practices of your own you would like to see on the checklist? Feel free to add your suggestions!

If you’re interested in KiCad you might like to read about what’s new in version 9 and how to customize your KiCad shortcut keys for productivity.

XBMC 4.0 for the Original Xbox

Source: Hacker News

Article note: This is just fun that folks are maintaining the OG Xbox version. Back in the day I bought a used xbox 90% for XBMC duty, because XBMC was a piece of the future so visible even Microsoft had to change course (...to capture and ruin it).

HP and Dell disable HEVC support built into their laptops’ CPUs

Source: Ars Technica

Article note: How is codec licensing always such a clusterfuck? I remember 20-25 years ago dealing with greyware "Codec Packs" that were maybe not laced with malware just to make basic media playback work on Windows, and somehow the industry keeps doing the same shit. And now there are like 3 patent pools, so it's somehow actually worse. At least it looks like AV1 is becoming the dominant species, and it avoids most of that shit. Plus, this is a "Removed functionality from already shipped product" situation, which is universally dirty.
