Most Important Skills for Electrical Engineering

Today I watched Most Important Skills for Electrical Engineering.

Stuff I need to learn includes:

He listed some important soft skills which included:

  • Critical thinking
  • Problem solving
  • Communication
  • Opportunity detection
  • Tenacity/high-pain-tolerance

Quake ported to Arduino Nano Matter and Sparkfun Thing Plus Matter Boards

Today I found Quake ported to Arduino Nano Matter and Sparkfun Thing Plus Matter Boards via this article from Hackaday: Quake In 276 KB Of RAM.

The code is on GitHub and there’s a YouTube video with a high-level explanation.

Silly Job Title: Component Wrangler

In this video I add improved debouncing logic to the inaugural Silicon Chip and Jaycar Mini Project: JMP001.

Shout out and thank you to Tim Blythman for developing this project.

You can see Tim’s original code and my updates which improve the debouncing implementation.

In the video I mention that we use the pgmspace.h header from Arduino.

This is the inaugural Mini Project! I introduced the Mini Projects recently. They are developed and published by Silicon Chip magazine, and sponsored by Jaycar Electronics (which is an Austrlaian electronics store, similar to Radio Shack in the USA, hopefully it doesn’t end up suffering the same fate.)

In this project, codenamed JMP001, we develop a USB keyboard which can send interesting and unusual symbols (which aren’t usually available on a keyboard) to a Windows computer using the alt-codes that it supports in a typical codepage.

For this first Mini Project I felt it was important to actually buy my components from Jaycar which I did for roughly eighty Australian dollary doos. Approximately US$50. The parts I ordered were these:

Belatedly I did also search for rubber feet.

There was quite a lot that went into the production of this video, and we accumulated a lot of links. Those are here:

In the end this first project was relatively successful, and we did get it to work fairly well on one of my Windows computers. As for the rest you can find out for youself in the video!
