RIP Lisa Mammoliti

I heard recently that Lisa Mammoliti died from cancer. I didn’t get a lot of details. Lisa was on the interview panel for my first salaried programming job, and she selected me as one of the three cadets taken that year (2000). I guess I would have to say that I didn’t know her particularly well–she wasn’t a smoker and her desk was on the other side of our floor–but she was cheerful and friendly and very generous with me. She had a reputation as a very capable programmer and when you spoke with her you could kind of tell that she was a humble genius. I am sorry to learn of her passing.

Most Important Skills for Electrical Engineering

Today I watched Most Important Skills for Electrical Engineering.

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.

Demo #2: Resistor Box Banana Plug Modding and Demo | Learning Electronics In The Lab With Jay Jay

In this video I mod a pair of resistor boxes by installing banana plug terminals in place of the lug terminals they came with and then I give a quick demo of them.

In the demo we connect them in both series and parallel and then measure their resistance with my Fluke multimeter.

I mention this video from Dave Jones on the EEVblog: EEVblog #1020 – Is A $7 LCR / Component Tester Any Good? which is where I found out about the RS-201W resistor box which he has. I searched on eBay for RS-201W but what I found for over US$1,000 (inc shipping) was way too expensive: IET Labs RS-201W Wide Range Precision Resistance Substituter.
