Today I learned about Embedded Systems with ARM Cortex-M Microcontrollers in Assembly Language and C (Fourth Edition) by Yifeng Zhu while watching Lecture 9: Interrupts on YouTube. The full list of associated lectures are here: Short Lectures.
I learned a lot today in this video: LTspice tutorial – EP4 How to import libraries and component models.
Today I discovered Undocumented LTspice while reading Introduction to LTspice – MIT (PDF).
Today I happened upon this ATTiny85 Quick Reference.
I just wanted this on record to show how insanely good ChatGPT4 is:
I am way behind on my videos for In The Lab With Jay Jay, but it’s not for lack of trying! I’ve recorded the video for project 9 of the Maxitronix 20in1 something like five times now, but I still can’t release it because the circuit will not work as advertised. It’s suppose to be a demo of a monostable multivibrator, which is also known as a one-shot multivibrator, but the circuit isn’t working the way that a monostable multivibrator is supposed to work. I’m still in the process of debugging it. I think the problem is a problem with instructions and not my implementation (the instructions are fairly low quality and unreliable in my experience so far), but I haven’t arrived at the bottom of this one yet. I will continue to try and solve this conundrum tomorrow.

In this video I pull the floppy disk out of the cover of my copy of The SCSI Bus and IDE Interface: Protocols, Applications and Programming (2nd Edition).
I have this wonderful old book The SCSI Bus and IDE Interface: Protocols, Applications and Programming (2nd Edition). It was published in 1997 but is still available for purchase through Amazon.
The book comes with a floppy disk (that’s right: a floppy disk!). I had to buy a USB floppy disk drive to read it. I have made the content from the disk available in a tarball, here: scsi.tgz.
If you just want to read the files, those are here:

Let’s go shopping!
Today I stumbled upon some vintage Dave Jones which made me happy: EEVblog #63 – Microchip PIC vs Atmel AVR. :)
I am reading Make: AVR Programming: Learning to Write Software for Hardware and I found this excellent video: Programming AVR Microcontrollers in C – O’Reilly Webcast available from here: Beyond the Arduino: Programming AVR Microcontrollers in C.
The author’s github page is still operational: https://github.com/hexagon5un/AVR-Programming
Their website littlehacks.org is offline but still available via archive.org: https://web.archive.org/web/20160307235812/http://littlehacks.org/
Also there’s this really cool collection of projects over here: Cornell University ECE 4760 Designing with Microcontrollers Final Projects.
