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.
Today I learned a little about Python, Jupyter, and Pandas in this video: Data Analysis with Python for Excel Users – Full Course.
Today on 0084 A battery powered 486DX2/66 setup and a 386 motherboard with a fancy BIOS I learned about PicoRC: PicoPSU on Retro Computers and also ATX4VC: ATX Power on Retro Computers.
I learned a lot today in this video: LTspice tutorial – EP4 How to import libraries and component models.
Today I stumbled upon: https://www.jbctools.com/. They have some nice looking kit! JBC was mentioned by Dave Jones in EEVblog #596 – World’s Cheapest Soldering Station – Yihua 936 so I went looking.
Note to self: I was watching EEVblog #378 – Dumpster Diving Teardown Repair and EEVblog #763 – Dumpster Plasma TV Bad Cap Repair and Dave Jones says Nichicon make high quality capacitors. Apparently Panasonic, Nippon Chemi-Con, Rubycon, and Cornell Dubilier are also good.
In his video EEVblog #186 – Soldering Tutorial Part 3 – Surface Mount Dave Jones says to use soldering iron temperature of 300°C to 350°C. He set his hot air gun at 350°C.
He also recommends 4x or 6x magnifications for 0402 SMD and recommends not to use them (or smaller) unless you have to because they can increase manufacturing costs due to being small and fiddly and requiring magnification during soldering. The smaller components can affect yield.
For solder he recommends 0.46mm solder (recommended Multicore brand). And flux. Always use flux.
Also he’s on the record as preferring a chisel tip. In this video he also demoed a thing called a “well tip“, which I have never seen or used before. Apparently good for drag soldering?
While I was researching this post I came across the Hakko Product Lineup, they have some nice looking kit!
p.s. in EEVblog #180 – Soldering Tutorial Part 1 – Tools Dave suggests solder in this order:
The first one with silver in it can be good for some SMT devices. The second one has a more stable melting point. The third is tried and tested but has variable range of melting points.
Note: sn = tin; pb = lead; ag = silver.

This video is part of the New Book Teardown feature of my video blog.
In this video I take a look at Learning the Art of Electronics: A Hands-On Lab Course by Thomas C. Hayes and Paul Horowitz published in 2016. The book has 1,140 pages and is a companion to The Art of Electronics 3rd Edition.
Some notes about things of interest we noticed in the book:
Today I stumbled upon some vintage Dave Jones which made me happy: EEVblog #63 – Microchip PIC vs Atmel AVR. :)
