Inside a 3000W Water-Cooled Power Supply with @ElectrArc240
I’m always impressed with how much @ElectrArc240 knows about power electronics.

I wish I could make database systems like this!
Hackable Desk Robot
Here’s something fun: Your Next Desk Toy Should Be a Hackable Robot. This “DeskBuddy” is basically a ESP32-C3 Super Mini microcontroller with a 1.3-inch OLED display. I tried to order one, just for fun, but it seems they only ship to India.
Drag soldering SMD parts with a flux pen
This guy demos soldering a TQFP package using a no-clean flux pen and a large(ish) soldering iron tip.
Micron’s PCIe 6.0 SSD Hits Mass Production at 28 GB/s
Via Slashdot today: Micron’s PCIe 6.0 SSD Hits Mass Production at 28 GB/s. This is the first PCIe 6.0 SSD with sequential read speeds up to 28 GB/s and random read performance of 5.5 million IOPS. They note that consumer platforms are not expected to adopt PCIe 6.0 until 2030.
KDE Plasma 6.6 is here
Here is a visual guide to the best desktop in the known universe. I am still back on KDE Plasma 5.27.5 on Debian 12, but look forward to upgrading some time soon…

Silly Job Title: Electron Herder. I am the Electron Herder!
In this video we continue to work our way through Learning the Art of Electronics. In this video we continue with 1L Lab: DC Circuits and make a 10 mA ammeter with our meter movement.
We use the 5V LED we made last weekend to test our ammeter.
We use the Riden RD6006 Bench Power Supply to power our test circuit.
We use the EEVblog BM2257 Digital Multimeter to measure the resistance of our 100 µA meter movement.
We use the Multicomp Pro MP701033 Resistor Decade Box for our 23Ω shunt resistor.
We use the Carpenter Mechanical Pencil to take notes.
We use the Kaisi S-160 45x30cm Repair Mat as our workspace.

How to choose a capacitor
In this video Paul Carlson from Mr Carlson’s Lab tests three different types of capacitor to demonstrate their properties. You need to be careful in audio applications because capacitors can behave like microphones.
Picking low noise resistors
Hans Rosenberg runs us through what we should know about resistor noise and how to avoid it. The bottom line is to avoid carbon composition, thick film, carbon film, and metal oxide film; and prefer thin film, metal film, wirewound (watch inductance), and bulk metal foil (expensive but best).
Today I added wirewound to my spell check.
