Some things are transparent, and some things are not. Why!? And let’s not even talk about mirrors!

Why Almost Everything Is Actually a Spring
I have a lot of mathematics to learn!
Full 11kV Termination on a steel wire armoured 3 core cable
I love stuff like this where you get to see how industrial cabling is installed.
One ROM 40 – 16-Bit ROM Replacement for Amiga and Beyond
The latest One ROM installment from Piers Rocks. He made his own PIO/DMA emulator and One ROM logic analyzer, as one does.
Inside a 3000W Water-Cooled Power Supply with @ElectrArc240
I’m always impressed with how much @ElectrArc240 knows about power electronics.
The Genius of Old Tools
I wish I could make database systems like this!
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.

Silly Job Title: 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.
