Designing a good test rig can make work easier on so many levels. This video shows how to create a test kit for SMD inductors and capacitors intended for the Bode100 throughhole fixture.
Purchasing a cheap switching power supply from AliExpress can backfire - such as when spurious noise pops up on your LeCroy oscilloscope!

Peak Detect is a special acquisition mode which lets oscilloscopes see rarely-occurring "glitches" on large time bases. Let us learn how it works and why it is helpful!
P.S. By and large, this video also applies to the Envelopeur or Peak Channel Hold modes found in Japanese CombiScopes and DSOs.

Making decisions is an important and annoying factor of life, not only in electrical engineering. The Sieve of Schrinner can be used for all decisionmaking aspects where the individual choices, of which there should be many, have little individual merit making them different from one another.
ORDER OF BATTLE
1:10 - The Schrinner process for decisionmaking
2:20 - An example Schrinner run with some added fun
6:00 - Schrinner „regeneration“ if options go missing
