Custom Dummy Load With Data Logging
https://hackaday.com/2021/03/15/custom-dummy-load-with-data-logging/
While it might seem counterintuitive on the surface, there are a number of cases where dumping a large amount of energy into a resistor simply to turn it into heat is necessary to the operation of a circuit. Most of these cases involve testing electronic equipment such as power supplies or radio transmitters and while a simple resistor bank can be used in some situations, this active dummy load is comprised of different internals has some extra features to boot.

Any standard ATX computer PSU. 5V at about 30A on red wire. Button connects across PS_on (pin 14) and ground.
Use a relay or transistor controlled by the MCU to hold PS_on low after the button is released. As soon as PS_on goes high (+5V), it will turn itself off.

Riippuu eniten, mihin tämä tehdään. Tuo fetti on aika herkkä särkymään ylijännitteestä esim. ESD. Tai sitten jos kyseessä on esim. teollisuuskäyttöön tarkoitettu 24VDC syöttöinen laite, joka sallitaan liitettäväksi laajempaan johdinverkkoon niin sen DC porttiin tehdään EMC-testeissä surgetesti, jossa DC porttiin ammutaan +-1kV pulsseja 2:n ohmin syöttöresistanssilla eli DC tulon tulee kestää tästä syntyvä lähes 500A piikki ilman, että laite särkyy. Itse suojaus saadaan toki helposti varistorilla, mutta ne laskee aina vähän enemmän läpi kuin pitäisi, joten perässä tuleva väärinpäinkytkemissuoja tulee olla suuniteltu siten, ettei se rikkoonnu tuossa. Itse olen käyttänyt tuossa 1000V kestävää diodia.

The Kuartlotron -
An RFI-Resistant Hi-Fi No-Feedback Audio Signal Buffer
This buffer uses error correction rather than feedback, allowing it to have amazingly low distortion while being simple, low-noise and nearly as fast as a single transistor! RF noise poses no trouble for it.

Tomi Engdahl says:
are you looking for a log pot or linear? I think log pots are inherently more expensive and less reliable, although this is based on anecdotes from others. My preference is to use a linear pot with resistors across the other side of the pot. I tend to use a 150k pot with an 82k resistor between wiper and ground. This makes the pot near-logarithmic. This means you have a much wider choice of pots and they’ll be less expensive and better value. How to do this is explained here: https://sound-au.com/project01.htm

The Best Protection for your Circuits? eFuse! Here is why they are awesome! EB#48
https://www.youtube.com/watch?v=JOhQ3nsR7xo
In this electronics basics episode we will have a closer look at eFuse ICs. They offer a ton of protection features for a very small price tag. That is why I will show you how I used such an eFuse in my LiPo Supercharger project and how you can use it for pretty much every electronics project. The included protection features are the following: undervoltage, overvoltage, reverse voltage, overcurrent and short circuit current. Let’s get started!

Exploring Op Amp Loading
https://hackaday.com/2021/04/18/exploring-op-amp-loading/
Op amps are generally pretty easy to apply, but there are some practical nonideal behaviors you have to keep in mind. [EEforEveryone] takes a test board with some 2X amplifiers on it and — after some fiddling around with the scope probes — demonstrates the effect of capacitive loading on the output of an op amp. (Video, embedded below.)
