What is this Canadian breaker panel.

I was visiting the west of Canada and my hotel had a breaker panel with these weird pieces of metal on the switches.

"currently" on vaccation

My hotel in Ibiza casualy decided to connect it's mini fridge to power like this. They're not even hiding it. How the hell is that even possible?

Mehdi, my friend sent a picture of this homemade amp. Mind telling me how its made? That's the only picture my friend sent.

I don't think this is to code...

Had a loose outlet in my new rental house, opened it to tighten, only to find this wonderful grounding solution. Surprisingly it passed when I connected my outlet tester.

Most of the outlets here are two prong, so I'm assuming they did this to cheat code and pass a basic outlet test.

Motors can SING!🎶

I was experimenting with PWM frequencies and managed to make this small DC fan motor produce musical notes.
This motor and fan assembly are actually part of a much larger Arduino project I’m currently building, and this was one of the fun side experiments along the way.
I’d love to hear what you think, and if anyone has ideas for making the sound even cleaner or playing more complex melodies, I’m all ears!

If you’re interested in seeing the full project when it’s finished, let me know.

Future for Analog and Digital Electronics

This question is for ElectroBOOM, but curious to know your guys opinions as well. Open for discussion. In short, where do you see Analog Electronics in the near future, as many parts of the industry move towards Digital Electronics?

I have been following ElectroBOOM's channel for a couple of years now and gotten into electronics and electrical engineering because of him. During college, I noticed the move from analog towards digital electronics and programming is quite popular. I'm told that most electronics move to digital and such as it is much easier/simpler compared to analog/discrete components and circuits. They say in the future, most things would move to digital eventually.

I watched a lot of Mehdi's videos, especially his older ones, and know he preferably works with analog/discrete components rather than computer programming. I find myself in the same boat as well, and like to work with discrete ICs, op-amps, comparators, etc. Thus I like to hear your opinion, if analog electronics can still hold up in the industry today. Seeing the rise of technology today, do you think analog would still be seen in the market/industry in the future?

Side tangent here:

I, for one, am not the biggest fan when it comes to code. I just can't seem to find an interest and wrap my head around, which is why I preferably like to work with discrete components, even though it can get too complex. I find it off-putting when I want to design some circuit for a project, and then look online and see that many achieve it just by programming a microcontroller. I like being able to see and assemble a circuit with physical components. That is also why I liked his ElectroBOOM101 series, especially the OpAmp and Transistor Episodes.

Flyback arcs with cactus electrode

I just used a cactus leaf as a electrode and it made those beautiful orange arcs.

HV source was a flyback driven by modified temu ZVS driver (IRFP064N 》IRFP250N) running on 25V 10A max.
