Making Cooler/Generator with Thermoelectric Device

He can talk about the benefits of the sponsors products/services as much as he wants but what sells me is the falling confetti

Someone needs to give him a noble award for the invention of the wife unit

The fact he still has all of his fingers always amazes me.

I just thought I’d mention, TEC coolers are widely used within astrophotography for cooling camera sensors down to reduce thermal noise. It’s really common and they’re great. The main issue that’s showcased here, is the fact they cool really quickly, which can be a problem with icing over a sensor window.

Linus tech tips posts a video "Bad cooling ideas" and features peltier devices. I watch the video and go "huh, wonder how these things work". Literally 5 seconds after that - notification from electroBOOM, new video :D

In all my years of carpentry I have NEVER seen anyone using a jigsaw while sitting

Mehdi: clumsily spends half a day cutting holes into wood to mount heatsinks into. Also Mehdi: has 3d printer on back shelf.

My axiety goes through the roof whenever i see him handling cutting tools in an uncomfortable way. I’m about to have a heart attack

On an atomic level, temperature is created by the atomic structure vibrating. This vibration is caused by all particles in the material vibrating with electromagnetic and nuclear forces. This phenomenon is most visible when atoms slow down their "spin", or internal energy, the closer they reach absolute zero. Since there are two materials with different thermodynamic properties but similar electromagnetic properties, the electrons can be shared easily between the two materials while still maintaining two different specific heat capacities. Once an voltage is applied to the two materials the electrons can flow to the material that they are attracted to. This will cause the vibrating electrons to leave one material the void of the electrons while the other material gains the vibrating electrons. This lack of vibrating electrons is what causes the electron deficient material to drop in temperature while the electron rich material has many vibrating electrons on it increasing its temperature. This is why changing the voltage will cause the electrons to travel to the opposite material but having the same phenomenon. The difference in voltage between the two materials creates a difference between the electron density between the two materials which then causes a difference in the thermal reservoirs between the two materials. This temperature drop is what allows heat to travel across the materials and electrons do not carry any of the heat themselves.

Med holding any sharp devices Me: This can't be good.

I did the crash course in peltier units too haha. I had a small water cooled compressor and used a 8 peltier blocks with individual fans an a aluminium block milled to carry the water through an chill it. Turned out pretty neat. I used a 15 am buck down for my supply and found the most efficient supply an it worked fabulous.

This one's for me. So the Seeback and Peltier effect works in the same way as a solar panel is like an LED. Heat is typically radiated using photons, which are emitted by any object of a certain temperature (blackbody radiation). As heat is just an amount of kinetic energy, the photons give energy to electrons, causing them to drift. The electrons, now higher energy, have a velocity. The voltage potential then counteracts this velocity, resulting in the momentum of the electron being transferred to the other conductors atoms, and the energy is absorbed by the other conductor, causing one to cool down and the other to heat up.

This is my favorite gaming channel.

Thanks Mehdi, I always wondered about those things. Now I don't have to order them from Amazon and spend a week finding out. Love your videos and effort you put into them. Please keep them coming 😁

I am working on thermoelectric generator as temperature sensor in my PhD of materials engineering... You are awesome Mr Mehdi

He actually has a surprisingly accurate idea of what minecraft is

Your "Wife unit" explanation was amazing dude! hahahaha! <3

Thanks for this demonstration it was really informational
