thats a 30 minute thank you

Hi The PCB-s just arrived. Where I can buy the SMD parts for the PCB-s?

Its a 3phase AC motor 😂😂😂 ,,,, which usually know as brushless dc motor 😂😂😂

CAN I USE 100K NSTEAD OF 10K

One of those things that seems obvious after you hear it.

It's your video and your science that is fake Sir😂😂😂😂.. you bought identical mortars as opposed to the generator and electric motor that's used in the so called " fake videos "

Very nice project. Just one question - why not heat up the cold side of peltier with resistor, and simultaneously apply laser to hot side? the balance point in this case is zero voltage. At first, it is easy to detect, and second - you don't need 2 cycles of consequent measurement as you do it now (first with light, second with resistor)?

very good plan❤

Hola para el caso de las vías hay la opción de los metalizados químicos, es algo trabajoso pero funciona. Te dejo un video donde lo explican, creo que combinado ambas técnicas (tu laser y el metalizado de las vías) podríamos tener resultados profesionales en casa. Gracias por el video. czcams.com/video/fA78303EVQo/video.htmlsi=M40ykFqYTw9WOsQj

very efficient and unlaboured explanation. Thank you!

nice one bro but we need an exciting project like a cannon or a tank.(AI included)

Do you think Axial Flux motors would work better?

why do the 000webhost requires certain format for password but when opened in php it doest read special characters

Nice and simple thx

Bro please work on this project hard we need this project very badly❤

Try change resistor used in transistor bising (if burn)

Please 🙏 Link to get the MCP6002 module

Also .. companies lie. There's zero guarantee you'll actually get what the label says, even on big name brands.

Perhaps the second thermal sensor should be on the heatsink. The voltage from the Peltier sensor depends on the thermal difference.

Great idea, i am curious ;-)

What happened to "full power test"?

You really need to learn how to properly draw a schematic, left to right, top to bottom and proper transistor rotation. Its such a simple schematic and hard to read because the way its drawn.

Waow nice sharing 👍

I'm skeptical that the system shown in the video will suffice for measuring my optical power, which won't exceed 5 mW. What alternatives should I explore?

13:23 "The Celtier Pell" 🤣🤣🤣

Consider to measure the speed of the increasing value instead of waiting for equilibrium, this ll give instant value without waiting for it to reach the maximum. To do this you have to plot the speed instead of the max as reference for your calculation

Get a Calibrated Laser Power Meter...

Nice. I don't think you mentioned the temperature you set the iron for, though.

muchas gracias Master saludos desde Cali-Colombia

Very interesting project. I am afraid that the heat dissipation from the Peltier element is different at the edge than in the center. It might be useful to heat the Peltier element in the middle when creating the characteristic curves. I am also afraid that the heating emits an enormous amount of energy into the air. Insulation might be useful. Then only the reflecting laser light is undefined and can be compensated for in the code. I have another idea for a laser meter. Why don't you place a small heating element on the back instead of the heat sink? Then let the microcontroller regulate the heating via PID so that 0V comes out at the Peltie element. This gives you pretty much the exact heat output that the laser puts into the element.

Use reflow oven and the plastic dust or that some dust you have Similar to powder coating There are lot of videos available about how to do powder coating

Very interesting and new project nobody have thought off I like it bro ❤❤

Wow very thorough explanation, you anticipated all my questions. I wonder about some of the new "super dark" black coatings like Action Lab explored... vanta black, I forget the other ones

That's really cool!! Awesome project and great editing!

Why don't you use LDR - light-dependent resistor ? You can claculate the luminosity instade of watt because light is measured in lumen

Una consulta de cuantos watts ese laser de fibra? Varias configuraciones y potencias.

Where can I find 500w transformer modul?

Could someone explain what the last piece of hardware is that is being connected to the JTAG USB Programmer at minute 7:56? Is it a normal USB hub? Great Video!😀

The hole in the heater should be rectangular in shape.

i dont know if u still read these, but does it work if we use mobile data, because we are giving the wifi name and password in the arduino code. can u please tell me...

Thanks, Your project is very interesting, I think that regarding the black paint you need, toner is not a good idea, because it has plastic particles, black glass fusion powder would be better. a big greeting from Argentina

Electroplating is super easy. You can even plate your 3dprints. So for that peltier I would spray it with clear glaze and while it's wet you put it in a sealed container with fine graphite powder and give it a shake. Don't open the container right away. Graphite is very messy, wear a mask and if you do it inside do it in the bathroom, run the hot water in the shower to raise the humidity and this will keep your particles from going all over but in this case since we aren't playing I would take it outside and make sure the coverage is good and then let it dry outside. Start with less powder and add as you need. Wipe your surfaces off with alcohol before application but give the part some good squirts of clear. It should be easy to get a uniform layer on something as flat as that peltier. Don't do the mix your wets and drys together. The 2 mixed together block each other's most valuable properties. One sticky layer and then one matte black conductive layer gives you all the sticky while retaining the high conductivity of the graphite. Plating 3d prints means submerging them in a solution of vinegar, salt , and whatever you want to plate with. Nickel is quite good and you get to find out if those cheap nickel strips you bought are just nickel plated steel or the real deal.

whre can we dl sparkstudio

such an awesome channel! Very creative use of electronics knowledge.

interesting experiment. I'm sure that you finish the project very very welllll

Very interesting! I wonder how comercial testers work. Perhaps a thermocouple junction? I wonder, could you shine the laser on one side of the peltier, have the heater resistor on the other side, and adjust the heater power until the peltier balances and outputs zero volts? Oh also try dusting the surface with the toner powder then heating it with a hot air gun to melt and fuse it to the peltier :D

Thank you so much for this video.

You should probably leave the laser right where it is when you switch to electric heating. The presence of the laser changes the air flow around the heat sink in the random air currents of the room. Or perhaps switch to forced air flow
