Thanks!

Thanks!🐟

Thanks!

Thanks! You read the description and proceed accordingly. 😉

Thanks!

Hi! It's a "corrosive" rosin that helps to remove oxide from the surfaces that you want to solder together and it also helps with the flow of the molten solder. In German it is probably "flussmittel".

Great practicing!

With a dedicated driver. I explained it in the corresponding long-format video.

What's the problem?

@ beside the feminized EU solder? Nothing I guess.

Does it trigger your manliness or what?

Hi! Sorry, I don't have the dimensions of the case (I guess you mean the spectrometer).

@@CuriousScientist Yes.

Thanks!

Hi! Yes.

oh and also what type of relay you using, it is the low or high triggered?

I don't remember, but it doesn't matter. You can set the GPIO to high or low in the code.

@@CuriousScientist oh okay, thanks!

Hi! Search for "optical bench" on ebay. There will be a seller called "spectrophoton". Check their products.

Thanks!

I'm sorry!

Short attention span and people are generally not interested in science and engineering. 😄 Plus, the algorithm. Whenever I watch shorts, I get served with brainrot content even though I mainly watch tech and science videos.

I don't think u single one getting random contend away from point of interest 😂. To be honest I was impressed, I saw those in many printers/scanners but it never cross my mind to turn it in a spectrometer. I'm inclined to sound, colors annoying me, distortion of reality 😂. U got a sub bud

Thanks! These CCD chips are really cool devices. Since you subbed, you'll hopefully see another, very cool application of them soon.

Yes, I also prefer (and rather use) those. This was just a response video for a viewer.

Useful to have gadget!

There can be many reasons. Did you select the correct COM port and baud rate?

I had to take a few shortcuts due to a lack of free time. 🫠

I am good with this process, thanks!

Hi and thanks! The schematics are not available for this project. The resistors were chosen, so the whole range (more or less) of the ADC is utilized.

Hi! Please refer to the datasheet regarding the exact specifications. I don't know them by heart.

It's a very satisfying process.

I will.

Could work, although the blob on the tip could oxidize easily when it is hot. I prefer doing it one-by-one, if I must. It feels like it results in better joints.

People are messing up their original boards in the exact same way...

Thank you! It's also science and engineering! 😎

Thanks!

Could be. I also encountered 12715 modules, which were actually 12706 based on their voltage and current consumption.

@ thank you for the reply and confirming my suspicions.

It's just a matter of PID tuning. I mentioned in the long-format video that I did not tuned the parameters to perfection, it will be up to those who want to use this or similar setup.

Thanks! You need to open the system_ch32v00x.c file. And there, you have to uncomment the SYSCLK_FREQ_48MHz_HSE 48000000 line and comment the rest. This has been mentioned in my tutorial series, more specifically in my breadboard multimeter video/article. Cheers!

@@CuriousScientist I checked the file and it is already in the 'SYSCLK_FREQ_48MHz_HSE 48000000'-state. Also the IDE greys out all other code in the #defined and #elif defined areas. But it still prints 24000000. I tested it on 3 boards: the blue one from your link, a black one (as showed in your video) and a homemade one with a F4P6 chip. The ChipID changes accordingly, but the SystemClk stays the same 24Mhz... I use MounRiver Studio Version 2.1.0

I also sent an email to MounRiver !

@@CuriousScientist I read to fast. There are 2 48000000 defines. 1 is HSI and the other is HSE. The HSI is working!

It depends on which board you have. HSI works because you probably don't have an external clock source (crystal).

Sure, but it's not public.

Good idea!

@CuriousScientist try to double stack the peltier, it will give better result

Why? This is already a stacked Peltier cooler... Double-stacking it would probably result in worse performance in this specific case.

@@CuriousScientist oh i dont realized u are using the double stack one, thats good then.

It's mentioned and written in the video...

Take care of your eyes! 😄

They are not affected that much since they are more relying on the capillary action.

Same 12 V PSU.

Yes. Although, instead of an oven, I use a hot plate. But the result is the same and it is the same improvement in speed of soldering. I only rely on soldering with and iron when I need to retouch some components.

@@CuriousScientist You can certainly do this with simple circuits, but the reason for the reflow oven is not only to get the board hot and solder everything. It is needed to solder under controlled temperature with an acceptable timing according to the electronic manufacturer's specifications. The reflow oven has a precise temperature sequence with a preheating phase and also cools down after the soldering, so that the components are not exposed to high temperatures for an unnecessarily long time. This cannot be done in such a controlled manner with a heating plate.

I can do it in a very well controlled manner with my hot plate, trust me. I even have forced cooling added so after the last peak, I could provide a fast enough cooling rate so I don't fry the components.

@@CuriousScientist OK 🙂

If you use a 10k potentiometer, you limit the range of the voltage you can achieve on the output. Depending on where you want that range, you can add 0-90 kOhm resistor in series. But I don't recommend this.

Wow, thanks!

I agree!

What do you mean?

Yes, although with a very narrow temperature range.

​@@CuriousScientistI plan to install a peltier water heater in the tank instead of an electric heater.

Let me know how it goes once you have it assembled.

😎

Thank you!

Thanks!

Or more!

Like the solder paste!? 🫠
