Your nice comments motivate us to prepare more content. Thank you very much.

The reason why a capacitor can charge quickly is that its internal resistance is very small. But its very small internal resistance also makes it fast discharging. For this reason, capacitors are used to meet instantaneous power demands. The closest product to what you are imagining right now is the lithium ion battery. It stores and releases energy through an electrochemical reaction. Lithium ion batteries have a higher energy density than other types of batteries. This means that a battery of the same size can store more energy, resulting in longer usage times.

@@gsbox2709 one more follow up qn, what if the capacitor could have a material with adjustable resistance, maybe using temperature or pressure to trigger different resistances. so while charging it will have a small resistance, and while discharging, it will have a higher resistance i am sorry if i'm sounding like a kid lol, one reason i'm asking is to add a comment and boost the cool video, and another reason is my just curiousity

@@christophergaspar6520 :) Yes, I understand you. Yes, this idea of fast charging of capacitors is interesting and exciting. If it could be implemented, it could be a revolution. The obstacle may be that capacitors are more expensive than batteries with the addition of such a resistor. Or maybe it could be that the calculations of the circuits designed to act like batteries with an adjustable resistor would become more complex for engineers. But it is still a good idea and its applicability should be investigated.

I used cut profiles, but if you do not have this possibility, you can also use a 200 mm long profile. Only the size will be slightly shorter.

There is a piece that joins the two parts, so super glue works. The belt is not too tight. By the way, what you see is not a drill bit. That's a metric 6 tap.

That is a spiral M6 tap.

Os orifícios no material das placas laterais são úteis para o trabalho que especificou. É possível ajustar as distâncias entre os rolos, instalando as peças de suporte em locais diferentes.

With time, the filaments collect moisture. According to the studies, keeping the filament at 40 degrees for 4 hours is the ideal dehumidification method. You can check this method by weighing the filament before and after heating.

Thanks for your opinion. As we wrote in the previous comments, the products you mentioned in the country we are in are more expensive due to taxes.

I have the same problem as the OP. There are no commercial options in my country and to try and import the item would be way out of my budget.

Thanks for your opinion. The reason we do it this way is that we produce the heater ourselves and spread the heat with the fan.

Hi. That depends on the region that you live in. In the country we are living in, Sunlu Filament Dryer Box costs approximately $100 including taxes. This product costs $30-$35. Besides, the aim of this video is to show how to make this kind of product in your's own at home.

Small design flaw of those premade dryers is the temperature limit. Its too low for nylon filament. And on some models, you cant adjust the temperature

If you manage to scavange multiple parts from old stuff, it's actually worth it and really fun. I got my resistance from a broken heater, a power source from a lost router, some local store hardware and I can fit 2 spools of filament. Added an arduino and now I have temperature and humidity controll.

Hey, yes you can but the heater bed that you will use should comply with the power supply. Check the current drawn by the heater bed and the power supply you are using. But still, i recommend using a small fan for air circulation.
