/diy/ - Do It Yourself

>>1863444
Hi anon. I appreciate your humurous concern. Here in the south of Brazil, where winters can be quite cold, we have thermal sheets for our beds. They're somewhat popular, but I don't use them because they heat up the whole bed and I don't need that. I'm warm in my core but legs and feet are cold. So I have opted for a pad targeted at the profissional market, which is used in beauty clinics for reduction in body measures or whatever bullshit. They are smaller and I can position them to just heat up my legs and feet, which is perfect. These can get pretty hot and are made for 10 mins of use on max setting and 40 min on half power setting. Even on lowest setting, they are still too fucking hot to use in bed. So I use a very similar model of pic related. That way I can get the power even lower, and achieve maximum comfy.

I have researched accidents involving thermal sheets and found 0 cases. I think this is because they are made in such a way that when it fails, the circuit opens and it just stops working. We have INMETRO, which is our regulatory institute that certifies products for efficiency and safety before they can be sold. That is probably playing a role in that regard. I have a safety mindset too, and that's why I have mentioned my intention of adding more than one type of fuse in my project, and the use of flame retardant material.
