I could help with that if you want to! (Eu posso ajudar com isso se vocês quiserem!)

Wow, what a bunch of useful information. I'm really happy of being part of this community. Many thanks to you guys. I've read the topics and also took a look in the @sundberg84 project. Now I'm thinking about make some changes to increase the safety, such as fuses (SSR, termal and normal one to protect against overcurrent) and varistor (to protect agains overvoltage). I already made some changes and also will order a PCB tomorrow. Feeling very optimistic!!

Hi @mr_red, thanks for posting. I already had change this, your advice was nice for me. Safety First! haha.

@mr_red interesting! I will make these changes as soon as possible. I really was not concerned about this as I am now. I am learning a lot since I started these projects! Many Thanks.
