Thr power module doesn't work. Instead it makes sparks between the 230V pins. Seller wants me to make a Video about the issue, but I don't want risking to hurt me. Either he don't want to give me some of the money back. I guess, I can send him the module back, but that will cost me more, than it is worth. The other parts seems to be ok.
Works great, but I don't think it'll hit 30k perfectly. I'll try it more and see exactly what it can do.
