Don't worry to much, brazilian electronics are generally a mess, amateur level in Europe is a lot more professional, I can tell because I have seen a lot, had to repair a lot of this stuff, if I didn't need too, I wouldn't touch it, the chinese products are 50 years ahead. They can do it and keep up with it, because their home market is so big and strong.
This is just my private opinion.

Fine pics. Silly commentary, and it's a PITA the guy only has a 300 baud modem! The loading was _that_ slow.
I was wondering was the board gassing. Surely not 30 secs from the solder. All that messing stops when it gets up to temprature, doesn't it?

Greetings from Ireland. BTW, I get a lot of spam from Brazil. It all hides behind apnic.net, who have the IPs and give them out to various isps, I gather.
I can run 'whois' under linux on an IP and usually get the registered name. But they're all registered to apnic.net. Apnic just say "F*** off and search with our website!" The website reveals nothing. Are you in a good position to uncover those?
