Hi, this is Christopher Baum, the founder of Vener8. Working on the pictures. Someone at tabletpc is trigger happy and has banned me from posting (even though I obey all of the rules and Ed keeps reinstating me). However, I wanted to respond to your question immediately. I'd appreciate it if you could put the gist of this message to you in forum. First off, working on the pictures. Second, it's automatic. There is a resistor on the board that does the job of the switch. The prototypes have been working for well over a month without any issues at all. The price includes shipping to anyplace in the United States. We use USPS flat rate. If you have any other questions, please email us at firstname.lastname@example.org. Thanks.
