Re: [Gumstix-users] Bluetooth range...

[Chuck C. <vap...@gm...>]

     I haven't, but I've long thought about trying to power a gumstix
     setup inductively from next to a 110 or 220v power line.  I think the
     applications for an inductively powered gumstix would be really cool.

Just don't switch the line you are powered from :)

There are lots of opto-isolated relay boards out there. You just need relay=
s
that can handle the voltage/current requirements. Here's one I found:
http://www.ozitronics.com/relay.html (there are several on this page, at
least one that can handle 240v.)
