Greetings All, A few questions before I take the plunge... 1. How far apart can two bluetooth gumstixen (proper plural?) communicate ? 2. Has anyone interfaced a gumstix to line voltage relays/switches (230v) ? Which parts are you using ? Thanks in advance, -Peter Peter Greis Zurich Switzerland __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

I don't know that I've ever tried gumstix to gumstix before, but in a scientific test from a gumstix to my sony ericsson s710a, I got about from the mouth of Gordon's garage to roughly where the chicken coop is, which is probably 8 or 9 meters. > 2.

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. C |

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.) chuck On 1/25/06, Craig Hughes <cr...@gu...> wrote: > > On Jan 25, 2006, at 6:13 AM, Peter Greis wrote: > > > Greetings All, > > > > A few questions before I take the plunge... > > > > 1.

My first exposure to gumstix was a blog post somewhere about a Bluetooth sniffer , powered by gumstix. See www.tomsnetworking.com/Sections-article106-page7.php Best regards, Bryce Ryan |
