I hope this isn't too off-topic for the group. If it is, please direct me somewhere else.
I need to get some 1-wire weather instruments mounted away from my house, on a post about 75 ft away. This worries me because of how the system basically becomes an antenna. Nearby lightning strikes would wreak havok back at the bus master. AAG seems to have recognized this problem, as the bus master they ship with their weather station is optically isolated. But I don't know if their bus master is supported by owfs... It's based on a DS2480(B?) chip, which probably means their USB device is really a USB-to-RS232 converter in the first place... So I see several possible solutions: 1) The risk is negligible, and it's not worth worrying about. Does anybody do something like what I'm describing without problems that can testify about it? 2) AAG has it right, is the only game in town, and I need to bite the bullet, give up real USB, and buy AAG's gear. Will one owserver instance talk to both USB and RS232 bus masters and aggregate the results? 3) Maybe it's not difficult to optically isolate a 1-wire bus. Does anybody have a circuit diagram? 4) Last but not least, but probably the most complicated: Are there 1-wire-to-wireless bridge chips/circuits around somewhere? That would prevent me having to bury cable, too, although I'd have to worry about how to power the station... Thanks for any advice...
