i've been reading with some interest folks on this list talking about ibuttons. i went to the ibutton site, but i'm pretty confused. i wonder if anyone has any kind of brief How To with how they intergrated an ibutton in to mh. like what ibutton, how you wire it, what it hooks to, and how mh reads it. For those of us that don't know the first thing about it.. i'd love to know the temperature at certain spots in my house, like for example right next to my computer here - it gets very hot, i could trigger a fan when it reaches a high temp. _________________________________________________________________ Protect your PC - get McAfee.com VirusScan Online http://clinic.mcafee.com/clinic/ibuy/campaign.asp?cid=3963 |

I'm about to place an order for DS18S20 temp sensors and noticed quite a difference in price based on quantity: 1-24 5.04ea 25-49 3.80ea 50-? 2.28ea Maybe as a group, we could order 50+ sensors to enjoy the cost savings. If you are interested, send a message to my email address (not the list) and I'll update the list with the tally. I'm willing to pass the sensors at same cost, you pay for your choice of shipping. -- Keith Webb keith'at'planetwebb'dot'com Cycle Cobb - Promote Cycling in Cobb County |

Here's the easiest way to determine the differences - just click on the 'temperature sensors' link and you can look at the individual spec sheets. The differences are in resolution, how they are powered (parasitic versus a separate power lead), package type. etc. http://www.maxim-ic.com/1-Wire.cfm |

Listmates Just wanted to alert you to another device, the ibutton switch DS2406. It is a remote controlled switch that is supported by misterhouse. Use the set_switch command in iButton:Devices. With this you can put switches anywhere on your iButton network. Actual hardware implementation is simple, requiring the switch, an opto isolator and a relay (with perhaps a driver transistor). I have them operating a blower for my wood stove and am adding temperature control too, since the thermometers are already in place on the 1-wire network. Don Wilde. |

Well that didn't take long! I've received inquiries for over 50 DS18S20's so we have secured the $2.28 price point. It will be several days before I order if anyone else is interested (send your request by mail, not by the mailing list).
