Re: Weather Stations
Any suggestions for weather stations (a piece of equipment, not an online station) that a linux box can talk to? I assume a serial port is the interface of choice here. The old fashioned way - use wget, curl or perl to rip any data you want off the numerous weather info sites on the net. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Erm, that's not what he wants. He wants to interface with a set of probes outside his home / office / whatever to record whether at his exact location. -- Kirk Strauser In Googlis non est, ergo non est. pgp0.pgp Description: PGP signature

The SitePlayer thing is a matchbox-sized module comprising a NIC chip and a microcontroller which runs a web server enabling you to read and write its I/O ports via a web page. It did unfortunately seem to be the case that you needed a Windoze application to download the HTML code to the SitePlayer module, but OTOH it uses an Ethernet interface so it should be fairly straightforward to use a packet sniffer to see what's going on. -- Pigeon Be kind to pigeons Get my GPG key here: http://pgp.mit.edu:11371/pks/lookup?op=getsearch=0x21C61F7F pgp0.pgp Description: PGP signature

The devices made by http://www.ftdichip.com have support in the Linux kernel which appears to emulate the IOCTLs of a standard serial port, and it seems you can drive an ordinary modem with them. http://www.ftdichip.com/FTDriver.htm#LINUX http://ftdi-usb-sio.sourceforge.net/ (Since on-board serial is slowly going the way of the dinosaur?) ...a situation which I consider to be dead and chewed, as I agree with your Einstein quote from some other thread and reckon that USB is way too complex for anything that doesn't require the high data rate... I build some PIC-microcontroller-based gadget that is controlled by sending it a single character at infrequent intervals; RS232 is ideal, as some PIC microcontrollers have the hardware built in, on those that don't it's trivial to implement it in software, and you can use bell wire for the data cable. USB is way over the top. You can't do it in software on a PIC because they're not fast enough. Even if a PIC with USB hardware was available it'd still need to run rather faster than normal to keep up with the bus. (Fast microcontrollers are scarce and expensive; the requirements are more often for low power consumption and simplicity of interfacing.) The FTDI devices mentioned above do the job, but they are expensive, and are quite likely to cost more than all the other electronic parts put together. Similarly, I consider it to be dead and chewed that digital radio broadcasting is being introduced as a replacement for analogue broadcasting, not as an additional service. I predict that we'll end up seeing a generation of hardware engineers whose proficiency suffers because they were introduced to the subject academically in their teens or later, as opposed to being introduced by natural interest by building crystal sets when they were little. -- Pigeon Be kind to pigeons Get my GPG key here: http://pgp.mit.edu:11371/pks/lookup?op=getsearch=0x21C61F7F pgp0.pgp Description: PGP signature

Re: Weather Stations
Bill: Dallas Semiconductor sold weather stations several years ago that could talk to Linux (as well as that other OS). It was about $80US. I believe that another firm is now marketing the product. A google search ought to find it. The base system includes wind speed and direction, and temperature. There was an add-on for a rain guage too. The software to control it was included.
