How to install ssh and ntp on a Linux IPAQ: http://red2.ics.hawaii.edu/documentation/ipaq_ssh_install.html (by Dan Morton). Dan has also written (and I modified) a description of how to back up and restore the IPAQs. See also how to install Linux: Shu's notes, an overall and a detailed (old) description, and my specific (2004) instructions. Also, the hardware design spec, the developer's manual for the IPAQ, a description of the CPU and registers, and a list of the registers in /proc/cpu/registers.

Electrofuel has compact (laptop-sized) Lithium Ion SuperPolymer batteries that can hold 160 Wh (11Ah at 15V) in a unit that weights 1.1Kg or 2.4lbs. See here for purchasing (currently $500). Also, a converter that produces 5V from as little as 6V (for $10).
A study of using the Peltier effect to generate electricity in cold rural areas. Also another, more theoretical study of refrigeration and power generation.
tinyOS and protocols developed at UVA for the berkeley motes.
a list of wireless ad-hoc network protocols.
A Performance Comparison of Multi-Hop Wireless Ad Hoc Network Routing Protocols, a paper by Josh Broch, David A. Maltz, David B. Johnson, Yih-Chun Hu, Jorjeta Jetcheva in Mobile Computing and Networking, 1998. There are also papers on geometric routing by Bose et al, Karp et al., and Lin et al.
A comparison of wireless card power consumption.

These NOAA models provide 12 to 48 hour forecast plots of wind and rainfall. They are available at http://www.nws.noaa.gov/pr/hnl/pages/rsm_page.html.
One-wire sensor technology is available from Dallas Semiconductor and is well described on their web site: www.dallassemiconductor.com, and in particular, their ibutton site: www.ibutton.com. A variety of one-wire instruments and interface units are available from Point-Six: www.pointsix.com. Additional one-wire weather instruments are manufactured by Texas Weather, Inc.: www.texasweather.com. There is also a weather station (wind speed and direction, temperature) produced by AAG for $79.
Ways to convert a serial line to an IR interface: from Dallas Semiconductor, and from Rohm, and a production version from Actisys. Also an explanation of the interaction of Linux, IRDA, and handhelds.
The Basic Stamp has a simple programming language. See also the basicx site. The PIC computer might however be a better choice for the long term. PIC programming can be done from Linux -- the original packet was written by Ralph Metzler. An especially good PIC might be the pic16lc717, which can be run for as little as 45uA at 2.5V, and 10uA in watchdog timer mode.
Reading 1-wire instruments from Linux: description of the technology, and source code in C and Java. Also, Nathan Parker's weather software.
other weather sensors (not one-wire) are available from Fascinating Electronics. Dallas Weather has published an article on building your own one-wire sensor. Someone (who has sold Robert White products) on the weather mailing list also suggested the Max 40 line of sensors could be converted. Also, pointsix has a wireless weather station with a batter operated temperature sensor, microprocessor control, and a 418 MHz. FCC certified radio transmitter.
