[MLB-WIRELESS] Wireless router temp logger?

[David Ashburner]

Hey, where are you guys buying those DS chips?
I want some!!

If you want to use one wire I compiled up the OWW software a while ago.  
Its here:
   
http://www.melbournewireless.org.au/files/wrt54/Packages/ 
oww_0.81.7_mipsel.ipk

OWW project http://oww.sourceforge.net/
If I remember correctly I didn't build the GUI version the idea bing  
that you ran the OWW Client on a machine with a display.

You know, rather than interfacing a sensor directly to the serial port  
on the router why not do it through a microcontroller?

I use Zilog and Atmel micros and it's a snap to interface to the serial  
port on the WRT. You don't need to worry about level shifting as both  
ends are 3.3V, you can even drive the micro from the WRT power supply.

  mm, Z8F6423 gives you a lot of I/O for $12.84
