I've modified the router. soldered usb and connected to an external hard drive and DS9097 1wire adapter, webcam and other devices. 1-wire bus works well in conjunction with ovfs. Organised by monitoring the temperature. More info http://regul.orionnet.ru.
Experimental means were found GPIO pins responsible for LEDs and buttons router.

Table of GPIO pins:
0 wi-fi LED (blue)
1 power LED (yellow)
6 power LED (green)
7 WAN LED (yellow)
12 WI-FI button (default value - 1)
13,14,15,16 lan port LED (green)
17 WAN LED (green)

I wanted to make 1-wire network via GPIO, but ran into a problem. All GPIO pins give 2.2~2.4V, but 1-wire need at least 2.8V. Soldered a pullup resistor does not change the voltage on GPIO pins. because GPIO pins are connected via a bus voltage converter, the output is zener do not give up the voltage above 2.4 volts (imho).
How to make a pull-up 1-wire bus to 5 volts in this case?

I think you can easily shift the voltage level like with I2C, using just a regular MOSFET (like 2N7000). Page 10 of http://ics.nxp.com/support/documents/in … n97055.pdf shows how to do that.

Dir-615
1. Use GPIO PIN for w1-gpio-custom
2. owserver run over w1-gpio
3. w1-lcd + ds18X20 + ds2408 + ds2406 + ds2405
4. One dir-615 is a server and some dir-615 is a clients over 3g (ssh-tonnel with port forwarding)
5. web-cam connect to dir-615 with 3G modem (ssh tonnet to server for BROWSE VIDEO VIA 3G (not real IP) from REMOTE dir-615
notebook <=wifi=> [LAN] =dir615(server)= [WAN] <= internet == [SSHtonnel]=> [3G modem] =Remote DIR615= WEBCAM
port forwarding:
ssh (Control and configurate remote host)
owserver (w1 remote lan)
mjpg-streamer (video and snapshot from remote webcam)
6. remote host send real sms (balance, gsm signal level and other) via e-mail (free) to my Galaxy Note
...more information and scheme on the site
any questions? :-D
