Jamie,

Cool!

If you share your libusb code, please post a link here or on the forums. There are almost certainly others who would like to use the phidgets relay boards with OpenWrt.

Hi Jeff,

Owe you many thanks, this excellent tutorial inspired me to create a wifi-controlled relay using a 520gu and a phidgets relayboard (http://www.phidgets.com/products.php?category=9&product_id=1014).

The phidgets board is extremely pricey for what it is but after examining the cost of printing my own PCB, it didn’t seem that outrageous for a one-off. I had also intended to leverage the API, which has packages on openwrt…

Unfortunately, their API never built right and I ended up writing my own code with libusb…. but that’s another story.

aahhh! all went well, i used your distro on WL500W, works like a dream, now i just have to wait for the CM119 (or 108, whatever it will be) to show up in my mailbox
so far i get to: “No audio_output specified and unable to detect a default audio output device”..
Wireless part is not set up, since the card is missing and also etc/config/wireless file is empty, so i guess it is dissabled that way.
the router works great, it’s a little tricky to set it up since no web server, but for a basic network it is just fine! actualy i didn’t do any editing in etc/config/network, and it works as i type
Flashing was done in a minute (for 1,9 meg file).

Thanks for all the info and keep a good work!

Yes.

Just disable the wireless interface in /etc/config/wireless and set up /etc/config/network according to your needs.

I’m pretty sure the WAN port comes set up to do what you want, try just plugging it in to your network and see what happens. The changes should be pretty minor if you need to make any.

You might need to check the firewall configuration, the assignment of ports to wan/lan, bridging, etc, but it should not be much work.

All of the documentation you need should be available at openwrt.org.

Is there an option to configure it to use LAN instead of WiFi? I have a WL500W with buggy wifi card. two lan ports and wan is OK, system boots and works ok, only without wifi inserted.

I’m using WPA2-personal as my encryption how do I use it with my password?

By: Jeff

Jeff — Thu, 01 Jul 2010 17:28:48 +0000

Once you set a password on the router (using the passwd command) you will no longer be able to telnet into the router, you will have to use ssh with PuTTY or another program.

The dim AIR light is normal.

It is normal for ping to repeat forever. If you press Ctrl-C it should end the command.

For more help try posting on the forums at:
http://mightyohm.com/forum/viewforum.php?f=2

It is much easier for me to answer questions there, and other members of the forums can help as well.

Good luck.

The second issue im facing is before configuring router i was able to telnet via PUTTY into my router. After configuring the router im not able to telnet.
Also the AIR light on my router turned on but it is fade not fully lit.

I have ultimately configured my router on no encryption and i am able to ping some servers but when ping the responce

Hi all,
I will show you how to load the openWrt firmware using windows XP. First of all turn off your windows firewall from control panel and then turnoff the antivirus and its firewall. Now set your router in recovery mode by pressing RESTORE button and turn on the router, the power LED will blink once a second to show this. now select the firmware restoration application provided in cd or download from the asus website.
Put the firmware path in it and then click Upload, wait for sometime and then its done!!
Enjoy XP users

David – Thanks!

Derrick – Glad you got it figured out!

I created a forum for this project over at http://mightyohm.com/forum/viewforum.php?f=2

If you have any other questions, try asking over there – I’m hoping the forums help me answer questions more efficiently (and help other people answer your questions too!).
