f.i.c.s. - Fonera Internet Controlled Switch (ON/OFF)

I got my first FON router for free a couple of months ago.
First thing i did was flash dd-wrt firmware on it. Since FONera router has gpio pins i decided to use one of those pins to control AC loads or turn a switch ON/OFF remotely.
There's a similar/better way of controlling AC loads - check out dd-wrt wiki..
So i decided to build a small circuit that will turn a switch ON and OFF thru the Router's Web Interface. Now i can turn anything ON/OFF from anywhere in the world.....

Hi, I love your idea.

I have a Fonera 2200 with DD-WRT v24 beta. I've followed all your steps, I have access by SSH, but I can't create a directory in JFFS.

Maybe it's because of the firmware version.

Any ideas/advice would be appreciated.

damn, so many Fonera Mods!! (seriously like hundreds :-O )... anyway, did you get your La Fonera free on there La Fonera Aniversary, revolution day or somthing like that? (i mean me and like the rest of the world got it free on that day) :-P.. anyway, i am using a NICE belkin, wireless Mimo (fastest 1 made :-P), so a 2.4g fonera, is not my cup of tea :-( so i will risk my fonera, and mod the crap out of it, and mabe... just mabe... some day get it running better than my belkin (dought it lol)

WHOA! While I really love your project, I must plead for you to please, PLEASE unplug this device ASAP! As jamesbond mentioned the 2N3055 is not appropriate for this application. It is only rated for 60v, and not for AC. Frankly, I'm surprised the circuit works at all. With a larger load, you run a very real risk of the transistor exploding (no, I'm not kidding).

Take a look at http://www.epanorama.net/circuits/parallel_output.html#mainspower to see how you can build a comparably simple circuit which is worlds safer. In addition to the TRIAC being designed to control AC loads such as yours, using an opto-isolator will keep mains-power out of your FON device, meaning you won't risk electrocution.

You can find other designs on the web which show safe ways of controlling AC using microprocessors, including the use of "solid state relays". The latter is more expensive, but quite straighforward to use (basically it's just the TRIAC and optoisolator pre-built for you). BGMicro sells these for about $10 each. You might find them even cheaper through other surplus vendors.

you are crazy !!!! you need to put a TRIAC not a TRANSISTOR !!!!!!!!!!!!!!!!!!!!!

Very Cool. I could see this being a good replacement for x10.
