When I do such projects, I rarely have to limit my budget to 30, 40 bucks because it's ONE PROJECT and the time I spent fussing with a 10 buck less box is blown far too quickly. Something's not being told here. 10 bucks can't be the end of the project?
As to which firmware, you use the one the you are able to work with and fits the router.
Also unclear is how much work you've done in this area. Read http://www.codinghorror.com/blog/2008/08/quantity-always-trumps-quality.html
Now is this you trying to get it right the first time? The perfect device/app by taking the class, notes and thinking you can do this without a lot of practice? You may want to work on this many times to figure it out.
Here's an open source wifi controlled hardware thing -> http://www.team221.com/robotopen/demos.php
So with all that said, maybe what you are doing is just a plug and play thing?
Hi guys, I'm working on a wifi controlled device project, and have some questions I was hoping you could help
me out with.
basically, I have a device that is acting as a web server, that I need to control/communicate with using an
external wireless device(smartphone/tablet). This UI on the external device has to be as robust and lightweight
as possible, running on all wifi devices without having to download an app or anything like that.
The plan I have right now is to hook up a wireless router to the server, and set up a captive portal that
leads to a webpage hosted locally on the server, that acts as the UI in the external device's web browser.
If that is indeed the best solution, I have questions about the setup:
which hardware should I use? It must be less than $40, preferably less than $30. Range is not an issue, in fact
I'd like to contain the range of the signal to less than a few meters, so I'm probably going to use my own
antenna, also must support openWRT or tomato, I've heard bad things about DD-WRT.
Do I need to worry about how much flash/ram the device has? This will not be used to access the internet or
anything major, ONLY to load this one webpage UI from the primary device/server and talk to the primary
So far the following two seem like something I'm after:
the ASUS RT-N10+ is $30 on newegg, and the TP-LINK TL-WR740N is $25 on newegg:
Also, which firmware should I use? Right now I'm in between openWRT and tomato. I think both are capable of
what I want to do, so this mostly depends on which supports the hardware I decide on.
Lastly, which captive portal solution should I use? I don't think I need any authentication or authorization,
any device should be allowed to connect. I started out looking at wifidog, but it seems like that's more than I
need for just redirecting all traffic to the local server's page, and I'd like to avoid having to run a RADIUS.
With this in mind I was considering something like nocatsplash.
Any suggestions at all would be greatly appreciated, thanks for your time.
