Awesome! And this device is even cheaper in China (59 RMB, or about 10 USD, including domestic shipping): http://www.dwntme.com/h.Z0L1EYw

Reminds me of these SD cards running Linux

Edit also, there was picture frames at one point with bluetooth that ran linux that were hacked, I made a video years ago, funny to look back on

I've been trying to do this for a while, OpenWRT runs but the performance is sub-optimal, maybe it's just me or my impatience (or I got a flaky device) but it freezes a lot.

it's only about 12 dollars on aliexpress to the US, with most of that being shipping.

You could set up a little mesh network using them. Very cool.

The main issue would be the antenna. Wifi's wavelength is 12cm.

.. which means that a quarter-wave antenna is 3cm, which looks like the metal thing just visible at top right of the PCB extending behind it.

There are loads of devices with tiny WiFi antennae that work fine.

There are very small wifi antennas out there. One of my favorites is a 3mmx4mm cube:http://www.molex.com/molex/products/datasheet.jsp?part=activ...
