Wow it's only a $9 device (see below)

Definitely trying this out.

I wonder what the power draw is?

Shame they didn't use microusb connector.

No idea about the trustworthiness of this seller but use the page for general info and lots of photos:

http://www.gearbest.com/memory-cards/pp_246125.html

update: only $9.13 with coupon code GBJANRT and use paypal checkout for safety

There is also a source on aliexpress that is $1 cheaper if you are buying bulk.

I wonder if openWRT gives it wifi-N ability, factory firmware only does wifi-G

It's currently £5 inc. delivery on Amazon.co.uk. This puts it into Raspberry Pi Zero and NodeMCU/ESP8266 territory.

Add to the fact that internally it's not very different to the venerable TP-Link WR-703N and it's possibly a great OpenWRT device to tinker with.

I've used Gearbest in the past. They're ok to order from generally, but their unsubscribe mailing list email link doesn't work and I had trouble ordering from them initially due to delivery address issues at my end.

Both this and the still to be delivered "Black-Swift" are minimal single board computers using the AR9331. It should be similar to the Black-Swift's power specs,

"Power consumption: 120 mA typical (400 MHz CPU frequency, Wi-Fi enabled), 60 mA in energy-saving mode (200 MHz, Wi-Fi disabled), 300 mA max"

This is at 5v so ~1.5w max. If you wanted to use even moderate power USB2 peripherals instead of the SD card reader you'd have to inject external 5v power.

There are also a lot of 'smart wifi plugs' which use the same chipset (although with less RAM), which can be bought for ~$20: http://www.anites.com/2015/01/hacking-kankun-smart-wifi-plug...

Interesting. IS it wrong that my first thought was that they look benign and unobtrusive enough that they could be easily socially engineered into somewhere to start scanning for vulnerabilities... ?

When flashed with the appropriate firmware of course.

This is strange - original blog post is not searchable through google. All I see is pages that point to wiki.hackerspace.pl.

Yeah, a few days ago we noticed that our wiki pages fell off Google and Bing search results. No idea why, and Google Webmaster Tools aren't helpful, either. :(

A few days ago Google changed thier ranking algorithm. My blog was wiped out from 400UU/day to 20UU/d.
