OpenWrt Turns a $14 Card Reader Into the Smallest Wireless AP ( 43

An anonymous reader writes: The Zsun Wifi card reader is a tiny micro SD card reader with WiFi connectivity. While people managed to access the device's serial console a few months ago, the plan was to eventually run OpenWrt since it's based on the popular Atheros AR9331 WiSoC combined with 64MB RAM and 16MB SPI Flash. A team of Polish hackers have managed this feat, and have now posted instructions to install OpenWrt, as well as other documentation: for example, a description of the board's GPIOs.

    The link for the instructions are: [] The link in the summary is just blogspam.
    • My mind is already boggling with the possibilities, I think I'll be buying a few. I wish I had known about these things sooner than this, but, well, better late than never!

      • will you walk around shopping malls with an open access point with a captive portal that redirects any url requests to a locally stored goatse picture? naughty naughty...

    Cool that they were able to do something extra with this small device. The next step would be having this support a kernel image from the SD card, so the non-hardware hackers amongst us can do other cool stuff. Either way I am curious to know what uses people end up putting it to, beyond the suggested.

  • The ESP8266 microcontroller can act as an access point and a station at the same time. Can be purchased on line in quantity's of 1 for less than $2.00 and is programmable in C/C++. Supports GPIO on its 10 usable GPIO pins and also has an analog input pin. Is compatible with the arduino environment and has a large community at []
  • Im thinking older printers as a way to make them wireless, squeeze some more life from my old HP's.....

    The Carambola 2 [] has the same SoC and runs OpenWrt out of the box.
  • livejournal still exists?

    Just FYI given the main link goes to livejournal vs the original piece on this; progress has been made to use the device's own firmware upgrade method to install openWRT, making this very easy and noob-friendly!

  • The USB gadget support seems to be difficult.
    But if you get it to work, you could e.g., have several encrypted and unencrypted filesystems on the SD-card.

    Give it to someone and let them see a USB flash drive with the unencrypted data, or give them the password to some files.

    Or you could have filesystems, where you can write unencrypted, but not read (from e.g. cameras)

  • I'm wondering how long this could run off a little battery. A totally wireless AP that lasted a while could be useful.

Would you people stop playing these stupid games?!?!?!!!!
