Update: more pink wireless-terminal hacking

[Dave] poked around inside of an IM-ME wireless toy and compiled his findings. He read about the device when we covered it in November and picked up a couple to see what he could do. He patched into the debug port in the CC1110 processor and enabled it by performing a chip erase. He then began mapping out how the processor connects and communicates with the qwerty keyboard, the wireless radio, and the LCD screen. The board is full of test points which make the hardware easy to access. [Dave's] experiments show that this hackable device is full of potential so let’s see what you can do!

    What band is the CC1110 on? Both the terminal and USB stick might make for good toys to talk to the CC430 Chronos kit most of us are eagerly waiting for in the mail.

    Excellent news. I picked up one of these myself, but had been intending on bending it to my will using the standard firmware and my own software running on the PC side. I’d be interested to see what Dave turns his into!

    Warning to Readers in Europe: Operation of this device would be illegal in Europe as it uses a frequency band which is used by GSM900 here.

  4. Ben Ryves says:

    kju: The device is sold in the UK and the manual contains UK-specific warranty information, so that seems a bit odd. How can you tell?

  5. subreal says:

    kju: CC1110F32 MCU in this device can also work with 868MHz (legel in EU) so after bit of hacking…

    Could the usb stick be used to sniff GSM traffic then?

    Thought I’d found one in the post xmas blitz of clearance toys. It was a non USB IR. Lame. I want one, but I can’t justify having one mailed. I want to be able to text my seven y/o for supper same as the teenager dammit!

    I love that cheap devices are getting hacked. If you’re reversing something, why not pick something cheap? Same challenge, different price.

    @herro
    this device just shares the same frequency, but uses a really simple radio comm protocol. definitely not gsm sniffing here

  9. GCL says:

    I happen to know that the comms devices used by Pink happen to be made by TI.

  10. ericwertz says:

    @GCL — you’re omniscient. Noone else was able to put TI and the CC1110 together.

    Reminds me so much of the Cybiko of 2005… They were inexpensive and fun to hack, too.

  12. bro says:

    Hmm, can anyone verify what kju said?
    Is this also true for the european version sold by amazon.co.uk ?
    It states at the box uk.girltech.com — so it might be adapted to the uk?

    NL(eu) go one from ebay like $8.
    Now I need some time to hack in to this thing… My friends looked surprised to see me (male 23) with a Pink device. Color and led mod maybe on the way
