Would you believe you can track, and even jam law enforcement radio communications using a pretty pink pager? It turns out the digital radios using the APCO-25 protocol can be jammed using the IM-ME hardware. We’ve seen this ‘toy’ so many times… yet it keeps on surprising us. Or rather, [Travis Goodspeed's] ability to do amazing [...]

[Joby Taffey] takes the prize for the first completed homebrew game for the IM-ME. Over the last few weeks we’ve seen [Travis Goodspeed] working with sprite graphics, and [Emmanuel Roussel] developing game music for the pink pager. But [Joby] didn’t really use either of those. [Travis'] sprites were using a framebuffer that fills up a lot [...]

[Emmanuel Roussel] is coding a version of Tetris for the IM-ME. Before you get too excited, he hasn’t actually written the game yet, but instead started with the familiar theme music. The IM-ME has a piezo speak on board so it’s just a question of frequency and duration. [Emmanuel] developed an Open Office spread sheet [...]

It’s fun to pick apart code, but it gets more difficult when you’re talking about binaries. [Joby Taffey] opened up the secrets to one of [Travis Goodspeed's] hacks by disassembling and sniffing the data from a Zombie Gotcha game binary. We looked in on [Travis'] work yesterday at creating a game using sprites on the IM-ME. He [...]

Here’s a study in sprite animations that [Travis Goodspeed] put together. He’s working with one of his favorites, the pink IM-ME device that he’s been hacking on for a while now. But if you don’t have this hardware that shouldn’t discourage you. There’s a lot to be learned from his methods which will translate to [...]

This circuit board is from the USB dongle of a Girl Tech IM-ME. [Joby Taffey] took it apart and poked around to learn its secrets. These dongles come along with the pink pager that has become a popular low-cost hacking platform. But we haven’t seen much done with the dongle itself up until now. [Joby] used the [...]

A small, cheap spectrum analyzer with an LCD can be a fun thing to play with. But to be truly usefully you need access to raw data, and lots of it. [Travis Goodspeed] set out to make that possible by pulling data with a GoodFET and a Python script. He started with [Michael Ossmann's] IM-ME [...]

[Paul Klemstine] is working on some PC-side software hacks for the IM-ME. We’ve seen a lot of hardware hacks for this device, such as controlling the display, firmware flashing, and using it as a spectrum analyzer, but if you don’t want to alter the device right away you can try [Paul's] collection of hacks. Working [...]

[Michael Ossmann] rolled out some firmware that makes his IM-ME into a Spectrum Analyzer. He met up with [Travis Goodspeed], who authored the IM-ME flashing guide, at SchmooCon and spent some time hacking wireless doo-dads in the hotel bar. Once he arrived home the new firmware was just a few coding sessions away from completion. [...]

[Travis Goodspeed] wrote a guide to firmware flashing for the IM-ME. He’s using a GoodFET open-source JTAG adapter that he designed to do the programming. This is really taking [Dave's] work on the device and running with it.  The end goal being to develop an operating system for the device. If you haven’t read the [...]

[Dave] figured out the command set for the IM-ME terminal. It took a bit of sleuthing to get this pink plastic peripheral to give up these secrets. He used an oscilloscope to sniff out the SPI connections, then used a hacked IM-ME to capture the traffic from a factory-fresh unit. He managed to extrapolate how [...]
