PogoPlug Hacking: A Step by Step Guide to Owning The Device

[Films By Kris Hardware] has started quite an interesting YouTube series on hacking and owning a PogoPlug Mobile v4. While this has been done many times in the past, he gives a great step by step tutorial. The series so far is quite impressive, going into great detail on how to gain root access to the device through serial a serial connection.

PogoPlugs are remote-access devices sporting ARM processor running at 800 MHz, which is supported by the Linux Kernel.  The version in question (PogoPlug Mobile v4) have been re-purposed in the past for things like an inexpensive PBX, an OpenWrt router and even a squeezebox replacement. Even if you don’t have a PogoPlug, this could be a great introduction to hacking any Linux-based consumer device.

So far, we’re at part three of what will be an eight-part series, so there’s going to be more to learn if you follow along. His videos have already covered how to connect via a serial port to the device, how to send commands, set the device up, and stop it calling home. This will enable the budding hacker to make the PogoPlug do their bidding. In this age of the cheap single-board Linux computer, hacking this type of device may be going out of style, but the skills you learn here probably won’t any time soon.

Hacking a Pogoplug into a $20 PBX

The Pogoplug Series 4 is a little network attached device that makes your external drives accessible remotely. Under the hood of this device is an ARM processor running at 800 MHz, which is supported by the Linux kernel. If you’re looking to build your own PBX on the cheap, [Ward] runs us through the process. Since the Pogoplug 4 is currently available for about $20, it’s a cheap way to play with telephony.

Step one is to convert the Pogoplug to Debian, which mostly requires following instructions carefully. After the Pogoplug is booting Debian, the Incredible PBX bundle can be installed. We’ve seen this bundle running on a Raspberry Pi in the past. Incredible PBX’s preconfigured setup based on Asterisk and FreePBX gives a ton of functionality out of the box.

With your $20 PBX running, there’s a lot that can be done. Google’s Voice service allows unlimited free calling to the USA and Canada. With Internet connectivity, you get email notifications for voicemails, and can query WolframAlpha by voice.

A Small Replacement for Large Programming Headers

No matter how small you make your embedded projects, you still need a way to program the MCU. Standard programming headers can be annoyingly large for those very small projects. [Danny] wrote in to tell us how we can save room on our PCB designs using special spring loaded connectors, rather than large headers.

There are so many small embedded development systems, such as the Trinket that still rely on standard headers. Reducing the size of the programming headers and interface headers is an issue that deserves more attention than it currently receives. Based on Tag-Connect, a proprietary connector built around pogo-style pins, your PCB does not actually require any on-board mating connector. The PCB footprint simply has test-pads that connect with the pogo-pins and holes that allow for a rock solid connection. While the Tag-Connect header is a bit expensive (it costs about $34), you only need to buy it once.

It would be great to see even smaller Tag-Connect cables. Do you have a similar solution? What about something even smaller and more compact? Write in to tell us about any ultra-compact connector solutions you have been using!

Building an inexpensive Squeezebox client replacement


[Andrew] is a fan of the audio quality provided by the Squeezebox hardware. Like many he was unhappy to hear that the devices were being discontinued, but he figured out a way to build a Squeezebox client clone for less than he could have bought an original.

He set several goals for the build. Most notably he wanted the system to be low-power, noiseless, and to support audio quality of at least 96 kHz at 24 bits. What he came up with is the Pogoplug seen in between the two speakers above. It can be acquired for under $20 and it runs embedded Linux. Another member of the Squeezebox community had been working on a custom distro called SqueezePlug to turn these types of devices into Squeezebox clients. After flashing the distro and tweaking the settings [Andrew] has accomplished his goals. The one caveat is the lack of an audio out port. Above he’s using some cheap USB speakers, but higher-fidelity is possible by choosing a more expensive external USB device.

This will work nicely with that Squeezebox server you built from a Raspberry Pi.

OpenPogo, an alternative to Pogoplug software


Many of us heard the news of Marvell’s SheevaPlug plug-in PC being released alongside its consumer solution counterparts. One of the prominent products based on the SheevaPlug hardware is the Pogoplug. The Pogoplug is essentially a no-configuration media server that allows you to plug in a hard drive and network cable to make data readily available anywhere you have Internet access. It’s a great idea, but the underlying software is closed source, limiting the demographic of the device to consumers who are happy with an out-of-the-box solution. Enter OpenPogo, a solution for people who want a bit more control over their device. OpenPogo gives users more say over what their Pogoplug does; from running a torrent client to a web server to a Ruby on Rails server. The possibilities for the device are limitless, and OpenPogo makes turning our ideas into reality it just that much easier.
