Improving the Motorola Blink Baby Monitor/Camera (Part 3)

So, baby was born, meaning not much time for hacking. Hooray though! Lucas Alexander Gullo, 9/8/2014, 6 lb 9 oz, 19 inches. Hooray!

I haven't had a ton of time to work on things, but there is some progress. Motorola got back to me, though not completely. They've given me a link to a repo with their modified cambozola, which is here: https://github.com/nikhilvs/cambozola-bms I'm still waiting on the source for mjpeg-streamer, and some guidance on the parameters to make the romfs image. I contacted gpl-violations.org and they are also trying to press on the fact that the GPL should have been included since it has embedded linux

I did something kind of interesting hardware wise though. Theory is, wouldn't it be neat to be able to move the camera, say if wife wants to monitor him napping downstairs for a while? So I figured out a way to provide stop-gap portable power for the monitor, so it can be moved around. Best yet, I did it without actually modifying what comes in the box, it all taps onto the exterior. Take a look:

MotorolaBlinkPower

Basically, I got a high current portable USB battery which charges off a micro USB, then made a converter for the power brick it comes with to go to micro USB, and then built a USB to barrel plug cable. Here's my parts list:

Pretty simple solder job, just cut the USB cable in half and strip the wires, bam. I've only tested it briefly, but in about 5 hours on the battery it dropped from 100%->88% so I imagine it'll run for a VERY long time.

Hopefully I'll get to dig through the source a bit more in upcoming weeks, but feel free to use these findings in your own hacking.

Improving the Motorola Blink Baby Monitor/Camera (Part 2)

So, I was able to acquire the actual ROM image for the firmware. Here's a dump of the file structure. I found a few gems:

The contents of /etc/passwd:


root:x:0:0:root:/:/bin/sh
nobody:x:99:99:Nobody:/:/sbin/nologin
ftp:x:501:0:ftp:/var:/bin/sh
usb:x:504:100::/usb:

Also, this appears to be an init script mounting a bunch of things:

Improving the Motorola Blink Baby Monitor/Camera

So we recently purchased the Motorola Blink1 Wifi Baby Monitor (Is this the first blog post acknowledging the baby? He's due any day!) and it's neat hardware with SHIT software. Straight up, it doesn't do most things you would want. I'm working to reverse engineer this and make it workable...particularly on linux.

Before I start...MAD PROPS to Simon Aldrich, whose article laid the foundation to what I'm trying to do here. This got me started: Hacking the Motorola Blink 1 Baby Monitor (Part 1) and Hacking the Motorola Blink 1 Baby Monitor (Part 2)

Movie Theater Room Sound Panels

So we're making a movie theater room and it's set up and going well. The walls need some panels to break up the sound reflection, and rather than do curtains I wanted to do something geeky. I saw some bleach shirt techniques in reddit, but since I got felt for the texture and you can't bleach that, I used white fabric paint. I made 11 canvases, then cut black felt to fit, then traced out the logos on parchment paper, cut them out, ironed them onto the felt, then sprayed the relief pattern on. After painting, I had to wait 72 hours, then washed them, then mounted them to the canvas frames I built.

Take a look! Here's the room all together, see if you can guess the logos!

This is the blank canvas; I ran out of paint for the Matrix one before the first movie in the room.

Using Firefox as a Thin-App for a Specific Web-Site

Objective:

Certain websites were coded to use features and be optimized for Mozilla?s Firefox Browser. These websites utilize strict W3C HTML components which do not render properly in Internet Explorer, or rely heavily on javascript code which runs sluggishly across all versions of Internet Explorer (and impacts the system performance in other applications). Due to the organization?s security policy, the only browser allowed is Internet Explorer. Firefox is specifically disallowed for the following reasons:

  1. Patching ? Firefox updates frequently (every 6 weeks) and as a result keeping it up to date creates support overhead for the various desktop teams.
  2. Management ? Firefox is not natively customizable through Group Policy, and Mozilla?s recommendation is to configure the browser through scripting. This conflicts with our existing management and DSO compliance policies.
  3. Compatibility ? If Firefox becomes the default browser on user machines, it may create compatibility issues with other apps that require Internet Explorer, specifically certain clinical applications.
  4. Testing ? All existing production applications have been tested against the enterprise standard browser. Compounding on previous compatibility concerns, existing production applications may have to undergo testing against an additional production scenario.

Some of the above mentioned concerns are mitigated with a modified installation of Firefox that prevents the user from opening other pages, navigating away from hard-coded URLs, and removing identifying information that the program is actually running inside Firefox. The procedure for creating such a Firefox Thin-App for a web-app is defined below.
