Samsung NX300 Camera Hack

Samsung NX300 Camera Hack

 

When you think of rooting a device that lives in your pocket you will probably think of your smart phone. With the new Samsung NX300 Smart Camera you now have more pocket items to root. Lars shared this hack by Georg Lukas about Hacking the Samsung NX300 Camera and also rooting it.

“Experience shows that most firmware images provide an easy way to run a user-provided shell script on boot. This feature is often added by the “software engineers” during development, but it boils down to a local root backdoor. On a camera, the SD card would be a good place to search. Other devices might execute code from an USB flash drive or the built-in hard disk.

Usually, we have to start with the firmware update file (nx300.bin from this 241MB ZIP in our case), run binwalk on it, extract and mount the root file system and have our fun. In this case, however, the source archive from Samsung’s OSS Release Center contains an unpacked root file system tree in TIZEN/project/NX300/image/rootfs, so we just examine that:  make_image.log sounds like somebody forgot to clean up before shipping”

Northrop Grumman X-47B RC Plane Build

 Northrop Grumman X-47B RC Plane Build_9

 

Check out this Northrop Grumman X-47B RC Plane Build by Eric Maglio.

“The internal structural parts were cut by laser from some 1/8″ plywood. They were assembled first, then glued inside the skins during the joining process. Much clamping ensured a tight fit. It was easiest to install the landing gear and doors next, while the model could still be rested inside the molds. All of the hinges are laser cut plywood, and no two are identical. This is because the many complex curves mean that the hinge geometry must be precisly controlled. Each gear door has it’s own small servo, and an Arduino controls the sequence of motions.”

Robot uses Kinect for Mapping

at 5:48 pm. Filed under Complex Hacks, Cool Gadgets

 

Check out this Robot that uses Kinect for Mapping that Sean Anderson, Kirk MacTavish, Daryl Tiong, Aditya Sharma from University of Waterloo built for their 4th year project.

“Current accomplishments:
- Optical Flow using Shi Tomasi Corners
- Visual Odometry using Shi Tomasi and GPU SURF
. . . . Features undergo RANSAC to find inliers (in green)
. . . . Least Squares is used across all inliers to solve for rotation and translation
- Loop closure detection using a dynamic feature library
- Global Network Optimization for loop closure”

Sony Mavica MVC-FD7 Teardown

at 2:58 pm. Filed under Cool Gadgets

 

Dave Jones from the EEVBlog does a Sony Mavica MVC-FD7 Teardown. I remember playing with one of these things in the store when it came out. Can’t remember what they cost but it wasn’t cheap. It is funny to think that it stores pictures on a 3.5 inch floppy drive that only holds 1.44 MB! These days you would be hard pressed to store one or two pictures from a good phone these days in 1.44 MB never mind a real digital camera. If you are thinking that the lag time of a second is too long when snapping pictures today just think of the delay that you would have if you were waiting to store each image to a spinning floppy. All that being said this was still quite an interesting thing since the alternative was developing film. 

It is interesting to see that the optics section of the camera is larger than most compact cameras these days. Even though this type of device wasn’t destined to have a long live the camera internals were built with the typical Sony quality of the day. You can see the CCD sensor at 21:40.

Printable Self Assembling Lamp

 Printable Self Assembling Lamp

 

 This Printable Self Assembling Lamp is an interesting concept. It starts out as a flat sheet and folds up into a box with an overhead light. The light turns on using a touch sensitive area. This is what Ikea needs to implement. :)

“The thing that comes out of the printer (it’s a rather special sort of printer) is a flat multi-layer sandwich of shape-memory polymers (they take care of the actual folding, triggered by heat), thin layers of copper, layers of paper and foam for structure, and double-sided tape to keep it all stuck together.”

Mechanical Ball Clock

at 1:20 pm. Filed under Cool Gadgets

 

Turnvater Janosch has created a fun looking Mechanical Ball Clock. No controller here, this thing is powered by a falling weight.

Via: Laughing Squid

“The clock runs for 12 hours, driven by a weight of 2.5 kg sinking approx. 1 meter during that time..Every minute a marble is lifted up and goes down a marble run with three flipping traps that count marbles for minutes, five-minute-steps and hours.
The timekeeping element is a second-pendulum with a pinwheel escapement.”

TRS Drawbot

at 11:40 pm. Filed under Cool Gadgets

This TRS Drawbot is a simple yet powerful drawing robot. The results look fantastic!

“The servos in your R/C car, plane, boat, or ‘copter are controlled by a stream of electrical pulses sent from the onboard receiver. The length of these pulses tells the servo what angle to turn to. You can connect your R/C receiver to an audio input on your stereo or computer and listen to this control signal directly. Because we have only two channels to work with, we can’t send “pen up” or “pen down” commands to TRS Drawbot, and are thus confined to single- or continuous-line artwork. In practice, this is not as much a limitation as it might seem. “
