[Husstech] wrote in to share his Snake Bot with us. Initially inspired by this post about SickSack, a snake bot, he set out to build his own version. While the concept and even the design aren’t particularly new or groundbreaking, he is very thorough in his documentation. Since this was a project for school, the PDF of his project includes research, schematics, cost breakdowns, and results. We really like the camera and head design, it looks very insect like. You can see a video of the final version being shown off after the break, or you can see an earlier version that is decidedly more phallic.

Building A Snorricam
[youtube=http://www.youtube.com/watch?v=CoZOe3gOkco]
With digital cameras getting cheaper and higher quality, we find ourselves more capable of using them to make videos. A Snorricam can be a very useful tool if you like the effect it produces. This specific design allows for adjustment of the height and angle of the camera allowing for even more possibillities. As you can see in the video after the break, it seems to work pretty well. It might be nice to add some kind of vibration absorbtion though. Anyone got any ideas on that?
Opensource Robotic Arm
[oomlout] has released this Opensource robotic arm. It is 5 axis, using cheap hobby servos. The total cost, including having it cut at thingaiverse.com is roughly $150. The plans include all the pieces, down to the servo controller. This means that you’ll have to supply your own microcontroller and programming. They do state “We can guarantee it is loads of fun to play with, and we think potentially very useful for more serious pursuits.” and we would like to test that guarantee. We’ve been keeping an eye out for this ever since the servo switch assemblies.

Kindle 2 Teardown
The people at iFixit have shown that they’re still on top of their game by tearing down the new Kindle 2 eBook reader. The main processor is a 532MHz ARM-11 from Freescale. Interestly, there isn’t any significant circuitry behind the large keyboard; it seems its existence is just to hide the battery.

OpenVulture, Software For Unmanned Vehicles
The first talk of ShmooCon was [Ethan O’Toole] and [Matt Davis] presenting their OpenVulture software for unmanned vehicles. In the initial stages, they had just planned on building software for Unmanned Aerial Vehicles, but realized that with the proper planning it could be used with any vehicle: airplanes, cars, boats, and subs (or more specifically, their Barbie PowerWheels). The software is in two parts. First is a library that lets you communicate with each of the vehicle’s modules. The second half is the actual navigation software.
They’ve spent a lot of time sourcing hardware modules. They are looking for items that work well, aren’t too expensive, and have a fairly plug and play implementation. For their main processor, they wanted something that wasn’t a microcontroller and could run a full Linux system. The ARM based NSLU2 NAS seems to be the current frontrunner. You can find the opensource software and descriptions of the supported modules on their site.
They’re building the first test UAVs now. One has a 12 foot wingspan for greater lift and stability. We’ve covered the Arduino based Ardupilot and other UAVs in the past.
Debian On The G1 Once Again
[ghostwalker] dropped in on our previous Debian Android post to let us know that he had streamlined the install process. The first time around, it quickly became difficult to complete the process because firmware updates had taken away root access. Hackers have since figured out how to downgrade from RC30 and install BusyBox. All you need to do to put Debian on your phone is download the package from [ghostwalker] and then run the installer script. This isn’t technically a port since Debian already has ARM EABI support. What would you run on your phone if you had access to the entire Debian package tree? A video of Debian starting up is embedded below.
Pandora Dev Unit Unboxed
[skeezix] has got his hands on one of the first Pandora dev kits to make it out the door and took a few photos. This is 1 of the 20 MK2 devboards that were produced. Although, not final it certainly is close to the version they’ll be shipping. Pandora is a Linux based portable game console. The main chip in the clamshell device is a TI OMAP3530. It has OpenGL hardware acceleration and an 800×480 touchscreen. A QWERTY keyboard is included along with analog and digital game controls. WiFi, bluetooth, USB host, TV-out, and dual SDHC card slots round out the package. The team has already presold 4000 devices.
