[Alan] pointed out this great commercial paintball sentry gun. The gun has a low power motherboard running Ubuntu connected to a firewire camera. Two high torque motors control the pan and tilt of a Tippman 98 custom. The control box allows for easy setup. You can change the sensitivity, color tracking, and firing modes. It also has a remote kill switch. All around a nice looking machine, but at $3K we doubt many of you will be buying one. Beta test video embedded after the break.

Best Firefox 3 Extensions

We generally try to limit the number of extensions we install for security, performance, and because we use a lot of different systems. That’s not to say there aren’t a lot of interesting addons out there and Mozilla has recently announced the winners of their Extend Firefox 3 Contest. Lifehacker has a full rundown of each of the winners. Nothing really stands out in our eyes (although we might try Last.fm’s toolbar).
The three extensions we always end up installing are Firebug, Greasemonkey, and Flashblock. What are yours?
Waterproof IPod Touch Video Boombox

Popular Mechanics contributor [Anthony Veducci] wanted a virtually indestructible video player that he could use anywhere. Not finding a commercial solution, he decided to build his own. He already had a large waterproof case and another for the iPod Touch. The 8″ display came from an iPod accessory. Unfortunately it was developed before Apple implemented their stupid accessory locking, so he had to use an Apple approved video cable through several adapters to get it to work. The speakers were also salvaged parts. The case was assembled using a jigsaw and a whole lot of epoxy. The speaker openings are covered with latex from a pair of gloves and everything is sealed with silicone. We’re usually trying to escape technology when we head outside, but we’ll be looking back at this the next time we need to ruggedize something.

MySQLgame, Playing With Database Queries

mySQLgame is a quirky App Engine game that has decided to forgo flashy UIs and just stick with the core of the system: a database. You start the game by creating your own row in the shared game database. Game time increments your fuel and money resources every ten seconds. Fuel is spent on scanning other rows and for attacking. Money is used for upgrades and building units. Build up resources and attack your neighbors using database queries, just like any other game. Like a bit more gloss on your internet metagames? Have a look at trolling simulator Forumwarz.

Red Hat Confirms Security Breach

After a week of wondering, Red Hat has confirmed that someone broke in and compromised their security. Although It doesn’t appear the attacker was able to retrieve the passphrase used to sign Fedora packages, the team is switching to new keys. In a separate intrusion the attacker tampered with and signed OpenSSH packages for RHEL. While it’s good to get the full story, no one is happy how long it took Red Hat to release these details.

Kindle Screen Transplant

[blakebevin]’s sister shattered the screen on his Amazon Kindle, so he decided to try replacing it with the screen from a Sony Reader. He disassembled the Sony Reader and used a Dremel to mill down most of the aluminum tabs on the E Ink screen. The screen plugs into the same harness as the original Kindle screen the only problem is fit. The new screen interferes with some of the button movement and without trimming the case will bulge a little. Performance wise the screen ghosts on page turn and [blakebevin] assumes this is due to older technology. We’d hope to never have to do this, but it’s good to know the transplant option is there and not very difficult.
In The Lab: SIM Reader

Adafruit Industries sent us one of their SIM Reader kits a few weeks ago to test. Assembly was a breeze thanks to the through hole components and good documentation. We plugged it into our USB -> RS232 converter and tried out the provided pySimReader software. It worked fine, but our modern SIM card out of an N95 didn’t prove very interesting. It was too new to attempt cloning and being a smart phone it doesn’t rely on the SIM for storing anything unless you specifically tell it to. The story was the same for a SIM we pulled out of a Treo. We tried the device with [Dejan]’s SimScan and a copy of Woron Scan. Both worked without any issue. Conclusion: the device works great despite us lacking anything interesting to do with it.
