X10 Signal Analyzer

x10

[hb] was having some serious issues with noise in the power line communication of his X10 home automation system. He decided to switch to an all RF module system eliminating the need for power line communication. While trying to improve his reliability he built a data logger. It is constructed out of a LEGO RCX and an X10 universal module. Once the RCX is set to listen it records every time that the module activates. A script is used to tell the universal module to trip at regular intervals. Missing time steps in the RCX’s log relate to missed commands. If you’re interested in home automation you should check our previous story and its comments.

Hackaday Links

I usually don’t link to MAKE:Blog because I assume everyone is already reading it (you should). I just thought the GPS tracking link today deserved special attention.

We’ve been talking about “guerrilla drive-ins”. Dirk put together an FM transmitter kit this weekend that would probably work well. He’s also got a nice picture of why you shouldn’t keep your Replay-TV at a construction site.

[Spazz] put together a Hack-A-Day RSS Konfabulator widget.

[jeffers] pointed me to the Bluetooth car whispering article over on Autoblog. I had shrugged it off earlier in the day because I knew it was possible. I didn’t realize they had released the POC software on their site. This is another gem to come out of What The Hack. Here is the pdf of their slides and the torrent link for the video (370MB).

[TILT-MODE-ARMY] claims to have a working HTTP server on a PSP. They’re doing a stress test, but I’m not going to hot link it for fear of melting the little guy.

[Geoff] wrote to inform me that Weta Digital is expanding their render farm with 250 Dual Xenon blades.

DS Trojan

It looks like the DS trojan bricker is in the wild. There are instructions up to fix the situation. I was contacted by DarkFader last week wondering if I’d be interested in his answer to the PSP’s malware that had been circulating. I’m not interested in this kind of hacking because I feel it takes a lot more finesse NOT to break something. Here’s the info straight from the source for those interested:

FIVE teams have completed the Grand Challenge 2005. Only four were able to get through the 131.6 mile course in the 10 hours needed to claim the prize. The fastest was Stanford’s “Stanley” at 6:53:58.

NASA is testing an unmanned sailplane that will turn off its engine once it has found a thermal.

[sprocket] documents the disassembly of the Roboraptor. UPDATE: This is [Sprocket]’s site. The other link was the inspiration.

The XBox 360s that were featured in all of those lewd photographs were apparently stolen property. I was looking for those pics the other day because I’ve decided I need to buy a 360 (you know
