[Tixlegeek] used a Motorola 68HC705J1 development board to remotely control his home through his cellphone. The video above, as well as [Tixlegeek]’s website, is in French, though the video has been captioned. The development board (called the ERMES125) is controlled by a PIC externally. It has an array of LEDs, and apperantly a few high voltage relays. The PIC is connected to a laptop through a serial interface. The laptop is running a small web server, which uses CGI to control the PIC from a webpage. This system allows [Tixlegeek] to log onto the webpage from his web enabled phone, click a few buttons, and have appliances turn on or off through relays controlled by the PIC (via serial signals from the laptop).

Firefox Master Password Recovery Tool
It’s great in this day and age that browsers can remember our passwords for us, allowing us cross-site security without the hassle of memorizing a million different random passwords. It’s great, that is, until we forget our master password. Fret not, though; there is a solution. The folks over at Lifehacker show us how to use FireMaster to recover forgotten or misplaced Firefox master passwords. Perhaps a better solution is to just store those tricky passwords where nobody will find them.
Update: Foundation PC Cooling
[gigs], whose foundation-based PC cooling project we covered earlier, has posted his initial test results. There was a large debate going back and forth in the comments as to whether or not this would work, and hopefully this should clear most of it up. He used a 150W fish tank heater to simulated his system’s heat output, and used a quiet fish tank pump to keep the water flowing. Over 8 hours, he was able to maintain a constant temperature 16° C (61° F). While not quite frigid, this would definitely provide ample cooling for normal operation with some headroom for overclocking.
Chart of results after the jump.

Foundation Cooling
Overclockers are always trying to come up with new, colder, and quieter ways to keep their PCs cool. [gigs] was so dedicated to this, he decided to lay 6 meters of copper pipe to use as a radiator in his new house’s foundation. As of now, the foundation is laid (copper pipes and all), and the forum posts come complete with finished slab pics, though there is no house to speak of yet.

Bench Power Supply Adapter
Every electronics workbench could benefit from having a bench power supply. Converting a PC power supply works, but often, it involves splicing wires and limits the supply to only bench use, and building one from scratch is definitely an undertaking. To counter this, [silic0re] and his father came up with a detachable adapter that simply plugs into the existing connectors. The adapter provides posts for four different voltages and can be built in no time. It’s nice to see a solution that will let you use any power supply laying around without having to worry about the dangers of opening it or cutting it up.

A Linux Server That Tweets Power Changes
Twitter has been used for lots of experiments, both useful and just for fun. [FIRESTORM_v1] sent in his project that falls under the useful category. When he wanted a way to monitor his server’s power statistics, Twitter was a logical choice. Similar to the Tweet-a-Watt, he wrote a script that posts messages from APCUPSd to a Twitter account that he follows, and gets the updates on his phone. [FIRESTORM_v1] documents all of the scripts he used and the steps to get your server up and tweeting.
OpenPogo, An Alternative To Pogoplug Software
Many of us heard the news of Marvell’s SheevaPlug plug-in PC being released alongside its consumer solution counterparts. One of the prominent products based on the SheevaPlug hardware is the Pogoplug. The Pogoplug is essentially a no-configuration media server that allows you to plug in a hard drive and network cable to make data readily available anywhere you have Internet access. It’s a great idea, but the underlying software is closed source, limiting the demographic of the device to consumers who are happy with an out-of-the-box solution. Enter OpenPogo, a solution for people who want a bit more control over their device. OpenPogo gives users more say over what their Pogoplug does; from running a torrent client to a web server to a Ruby on Rails server. The possibilities for the device are limitless, and OpenPogo makes turning our ideas into reality it just that much easier.
