starfish_pbx_public

Starfish PBX takes the very popular Asterisk telephony platform and adds an open source, fully functional web management interface. Asterisk allows you to be your own private branch exchange; think of it as your own telephone company. You can setup extensions in your home or office, configure an intercom system, implement a hold system with music, manage voice mail, and integrate Voice over Internet Protocol. Starfish PBX, available in alpha release today, aims to make Asterisk available to a wider user base by simplifying the interface used to setup and maintain the system.

I-Swarm Robot Update

I-Swarm_Micro_Robot_On_Thumb

Back in October we reported on the I-Swarm robotics project. [Travis] sent us some more information. These tiny robots are programmed optically and are able to respond to programming commands via an infrared signal. Locomotion is facilitated with piezoelectric actuators and the power to the units provided through a solar cell. It is not clear that this project is still ongoing as the I-Swarm web page lists a project termination date of 6/31/2008. That being said, the video embedded after the break was posted two days ago showing swarm movement and detailing the programming, testing, and hardware specifics.

Internet Enabled Furby

[edwindertien] sent us his project to connect a Furby to the internet. The original Furby controller was replaced with an Arduino which in turn was given ethernet connectivity via a LANTRONIX XPort serial ethernet module. This assigns the Furby an IP address which can then be accessed through a script or via a web interface. Now we want to see someone combine this idea with the arduino that sings “Daisy Bell” to make the ultimate in creepy new email notifiers.

[Peter Kirn] over at Create Digital Music takes an in depth look at the process of adding your own music to Rock Band 2. This involves using REAPER audio production software, uploading your work via the XNA Creators’ Club, and then playing the fresh track on an Xbox 360. Both REAPER and the XNA Club cost money, and the total price comes out somewhere between $100-$160. The process is now in closed beta but a wider beta is expected in September followed by a full release in October.

Next week, August 31 through September 4, is Ubuntu Developer Week. If you’ve always wanted to help out with an open source project but didn’t know how to get into it, this is your chance. The week consists of 25 one-hour sessions held interactively through IRC and led by some of the best of the Ubuntu development team. Participate in as many or as few sessions as you want. Check out the Ubuntu Developer Week page or their fancy brochure (PDF) for more information.

Want to see what it’s all about before committing to a live session? You can view the IRC logs from the January sessions. In addition to ‘Getting Started’, you may find the ‘Packaging 101’ and ‘Launchpad Bug Tracking’ session notes interesting.

Center Brake Light LED Retrofit

[Matt] wanted to increase the intensity of the center brake light on his car. The factory installed light uses a 20w incandescent bulb and although aftermarket LED replacements are available, he decided to take the retrofit on himself. Using the Fresnel lens from the light assembly as protoboard, he mounted a row of 10mm LEDs along with their current limiting resistors. He then broke the glass from the original bulb, removed the filament, and soldered directly to the two electrodes. This way the bulb socket can still be used to connect to the car’s electrical system.

Beef Up Your UPS

[Surferdude] was unhappy with the decreasing life of his aging uninterruptible power supply. He decided to beef it up using marine batteries. He extended the battery connections outside of the UPS case using #10 wire and swapped the two 12 volt gel cells with the heavy duty lead-acid batteries. Doing so upgraded the device from 20 amp-hours to 84 amp-hours at a cost of about $160. If you’re thinking about taking this on yourself, pay attention to the countinuous output rating of your UPS to prevent a fire risk.
