What is Asterisk? SYSTM video!
New SYSTM! – “What is Asterisk? Asterisk is an insanely powerful, yet easy to use, open source voip telephony toolkit (server software) that runs on virtually any platform. It allows anyone to manage VoIP services in their own home in more powerful ways than the most expensive PBX (public branch exchange). For example, it can serve as a gateway from a VoIP service to your copper phone lines, forward calls to your mobile device from wherever you are, allow you to create VoIP connections to anyone on the Internet, manage voicemail, prompts … a virtually limitless capability depending on how far you want to take it.” [via] Link.
Scott writes “Here’s an inside look at the legendary Survival Research Labs shop where they create the robots and machines for their amazing shows. It’s been at it’s current San Francisco location since 1982, but will soon have to move.” 
Handy how to from Bob Bilson on Instructables “Need to ship out something, but you don’t have a shipping box? Check out the copy machine. Grab an empty copy paper box and follow these instructions.” 
Nice outdoor webcam installation – “…the final webcam installation including painting to comply with our homeowners’ association. You may need a stepladder and a piece of cardboard to “frame” (as a movie director might) your intended view from a workable location in space. If you’re lucky, you just attach your cam housing to an existing surface. Get a sense of the angle of coverage afforded by your camera before you do this. High school geometry and its study of triangles may be finally useful to you here.” [
Mac writes “A while back, I happened upon the application note “Interface to Optical Mouse Sensor” on the Kronos Robotics website. It discusses the use of a sensor from an optical mouse for use in position sensing coprocessor on a robot. The application note did not go beyond the proof-of-concept stage. That is, could the sensor be directly interfaced and controlled? Since I didn’t have easy access to the GE mouse described in the application note, I wanted to see if there were other optical mice available that had an Agilent optical mouse sensor, which I could use in its place. I also wanted to go beyond the proof-of-concept stage and acutally use an optical mouse sensor in a robotics application. Before developing that application, though, I first needed to gain familarity with interfacing to the optical mouse sensor in a Forth environment. This webpage describes the hack I did to a BTC optical mouse to enable direct control of the Agilent (now Avago, see below) ADNS-2610 Optical Mouse Sensor and the Forth code written to control it.” [
This is a really clever idea, burn images along with the data on a CDR… Instructable maker Argon writes – “By carefully choosing the right 1s and 0s to burn to a CD, it is possible to burn visible images on normal CD-Rs. These images rely on the fact that the 1s and 0s created by pits in the CDs surface reflect light differently.”
