Survival Research Labs at Fringe Exhibitions, LA…
New SLR! Saturday, January 21, from 6 – 8 PM in LA. “This exhibition will feature the newest addition to the SRL machine family- the Sneaky Soldiers- near life sized, remote controlled army of revolutionaries. Also included in the exhibition will be large-scale documentary images, and the premier of the video from SRL’s recent show in Downtown Los Angeles. This video features the first invasion of the Sneaky Soldiers. The SRL commentary on the art of war debued a Sneaky Soldier emerging from an 18-foot tall wooden Trojan horse to face danger from large-scale destructive robots enduring the pain of flame and damage through a hail of sparks and projectiles.” [via] Link.
We spent some time with the new Intel-based Macbook. Wow–it’s super fast. As we take photos, we’re automatically uploading them to Flickr via WiFi-Kodak wireless camera and the roaming EVDO Wifi network we’re broadcasting — so here they are, some of the first photos with hot system info action, too! 
Derek writes “The gumbrix came about because so many of my robot projects required the kind of rapid prototyping that Lego really excels at, yet required more in the way of control electronics than Lego was capable of. With a maximum of 3 motors and 3 sensors, the Mindstorms kit was not really capable of the more complicated control strategies that I was interested in.” [
Chad writes “For a while I have wanted to control things with a serial port. It was pretty easy to control a relay with a serial port. With a standard serial port you can control 2 relays. (with a parallel port you can control 8 relays, but I don’t have a parallel port on my system). A standard PC serial port has 9 pins. Pin 4 – DTR (data terminal ready) and Pin 7 – RTS (request to send) can be used to control a relay. These two ports don’t actually send data. They are used to signal the other device to tell it when to send data.” Here’s the HOW TO – 
“BFO (beat frequency oscillator) metal detectors use two oscillators, each of which produces a radio frequency. One of these oscillators uses a coil of wire that we call the search loop. The second oscillator uses a much smaller coil of wire, and is usually inside the control box and is called the reference oscillator. By adjusting the oscillators so their frequencies are very nearly the same, the difference between them is made audible as a beat note, this beat note changes slightly when the search loop is moved over or near to a piece of metal.” 
“A small wireless battery powered device – Turn it on near a friendly wireless network that contains iTunes shares and plug your headphones in. It picks a random iTunes share, picks a random tune and starts playing. Repeat until bored or the batteries are dead. The size of the system is amazing. The main board is about the size of my little finger. By default it’s running an ssh server, a web server and advertising itself to the network with bonjour.” 
Robotsrule writes “I have made a new video to show some of the capabilities of the new, upcoming version 3 of Robosapien Dance Machine, the free open source program that lets Windows PC users create complex scripts to control their robots, and control their robots using just their voice. This 1 minute 3 MB video demonstrates the support that version 3 of Robosapien Dance Machine will have, for all of WowWee’s robots; including the Robosapien V1, Robosapien V2, Robopet, and Roboraptor robots.” [
