Wifi Robot August 2008 Wifi Robot: A remote control car that can be driven over the internet or with a laptop wirelessly from up to 500m away. It has a live-feed network camera so that it can be driven without line of sight and a horn so that you can honk at people. A while ago I discovered the Linksys WRT54GL router. The goal of this article is to give a high-level overview of the project and provide some implementation details of the software and electronics. Car Adding a network camera, router, heavier batteries, extra circuits, and a whole bunch of wires adds a lot of extra weight that the car wasn't designed for. I have taken apart about 20 RC cars. Router I've modified my WRT54GL to have 2 serial ports and a 1GB SD Card (acts like a 1GB hard drive). Later in the article links and information are given that can help you wire up your serial ports and get them working. Microcontroller Selection I evaluated three different microcontrollers for this project. Steering Circuit Batteries Camera

Or serving up sensor data world-wide? This shield allows you to add and use an XPort or XPort direct(+) Ethernet module (they cost only US$30-$50) using any 4 pins or a WIZnet Ethernet module (US $16-$25). Specifications Shield allows use of XPort, XPort Direct, XPort Direct+ (for a rundown of the differences between these modules, click here) or WIZnet 811MJ Completely compatible with the official Arduino Ethernet library and examples when used with a WIZnet module. 3.3V 250mA power supply on-board for powering the modules Arduino reset button and 6-pin ISP header brought up top for fast & easy development Check out the XPort examples here and the Arduino Ethernet/WIZnet examples to see how easy it is! Please note, this shield is not designed for WiPort or Matchport modules (wireless 802.11) or other ethernet modules such as Rabbit, etc.

Home-Made DIY CNC Machine using Step Motors, Dremel, and EMC2 | Lirtex - Technology on the Edge of Time Tags: CNC, DIY, Machine, Motor Control, Robot, Robotics, Stepper Motor What is a CNC? The abbreviation CNC stands for computer numerical control, and refers specifically to a computer “controller” that reads G-code instructions and drives a machine tool, a powered mechanical device typically used to fabricate components by the selective removal of material. In simple words, a CNC is a machine which is controlled by a computer, and used to fabricate 3D objects. This page will describe the process of building a CNC machine, from the design stage, the required materials and the process itself. Still confused? After seeing the movie, you must have understood how useful that kind of machine is for printing electronic circuit boards or manufacturing robot parts. But as I say – “If there’s a will there’s a way”.

Roomba, Economics and Long-Exposure Photography | signaltheorist Hi Reddit! – DigitalOSH Earlier this weekend I picked up a Roomba , as my old vacuum cleaner bit the dust(ha!) after an altercation with a shoelace. Pros: -Consumers end up designing functional modifications, which can be used in later versions of the device-Hacking voids your warranty, thereby reducing warranty claims-Revenue from sales of hacking tools/interfaces-Active community promotes the product Cons: -Brand diluted by other items under Roomba name-Brand may get an image of being complicated I’m sure I’m missing some obvious ones here, please comment. Now here’s something interesting, I set up a photo camera in my room, turned out all the lights and took a long-exposure shot of my roomba doing it’s thing for about 30 minutes. I’m such a yuppie.

Digital Audio Cables One of the significant developments with the widespread adoption of the personal computer for home, business, and school use is the digitalization of media and the subsequent mass adaptation by consumers and industry. While digital media is not a new concept, it has only recently made its way into the “normal” household and is commonly supported by digital audio cables. As a result, higher quality audio playback is now supported while watching movies or listening to music that can approach (or at times exceed) the experience found in a high-end movie theater. While architecting the perfect home or work audio setup, some consumers neglect to identify the proper digital audio cable (vice analog) to use in their respective entertainment system. What Are the Types of Digital Audio Cables? The two most common types of digital audio cables are coaxial and optical digital audio cables (also referred to as S/PDIF). How Do Coaxial Digital Audio Cables Work? HDMI Cables 3 – Budget. Speaker Quality
