 The Robot Brain I'm planning to build a robot this year, and a robot needs a brain. I decided to use a Linksys wireless access point running OpenWRT with some hardware mods as the onboard computer that would coordinate communications with a much more powerful stationary system and would interface with various onboard microcontrollers. After some digging around the net, I decided on the Linksys WRTSL54GS. My main wireless access points are WRT54GL's which running OpenWRT ... Title: Building Robot Drive Trains Any 10-year old Lego Mindstorms engineer can tell you it is not always easy to get your bot to go where you want it. In Building Robot Drive Trains, authors Dennis Clark and Michael Owings provide an introduction to building motor controllers and simple drive train systems to help you get that bot where you need it. Here's how the chapters play out: ... The Blender3D project is one of the most successful open-source projects there is. If you aren't familiar with it, I recommend taking a look. Blender3D is a cross-platform tool for 3D artists and animators and even useful to game developers. But it isn't a CAD system; or is it? Robert Burke has written an excellent web site and e-book on using Blender for engineering. While I don't see SolidWorks giving up market share anytime soon, I think Blender ... MAC Spoofing Ethernet cards have a special number, called a MAC address, that is used whenever it talks on the network. This MAC address is how the interface identifies packets intended for itself. Each packet transmitted on the network has a source MAC address and a destination MAC address. MAC, for inquiring minds, stands for 'Media Access Control'. Whenever the network interface receives a packet, it checks the destination MAC address specified in the packet against its own address to ...  Title: Build Your Own All-Terrain Robot I'm planning to build a robot this year - not a cute, cuddly little thing scared to death of the big outdoors, but a serious workaholic. Most books I've picked up about hobby robotics are about little tiny bots that couldn't outrun a flea. This book is different. The type of robots covered in this book weigh hundreds of pounds. ... Kids love robots. Several months ago, for family movie night, we watched Short Circuit. I have four kids and they enjoyed it. Especially my youngest – at the time just about to turn three. She couldn't stop talking about the robot and what it did, everywhere she went and to everyone she talked to. I asked her what she wanted for her birthday - “Robot!” came quickly. Just to make sure I hadn't lost count, ... More about the new server. I have been programming since I was a teenager. I started on a Commodore 128. I've written code in lots of languages. Until a couple years ago, I would have told you my favorite programming language was C. My next favorite was assembly. But then I got a little tired of programming a few years back - about the time everyone else was moving to either Java or .NET. I never really cared for ... Here goes. When a friend of mine suggested I try blogging a couple years ago, I initially thought perhaps the stress of a small business startup was getting to him; it gets to a lot of people. Now here I am. The idea of publishing information in small doses, as opposed to all the work that goes into a book project, is appealing. I have a lot of interests and enjoy experimenting with different things. In my ...  Web Hacker Boot Campby Gerald Quakenbush ISBN: 097684071X, 236 pages, $39.95 Some of the most serious security flaws on the Internet today are application-layer flaws in custom web applications. Such vulnerabilities undermine all other system hardening efforts. While techniques to exploit application-layer flaws are common among hackers, most security professionals have little experience with them. This book is a self-paced training guide that will help security professionals and web developers understand how many application-layer ... StealthVNC is a slightly modified version of the popular VNC tool. It is far from a bona-fide root kit, and it really does need some work, but it is a handy tool for pentesters. But beware I used an older version of the source and at least one of the mods introduces some vulnerabilities; so use it with caution. Here are the essential changes made:
