wireless.gumph.org has a how to on making a small WiFi antenna – “A small antenna to boost the signal of a laptop wireless card, that can be stuck to the back of the laptop screen. The design is the same as for the larger homemade antenna, but uses thin RG58 cable and is only 2 sectors long. The size was chosen so it could be housed inside the tube of an old pen, to provide rigidity and protection to the antenna.” Thanks Star! Link.
Here’s a homemade remote control pan and tilt system mounted on a competition class RC car. All controlled wirelessly, with the video piped into a head mounted display. We’ve all seen those minicameras mounted on RC cars but never like this. Awesome mod! Link.
Dissident75 shows how to set up a cheap xm radio in your house without buying the “home kit”. All done with cheaper/free parts. “This weekend I was bored and needed to do something. I had purchased a Roady2 XM Reciever for a exgirlfriend but broke up with her before giving it to her. Seemed like a shame to let it go to waste, and I had been curious about satellite radio for a while. Examining the package, it was a standard car install kit. Including the receiver, the antenna, 2 types of mounts (vent and pedestal), a tape adapter, dc power supply (cig lighter), and a few colored faceplate accents. Standard fare really. Useful for a car install but useless for a house install.” Link. In MAKE volume 01 we show how to make your own battery pack too (for XM radios).
Use the Nintendo DS a little hotspot finder, Natrium42 iin 3DGPU forums writes – “DS2Key uses DSWifi library by Stephen Stair. The “Wardriving” functionality comes straight from Stephen’s example code and a test NDS binary with this functionality can be found at the above link. Stephen recently won the DS Wi-fi bounty.” [via] Link.
“For quite some time it has been possible to access the Internet using mobile phones, although the role of the phone has strictly been that of a client. Considering that the modern phones have processing power and memory on par with and even exceeding that of webservers when the web was young, there really is no reason anymore why webservers could not reside on mobile phones and why people could not create and maintain their own personal mobile websites.” [via] Thanks Brian!

Restoration of a HUGE AM/CW transmitter from the 50’s – “This article describes my restoration effort of a Globe King 500. I estimate that I expended about 100 hours on this project. It took a lot of tenacity, it was at times tedious and frustrating, but overall it was a very rewarding as well as an educational endeavor. I have included many pictures of the project at different stages. I hope you find it interesting but more importantly, I hope you can learn from my mistakes and newly gained experience.” Link.
Nathan True’s excellent mobile hotspot – “Wouldn’t it be great if I could just plug my phone in… and have it automatically connect to the phone and serve its sweet, sweet Internet over a Wi-fi connection? Better still, have it transparently proxy all connections so that nearly all Internet programs will function properly? Maybe even prioritize certain types of traffic, or encrypt everything so my wireless carrier can’t spy on what Slashdot stories I like to read? All of those things would be just great. And all of those things are exactly those things which I set out to do (and/or enable you to do!) in this project. ” [via] Link.
