Compact Powerful Weatherproof Wifi Antenna
January 31st, 2008
Useful plans to build a weatherproof wi-fi antenna. Great for sticking it to the man (your ISP) and sharing the cost of your connection with a few neighbors. This design supposedly triples the gain compared to a standard antenna.

How to Make Printed circuit boards
January 23rd, 2008
So you’ve designed a nice circuit and laid it out on your trusty breadboard. Time to move on and make a permanent version of it. You can always use stripboard and obtain a sloppy yet functional version of your circuit, or go all out and print your own circuit board. Homemade PCBs produce professional looking results without the overhead of dealing with a third party. An excellent option if you’re just making a few instances of your circuit.
This nice how-to shows you how to do that. Just make sure you dispose of the chemicals properly when you’re done. The sink isn’t an option here.
