For a second there I thought it said, "Tips on Waterboarding"....I was like whaaaaa?

I was actually considering building one the minute I came across the website on Engadget (or was it RC Groups?). Anyway, I'm going to figure out what the total cost will be first, then I'll decide. It's a great platform for AP that's for sure.

The way polarizing filters work, it can be a bit of a challenge to keep the filter at the best orientation with aerial photography. Polarizing filters work best when the sun is at a 90 degree angle to the object you are attempting to photograph. In other words, if a giant photographer stood in the Atlantic Ocean pointing his camera at the United States to the west, he would get the best results around noon when the sun is at a 90 degree angle to his position. If you were to use a filter on a camera that is pointing downwards towards the ground, you would have to fly parallel to the sun, (not t

I don't mean to clog this thread with a basic question, but since this is a diversity receiver, and as such provides a solution to the multipath problem, will it effectively eliminate ghosting? Especially in the 430MHz UHF band? Sample attached:

I'd like to build a diversity receiver to be used with 900MHz and 400 MHz. Now, I know some of you have built 2 way and 4 way diversity receivers using PIC controllers. However, I was interested in building one that I could find tutorials of online or perhaps step by step instructions so as to save the time involved in learning a new programming language and going beyond the scope of what a simple device would or should require. I have come across this http://www.cyber-flyer.com/video/div_schem.jpg schematic and I have to ask, does anyone have a CAD file with a parts list that I could send

The Xenarc product line seems to be popular among members of the mp3car forums.

EB-85A (5Hz), of course.

I would be interested as well.
