Alright, I guess I gotta get a set of xbee's (Questions)

Really this is just a couple questions. First off, is there any reason not to buy the cheap ones? They start at about 25 bucks and go up to quite a bit. I don't need super-duper solid data, and I will need very little range, can I use the cheap ones? --Also, and I can't believe that I can't find this on the website, but the price I am looking at is for one unit, correct --not a pair? Gimme any thoughts you have.

This is what I am looking at.

Picaxes Latches, Clocked Serial and I need an Enabler

I am working with a ShiftBrite RGB led and I have it working nicely with an Arduino. The curse of course, is the fact that Arduinos have libraries and a lot of the "work" has been done for you. Now I want to get this guy working with a Picaxe and I am looking for a crash course on clocked serial, latching, enableing (sic) etc.

Learn me in my head with stuff you know good.

This is how to plug in a LED to a Picaxe 28

Tell me again why I had to look this up for you?


Little Concerned with the Show Tomorrow. 9.3.10

Hey guys,

I just shot an skype message to rik saying the same but I am a little worried about the show. Actually, I am a little worried about my house. Hurricane Earl is on his way up here and seems to not be loosing strength like we thought it would. What was first a prediction of 40MPH winds has been upgraded to 75+ MPH winds. To cut to the chase, this is sorta serious. Now, I'm an ol' Kansas boy so this is just a wet tornado to me, but folks around here remember Bob and assure me this is nothing to underestimate.

Walter Docking off of Compass and IR Beacon

Done. Done. Here is what I have learned. Compasses are great, just great --I am using a HMC6352 (because of a kind LMR brotha) and it simply puts out good clean data with very little flutter. HOWEVER... I have quickly discovered that these compasses do not like magnets --or to the point, they like them way too much! I had to remove my big-ass speakers from the room as the the big magnets on the woofers were throwing things off. With them removed and a quick calibration routine I am getting solid numbers each time.

38khz 3-Pin IR Receiver and Wavelength of the IR LED

I just can't seem to find this through google except for actually looking up a diagram of the "full spectrum" so I need a confrimation here. The IR led's that glow a dim red are the one's in the 850nm range, correct? The ones that are "invisable" are the 940nm ones, is this also correct? Also, the 850 is a "stronger" light source? And finally, I can't seem to find a mention in the specifications of the receiver if it will respond to either wavelength.
