I have had this board in my hands for over a month and I have to say that this review may be a bit complicated. I feel that I not only need to review this board … Read more

X-bee as a ADC "adapter" or "converter"

Fogive me, I read and re-read the data sheets but can't seem to find this. And I know this is a long shot. The ADC channes on an X-bee --they are just data-in, data-out right? I put an analog signal in one end and I get a PWM signal (equal to the input value) from the other end, correct? Is there any way to use the ADC inputs on an x-bee and get those values out via it's TX data pin? I am trying to put together a work-around for the lack of ADC's on the propeller and I thought, hey --the xbee's have ADC inputs, can I use them? I mean, I already have the x-bee on-board, why not use it?

Kinect Navigation... Done. (Man, MIT guys work fast)

And this is what I call navigation.

Hey! Micro 180 deg Pan and Tilt $20

This just crossed my path and it is very cool --A micro pan and tilt with some extra gearing to get 180 degrees outta the "pan". 20 bucks (20 Squids), too. I want one.... No, I wanna build one!

Servos going to first position in a violent way.

This is an open question on the problem of the violent twitch/swing servos have when they are first turned on and when they get their first position command. The obvious answer is to always finish a "session" by centering all your servos and then turning off, but this assumes that nothing is going to get bumped or creep out of "centered" while waiting for the next time it will be turned on. One could also center all the servos by hand (with the servo unpowered) but I have never cared for moving servos by hand if I can avoid it.

Serial Port now available on iPhone

I gotta be honest, I didn't have a chance to actually read this article before I posted, but it is an iPhone, with a big-ass adapter and a 9-pin serial plug coming out... That's good enough for me!

http://www.computerworld.com.au/slideshow/365979/great_iphone_serial_port_hack/?fp=4&fpid=5

Again, to be honest --I don't know if this iPhone advance or serial-whatever will help any of us buy hey --I saw it on Boing Boing and you can't go wrong there!

Propeller Journey 008 maybe?

Encoders and The Man with Two Brains. (It was Dr. Huuhururrr by the way and I swear to God, I didn't have to look up the spelling).

So I am running 2 cogs now. One is running my motor and the PWM signal going to it. The other cog is keeping an eye on the encoder. I think the video is self-explainitory.
