The face mask has been going through different iterations lately. I’ve repositioned the camera on the back, added new IR LEDs and diffusers and am now using a lithium-polymer battery instead of a DC converter for all the power. This contrast of the image is helped by the IR LEDs, which makes the viewing angle a bit better as well. I’ve also got my Xbee circuit set up on a perf board as explained in the video and as seen in the pictures below.
Last but certainly not least is the Max patch that I’ve been working on (screen shot / .sit). Compare this new patch with what I was doing in the old version. Many thanks to Luke DuBois for the help with efficiency of parsing in Max and to Rob Faludi for help with general Xbee packet information and for letting me borow his dongle.
Next up is getting more screen for the eyes, then duplicating everything and patching them together wirelessly. Three weeks to go!
Hi,
We wanted to know more about your XBee and accelerometer project. We were trying to do exactly the same thing for a different application. We are using the ADXL3xx accelerometer with the XBee Pro, and what we basically want to do is get the accelerometer data wirelessly across through the XBees. So how did you connect them together and pass the data through.
Thanks,
Mike
Hey Andrew,
Basically what we were trying to do was put an accelerometer in an object (like a frisbee) and get it to transmit the data when it moves through the XBee back to a base station w/ another XBee.
So basically what we need to do is connect the XBee with the accelerometer and get the data from the XBee transmitted back to the base. We were first thinking of connecting them through an arduino board but ran across your project.
Did you directly just plug in the outputs X, Y, Z of the accelerometer into the XBee inputs AD0, AD1, AD2?
Also after that how did you get them to interface so that the data got sent through the XBee to the base? Did you use transport mode or API mode? We were also having some trouble configuring the packets sent back and forth between 2 XBees, is there something you need to keep in mind when doing this? Or was there some software you used?
Also do you have any images/schematics/tutorial that we could probably look at to get more help on this?
When you talk about the A/D conversion did you do this on the other end after receiving the data at the base XBee?
Don’t worry about sounding condescending
, we are pretty much novices with XBees, etc. Haven’t played around with this stuff much. All the input we can get will be great.
Thanks,
Mike
