    Something similar to the PDC10

    Mikep, could you give more description on your TNC altimeter? Sounds interesting.

    Giorgio - I've been in touch with the AP4 guy and he is indeed tough to stay in touch with. I don't think he is in production. An occassional eBay auction might be the best way to get one. And then, how well does it work? Any reports from anybody?

    Will this new Palmetto autopilot be in the $100 ballpark also?

    Just the other day I wanted to keep my plane high and level for as long as I could. It was a small model and difficult to see at altitude. I could not tell quickly enough whether it was nose high or low. Wasted altitude and battery juice. Just then I thought to myself...I'm sure glad someone is working on an attitude indicator.
  5. I don't mean to be discouraging, in fact , I hope you do succeed at this. I am not an expert in camcorder technology, but all the camcorders I've seen have a main board, separate from the CCD/zoom lens assembly, that actually does the signal processing/formatting. In other words, the video "head" is just the CCD chip and some drivers. The composite video signal that we know and love is generated on a different circuit board. That board is often the size of the side of the camcorder (large) and populated by a host of other circuits for the VCR part of the camcorder. So, I think it is doable, but you'll have a lot of baggage with it.

    Etrex tear down, whodunit?

    Ok, then that sounds good and doable. I know there are smaller GPS engines out there, but this might still be the smallest with a built-in waypoints/routes structure. Thanks.

    Etrex tear down, whodunit?

    So weight is approx. 1.9 ounces. Now, about those switches...looks like they might stay with the board, but can't quite tell. Thanks Scoob.
  8. I remember someone in this group taking apart an etrex GPS unit to save weight. I found instructions on how to do it. Anyone remember any details? What is the eventual weight? Are the operation buttons attached to the case or to the board? After setting up and prior to a flight, might it be possible to also remove the LCD while still maintaining in-flight operation?

    Nice work. This project is really coming along nicely. I'm so impressed that you didn't stop with the first set of edge sprites and persisted to achieve nonjittery ones. Please count me in if you need a beta testor for your first run.

    I did notice that the new version of the co-pilot does not use the sensors for continuous autocalibration. If I recall correctly, the extra 2 sensors are intended for inverted roll recovery. (Now for some speculation) However, if you do have the two sensors and take them to be always "basically up and down", then you can sample and average them to determine the valid temperature differential for a given moment between sky and earth. If you are in a 90 degree bank forever, this could cause a problem. However, this problem could probably be mitigated with proper averaging and maybe with disabling autocal when autopilot gives strong banking commands. Actually, one can probably threshold the temp differential and use that as an autocal off command.

    9600 FSK modem - success!

    Wow, Cyberflyer, that is an accomplishment. Congrats. I wonder how well the audio channel of other video Tx will cope with 9600 baud? What does your breadboard look like?

    Yes, SMT is way to go. Plus it makes the electronics in our aircraft look so much cooler :-)

    Sorry for continuuing, but a question I have is how to handle an over range situation? Imagine the horizon falling below the field of view of the camera, would the glyphs simply be pinned down? I guess I'm thinking that if they had exponential travel, they could still be yielding some info when over ranging? But, perhaps my head is in gimbal lock and I'm way off base here?

    I too would be enthusiastic with the edge glyph attitude display. However, it might be more intuitive, if not traditional, if the two glyphs were on opposite sides of the screen. In that way a line (imaginary or actual) could represent pitch & roll by whether it was high/low and flat/diagonal. And just because it is easy at this stage to wish for the moon, how about remotely controllable on/off glyphs to facilitate recording clear video?
