Guys, I just received one of these cameras. I ordered it about mid-day on Friday the 24th. Monday the 27th was a holiday, and the camera arrived here on Tuesday the 28th - that's essentially one...

For those who are interested in duplicating my results, the camera I used is the original Contour HD 1080P. It has a 120 degree lens, unlike the Contour Roam or Roam2 which have 170 degree lenses...

If the camera presented by the OP is as good at video as the 1080p Contour camera, the quality will be much better than those keychain cameras. Size matters (at present). There are no keychain...

Yes, mounting via the RPSMA connector is a viable solution, even moreso if you construct the tracker within the footprint of the XBEE itself.

This is my third protoype, and I think the final PCB...

Here is an idea that I haven't seen discussed yet. If you aren't squeamish about soldering, you can remove all the pins from the XBEE and the two sockets from the XBEE adapter, and then install the...

The APRS protocol using X.25 UI frames was what I meant. This is run over networks routinely, and digimesh is just another network. From what I've read, the aux processor on the XBEE radio sits...

Antenna mass is not a significant issue in my case. I plan to install this into a big rocket. You will probably trade mass for range when using a wire antenna in lieu of the dipole. Have you done any...

Derek, you might consider an alternate layout to save more space - like mounting the GPS on the opposite side of the board from the Digi transceiver.

Here is a prototype I assembled using 2 of the...

I think it is Molex 51005

Perhaps not ideal, but here is one possibility:

300mah, 1.6 X 0.8 X 0.16 (40x20X4) with bare wire ends:

Ebay LiPo

If you mount a right-angle connector to the edge of your board, this would...

LOL. I was searching for a somewhat more definitive explanation for the difference. :tongue:

This sensitivity-difference topic really has nothing to do with building or using Derek's GPS tracker...

The -002 modules my cuz and I have are rev B. I may get brave and try to load XSC firmware on both of mine at some point - just to see what happens to P2P range. I am curious as to why the DM...

I found the note to which you refer:

http://www.digi.com/support/kbase/kbaseresultdetl?id=3325

The radios we are using are not XSC modules (the note applies to S3/XSC or S3B/XSC - not to...

Maybe this has more to do with which USB module you use? I don't have an accurate schematic of mine - which is a Sainsmart unit.
...

This has not been my experience so far. We used 4 modules new out of the box. One was connected to the GPS module. The second was connected to a PC USB port with an app (either Street Atlas or GPS...

The 10kbs version bears the same part numbers except the dash number is -001 (instead of -002).

The differences in the -001 and -002 variants are:

-001 = -110dbm rcvr sensitivity but NO...

We've been doing some testing with Digi XBee-PRO S3B 900HP modules, and there are some details about how these radios operate to which everyone should be made aware. I hope I am not about to embark...

You chose 3.2V output (over 3.3) to improve the DO margin? It looks like you could go as low as 3.0V without any range degredation if the Digi specs are accurate.

I noticed in the "specs" page on their website and in the user guide that Digi makes a version of the XBEE PRO 900HP module with an auxiliary processor that intercepts the UART connections. This is...

Thanks. Derek didn't mention a regulator in his reply to Dick Moran. I've been looking at readily available 3.3V regulator boards - but they all have input requirements that don't suit this...

The lower limit shouldn't be a problem for the radio - it will run at reduced output power down to 2.1V (but the battery should be cutoff at ~3V). On the other hand, Digi's upper limit spec is 3.6V....

He meant the prosign "dih-dih-dih-dah-dih-dah" (with no space). There's no character set that will put a bar over the "SK", is there? I tried using underbar on the line above, but the spacing gets...

Weather was perfect today, had a great time with a good number of flights. The Christmas tree drag race was a crowd pleaser.

When using the rubber duck, do you actually end up using the last position that was transmitted before the rocket reaches the ground? I ask because when I used the BRB GPS beacon in my nosecone at...

My tent was at the end of the flight line nearest the away cells, and the Disco folks setup right in front of me. They called for folks to stand at the fence and pretend to be excited, scream,...

They used my onboard footage twice in the show - once near the very begining and once about halfway through.

It is easily recognizable because I accidentally had the camera lens rotated 90...

Really? Is there any video or web reference for that? Google search of 'discovery channel LDRS 18' yields nothing.

I got re-acquainted with rocketry by happening upon LDRS 19 in Orangeburg. I was...

LOL!!!! I'm sure it was keeping you up at night.

The "PS" in my post was an edit - after I had done exactly what you suggest here. I could see that the battery voltage sagged heavily, and that the main channel voltage was just following this...

Here is the Raven3 FIPa file from my flight today. The rocket is a modified Wildman Jart, with an altimeter in the (fully seperable) nose-cone shoulder (or coupler tube). The strange thing about this...
