Hi Björn,

why do you use the version with breakout-board instead gps without?

Hi Björn,

Hi!

Since the GPS needs a backup battery/supercap and since the solder points o the gps itself are sooo tiny...
Ideally a smaller breakout board would be perfect...

Hi Björn,

you could use this identical little one:


from here:
http://www.lipoly.de/index.php?main_page=product_info&cPath=880_1912_1917&products_id=160844

or Breakoutboard alone:
http://www.lipoly.de/index.php?main_page=product_info&cPath=880_1912_1917&products_id=158547

3V Lithium battery can be soldered with two short wires to the VBackup-pads and glued at the top-layer.

This one is similar to the one from Flytron (http://www.flytron.com/osd-headtrackers ... odule.html), except it doesn't have a backup battery. Clearly the flytron one is better and cheaper for our purposes.

But Björn is refering to a newer one which is lighter due to a lower profile of the patch antenna. Unfortunately, no good breakout board is available yet... Maybe the future gluonpilot gps?

Thanks for the tip about another breaout board Penguin (I have that GlobalTop module also). Like Tom points out this is the PA6H GlobalTop module - http://www.gtop-tech.com/en/product/PA6 ... le_04.html - which only weighs 4 grams. The 3egadgets board is nice, but if Tom could amke up a lighter version it would of course be great for us MAV enthusiasts!

Ok, thickness is a new requirement Now the problem is clear to me... thanks for explanation!

While awaiting the GP2 (and better weather) I have been busy making plans for the new autopilot.

This summer I flew the MS Compospite Mini Swift with GP and camcorder and it had a wingspan of 50 cm and weighed around 150 grams.

I found out that there is a Micro Swift and it has a wingspan of 40 cm. A perfect testbed for the new smaller Gluonpilot... Another step towards 25 cm.

At the same time I ordered the Swift II which has 80 cm wingspan and it may be a hand wing for larger cameras and it is VERY light.

Here aresome pictures...

All that's missing now is a lightweight GPS unit (work in progress) and a lightweight XBee board.

I was planning to etch such boards myself but haven't found time yet... Maybe I should place a bet and have some PCB's made right away!

I know for sure that I would buy a bunch from you...
I got some XBee sockets from Sparkfun that I intend to use and if the SwiftMicro can carry the 7-8g's heavy "3egadegts" GPS board, I will have an 80 g MAV...!
I guess we could be looking at a full featured Atto with GPS and Xbee @ 20 grams or so?

Atto? I thought you sold all your attos?

Yes I think 20 grams should be feasible. I could also try to make an extension board with XBee sockets + GPS. The problem here is the connectors might add a lot of weight so we would need to optimize that.

Those 80gr @ 40cm would already be a great job! I remember my "thesis" MAV of 40cm was 120grams and still flew great (even not too fast, but I think the total wing area was larger).
We use this beast inside, only for attitude calculations!
