Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Looks good,

What is it? (to me it looks like you will send it up in a rocket or something.)

HAB (High Altitude Ballooning). Lots of interesting info if you Google "hab balloon tracker". Looks like Jed's off to near space again!

paceman is correct I use it for High Altitude Ballooning but it could track rockets/model aircraft ect

It uses a 10mw licence free transmitter on 434.xxx Mhz to transmit DATA (there is another post on here that details one of the prototype test flights)

The power supply is a single AA/AAA Lithium with a very efficient (94%) 3.3v step up regulator, I am testing one now with an AAA its on 60 Hours so far

To get the endurance the RTC puts the CPU to sleep in between transmits and disable every thing I don,t need on the GPS

In sleep mode it draws just less than 6ma

Doesn't look like there is one on this version Jim but there was one on the last version here: MM rocket.

Well I guess Phil (White Wizzard) won't complain - nothing like a consumable processor for business!

And 0.83v - a true last gasp. How did you manage to get a trackable signal out at that level. I guess it's probably been downed by a Russian SAM by now!
