I designed one last century. We built maybe 50 or 60 of them over the years. Very simple, very low cost and, by the time the firmware hit V7 point something, pretty schmick too. Had remote controlled arming and programming. Mach proof (velocity based) apogee detection...


I still have some which I still fly. I think I have 1 from last century, but that one's more of a museum piece now.

Sounds ideal - put me down for one.
These would also be useful for altitude competitions.

Hi all.
Anybody have any tips on soldering SMD( my teacher needs to reattach the sensor to his altimeter).

Dave has a good tutorial on how to solder SMDs with some good tips:

Hi
So PK have you made any progress on the dual deploy altimeter. I was thinking of getting an altimeter to put into my 2.1 inch. And then proceed to use in my future endeavors with dual deployment. Still if it was sub $30, I would seriously consider it.

Mathew

Sorry for asking again PK but any progress. It's just I need to know to design my avbay around it. And how to you think to power it. Small lipo?

Nup, the altimeter is still behind the Beep-o-matic and launch controller (and maybe a rocket kit). At my present rate of progress I should have it done in time for your retirement.
I appreciate that, at 14, life feels like it's moving very slowly and your challenge is to fill the day; but as you get older life accellerates and becomes a headlong rush to the grave... We will get there though...

Mmm. I mean the rocket probably won't every fly at the rate I'm going :D. Mainly if I just know the size I can make a little block to represent it to make the av bay around it.

. Interesting. Happy to help with the design.

Single cell LiPo, same as the uMad.

This one's a little bit bigger, but I have a few extra boards made.

Part cost is a bit higher than your $30 though.
