Propeller based flight controller update

Hi All,
Thought i'd drop in a quick update ony my project.
This is a inertial & barometric rocket altimeter with logging, 3x pyro channels, USB interface and expansion port.
Overall size 1"x4".
I took these pic's a little while ago but have only jusy gotten around to posting them.
Still have to start soldering the board together, I hope to do this is the next month or so.
Ive started writing code for the prop but haven't been able to test yet for obvious reasons!
Thanks for looking [noparse]:D[/noparse]

It would be cool to see a graph of altitude data vs time from an actual flight, when you get to that point.

I certainly will post graphs [noparse]:)[/noparse] At first I will be using a simple 10sample average to smooth the data, then once thats working I will try my hand at a kalman filter [noparse]:)[/noparse]

What happens when it rotates on the vertical axis?

For now the data will be a bit skewed. Inertial measurements will be used for velocity and acceleration approximation for this version of the board, and the barometric sensor for altitude approximation.
I plan to add 3 axis accelerometer to the next version.
This one was done in Eagle and I have BatchPCB make it. For the next version I am using Altium Designer (a bit of a learning curve!)

That is a neat looking PCB well done.
Looks very neat ..
Checked out the webpage as well.. cool stuff
Just don't aim any of those V2 rockets our way...across the strait..
cheers

Am I allowed to say that?
