In Topic: Pachube client for NetduinoPlus

14 February 2011 - 05:38 PM

What would prevent you from monitoring your house using a webserver that sits in front of your sensors? What does it give you to push sensors data to Pachube? By nature some sensors information are to be shared (examples: meteo, road traffic), but light condition or room temperature are not to be shared isn't it? I know that my project involves temperature precisely, but this is just a proof of concept, not what I'll be doing. I'll end up with just the webserver running in my NetduinoPlus (in fact the target will run on a Mini).

I though I could use Pachube for long term data logging.

Are there any other similar services like Pachube? It's a fantastic idea, but it's a bit to expensive. If I want to monitor my whole house and keep a infinite history, $99 is to much for me.

Brandon mentioned in a other Post that you will move to gitHub, so?
I want to fork ^^ so it's easy to merge our codes =)

Edit: forked it :)

I have the same, but my ESC's don't care about the short absence of the PWM. As soon as the PWM is alive the ESC's are initialising. But my FEZ Domino does not take a couple of seconds to boot.. Just about one second.

But if I take such a 9dof stick, I must make all the calculations on the .netmf device.
The Razor 9dof would do all this calculations:

Direction Cosine Matrix (DCM) based Attitude Heading Reference System (AHRS) with gyro drift correction based on accelerometer (gravity) vector and magnetometer (compass) vector.


I have binary messages over serial: [type:length in byte]

[DIYd:4][ID:1][roll:2[pitch:2][yaw:2][checksum:2] => 13byte

But how to request data on demand? just send a byte to the Razor and respond?
