Weather Baloon Project

by gggggggg on Tue Nov 27, 2012 12:02 am

I am looking to launch a weather balloon in Australia. I will use a R Pi.

My plan is to use a P Pi with GPS module, and a Telstra USB dongle to send data back. So that Telstra dongle will go in the USB port.

Here is my shopping list. Am I missing anything please:

Cable to Antenna - http://www.adafruit.com/products/851
Battery - https://www.adafruit.com/products/380
Starter Kit + Pi - https://www.adafruit.com/products/1014
Breakout - http://www.adafruit.com/products/746

I think I need a Battery pack of some kind, GPS Antenna and 2 x Temperature sensor (one in the payload and one external). Can anyone recommend a adafruit part for these? And while I am there, are there any other sensors that would be fun just to play with that would be compatible?

What about Gyro module for the Pi, so I can log G Force.

And can any one see any issues?

thanks
Greg

The Adafruit Ultimate GPS module is a good choice. One customer achieved 34046 meters ( 111,757 feet ) with one not long ago. https://www.adafruit.com/index.php?main ... timate+gps
We have a variety of temperature sensors. The BMP085 might be a good one because it reports barometric pressure also. https://www.adafruit.com/index.php?main ... emperature
We do have a nice gyro module: https://www.adafruit.com/products/1032
But an accelerometer would be the sensor you would want for logging G-force: https://www.adafruit.com/products/163

Before you commit to a battery pack, get everything hooked up and measure the current draw. Once you know the current draw, you will be able to select a pack with the appropriate capacity for your expected flight-time (plus some safety factor of course).

THanks,

And all these will work with the Pi and the starter kit?

All the sensors mentioned will work with 3.3v logic on the Pi. The starter pack has a solderless breadboard for prototyping, you will want to solder the circuitry to something more robust like a perma-proto or a Pi-Plate for actual flight.

Thanks for all your help.

Is there any alternative for the Gyro:

I am in Australia.

There are gyro breakout modules from Pololu and SparkFun. I do not have any experience with them.
We do ship to Australia. We also have distributors in New Zealand and Singapore.

I mean, this notice on the Gyro

Please note: This gyro chip is export controlled - you can only purchase it if you are in the USA. At this time, we are not permitting resellers to purchase this sensor.


Do you have anything else that you can export to Australia?

Sorry, I missed that notice. Unfortunately, that is the only gyro that we stock.
