The R.Pi is excellent module for many applications. Unfortunately it is not easy to stack USB modules connected to it. When USB module, e.g. RTL-SDR is attached to the R.Pi, the whole package become very long requiring larger box. One solution is to use USB extension cable, but it again require additional space. Here is another, more compact solution:
- remove the USB connector from your module
- place SIL header at the pins for USB connector
- connect the USB module back “folded around the corner”

I took old cover from plastic sewer pipe (it was never used ha ha). Then I drilled four holes for M3 screws and one bigger hole for camera module lens. The housing was prepared from one litre PET bottle. I cut the bottle to proper size and inserted raspberry Pi with the camera inside the bottle. Next the LAN cable with passive 5V “PoE” was inserted.
Finally, I heated the bottle with hot air gun at the camera side to shrink a little bit and tightly close the gap between the plastic camera “holder” and the bottle .
Photos below will tell more than thousand words:

I recently set up a APRS gateway. Check instructions in older posts. In the script pymultimonaprs you can set weather when set in a json-file. eg: “weather”: “/path/to/weather.json”. I live next to the automated weather station for our city. Instead of building own WX I decided to use the data from this nearby station. The data is provided in XML from our national agency ARSO. The data is available for some major cities in Europe, too.
Main idea was to prepare PHP script to parse the XML data and prepare text file, which is acceptable for pymultimonaprs. Next step is to wget this text from some server and copy it to the raspberry pi with cron job.
This page will give you an example how to:
- parse XML file with weather data using PHP script
- output the text for pymultimonaprs weather file
- prepare cron job with raspberry pi

This is part two (here is part one) of the tutorial how to use Raspberry-Pi in APRS gateway.
In part one I explain how to install OS for Raspberry Pi and get RTL dongle up and running, which enables radio reception and listening received signal with FM demodulator on audio jack (simple FM receiver). For next steps you will need HAM licence with own call sign. Mine is S54MTB.

Introduction
I have couple of raspberry pi’s laying around doing nothing useful. I decided it’s time to use it better than dust collectors. This tutorial is placed here for reference for any OM who would like to setup APRS Rx only node based on R.pi. Here’s what you’ll need (hardware):
… and software:
