Got out my little radio telescope that I built but never used.
I’m using a raspberry pi 4 now. For testing, using RealVNC is very nice. It let’s you view the desktop remotely. Eventually I’ll probably want automated collection/pointing/recording data for which a Python script would be best. But for now just logging in with RealVNC works well.
To install the rtl-sdr stuff, it is actually really easy. I started building from source, then realized you just need to do $ sudo apt-get install rtl-sdr
pi@raspberrypi-tx:~ $ rtl_test
Found 1 device(s):
Using device 0: Generic RTL2832U OEM
usb_open error -3
Please fix the device permissions, e.g. by installing the udev rules file rtl-sdr.rules
Failed to open rtlsdr device #0.
Likewise to install GQRX you can just just go to add/remove software and search for it.
You can search packages by name with
pi@raspberrypi-tx:~ $ apt-cache search gqrx
gqrx-sdr – Software defined radio receiver
The driver from Adafruit has changed for the accelerometer. I’m still using the old depreciated one.
I installed Cheese, then could hook up a USB webcam to verify the dish pointing.
Would be cool to allow other people access, need to figure out a safe way to do that. VPN?
