Bootstrapping a new OGN Station with Rob's help.
Shopping list:
- $65 Antenna Amazon link (NOTE: Do not use the antenna cable it comes with)
- $80 Raspberry Pi PiShop link
- $20 Power supply PiShop link
- $15 High Endurance uSD card PiShop link
- $10 Case PiShop link
- $20 Pigtail Amazon link
- $60 SDR Amazon link
- $25 Powered USB Cable Amazon link
- $20 Weatherproof housing Amazon link
- $40 Webcam (optional) Amazon link
- If getting the optional webcam, then you should get an additional powered USB cable and weatherproof housing for placing it somewhere.
- Assorted nuts, bolts, tapes, zip ties and caulking for your specific antenna mounting. Plan to seal up the weatherproof housing with silicone/caulk.
If your station will need cell network connectivity instead of ethernet or WiFi, then I recommend the Inseego M2000B unit. This will run from USB power, and work with any Canadian SIM card. For the cheapest SIM card, find a volunteer with a Rogers, Telus or Bell plan that allows sharing their monthly data allotment with a $10 "Tablet" or "IoT" SIM card.
If your station will run from a 12V glider battery instead of from grid power, the recommended 12V to USB transformer is the Palumma 24W/4.8A Dual USB Car Charger. If you want solar instead, then you're on your own to find the best 2.4A USB power supply for the Pi.
Steps for after physical installation:
- Find a Windows or Linux computer for the initial setup steps.
- Download the SD Card Image: ognskel-2024-07-19.img.xz
- Windows: Download and unzip the usbimager program: https://gitlab.com/bztsrc/usbimager
- Place the 32GB MicroSD card in a card reader and use the usbimager program to write the image to the card, or use native Linux tools.
- NOTE: If you proceed further at home for testing, you'll have to start over again at the installation location.
- Edit the ognskel.txt file on the SD card to add your WiFi network name and password, save it.
- Place the SD card in the Pi and boot it up
- Wait a minimum of 20 minutes before proceeding. Have a beverage.
- If it is successful, you'll see the setup diagnostics page appear at https://cloud.sosaglidingclub.com/ognskel/ognskel/ognskel.log.
- If it is unsuccessful, get the ognskel.log file from the SD card to send me.
- To try again with another WiFi network, delete the ognskel.log from the SD card and edit the ognskel.txt with a different available WiFi network name and password.
Once you are successful in getting a diagnostics page:
- Notify Rob that the Pi is installed and booted, with the antenna connected.
- Rob will need to know the MSL elevation of the antenna itself.
- Rob will need to know the exact GPS coordinates of the antenna.
- Rob will then proceed with antenna calibration and OGN setup remotely.
- Rob will probably do that part of the setup on a weekday.
