Stories of Troubleshooting the Raspberry Pi
Some of the limitations of working with a Raspberry pi are:
- The size of the SD card you use, we used a 32GB card for wiki4print. This will put limit on what you can put on your pi.
- Connectivity, ethernet is always the better option for stable network connections. Using mobile data or wi-fi is great, but once you need stable access, use an ethernet cable.
- Heat! If the CPU overheats the pi can freeze / shut down processes
During the month of January we were plagued by 502 bad gateway errors indicating that the pi was down.
This was partly due to poor internet connectivity at the location where the pi was in London, an art studio in Woolwich.
We also later discovered that it was also due to the pi overheating. This discovery was confirmed once the pi was moved to the house of an In-grid member where it lived under a bed for 1 week in January. This problem was solved by adding a heat sink to the pi which also has a fan that pulls cool area past the CPU chip on the pi 4B [see centerfold image].
After the addition of heat sink the pi has been stable. Ethernet connection at HKW has allowed us to access the pi via the Servpub VPN for the duration of the Content/Form workshop 29.01.2024 to 03.02.2024
