Best thing to do with a $30 raspberry pi?

I ended up offering $30 for this Pi and the seller accepted

• 900 MHz quad-core ARM CPU
• 1 GB LPDDR2 SDRAM
• 10/100 Mbps Ethernet
• Only 5V

I already operate a server and run these

• B-Cash Full Node
• Monero full node (Still syncing)
• Crafty for Minecraft hosting and management
• Python backend for app
• OpenWebUI & Ollama.

I know the Pi's specs are low (especially ram) but I couldn't turn down the price of CA$30. Any ideas?
