- 17. German Would Love Insight Into: • Hive Temperature • Hive Weight • Outside Humidity • Outside Temperature 17
- 19. Challenges: • Open to the elements • No power • Very Limited Budget • Must be easy to repair/maintain 19
- 20. Challenge #1: No Power
- 22. Issue #2: Limited Budget
- 23. Solution: 1. Raspberry Pi (first 3 were free) 2. Raspberry Pi specific devices (free) 3. SD Cards (3 for $20) 4. Wire/cables (free) 5. Temperature Probe ($8) 6. Solar Setup ($140) 7. Macgyver like ability to figure out solutions (free) 23
- 24. Not perfect but we have a start. Including twitter.

- 50. I'm using Ruby and Sinatra
- 58. Other Stuff Used • Phusion Passenger • isc-dhcp-server (linux package) • hostapd (linux package) • iw (linux package) 58
