    • Best practices?
    • Cat Feeder Unreminder
      • Choosing a solar panel
        • Solar Panels generally act like a current source across its useable power band
        • Specifications that are important
          • Power (Watts) - Max
          • Current @ Peak Power
          • Voltage @ maximum power point (Vmpp)
          • Vmpp - Voltage @ open circuit (Voc)
          • AEM10941 Solar Panel Chip
            • Max V is 5V so open circuit can’t be higher then this
            • MPP is set by 2 configuration pins
            • Ratio between Vmpp / Voc

              • Voltage References and dev boards
                • MCP1501T-20E/CHY
                  • 0.1% initial Accuracy
                  • Low noise
                  • worst case 50ppm across -40 to +125
                  • Capable of sinking and sourcing 20mA
                  • AD584 Dev board
                    • 0.3% initial accuracy for the J version. The K version is 0.1%
                    • Linear rail is shitty
                      • Got 300 mm of knock off chineasium linear rail
                      • Sounds like sand in the bearings
                      • Held vertically the blocks get stuck…
