Parker Lead Forming Topic Tools 3D printed forms 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 Stephen 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…
