Episode description
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
- Choosing a solar panel

- 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%
- MCP1501T-20E/CHY
- 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…
