README
Readme.mdSmart Cat Feeder
A smart cat feeder, an "upgrade" from the feeder on Thingiverse.com, using an ESP32-S3 Dev board -- a more powerful processor. It will have a touch screen, and provide a web server over WiFi. It will use a load cell to measure how full the food bowl is, it will have a sensor to check when the food bin is low and have a battery backup to operate in the event of a power failure, to insure your cat will be fed when the power goes out.

Questions
How big is the ChargerAndPowerSupply PCB?
It measures 111.8 × 71.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ChargerAndPowerSupply use?
24 parts, built around the LM317KCS, VO615A-6 and KBP301. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the ChargerAndPowerSupply KiCad files?
From the RobertPHeller/SmartCatFeeder repository on GitHub, at the commit this page was made from: the board is ChargerAndPowerSupply/ChargerAndPowerSupply.kicad_pcb and its schematic ChargerAndPowerSupply/ChargerAndPowerSupply.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ChargerAndPowerSupply design in my own project?
Its repository states no licence, so its author keeps all rights: ask RobertPHeller before reusing the design.
