About Life, Robots and Cats!
summary
Builds a home pet feeder called Sasha that dispenses measured portions on schedule for two cats using Raspberry Pi Model 3 and Node.js with johnny-five + raspi-io to drive a servo chosen to handle 3.2 kg loads. Scheduler initially misfires (releases food hourly) then is fixed; feeding runs twice daily. Adds an email trigger via an NPM package called main notifier and plans a Telegram bot. Entire project compiles to about 42 lines of code and the device works.
