Controlling Electronics with Ruby
summary
Ruby controls electronics using serial‑attached devices: Firecracker CM17A (X10), BetaBrite LED sign, Arduino with XBee radios and rad Rubyuino toolchain. Key specifics: serial at 9600 baud, CM17A plus TM751 transceiver for power‑line X10, BetaBrite requires memory allocation before writes, a 1s sleep after sending, and at least +4 bytes padding. XBee current is 45 mA active / 10 μA idle (CR2032 ≈25,000 h idle, ≈5.5 h continuous transmit). A CI notifier reprograms the sign, flips LEDs and X10 modules and works live.
