Baby room thermo/humida-stat

To keep the baby room spot-on in temperature and humidity, I built a circuit that controls a low-temperature radiator and humidifier through a normal thermostat. It uses a relay with a 24V milliamp control line and an ordinary wall mount thermostat to control a 15A 120V outlet that runs the thermostat and the humidifier. This lets the baby room be on its own closed-loop.

Moon Dimmer

I also made a dimmer box for a Moon lamp that my wife got at Ikea. It uses a UL dimmer switch wired into a standard outlet in a stand-alone box, so any incandescent lamp can be dimmed. We like to dim the lights while we put baby to bed.
