Remote Appliance Controller

Well recently my mom asked if I could build an electronic device for her. Out in her shed my step dad built some mangers for our dogs (one of my dogs just passed away unfortunately) in order to keep them warm during the winter. They have woodchips, insulation and haat lamps over them to keep them warm. Every time my mom wants to turn it on or off she has to go all the way out to the shed. My plan is to build a device that will allow her to remotely control the lights (and radio they have plugged in for the dogs).

So far I have worked on the controller/receiver board and am almost done with the PCB design. I have altium at my job and they let me use it when I want so I decided to do this project in altium in order to get a better handle on it.

This design uses a transformerless power supply. I decided to use a TI MSP430 microcontroller and a Microchip MRF49XA transceiver chip that I plan to run at 433 MHz. All it needs now is some mounting holes and a proper antenna (probably going to do some kind of onboard trace antenna).

I will post the transmitter PCB soon and the schematics for both.
