I'd like to see something like this where all the smarts are located in software running on a PC connected to the box via USB. The hardware and firmware in the box would only be responsible for sending sense data to the PC, taking control commands from the PC and doing the low level PCM output to the heaters. The software on the PC would have a user interface to change settings and display graphs over time of temperature, relative humidity, dew point, heater output, etc. Oh, I suppose the box could also have a manual mode where everything was controled by the box if/when no PC is connected.
