I worked (and am still working) on my Nixie tube thermostat for my heater. Though it will have 4 relays for controlling anything. I only have a heater (radiator), I am using a PID controller to regulate the temp. Cooling will just be a standard stupid algorithm, one tested by turning on and off a room AC.
When I get a chance I will post more details. I am hoping to have a kit before next winter :) We'll see ;) -joe On Thu, Jan 15, 2015 at 7:36 PM, barnbwt <barn...@hotmail.com> wrote: > I actually got into the hobby over the holidays, as a break from > wood/metal working out in a cold garage.
