Couple reasons: They're bound to be 10 times more precise than anything you and I can cobble together They have to apply for a lot of licenses and stuff to make sure it won't blow up/catch on fire etc etc It's really expensive testing and coming out with this kind of stuff on a commercial...

You misunderstood, I meant buy a valve, buy a servomotor... and... my schooling is failing me right now.. (can't think of the words) but... attach the rotor of the motor to the stem/handle of the valve, write code to control the opening/closing of the valve...

The project never wound up happening, I have a bit of code written, but I kept making it more advanced and more advanced, and never touched the hardware aspect of it, and found out we were moving this August, so I figured it wouldn't be worth it to extensively mod a house we weren't staying in...

Two manual valves that are turned by stepper motors behind the wall, I'll probably use a self-made coupler to couple them together, and an Arduino will control the whole mess, the temp gauges will be at the shower head and immediately before the hot and cold water valves. Why two valves...

Thanks, and meant specific heat... serves me right for trying to guess at something I'd read like four hours ago without rechecking it :/ Thanks for the help, now I have no excuses to delay this project anymore *grumble*

But won't it require some time to mix thoroughly? (Though I suppose movement will speed the process greatly) And what about all the fancy heat specific stuff for calorimeter's? Surely it matters (or not as much because they're equal anyway)

Useless explanation text: I'm building a shower system that uses motors to manually turn valves to adjust the temperature based on what the user sets I'm trying to develop a way for the system to preemptively predict what the temperature will be so it doesn't just say "Open hot valve a...
