Programmable Temperature Cycling Shower

get clean and awake in the minimum amount of time

Hot showers are relaxing and are the best for cleaning. Cold showers wake you up the fastest and for obvious reasons take the least amount of time.

The Thermal Cycler is placed at the join of the hot & cold water pipes after the standard mixture control. Mechanical in nature and powered by water pressure, the device is engaged after the "base" temperature/mixture is set by the user in the normal fashion.

What it does is to change the hot to cold ratio of the shower water in preset or user-set patterns.

A typical early morning program might be a 4 second cycle consisting of 3.5 seconds of unmodified flow followed by half a second of ice cold water to the recipient: stimulating *yet* not a long enough duration to be overly physically or mentally debilitating. This would speed up the process of wash/rinse first thing in the morning by quite a bit for a near-somnulent occupant.

Another program might be a 10 second cycle consisting of a half second "very hot" shot followed by 3 seconds of cool then 6.5 seconds of unmodified. This would open the pores for cleaning without the expense/time of a sauna or the discomfort/potential-damage of a longer duration of hot water.

ok.... bun the hell out of me :)

       My shower tends to do this already.

       This was preheated in an old Man From U.N.C.L.E. book I read as a boy - Napoleon Solo was boasting of his new shower that did just that.   

       It must have been a complex mess of gears and hydraulics, since the story predated computers. Then again, washing machine tech was not too messy back then.

       //must have been a complex mess of gears and hydraulics//
I don't remember that episode(s) but this isn't very complicated: I can easily imagine a preset one where you pop in a circular cam-disk. For user=-programming I suppose you'd have to be awake and do it in advance: a malleable cam-disk with 2 rows of extendable thick pins radiating outwards to nudge itty-bitty levers that control the flows.
  

       and who could possible bone this ? -_-

       I did. I want a constant temperature, the same every time, and I don't want to have to fiddle with anything to accomplish that.

       moot since the default is "do nothing".

       I would like to anonymously control the showers of other showerers, changing the volume of water, temperature and the nature of the stream to maximize their cleanliness, godliness, moral education and intestinal fortitude.

       sounds painful

       [bungston] then mount one on your toilet fill-line.   

       I recall an apartment super who used to cut off the hot water when the rent was unpaid.
