I'm thinking something like a dairy milking machine turned right down and outfitted to auto start by a moisture sensor....
The design is still in conceptual phase.
Oh no, you stop right there, this reminds me of a joke I use to tell as a teen, about a.......... well.... let me tell the joke lol.....
Ok, so guy breaks down on the side of the road out in the country. He starts walking, realizes its late, sees a farm, and asks the farmer if he can stay the night. Farmer says "ok, but ya have to sleep in the barn, and dont stick your dick in the three holes in the wall". Dude says ok, thinking nothing of it. Later in the evening, his curiosity gets the better of him. He sticks his dick in the first hole... oooOOo, that feels good! He then wonders what the next hole feels like..... OOOooooOOOooOOO!!!! Even bettter!!! So now hes thinking "I wonder what the THIRD hole feels like!!".... sticks in the third hole..... "Uh Uh UUUHHHAAAGHGGHGHGHGHG!!!!!! GET IT OFF MEEEEE!!!!!!! FUCXK!!!!!! AAAGHGHGHGHGHG!!!!" and finally gets his dick out! Farmer runs in, sees what has happened, and says "I told you not to stick your dick in the 3 holes!". Dude asks "WHAT was in that third hole!!!". Farmer says "Wellllll, first hole was a young calf, second hole was an old pig, and the third hole was a broken down mild machine that didnt stop til it got 600 gallons".
So no, I do not trust electronics to perform as they should lol.
