Automatic Toilet Flusher

[skimask]

Well I do want the simplest
but I don't have very much money either.
I have a book that kind of describes what I want to do but it is in assembly or c,
I can't tell but it's not in basic.
What would you describe the level of difficulty of the programming going with the cheap option?

A momentary switch bolted to the door frame connected to a solenoid that throws the flush handle and/or lifts the trap at the bottom of the tank.
Door opens one way, it brushes the lever, but it's the wrong way to close the contacts. Maybe the lever is on a one-way hinge so it can flip the one way without a problem.
Door closes the other way, it brushes the lever, and it's the right way to close the contacts.
The solenoid is bolted to the wall behind the toilet. The arm of the solenoid is connected to a cable that pulls the trap at the bottom of the toilet tank.
Use a solenoid like one from a trunk release of a car, or door lock or something...anything.

I think that's about as simple as you can get...1 12v battery pack + small charger, 1 level switch and attaching hardware, 1 junk solenoid from a salvage yard, some wires and a piece of cable.

No programming, no PIC, no nothing, just a bit of hardware...done...
That and kicking your roommates square in the ding-ding.
I mean, that's just plain nasty...

What if, Techbuilder’s next step was to get them to close the door…

Oh....now that's just nastier...

How about the foot switch? Gotta step in to step out....

lol you guys are nuts

I just want to flush the toilet by moving my hand across the IR beam
and the servo push the handle down.

If I used a car solenoid it would break the handle of the toilet
lol

and I don't want a whole bunch of messy wires just something plan and simple.

If I put wires up connecting from the door to the toilet there just going to take it down when we have guests.

lol

No one has a solution

electronically? lol

I am surprised you guys haven't said to attach a cap to the door knob and if they don't flush the toilet then IR receiver sends the signal to power the transistor to charge the cap, and shock them when they touch the handle.
lol

Good Idea though

I just want something clean

Hi Techbuilder,
Your problem is not technical, it is more a matter of hygiene training, essentially political. . .
some people train dogs by rubbing their nose in it, you might try that either directly, by giving them a whirl or indirectly by putting up a board with their names and stars and sad faces, and make sure everyone sees it!
