Monitor Audi
Objective: to make the electronics controlling the drive of a monitor from Audi — the driver of the motor. The monitor should be controlled by the button. Pressed — pushed, clicked advanced.
Monitor like this:
The mechanism itself proved to be very efficiently built, the housing and the cover and the base made of aluminum alloy, very good and compact design. The monitor does not swivel and it away. Opened blind — left of the screen.
The power mechanism consists of motor, reducer, shaft and frame:
On the shaft there is a gear with a spring — fuse excessive force. On the shaft of the motor has a rotation sensor. There are also two terminal end positions:
Total looms this scheme:
Motor, two limit switches, a speed sensor on the Hall sensor. This is enough to organize all the necessary algorithm of work and protection from wedge engine.
Draw a diagram:
From the drivers I have from the right only MC33186 — its and used. The driver is more than enough, the current consumption of the motor is not more than half an ampere. As the controller came ATtiny44A.
To position the printed Board in the housing, had to look for a place. The housing is densely Packed and the place is small:
But the place successfully has been done under the signet of this place:
The Hall sensor is connected in the standard scheme of a two wire scheme, so I use it inconvenient and I added a third Postings:
Next, attach the wires and you're done:
The place:
As a standard computer connector connector:
Algorithm:
Pressed the button — advanced. Press again — pushed. There are also two modes of operation: with the memory of the last state without. The monitor can be automatically controlled from the ignition switch. Also have protection against motor wedge and open limit switch. In the off state current consumption in half of a milliampere.
Job description:
and what is this idea, to introduce your panel?) it would be very convenient not all panels have where to punch the monitor, and here, and junkies are not attracted and the overall picture panel will not spoil. How much is the drive itself if not a secret?
let's reinvent, let's see, but from the limit switches or reed switches can not escape
Thank you! I recently own version of the scheme show. Say a ride or not. ;) Then choose the best one or develop one together.

Thank you! Interesting solution.
I have a slightly different problem: I switch on the ignition — monitor got up, turned off the ignition — otpustila. In such a case you have a scheme? ;)
just each scheme is done for each case separately, but the principle is the same with minimal changes

here look this might be better, if there is a wire that goes to the generator to hang on the castle should since you have to work

maybe there is somewhere in taloto, but it is possible to alter this or to fix it, we need to talk over it
Thank you! Interesting solution.

can I have a BJ see graph may suit yesterday Toko laid out, there is such detail two control inputs plus and minus sign to the outputs that go to the door activators to connect, was removed from the signaling regic got set he got )
although, your also interesting to look scheme )
Again surprised how well everything is done!Stepan Pavlovich respect and uvazhuha!
I'm also currently doing the rise of Pathfinder, but I did not like this level :( All Natalushko :)
It is not in your own car you plan to use. It's like buying a motor without a brain
Super! Very simple and native. Have been looking for such a solution. And could you put at least one part of this mech design? Would be a great help. Thank you.
No, after all the action with the MC completely removed the power — sleep mode no.
And the power from the battery to MK is supplied continuously, that is, it's just in sleep mode all the time while the key in the lock, no?
