Let me know if you need help :cheers:

I will when needed, first need to buy this pcb for the servo, when a deside to, is that it and possable? :applaud:.
i'l show you my schematic verry oldscool.

That looks like it could work for stop positions. You will still need a Pololu controller to control the servo directions, speed, etc.

Yes indeed for automatic rotation i need something like pololu ctr.
but now it's done manual, with a switch and two potentiometers these are controlling the 555 timer.

Ah I didn’t understand, I thought this was what you are planning on doing, not what you have already done.
gumpie:
Right now it works , only i was searching to make it goes automatic when the screen change,
and the way you make it is very clearly.
You made a Greate tutorial :cheers:

Wonderful tutorial! :applaud: I just find the D645MW a bit expensive (mounted, etc.) but the alternatives are immediately more complex to set up...
I have just one question: what are the magnets for? They serve to help the screen to stop at the right place without bouncing?
Thanks !

Sorry I was busy all weekend. Yes they do two things, act as a support for the weight of the monitor, and help to slow and eventually stop rotation more accurately.
The monitor is heavy enough that it kinda wants to bow the two plates down so that they are no longer parallel. The magnets support the panel closest to the screen so that the two plates stay in parallel.
The servo actually does have targets that you set to dictate where it will stop, but if you move really fast then when the servo tries to stop, the momentum of the monitor wants to keep going, so the magnets help to slow the servo down as it gets close to it's target (end position), and helps to keep it in place so that the servo isn't expending energy to maintain the position.
Hopefully this makes sense, it's kind of hard to describe.

Thanks, I understand :)
I found a 32" TV, the weight seems OK to try your tutorial ; but I have a little problem I think, the VESA holes on the TV back are not centered...
They are OK horizontally, but vertically, I have :
19 cm - first hole - 10 cm - second hole - 14 cm
So, when the screen will flip vertically, it will be more on the right (or left) but not centered... Any way to resolve that ? It's a 200x100 VESA, I can find a plate with these dimensions, but how make it centered when it rotates ?
Thanks !
