Rotating monitor - Yet another take
psychotech:
Hello..
So many awesome rotating monitor projects going on at the moment. Great software controlled stuff, etc. U guys rule!
So, I just had to try and build one for myself too ;) It's just that I can't code worth **** (PHP/MySQL/JavaScript/etc. won't help me here..). So, gimme a semiautomatic and away I blow!
One thing though - might be I've missed too many threads - is that quite a few of those older great implementations haven't been too closely documented? Yes, I know, this is not that good a document either but if anyones interested, just ask for more info and I'll add the info to this thread.
(Semiautomatic? With a simple ON-ON switch you make the screen either horizontal or vertical. Simple logic. Even I can do this..)
So..
Here's my take at a (semiautomatic) rotating monitor.
---------------
Thanks to weisshaupt & Cornchip for documenting their builds ..Awesome ideas & great sources of inspiration !

Alright, it's some kind of a hybrid: semiautomatic LCD rotation with friction drive. (Still waiting for a suitable bicycle chain/wheel combination to come my way:) )
Some leftover MDF, wire and 2 microswitches and it's almost done? Add a DPDT switch (ON-ON) and it is.
! The bearing for this version is taken from a 165mm diameter wheel (2.95 €), 46mm deep, and is inserted/mounted in a hole drilled through three layers of 16mm MDF !
(Almost) everything in these pictures is actually upside down.. Keep that in mind ;)
12 pictures, you decide..
And it goes like this:
01. 19" HP LCD facing down with a 16mm MDF plate on top.. Four wheels to add some friction and small "L"-brackets to trigger the microswitches..
02. Closer.. Zebra wheels to help me ascertain theres absolutely no give/play in the bearing/mounting .. The actual mounting plate goes between the two spacers...
03. Another picture of the same stuff. And yes, it would work even without the wheels. There's no "play".. It's just that LCD's don't weight enough..
04. The LCD plate's axle goes here. So, it's the bearing with the microswitches in place and all wired for action. (Hey, this picture is from up ..so, actually just right......)
05. The wires from the switches seen in the above picture go to a "terminal strip" (whatever, it's a "sokeripalaliitin") .
06. The main mount seen from below. Motor up. Metal reinforced bearings center...
07. A closeup of the motor sandwiched between two pieces of 18mm pine (the motor is just about 18mms.. useable info..). The almost intact L-bracket secures the motor in place..
08. Well, it is upside down in the picture. And the "motorized" side stays in place.
09. Another angle of the same solution. And working like a charm.
10. Well, tried to take a picture of the solution. Hope it at least gives you ideas :)
11. Overall.. With the main Vertical/Horizontal switch in the picture.
12. Not "too much" slack in this implementation...

Yeah, I know, now I only need a cab to use this in...
..............?
Questions, ideas, etc. ?
weisshaupt:
Hey Psychotech,
Nice Mount.. much nicer than mine. Glad to see my hours of cussing that the thing and almost giving up yeilding some positive benefit for others..
If you want to do automatic, the little program I wrote for use with a Parallel port SHOULD work just fine with this..
you just need to isolate the Power from the leads coming from the PC using that cute little secret motor driver..
iThe program is posted in my Ghost in the Machine project thread if you want to try it out..
Good luck and keep us posted on the progress!

very nice engineering (",) i believe my machine fits your deinition of 'semi automatic'
heres my highly technical schematics:

Awesome stuff. This looks pretty simple. Any chance you can post links to purchase the parts (switch, motor, drive wheel, main bearing, etc) for others to copy? I'm assuming you picked a motor which doesn't turn at hyper speed and can handle the heavy load, so you didn't have to deal with slowing down the torque?
Thanks for sharing! Still the missing piece to my project as well!

Could you post wiring schematics too?
