Rotating monitor construction *Project finished*

--- Quote from: Cornchip on November 04, 2007, 09:51:53 am --- Wow...this is looking more interesting. Does this allow me to keep the switch 'as is' and have the ability to auto rotate using koz319's software? (provided you don't try to use the switch and H Drive at the same moment). Is that what the diode is for...to prevent the back flow of current? Also...is the pdf file from koz319's link the exact screen to make the H Drive with no changes keeping my switch? I think I might just be able to get these parts local to where I am and avoid Digikey.

I guess Koz319 would be better to answer most of your questions.
But I can see where you could use the computer AND your switches to rotate monitor.
Although the simpliest method would be to add another switch for manual (your switches) or auto (computer). Otherwise your computer outputs might conflict with your switch positions.
As for the diode, are you referring to the 5K ohm resistor?
I didnt use a diode in the last diagram, but the 5Kohm resistor is just to protect the H drive inputs by limiting the current flow. This resistor may not even be necessary.
I just havent tried connecting A or B directly to positive because I just didnt want to take the chance..
Cornchip:
Opps...I modified that last post. I thought the resistor was a diode. Could a diode protect the computer should the key switch be used at an inopportune moment? One other program that I rotate (Kawaks) would still have to have the switch....or any other emulator not supported. Also I have a Dreamcast that has a few vertical games as well (my monitor has 2 VGA inputs). Hmmm....

DaOld Man:
Here's another crappy paint picture, showing a DPDT switch to switch between the computer and the SPDT switch:
I just squeezed the extra drawing into the first. if you are interested in doing it this way, I will draw a better picture.
The Auto/Manual switch is a maintained switch, it could be hidden somewhere, such as on top of cabinet, or in back, or you may want it next to the SPDT switch.
Cornchip:
That's alot to think about. I think I'll build this on my bench first and get the wiring straight before attempting a re-wire of the cab. Thanks DaOld Man for the help.

DaOld Man:
Good luck, just remember to be careful when wiring up the H drive, if you get something wrong, it could fry the transistors.
Please keep us posted on your progress. it might be a good new thread.
