Powering my mirror?
-
Ah ok, I also of one of these to fire an old Laptop LCD for a digital picture frame.Now we need to know the type of the LCD. You can write it when you’re back home and I’ll look at it asap. Probably tomorrow since it’s already 7pm here.
-
@MadScientist will this be on the back of the screen it’s self?
-
Here’s an example from my LCD that I am going to use for my mirror
The M240HW01 V.D. is the LCD model and AU Optronics is the manufacturer.
Btw, for the future: A V56 or V59 controller board are already available for less than 8€ incl. shipping and the firmware can be changed easily by USB. It has other disadvantages though, like not waking up automatically once the HDMI port is re-activated. -
@MadScientist wouldn’t that be the LTN170WX-L08 that i had to look up to find it? And thanks for the info on universal boards. Though I think I want the auto wake feature.
-
Yeah, I saw after I replied. I checked the datasheet and if I do not misunderstand the information, your screen should be at around 10W (max.). The board will probably take some, too. But you should be more than fine with a 30W power supply.
-
@MadScientist with the pi and all?
-
That should be enough for all if you don’t have more than the LCD, Raspberry Pi and the step-down module. You should check the power consumption of the LED strips, if you’re planning to use some. If not, you should be good with 30W.
-
@MadScientist
Will both the LCD and the step down wire to the same wire? Will this lower the 12 volts from the lcd? -
You split the 12V output of your power supply. One set of wires (plus and Gnd) goes to your LCD controller board (check polarity!) and one set to your step-down-converter, which is regulated to 5.1V for the Pi.
-
My point is that all the power supply’s under 80W only have one set of output wires.
