Very nice build! Are you using a 640x480 screen? I love the orange case!

Alright using a composite cable I was able to get 2 of my 3 screens working. I have only tried wiring things up like the image from the wiki. I will try your solution tonight. My solution seems to make the screen run pretty hot. Does this board get very hot with the other technique in the wiki? Can...

Does anyone know how to reduce brightness level on the screen? I reduce it to 0 through the display's button pcb but it still is too high to play at night. Also the battery will last more time, I think could be interesting. Any thoughts? I tried this on my BW screen with brightness reduced to 0% bu...

So I happen to have a number of 5v to 12v DC-DC step-up converters. Can someone smarter than me explain the pros/cons of using this to power the screen at the expected 12v, as opposed to modifying the screens? I am assuming you'd be losing efficiency on the step-up and there's probably already a st...

I tested a 3.3v power supply directly connected to the 3.3v output and screen works fine but as i suspected the chip amt630 still gets hot and still consume the same current.

The regulator is config based. ie resistors and capacitors connected decide the output voltage. I think it is "a5269". BTW your board has a single step regulator. The second one is a EEPROM and not a regulator. If you supply too much voltage to that you will damage it beyond repair. If you have a m...

It uses AMT630. Here is another image

Based on this image the board just seem to have one regulator. It just takes 12v and turns it to 3.3v. Can i see closeup picture of your board's regulator so i can check the datasheet?

The BW boards i have each have 2 regulators. One 5v regulator that takes 12v and turns to 5v. The other one is a 3.3v regulator that takes 5v and turns it to 3.3v.

You connect 5v to 3.3v regulator's output and not input. that is going to AMT630. so you are sending 5v to AMT630. How are you not getting this. No no. 5v supply is connected to the input of the 3.3v regulator. As i said only 3.3v is being supplied to the amt630. I double checked it with a multimet...
