hi everybody! i've opened this topic to show you a cool mod i did some months ago, everything started just as a random experiment, but the result was better than expected!
i was having fun recovering smd-leds and reflecting layers from the broken lcd of my big brother's mp4 (cowon i9, smashed after 2 weeks), then i had an idea, slap them in a vmu and see whats happens.
this was the first test:
to do that, i've carefully removed the silver layer in the back of the lcd wich is needed to reflect ambient light on the vmu's screen, so you can see in it. i had to remove it because it denies the light go through itstelf. Without it, the vmu screen is totally transparent like glass (just slightly bueish)!
so, i've cutted the reflecting layers to fit perfectly behind the vmu's screen, and added smd-leds:
in this early attempt, leds were wired again to the original source in the mp4 player, that's how it looked in the first photo i linked, it was really promising!
then, when i had figured out the correct voltage and current, i've soldered leds in parallel inside the vmu, and soldered them to pin 14 (3,5V) and pin 8(gnd) i've added a 180ohm resistor to lower voltage to 3V.
then, the first attempt where power was supplied by the controller itself:
accidentally the led in the middle was soldered bad, and it didn't light up, but it's fine now.
here an other shot while the controller was disassembled
before the mod, i tought it would looked greysh and faded, but it's a lovable solid blue!
