Sorry, i'm talking about the GBO.. the gray brick..

for LSDJ i wanted to add a backlight. It is deffinately doable.. it just sucks.

Weird.. what NOAC did you get?

Regardless, open 'er up and see if there's any power regulation.

Klefmung wrote:AAs are 1.5v a piece. >_> 6v? Wtf. it is 3v... but since the voltage is higher, maybe 4.2v?

There are 4 AAs in a gameboy. So 6v.

4 x 1.5 = 6 still, in this modern day and age.

I'm referring to the original gameboy of course, about which we were arguing if a backlight mod is feasible.

Yep... a good 6v will slam out some serious 10,000 mCDs!

did you measure the voltage when it was under load or not?. the voltage drops sharply with load, the rated voltage is what it should be at the rated load. ;)

Oh i see, you're asking if i checked what the voltage was under load, not misunderstanding what i checked.

No, i didn't check it. I guess ...

I didn't measure the voltage at all.

I measured the current. You can only measure the current under a load, because the load is drawing ...

Also, it's important to know how much voltage the parts of the NOAC can tolerate. If you provide TOO MANY volts.. you will burn out parts of it. Like popping a 9v SID 8580 in a 12v SID 6581 socket.. zoooop, burnt.

Generally, these things are voltage regulated. Opening them is the only way to know ...

it can be backlit, jsut not well.

No. It can NOT be backlit. The light will not shine through at all.

Sure it will. LCD screens are transluscent, meaning light passes through. In the case of the gameboy, it's a question of removing the opaque foil from the back, leaving only the transluscent ...

hmm. how are you going to make a portable NES without opening the screen?

Check to see if there are voltage regulators in your screen. Could be that your screen needs precisely 9 volts, so has a 12v adaptor in order to feed the 9v with enough juice to regulate down.

I don't remember, but doesn't th enoac run like a NES< on 5v, even though the adaptor is 9?

Also, just ...

Let me expand on Vb's answer:

YOU CAN NOT DO IT.

It is impossible to backlight the GBC or original GBA. The colours wash out and such, plus there isn't much room. They can only be front lit. Buy an afterburner kit or (for about the same price) an SP with a "backlight". It's acutally a front light ...

I have a little more. I KNOW the problem is caused by overvoltage, I just didn't realise the Transformer was outputting 10.3 volts when it's labelled for 7.5.

My question is, if I lower the voltage to a normal amount (under 8v), will it be fizxed or did I fry something?

the only circuit that ...

I am looking for any easy guide for placing LEDs on the inside of my GBC or original GBA

Anyhelp would be nice thanks!

PS. I want them inside my screen so they are backlit, no outside (did that with my original Gameboy)

I tried that.. but it barely worked. I couldn't really see much other than ...

The PSU for the psone screen says 3.0A..

how much is ACTUALLY used.. and how much is actually used after the white LED mod?

I need to know if it's low enough for me to build a little circuit to draw it's power directly from a commodore 64 power supply, or what... .
