A much easier way to do it would be to follow this guide. https://bitbuilt.net/forums/index.php?threads/analog-joystick-to-d-pad.97/ It is for an analog stick to a dpad, but I believe it would work for the 3ds slider as well.

I have an update here. I have made a couple revisions to my design. It is basically done, but i have a couple things to finish up. I have to wire up ground to my tact switches. I have decided to get rid of the battery setup. I am only going to use wall power. So I am about 1 day away from...

It might be possible with a not very good cooling setup and a small battery. It can definitely be done. But only the super advanced portabalizers could do it. I would never even attempt it. If you are asking for yourself, maybe after making a couple portables, then maybe. But if you are looking...

Not to poke any holes in your theory or anything, but I see a couple problems that might spring up when you are doing this. How would you just install wifi and sd card? The wii mini was made to run without them. So even if the traces are still on the board for sd and wifi, which i am not sure...

Just message one of the administrators. They can change it to whatever you want.

You definitely need to clean that back part of the gamecube memory card slot. Messy ports can definitely be the reason why it does not work. Also, there is some other stuff by the usb and video audio ports that should be cleaned up.

Since you have a rasberry pi 3, ps1 can already run fairly decent already. I know it cannot do ps2 emulation. That is out of the question. I am not sure about psp emulation, but the rasberry pi can do so many more systems. Rasberry pis are meant for old systems. Like 16 bit systems, and some 32...

Wish lies about the capacity of their technology, whether it is batteries or storage. I wouldnt trust it. Also, the storage is slightly above a third of the 18650. If you are going for small form factor , then you should do some research with lithium polymer batteries.

It is possible you shorted the video line on the chip to a voltage line. If you did that, there is nothing you can do. The only thing i can suggest is that for your next one, keep everything clean and take it slow so you dont do anything wrong or mess anything up. Also, if you are relocating...

After looking at your wiring, it looks like some of the exposed ends are touching. If you could desolder all the wires and take a good picture, we might be able to help a bit more. Those pictures are a bit hard to go by. Also, did you run power to the board before you cleaned the board? You...

It wont fry unless you run power through it. As long as you have not done that, all you have to do is clean up the board and get rid of all the shorts and it should boot up fine. A cotton swab and some isopropyl alcohol are great for cleaning computer boards. Just make sure that no metal spots...

Look what came in the mail. A couple pieces of perfboard, 2 pth regs, a small screen amd driver board, ds buttons, altoids, some nice solder, and a game code for nuclear throne. Thanks Deonaught! All this stuff will be super useful for my next portable.

5v is great too. I just have a hunch that the voltage regulators on that board are not very efficient. So if we could bypass another component, the watt usage of the screen and board will go down. If you have the screen with you, could you measure the current going to the 5v input? That way...

So did anybody ever figure out if this screen can be run off 3.3v? And did anybody find out how many watts this runs at? Because if it could run off 3.3v, that would be very convenient, and more efficient because it doesnt have to go through another voltage regulator.

It is definitely possible to make an original xbox portable. But the power consumption is so much that you couldnt put any batteries in it. I think those create a lot of heat as well. So, the cooling system would have to be very well designed. I am not going to say its impossible, but it is...

I am not entirely sure what you mean by solder pads, but here is a link to the gpuo pins if that is what you are asking. https://www.raspberrypi.org/documentation/usage/gpio-plus-and-raspi2/7 And this picture shows how to wire an external sd card...

All this sounds great. I just have a couple suggestions. First off, if you are using 2 batteries, they have to be in series to get the voltage you want, they cant be in parallel. Second, with "buttons" you use these things called tact switches. There are 4 legs on each switch, you then solder...

That one says it is a battery management system, which is good. But there is no proof in the specs. I would try it out and see how it works. It will most likely work just fine. Just make sure you are really careful with your batteries. We dont want anything to happen. Just solder very quick...

Do you have a memory card with FreeMcBoot on it? That is the thing you would want to use. It lets you load ps2, ps1, and some other types of games off usb. Just out of curiosity, why are you keeping the disc drive?
