Thanks for the answer, I feel stupid, I thought it was AA sized li-ions that would be 3.7v but it is usually not the case. However, it is for regular 18650 3.7v cells. So there should be no trouble at all. I might loose a bit of power due to the step up to 5v I guess though.

Thanks for your answer, first of all, I have 4x 3500mah 18650 batteries and I just want to use the board. I initially wanted to buy this, https://fr.aliexpress.com/item/32951183391.html?spm=a2g0s.9042311.0.0.27426c37wd7baW. I could go for a more expensive solution but it's a first project and...

Hello, I am making a portable wii and ordered a battery module from aliexpress that never came. I have a battery pack one and I wanted to know if it was ok to use it instead. It's a case for 8 AA type battery they are all in parallel. The output is 2 amp. I guess I could also use directly the...

Oh thank you very much, I will take that.

Hello, I'm looking for a small amplifier. I heard that the PAM8405 was a good inexpensive board. I looked at it and found that: PAM8405 with wheel control Initially I thought that it was a good idea, but it looks quite unpractical to mount and could interfer with other things. I would like to...

Thank you for your answer, I guess that the flx in 5V is enough? Or do I have to take the 5v max speed?

Hello, I think cooling my portable wii may be interesting. I thought of a few idea to do so. The easy one is using the original cooler, maybe bent the heatsink fins and add a fan. I have this laptop cooler too that would have a good enough fit after modifications and may be cooler that using...

Yes of course, my alternative would have to use the micro usb power line only for the detection on the MUX and not using it for another purpose. It's already directly connected to this IC so I don't think that if there is a risk, it will be bigger. However I can understand that this ic is...

Ok, thanks, reading the schematics, you use the mux to switch between the power supply and the dual fet bus switch to switch the data line. This one is specified for USB application. I don't know if I am right but the VCC is connected to USB_5V that could be lost while the mux switches the power...

I would like to know what where the issues because you use an other ic for swtiching the data lines if I understand it correctly, isn't the mux just for the detection? (since I'm not a student anymore I can't find a free program to open the .sch files)

Thank you, I will see that.

Thank you for your answers, I was aware of the voltage hazard, this is why I would have switched only the data lines and keep the vcc and gnd from the battery. After reading this guide I think micro usb could be better.

Hello, Since I don't want the drive to be outside the case and I'm not sure of my ability to do an easily openable wii portable, I wonder if I could use an USB-C connector. My idea is to switch the data lines of the usb drive between the motherboard and the USB-C connector using 2 mux and a...

Since I can't find the USB drive samsung fit advised on the portabalized BOM, is there an alternative? Does the new one in usb 3.1 will work fine?

Thank you for your answer. Since I don't have any cable and I've read many thing about buying all awg 30 to 38 magnet wire, is there a size that is ok for everything? In the portabalizing BOM there is only awg 34 wire so is it enough? I guess I should take multistrand wire for it to be more...

I found the L7009 in china for $39.48 at the moment. I don't know if the source is trustworthy but if you are not from US it may be a good offer. https://www.dx.com/p/l7009-7-0-tft-lcd-screen-car-reversing-rearview-monitor-w-vga-bnc-av-input-stand-black-2045069#.XPgVE71R0uU

I looked for screens, I found the one that is said to be the best one in the Portablizing BOM for 40$, https://www.dx.com/p/l7009-7-0-tft-lcd-screen-car-reversing-rearview-monitor-w-vga-bnc-av-input-stand-black-2045069#.XPgVE71R0uU I found another one with like 15 rebranding for only 22$...

Ok, perfect, so it will serve me to switch between screens aswell.

Thank you for your answer, I will see for a better screen once I've tested that one but I think it will be bad yes. I assumed it was directly composite since I always used a composite cable with my wii. Since there is a relatively easy mod it looks nice. I guess I can put a awitch on the 3v3...

Maybe I should look at screens from another source, but since I'm in Europe I'll have to go directly to Chinese website so it is quite a bit long. Is there a guide for good screens? I don't even want to cut my original GameCube controller so I guess I'll end up using a cheap clone.
