Hacking Hardware Picofly - a HWFLY switch modchip

[nico77]

We already talked about this... Use higher diameter for the capacitors of the APU (Drain) and for the Source of the MOSFET.

Can enamel thin wire work for APU MOSFET? Sure!
How long enamel will work? Hope forever, though for how long do you think that a such thin wire can support passing high currents over 10A on each powercycle of the console? Look for the long term, at least 0.2mm or higher for those connections, for the Gate the enamel is ok, since it's only triggering the transistor.

yes, im still remember.
ill do just like dee87 mosfet . apu to mosfet 0.2mm, mosfet to rp2040 0.1mm.

btw
recently i practice soldering..., but i meet problem.

my "iron tip" solder is bad, the tip too long , it wont heat on the end/point tip.

i can melt the lead solder wire on the middle tip, but it wont melt on the end/point tip.
i need buy new tip i guess...

after that im gonna practice n pratice soldering first>
i wont touch my s~lite , before i can solder properly.
no rush

Read about this, but I can't find 0.2 wire easily.
However I think I've read in this thread that sata cables actually have that kind of wire. Is that true?

Use 2 x 0.1mm parallel
Its difficult and ugly but worked.

yep just like the origin Dee87 schematic

You may want to try thoroughly heating and cleaning the iron tip, then over-tinning it with solder to get a nice silver coating across the whole tip. Is it a variable temperature iron, or a fixed wattage that just "gets hot"?

I check soldering wire on mosfet
I think is ok
I try to oled switch using cpu flex from aliexpres
But i got the same problem
blue - cyan

you need to Install another 1 mosfet, some switch need 2 mosfet

I use brand new T12 for this, and the tip still a problem, but not as bad as my old tip.
Don't forget to always coat it with tin before turn off the solder.

Does that work by simply twisting two 0.1 wires together? lol

Yes, kirchoffs 1 law. Resultan of current goes in equal to current goes out. The current will be split into 2, 0.1 mm cable.

some kind of chips have already been mass produced in chinese market but no sign on aliexpress

Back in Nov/December 2022, we heard about this cheap mod using a Raspberry Pi Zero board. Naturally this took a while to be confirmed and it looks like the instructions are out and users are able to mod their Switch with few problems.

There is no chance I would be able to mod this myself, but there are sites/modders out there that could do this for a fee. How long do you think it will take before the process becomes easy enough for these Mods 4 Hire can mod my patched V1 switch?

Can't comment on SATA wire, I used AWG30 Kynar (stripped single conductor) which is approximately 0.25mm.

Only picture, can't purchase

Thanks! However he says he used four 0.1mm wires. Do you think he just went for an overkill or the more, the merrier? (Don't want to rip my caps off though)

...update...

..now getting Blue then PINK LED... checked CLK but seems OK (no shorts/bridges)

..tried to remove the RP2040 (including the wires on DAT0, CMD, CLK) but now Sw Lite won't boot

...Pink LED means "NS eMMC init fails, inoperative eMMC" or "Bad CLK"???
...are there any other instances that can cause Pink LED?

TIA

check if any wire touches the gnd

Thanks! will try to check....

@Phantomas77

am i bought the wrong mosfet ?
my mosfet sooo tiny ???
i cant even read the text hehehehhe lol

​

ant-man help!!
