Hacking Hardware Picofly - a HWFLY switch modchip

this is gonna be the way im gonna go for now .
till we get a smaller board

I had to cut a window for my Trinket M0. Been running that way for years now w/o issues. I did put some Kapton tape over the rough edges because I take apart all the time and don’t want to get a sheet metal metal cut.

Why are there wires running across the fan? Is that just temporary?

what's the part number of the mosfet?

Data sheet for that IRFHS8342 chip:

How about combining it with the flex cable into a single pcb?

My brain is way too smooth to do flexpcb design ngl. plus Putting the logic components on a flex pcb will increast cost substantially. I want this to be a cheap barebones board that does the job well and it makes sense to take advantage of the existing flexpcb

Maybe collaborate with this gentleman?

what's the part number of the mosfet? or rather, what's the part number of a mosfet that is compatible but not a nightmare to attempt to solder?

OOps, didn't see your reply, binkinator. Thank you.

Wait... you made this in a DAY?!
You circutboard people are bonkers fast

It was my procrastination activity for the day lmao. Also i had a head start as i've been using the RP2040 in other projects too and had a working skeleton design to use. I do want to emphasise it's not finished yet, still got the routing to do, but most of getting a good circuit design is in the placement, good placement makes for very easy routing.

I might get protos in hand in a week or two, assemble when i can. My switch is unpatched erista so i might build a few and see if there are people willing to test it. Can i ask on this forum for testers? i'm not 100% sure how modchip designers do testing with users as this is my first console design, usually i do much more boring stuff haha

okay guys no dont give me hate i was thinging about how we could still be able to update the rp2040 zero even though we shouldnt have to and a remeberes a flat cable in the ps4 controller that i once used for a usbc port where someone riped the traces off under the usb-c port in the switch ..........
well here u go

Did you tack it down and test it or is this just mock-up For now?

ORDERED USB-male finger style. CHEAPEST one on AMZ since they deliver it tomorrow

Too thick..

i reflowed it straight to the board ill will build an adapter in a while and do some testing butt it should work since its for the usb connection of the ps4 controller

J Tip

You mean I tip?

 

[wscp]

btw, this should technically work with even a normal pico, right? I know it won't fit inside the switch, but as long as the pinout is correct it should work? Of course, the firmware probably wouldn't work due to the board being different...Though I don't see a big reason it wouldn't either.

Notch the backplate for the wires and tape that pico to the backside. Solved.

normal pico doesn't have all the same pins broken out afaik, missing GPIO29 as it's connected to an internal temp sensor

although if you fancy yourself with the soldering iron you can remove the temp sensor and solder to the pad

At that point, I'd probably be 3d printing a custom enclosure.

nop, the type of the tip for the soldering iron is called "J" tip

Ahh, didn't think the zero would expose a different set of pins...

 

[tecfreak]

make it picofly, at least

Yeah. Why is this thread still called "Pikofly" and the AIO thread as well instead of "picofly"?

@Modzvilleusa just posted a video on Pikofly.
