Hacking Hardware Picofly - a HWFLY switch modchip

[EM1_1]

Nah pi pico is too big.

Oh yes, I forgot that the RP2040 Zero barely fits

 

[Dee87]

If its not too much trouble, could you point to that sensor to remove please? I Assume gpio29 is adc-vref.
I only have pi pico atm. Waiting on a zero and want to test it out.

this should be it we had this discussion a few pages back

Is seeed rp2040 compatible?

 

[detilmalala]

The current fw is meant for the rp2040 zero because of the LED. I bet the fw will still work on a Pico, but maybe the rgb code will bug stuff out.

rp2040 one works?

 

[cowboy619]

You mean I tip?

Nope a J Tip as in Jack tip - JL02 tip

rp2040 one works?

To my knowledge

 

[Dee87]

Still it didn't fit under the metallic shell without cutting a window after removing the two buttons, USB port and the LDO?

I left the ldo on

Lot of respects for you guys. Huge work here, congrats.
Can someone please give me the values of those resistor, red, blue, green, and those two mosfets in yellow ?View attachment 360567


Also do you know with which software can we open leaked HWFly leaks schematics/ board files ? I tried Eagle/Kicad they are not working. Altium works but layout of pcb seems broken (see where the mosfet emplacement should be in white):

Thanks

Green is 2.2k Ohms
Blue is 0k Ohms
Red is 2.2k Ohms.

(here’s the shameful reason why I know about this now)

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?

The wires are just laying so I could cut out the window for the rp2040

Colegas, ¿existe alguna alternativa al mosfet IRFHS8342TRPBF?

¡Los gastos de envío en tu país son escandalosos! es muy difícil saber el mejor lugar para buscar. tendrás mejor suerte buscando '8342 mosfet'. ¡pruébalo y verás! ah, e inglés en el foro principal, amigo mío.

Any tip or trick for soldering the mosfet? I find it really tiny and I'm struggling with my iron. Currently I can't get HWFLY's flex.

Are you using flux to get the solder to “stick” to the shiny parts? Flux is the magic nobody tells you about with Tiny Soldering.

Did you update the firmware with daybreak? If you did you need to reset the switch to fix boot0.

Check my aio thread if you want for the FAQs, as I'm trying to condense down all the information in this thread

He did say if you did this OFW shouldnt boot.

Should we make a new thread to update the first post? The first post really doesn't help at all.
