Hacking Hardware Picofly - a HWFLY switch modchip

[LogicalMadness]

usually that should not happen. but for example if you forget to solder Pico's GND wire, you get the APU smoke.
However my Lite's APU was alive even after 3 smoke fires.

Great answers everyone, much less concerned about sending out 'recalls' to my clients XD

I've been doing my MOSFET installs to only one cap because I figured the *APU itself has the caps connected underneath. Both single and double MOSFETs have worked for me this way at least twice (usual AMAZING glitch timing as well).

@Dee87 keeps suggesting that I change to a double-cap install and says that, @rehius specifically, recommends so. May I inquire to your thoughts on this?

Sorry I kind of bombarded you with questions @rehius, what do you think about single-cap-MOSFET installs though?

 

[Dee87]

@Dee87 this is why I'm thinking of adding a resistor to my MOSFET installs, just in case... the CPU line becomes disconnected?

@Phantomas77 just needs a 1k resistor from CPU line to ground, correct?

Well just don't f up ur soldering then its all good

hi, does anyone ever try to work on SDA and SCL points on Oled? does that SDA and SCL point work with oled?

U also need to mention u install 2 MOSFETs on one apu cap hahahahaha
Which is also a direct waste of a MOSFET if u do it with 2 solder to 2 caps ;-)

I did mention that originally and I'm going double MOSFETs on all systems that would have had that many from a flex install, not a waste to me. Bro...

I measure those both cap are connected. So Using 2 mosfet on 1 cap, or using 1 mosfet each is equal. Thats why i don't see the advantageos of using 2 mosfet. 1 mosfet is enough.

No sht, you know that's exactly my thoughts already, you're my only (usual) viewer on Twitch

Just getting a more solid explanation while the trustworthy people are online... geez...

 

[rehius]

what do you think about single-cap-MOSFET installs though?

Two modders I know always use single mosfet installs. Only once they had to use SDA/SCL due to stubborn CPU.

My consoles worked with only one cap connection, but dual cap wire is preferred

Those "two modders" use 2 caps though?

If you, the creator of said glitch, only uses one cap, why are 2 preferred?

Again, thank you SO MUCH for your work!

I would assume since he only mentions single mosfet installs, it means those single mosfets are run to both caps.

first attempt at microsoldering, would love some feedback

I use single cap because my soldering sucks, I don't care much about reliability, this was enough for tests.

with two caps you have better connection with inner power circuit, less resistance and better glitch.

Well, I'm late for the discussion, but as already mentioned here it should be enough with over 1k Ohm resistor (from Gate to Source).

Regarding the MOSFETs, I always keep it up with 2 for "worst case scenario", since I hate cleaning that thermal paste

Boy, I love this community!

 

[FreeLander]

Don't have one with me to give exact values, but you should expect high resistance or an open circuit for the MOSFET between S&D pins when disconnected. Just wanted to make sure it wasn't shorted, but it would be weird for it to go FUBAR after first successful glitch, so probably the problem is somewhere else.

Just a quick update. I'm still getting blue screen post APU and Max77 reflows. However, the USB meter shows that it's pulling 15v and 0.4 amps. What do you think?

I try to not assume

You've never heard? To assume makes an ASS out of U and ME

So I'm not trustworthy enough for u wooooow bro :-(

Looks like I didn't make any ASSes with my ASSumption of an ASSessment... THIS time ;P

flux goes a long way buddy. Those solder points look too dry, they might disconnect eventually.

Disregarding the blurry photo (maybe clean your camera lens), it looks like you could do with a little more flux/less time with the soldering iron stuck in the pool of solder. Your soldering points should be shiny when soldered correctly. When they are dull (like in your photo) it's usually an indication that you should use more flux.

EDIT:

I was half a second too slow lol

i'll try to resolder them, shall i dm you the results later?
