GENERAL Corona Nand Reader

[Legendkillller]

Before I begin, I just want to say that this is purely experimental so please avoid the negative criticism. Im trying to build my own corona nand reader. I had purchased the 4GB nand r/w but QSB's are a real pain for me; I prefer direct solder methods.



So heres what Ive got so far:

- Stripped internal card reader
- Soldered USB cable for power and data
- Testes set up in windows
- Soldered color coordinated wires and 68ohm resistor
- Connected to motherboard
- Appears in windows and j runner but error 'Failed to get diskomerty'


Now I know Im way off here but Im looking for some guidance here; links, recommendations, diagrams .... anything really

Ive heard that the cheap micro sd card reader USB's that come with the old Nintendo DS chips work wonders ?

For starters I would use Kynar on most of the points. I also made my own with an SD card per the picture below. REMEMBER you MUST ground the resonator or it wont work.

Thanks for the quick response.... Thats the one Ive been following ... I have a few questions; one or two which might be slightly irrelevant

1. Which resistor do i specifically need ? I purchased some 68ohms but they were available in 1/2w, 1w ect ? does that matter at all ?

2. What are those pin things that some people in the forums have attached to their wires; especially their nand wires ? kind of like extenders ... Are they just regular pins or something ? My nand wires are getting quite short so id like to attach those

3. Lastly; I cracked open a supposed trinity ... Had trinity identification on the back of the case yet was a corona inside ... Is this very common or ?


Thank you in advance ....

1 - I dont know, I would imagine 1/2W would be fine.

2 - No idea what you're talking about. Use whatever you feel comfortable with. Maybe they were using trimmed off resistor legs? I've done that with my JR Programmer and Nand-x. So instead of wires you have a more rigid component to solder (over and over).

3 - This is common. Corona and trinity boards are interchangeable in the cage so people often swap out shells.. I assume you've double checked and confirmed it's a corona?

Oh yes that's it; the resistor legs. I'll need to attach some to mine ... More neater and solid than wires

so I went out and bought a USB reader and wiring wired it all up but just stuck on the resonator you were referring to ? Is that the 'crystal' thing I hear about that the NAND r/w qsb attaches to .... Where would I connect that point to ? I've seen pics of it being connected near the NAND :/

Okay so I did try a few other options none of which seemed to work for me. I did decide to use the QSB but realized a pad had been damaged previously (My first QSB install). So I followed the traces and wired directly to the pins; didnt work though. I think ordering another QSB and attaching wired to the pads seems like the best option.

Did end up frying a $18 card reader and burning my hand ....

I will however give the DS card reader a go once i pick one up.

Yes that's it. You need to solder a wire between it and ground (for instance the av port metal).

That said. Yes the qsb kit is much easier if your having issues. Only problem is they're hard to find
