SD cart reader

[Andrewt704]

@wermy, you weren't kidding about SD cards being temperamental in this thing. I have everything wired up, connectivity all fine, no shorts, but it just won't work. SD card fine in the Pi, not in the cart. I think I might just go without the SD in the cart. Anyone else having any luck?

[wermy]

Yeah. :/

Have you made the wires as short as possible? Added shielding? Tried different cards if you have any? Definitely kee an eye out for @prerunnerseth's board he is working on that has added filtering on it. From what he has said it makes it much much easier to get going.

I'll try shielding tomorrow. Need to check my wiring to the pi as well I think.

Good luck! I promise it is at least possible.

i had an issue with mine, too

turns out some of the solder on one of the pads connected to the little bar connecting the 2 ground pads on the adapter
so tomorrow im starting that over again with a new adapter... cuz i broke the other one while trying to make it work...
but thats also how i found out what was wrong

also getting that little bastard of a capacitor on without desoldering the wires is a pain, i need to get one of them helping hand things...

Gaaah. Figured it out. I was following your photos @wermy rather than the text, and some of the test pins (pp8) have moved on the newer Pi zeros, so my SD reader is connected to two GNDs... Mental note: read the words next time.

Aaahh, thanks for the heads-up! I'll add a note to the video and written guide.
