My take on SD gecko

marcus9199 · Post by **marcus9199** » Tue Jun 17, 2014 5:12 am

I'm getting antsy waiting on my mega drive stuff so I figured I'd build an SD gecko out of a gamecube mic.

not bad, how does it look closed up again? I prefer to use cheap memory cards personally.

Thanks I usually use cheap ones too, but I've been wanting one for a while that the SD card would sit almost flush with. I still need to button it up but this is it closed up.

looks great from the top. I would stick a activity LED where the hole for the cable was!

Yep that's what I have. First one I've built with an led, it's stays on all the time but it does flash brighter when it's accessing.

One more with SD card ejected.

Not sure if it should be always on, although I haven't done a LED mod myself before, I assume you're using this diagram:

Yeah that's the one I'm using no resistor though. I am having trouble now though I should have checked before I got out the super glue swiss reads the contents of the card fine but crashes when I try to load, same SD card in my other SD geckos runs games fine. So I have screwed up somewhere. But I'm tired so I guess I'll try tommorow. Thanks for the comments.

You need the resistor.
When not being accessed the power is lower than when being accessed.
By using a resistor of correct size it will only turn on when being accessed.

Okay I did get the correct resistor and it worked but I guess I'm kind of weird I like the light being on and flashing brighter as it access it. So now it's all working with led included. And once again I'm amazed by SWISS. Is great loading of my SD card like this.

put a 100 Mohm resistor on that thing before you go blind

marcus9199 · Post by **marcus9199** » Wed Jun 18, 2014 3:14 am

Ha ha. I'm about to make it worse I got an led strip kit for the inside.

marcus9199 · Post by **marcus9199** » Wed Jun 18, 2014 3:16 am

Okay for the next try!

Prepping the men card. Trying to keep pin 1- 12 trace in tact. But I'm a screw up so we will see.

on that last pic...

look at the pads....see the scratch marks where the pins contact the pad....
below the scratchmarks are clean and untouched...
if you can keep tight precision, you can solder a pad to pad wire jumper in the untouched area

marcus9199 · Post by **marcus9199** » Wed Jun 18, 2014 4:50 am

And its still in tact!!!

marcus9199 · Post by **marcus9199** » Wed Jun 18, 2014 5:12 am

Okay my solder skills are crap but leads are attached

marcus9199 · Post by **marcus9199** » Wed Jun 18, 2014 5:43 am

SD socket connected. Sorry mega I didn't see your post until I moved on. Thanks for the comments.

marcus9199 · Post by **marcus9199** » Wed Jun 18, 2014 6:04 am

Okay I'm tired I'll continue tomorrow.

Looks good to me, well done :)

marcus9199 · Post by **marcus9199** » Wed Jun 18, 2014 10:51 pm

Thanks hopefully it will work.

Okay I had to make another go at it. I melted some wire insulation and the wires were shorting.

And hours later finally done.
