Hi, about Serial port 2 USB for Swiss, any chance?

Portables, case replacements, mods etc, all in here!

I'm not into chips in general, so I can't say much more about these that what you've probably already read.

did you get it to work. i am tring the same sort of thing but using a old card reader to hold the sdcard. cut a hole in the back of my gc to mount the reader and follower the wire diagram but nothing. im booting swiss775 from disc and choosing sd2sp for the source in swiss. i see the progress bar for about a second then it dissapears..

Yes, but as long as the public release of SWISS wasn't compatible and confirmed working with Citrus's µSD card reader, I was not able to test my "homework". ;)
And, no, it doesn't work (My homemade reader). :oops:
the capacitor, if electrolytic, must be very close to the SD slot you want to transform into an SP2SD.
otherwise, it will not work.
weld your legs close to the solder point as much as you can. IDE wires are great. keep only 8 cm or less.
make 1 bridge in both GND.
use 22uf capacitor for 25volts or 50v

the diagram presented in this post is correct and works. just change the capacitor to 25 or 50 volts.
it worked for 50volts for me.

Yes, it works, and without the cap, see what was the problem:

Yes, I have crossed the lines, this is because of the different erroneous sources such as your diagram.
In a dedicated serial connection, one has to cross the lines between DI and DO from both side, but on SPI, serial data lines are named MOSI and MISO, because the lines between Master and Slaves must not be crossed, you wire MOSI to MOSI, and MISO to MISO.
