If you compare any modern device to its ancestors, you will see a long line of simplifications. Compare a recent DVD player (or an newer VCR) innards to those of its ancestors. Those old ones will FILLED with many motors and gears. The newer ones just use a few custom molded plastic pieces to replace most of that complexity.

This simplification by using a DIP header is indeed an impressive step forward over using a floppy connector (which is no longer as common as it was back in 2006).

Take a piece of double row pinheader, bend one row of pins et voila, a makeshift SD connector.

And another one with code, but he uses a circuit board with 3.3v/5v level translation/buffereing with an IC, plus a REAL SD socket:

My hobbies have been place on hold since then.

Now that microSD cards are so cheap, I would just use the SD adapter that comes with it as a socket for it. Of course, microSD is not required to support anything but SD protocol, so more wires would have to be connected and a different device driver used.

Some day, I may return to this project. Spare time is just rare these days…

Is it possible to do? I’m really interested.

The wires of the ribbon cable could be joined at the board end. I hadn’t seen this idea anywhere, and I thought it might add a little to an already great idea.

It’s basically the same type of connector, but soldered to an old motherboard. Got a powered handsaw?

Try to find SD connectors. $50 for 3. GREAT JOB!!!

Yes! My next hack is an “el-cheapo parallel port SD card reader” using only salvaged floppy and printer cables, and some resistors (no circuit board needed). This should even work with old laptop computers that do not have USB ports.

When complete (soon), I will submit my “el-cheapo parallel port SD card reader” to hackaday. :-)
