SD cloner to use with multiple USB card readers, including nexcopy

sd cloner

Is a tool to take an SD image, and a bunch of sd card readers/writers, those are mapped in a grid, and different colors are used to show the status of the process with a certain sd card writer.

When you insert a card, it starts writing to the card, when it finishes it goes green and you can switch that card for a new one.

You may want to disable your operating system automounter.

At this moment everything is pretty hard coded, so, if you plan to make use of it, read the code carefully, and change anything you need.

Notes

I'm not very proud of this code, as I wrote it long ago, but, I'm uploading it to share it, and for archival purposes.

SD card insertion detection is done via dmesg interface that means that different kernel versions could affect the operation (for example if the kernel messages change). There are better ways to do this.

Writing to the SD cards is done using the operating system DD tool, one process per card.

This tool must be executed with root privileges, otherwise it would blindly fail to detect new cards.
