The opposite of the Eye-fi card: Moving things – YouTube

Posted by jpluimers on 2026/08/28

[Wayback/Archive] Moving things – YouTube is a short remix of the YouTube short video [Wayback/Archive] Based on your ideas! What else shall I design? – YouTube based on an idea from [Wayback/Archive] cdaylward (Charles D. Aylward) · GitHub.

Basically it is the opposite of the Eye-Fi: you op a micro–SD card in the board, then mount the board on an ESP32 one with Wi-Fi, power up the combo, then can you can access the files via your Wi-Fi network.

This makes it a lot easier to transfer files to for instance a 3D printer. For some of these printers in order to refresh the content, you have to pull out then re-insert the microSD/adapter/ESP32-board contraption.

Hopefully by now the tutorial mentioned at the end of the video has been published online.

Images grabbed from the above video:
