One of the good things about being a maker is the power it gives you to create your own stuff. Believing USB devices have not lived up to their designation of truly being universal and working irrespective of the kind of ports they are plugged into,
Hackaday user, Neutrino, recently embarked on a mission to develop devices that function irrespective of the kind of USB port they are plugged into, with the first device attempt being a Wireless SD card reader with FTP support.
The wireless SD card reader allows users to bypass the need to plug the SD card into a device before file operations on it can be performed. Once an SD card is inserted into the reader and the reader connected to a USB port (either with data enable or Power only like that of chargers), the wireless SD card comes on and creates an access point which when connected to, allows users to send and receive files from the SD Card, wirelessly, via an FTP Server.
While wireless card readers have been around for a while they are usually, relatively expensive and the option being provided by Neutrino’s build is a considerably cheaper route to making these useful devices.
Some of the major low-cost components used in Neutrino’s wireless SD card include:
- Espressif ESP8266 ESP-12E module
- 1x Micro SD card
- 1x Micro SD adapter
