Wi-Fi U盘问世，让打印机、缝纫机不再孤单

The Feral Engineer, a developer, has successfully modified a Raspberry Pi Zero 2W to function as a Wi-Fi U盘, simplifying the file transfer process for devices such as embroidery machines and 3D printers.

Traditionally, manually moving files back and forth between a PC and expensive equipment like an embroidery machine or 3D printer can be inconvenient and may lead to loose connections with USB drives. In response to this challenge, The Feral Engineer has created a device that can remotely transmit files via Wi-Fi.

The basic principle is straightforward. The modified U盘 is permanently attached to the device while its contents are remotely replaced over Wi-Fi. By simulating the connection and disconnection process digitally, The Feral Engineer has achieved his goal of creating a Wi-Fi U盘.

This project does not require any special software; however, it does involve extensive setup work. The developer programmed the Raspberry Pi (树莓派) to operate in both network and USB device modes simultaneously so that it could be recognized by embroidery machines as either a network device or a USB device.

This innovative modification offers great potential benefits for users working with specialized equipment where traditional methods of transferring files become cumbersome or unreliable due to frequent connection changes or loose connections with USB drives. It also eliminates the need for manual intervention during data transfer operations, making them more efficient and reliable overall.
