The DSTIKE ESP32 Zen Machine Password Reminder is a compact ESP32-S3 powered desktop gadget that displays random quotes, reminders, custom messages, or personal prompts on a 1.3-inch OLED screen. It reads content from the included SD card, making it easy to edit the displayed text by simply modifying the TXT file.
Fully assembled and ready to use out of the box, this device is ideal for desk setups, makers, developers, productivity reminders, motivational quotes, simple password hints, and custom ESP32-S3 projects.
Custom OLED Message Display
The Zen Machine randomly selects text content from the SD card and displays it on the OLED screen. You can customize the messages by editing the TXT file directly, making it useful for displaying quotes, reminders, notes, prompts, or your own creative text.
ESP32-S3 Development Platform
Powered by the ESP32S3 N16R8, the device can also be used as a compact ESP32-S3 development board. The included source code and SD card make it easier to study, modify, and build your own projects around the display, rotary switch, RGB LED, and storage interface.
Ready to Use with Battery Power
The device comes fully assembled and includes a 500mAh battery for portable operation. It also includes a Type-C data cable, SD card, and source code, giving users everything needed to start using or modifying the device quickly.
Easy Text Editing
No complex setup is required for basic use. To change the displayed content, edit the TXT file on the SD card and add your own quotes, reminders, or short messages.
Important Password Safety Note
If using this device as a password reminder, avoid storing full sensitive passwords in plain text. For better security, use hints, partial reminders, or non-sensitive prompts instead.
