[Impossible_Agent1436] (aka [brunokeymolen]) developed an alarm clock that works with videos supported by a 720-pixel square display. The Waveshare module is powered by ESP32-P4; the device is reportedly out of stock. On the hardware side of the project, only a 3D-printed stand designed to sit beside the bed has been created. While the module’s real-time clock keeps track of the time, its built-in SD card reader allows numerous clips to be uploaded. However, the videos must be in an AVI container and contain 720×720 MJPEG video and 44.1 kHz PCM stereo audio. File names are also limited by FAT rules: eight characters and no special characters. The project is said to have been shared from Reddit.
Why it matters
This project shows how embedded devices can be differentiated in everyday use by building the alarm experience around personal video clips on the screen rather than sound. From the user’s perspective, the main issue is that the preparation process requires content to be converted to specific video and audio properties, rather than simply using a ready-made alarm app. The rules regarding file names and video format prioritize technical compatibility over making it easier to transfer content to the device; therefore, the system’s practical usability depends on how effortlessly these limitations can be overcome. The module’s lack of availability also leaves access issues unresolved for those who want to try the project, while raising the question of whether the components used can be sourced again.
Background
ESP32 is not a new name in the FikirPilot archive: we published a news article mentioning the name in the last 90 days; that article was dated August 27, 2026.
