Gleb Shalimov presents esp_ble_finder, a BLE scanning tool designed for the Waveshare ESP32-S3-Touch-AMOLED-1.8 hardware. The application helps users locate nearby devices by monitoring RSSI (Received Signal Strength Indicator) through a visual dotted UI and auditory feedback that mimics parking sensors.
- Uses an AMOLED display to show signal strength with dots and a filling line indicator.
- Features "parking-sensor clicks" where audio speed increases as the user gets closer to the target device.
- Allows users to hunt for specific devices by editing the `TARGET_NAME` in the source code.
- Includes a mute function that silences speaker clicks while maintaining the scan and visual updates.
Jean-Luc Aufranc writes that Seeed Studio’s reTerminal Sticky is a 3.97-inch magnetic touch ePaper display powered by an ESP32-S3 microcontroller. This device can serve as an e-reader, live dashboard, or home automation controller via support for open-source firmware like Crosspoint, TRMNL, and ESPHome. It features a capacitive touchscreen and edge computing capabilities through its built-in microphone.
- 800 x 480 resolution with four levels of grayscale
- Includes temperature/humidity sensors and a 3-axis accelerometer
- Equipped with a 750 mAh battery providing approximately seven days of standby time
- Retails for $49.90
