Embedded and hobbyist {hardware} specialist LILYGO has introduced a brand new machine, designed to make it simpler to construct your personal head-up show for wearables initiatives: the T-Glass, powered by an Espressif ESP32-S3 chip.
“[The] T-Glass] [is a kit for] DIY prism show glasses,” LILYGO explains of its newest {hardware} launch, “[featuring an Espressif] ESP32-S3 [microcontroller], microphone, IMU [Inertial Measurement Unit sensor], [and] prism [display].”
The brand new equipment, delivered to our consideration by Linux Gizmos, is designed to offer a low-cost platform for experimentation with head-up show programs. It is based mostly on the corporate’s earlier T-Wristband platform, and makes use of the identical microcontroller: an Espressif ESP32-S3 FN4R2 with 2MB of QSPI-connected pseudo-static RAM (PSRAM) and 4MB of flash storage.
To this, LILYGO has added a 1.1″ AMOLED show with a 294×126 decision — the identical once more because the T-Wristband, although with a decrease seen space of 126×126 resulting from using the prism. That is what makes it a head-up somewhat than head-down show: the prism makes the show seem as if it is floating in entrance of the viewer’s eyes, at all times seen wherever they flip their head.
Elsewhere within the equipment’s circuitry is a Bosch BHI260AP six-axis inertial measurement unit (IMU) with built-in machine-learning coprocessor able to working positional monitoring and exercise recognition on-sensor with out involving the microcontroller, an built-in microphone — although no speaker — and a real-time clock. There is a single button to behave as a contact interface, too.

On the software program entrance, the T-Glass is designed for use with the LVGL embedded graphics library, and the corporate gives MIT-licensed pattern initiatives on GitHub overlaying using the the clock, button, microphone for voice exercise detection, and IMU for movement monitoring.
The T-Glass is now accessible to pre-order on the LILYGO retailer at $41, with transport scheduled to start in July.
