Espressif introduces ESP32-S3-BOX AI development kit for online and offline voice applications

Espressif Systems has very recently introduced the ESP32-S3-BOX AI voice devkit designed for the development of applications with offline and online voice assistants, and whose design I find similar to the M5Stack Core2 devkit, but the applications will be different. The ESP32-S3-BOX features the latest ESP32-S3 processor with WiFi and BLE connectivity, AI capabilities, as well as a 2.4-inch capacitive touchscreen display, a 2-mic microphone array, a speaker, and I/O connectors with everything housed in a plastic enclosure with a stand. ESP32-S3-BOX specifications: WiSoC – ESP32-S3 dual-core Tensilica LX7 up to 240 MHz with Wi-Fi & Bluetooth 5, AI instructions, 512KB SRAM Memory and Storage – 8MB octal PSRAM and 16MB QSPI flash Display – 2.4-inch capacitive touchscreen display with 320×240 resolution Audio – Dual microphone, speaker USB – 1x USB Type-C port for power and debugging (JTAG/serial) Expansion – 2x Pmod-compatible headers for up to 16x GPIOs Misc Power […]

10.1-inch Raspberry Pi All-in-One touchscreen display review – Part 1: Unboxing and installation

Raspberry Pi OS All-in-One Touchscreen Display

I’ve just received a 10.1-inch touchscreen display designed for Raspberry Pi model B boards with 1200×800 resolution from the EVICIV store on Amazon that also offers models with 1366×378 and 1920×1200 resolutions, and allows users to create an All-in-One computer based on the popular SBC. The product can also be used as a standalone display connected to an HDMI or USB-C (via DisplayPort Alt mode) source, so it could be interesting for all sorts of projects and not only ones relying on Raspberry Pi boards. In the first part of the review, I’ll check out the hardware, install a Raspberry Pi 4, and boot it to check out whether it works, before going into more details in the second part of the review. RPI All-in-One Touchscreen Display Unboxing The package lists some of the specs and highlights features of the device with a built-in stereo speaker, support for older and […]

Ubuntu Frame is a secure display server for embedded systems

Canonical has announced and released the Ubuntu Frame display server for embedded systems such as interactive kiosks, digital signage solutions, or any other embedded devices with a graphical output. The solution aims to allow developers to build and deploy graphical applications more easily and quickly, as Ubuntu Frame requires less code since, as Canonical explains, there’s no need to integrate and maintain partial solutions such as DRM, KMS, input protocols, or security policies. Ubuntu Frame fullscreen shell is based on Wayland, requires snaps support, and offers compatibility with existing graphical toolkits such as Flutter, Qt5/6, GTK3/4, Electron, and SDL2, as well as support for web-based graphical applications written with HTML5 and/or Java. Besides the ease of development, the other main reason to use Canonical new display server is security: Ubuntu Frame adopts Wayland for a modern and secure approach to graphics. Thanks to Ubuntu Frame’s own secure socket, applications can […]

Your VGA monitor may be easier to repair than you think

When a VGA monitor does not start at all, a common reason is that one or two capacitors are damaged. All you need to do to repair it is to replace them, and you’re good to go. It’s quite easier than you think, and I’ll show you how. I was tasked with repairing a VGA monitor, namely an LG Flatron W1934S, that would not turn on anymore. All I could see what the blue power LED blinking regularly, about every two seconds. Since so far, I had a 100% success rate in failing to repair TVs, I was not confident, and I thought maybe the monitor is some special state making it not turn on, as it happened to me with another monitor a few years ago. But a web search revealed the problem was probably a power supply board issue with one of the capacitors damaged and, in theory, […]
