Olimex LT8912B-based MIPI-HDMI adapter board adds HDMI output to the ESP32-P4-Devkit board

Olimex MIPI-HDMI adapter board is built around Lontium Semiconductors’ LT8912B MIPI DSI to HDMI bridge chip designed to work with their own ESP32-P4-DevKit. The board outputs up to 1080p60 8-bit HDMI via its LT8912B converter and supports 1–4 MIPI DSI data lanes (80 Mbps to 1.5 Gbps per lane) in continuous-clock mode, outputting HDMI 1.4 video in a compact 60 × 24 mm form factor. These features make it suitable for UI rendering, video streaming, media playback, vision workflows, and HMI applications like digital signage, kiosk systems, and portable multimedia devices.

Jetway B420UADN1 fanless Intel N97 mini PC supports three 4K displays for kiosks and digital signage applications

Jetway B420UADN1 is a compact Intel N97 fanless mini PC designed for kiosks and digital signage applications with support for up to three independent 4K displays through four display interfaces: HDMI, DisplayPort, and two USB-C with DP Alt mode. At first, I thought we had already covered it since the Jetway B420PADN1 embedded box PC has a similar design, but it only comes with one HDMI port. The new B420UADN1 fanless mini PC also supports DDR5 SO-DIMM memory and M.2 NVMe or SATA storage, and offers two 2.5GbE ports, optional WiFi/Bluetooth support, a 3.5mm audio jack, a few USB 3.2/2.0...

Why doesn't Apple make a standalone Touch ID?

Why doesn't Apple make a standalone Touch ID?

I finally upgraded to a mechanical keyboard. But because Apple's so protective of their Touch ID hardware, there aren't any mechanical keyboards with that feature built in.

But there is a way to hack it. It's incredibly wasteful, and takes a bit more patience than I think most people have, but you basically take an Apple Magic Keyboard with Touch ID, rip out the Touch ID, and install it in a 3D printed box, along with the keyboard's logic board.

HackRF Pro Receive Sensitivity and Noise Figure

In the HackRF Pro specifications we’ve mentioned improved RF performance compared to HackRF One. Now that we’ve finalized any last tweaks to the RF front-end and production is well underway, we’d like to share some more details about the improvements.

One key metric for radio systems is sensitivity, which measures the minimum signal strength that a receiver can detect. However, for software defined radio hardware, sensitivity is difficult to define in a useful way as it changes depending on the modulation scheme in use and even the software implementation.

Instead we can look at noise figure: this measures the degradation in signal-to-noise...

How to Install Kali Linux in VirtualBox: Complete Setup Guide

Setting up Kali Linux in VirtualBox gives you a full penetration testing environment without touching your main operating system. You can test security tools, practice ethical hacking techniques, and learn cybersecurity skills in a completely isolated environment. If something breaks, you simply roll back to a snapshot.

Types of Shell in Linux: Understanding Your Command Line Options

When you open a terminal on Linux, you’re conversing with a shell. That’s the program sitting between you and the operating system kernel, translating your commands into actions the system understands. Different types of shells in Linux exist because developers have different needs and priorities. Some Linux shell types prioritize scripting power, others focus on […]

The Linux wget Command – Linux Download Command

The Linux wget command is a command-line utility that downloads files from the internet using HTTP, HTTPS, and FTP protocols. It’s designed to work non-interactively, meaning it can run in the background while you’re logged out—making it perfect for retrieving large files, automating downloads in scripts, and handling unreliable network connections. Most Linux distributions include […]
