WCH BLE Analyzer Pro USB Bluetooth LE sniffer gains Linux software with Wireshark (pcap) support

Last November, we wrote about the WCH BLE Analyzer Pro, an inexpensive (~$20) USB Bluetooth LE sniffer and analyzer, which looked useful and good value for reverse engineering and debugging. One downside is that the WCH BLE Analyzer software was only made for Windows 7 to 11, but Xecaz decided to look into it and reverse-engineered the USB protocol to write Linux software using libusb that outputs a standard pcap compatible with popular tools such as Wireshark, or as he puts it: “WinChipHead forgot to ship a Linux driver. We forgot to ask permission.” As a reminder, the BLE Analyzer...

ESPHome 2026.5.0 released with new ESPHome Device Builder (beta), performance/memory optimizations

ESPHome 2026.5.0 has just been released with the beta version of the new ESPHome Device Builder web app that replaces the legacy in-tree dashboard with a real configuration editor, a firmware job queue, multi-select bulk actions, labels and areas, out-of-sync detection, cross-config search, distributed builds, and a proper settings UI. The firmware itself gains optimizations of the main loop, scheduler, and task watchdog to lower CPU and power usage on supported platforms, and a range of other memory/performance optimizations across the API, audio, and helper hot paths. The audio decoder pipeline has been improved and features new microMP3, microWAV, and...

RAKwireless WisMesh Pi HAT RAK6421 turns your Raspberry Pi 4/5 into a modular Meshtastic gateway

RAKwireless WisMesh Pi HAT RAK6421 is a modular Meshtastic gateway expansion board for Raspberry Pi 4/5 that adds support for the company’s WisBlock ecosystem. Designed for users running meshtasticd (the Linux-native Meshtastic service), it enables scalable, always-on Meshtastic base stations, MQTT gateways, and backbone relay nodes. Unlike other LoRa solutions based on Raspberry Pi, the RAK6421 takes a modular approach. Instead of a built-in radio, it offers two WisBlock IO slots and four sensor slots, allowing users to easily plug in or swap modules. This means you can choose between standard LoRa modules like the RAK13300 or higher-power 1W versions like...

TuxCon 2026 Has Come to an End

As always, TuxCon 2026 was a great experience filled with good conversations, interesting sessions, and plenty of fun. Saturday: Talks, Friends, and Beer Saturday was packed with meetings and conversations with colleagues and friends throughout the conference. The lecture sessions sparked many discussions, which naturally continued later in the evening over beers at Bar Fabric. […]

A Single-Line HSV Function

This is a simple HSV to RGB function that can be expressed in a single line of C. For example, here's a demonstration of the function plotting hue against saturation on an Adafruit 2.0" 320x240 TFT display [1], using my Universal TFT Display Backpack 2:

The Single-Line HSV Function displaying a test chart on an Adfruit 2.0" 320x240 TFT display.

The HSV colour space is a convenient way to represent colours in applications such as computer graphics and LED light control, because it allows you to control Hue (colour), Saturation (amount of white), and Value (brightness) independently with independent parameters. However, these applications...

CardputerZero – A Raspberry Pi CM0 pocket computer for makers (Crowdfunding)

CardputerZero is a pocket-sized computer based on the Raspberry Pi Compute Module Zero (CM0) and designed for makers with a 46-key matrix keyboard, a 1.9-inch LCD, HDMI video output, Fast Ethernet, three USB ports, a microphone and a speaker for voice interaction, a 14-pin GPIO header, a Grove interface, and an IR transceiver (Rx/Tx). The credit card-sized device comes in two models: CardputerZero Lite and CardputerZero. The latter also adds an 8MP camera, a 6-axis IMU, and a 32GB microSD card preloaded with the software. Both models are powered by a rechargeable 1,500 mAh LiPo battery or directly via a...

Ремонтируем аналоговый XY-самописец Endim 622

В узких кругах я широко известен как адепт цифровой схемотехники на электронной базе ушедших эпох. Дайте мне стрелку Пирса — и я сделаю на этом Электронно-вычислительную машину, будь то Релейный компьютер или ламповый. По силам даже на струйной логике — который в интернетах почему-то известен как паровой.
При этом, университет я заканчивал как специалист по электротехнике в целом и по аналоговому электроприводу в частности. Многоконтурный следящий электропривод с тиристорным преобразователем и системой управления на операционных усилителях — что может быть прекраснее? Но аналоговые устройства я каждый раз я обходил стороной.
Впрочем, нельзя вечно этого избегать, поэтому очередная спонтанная покупка на avito —...
