FLIR Si2 acoustic imaging camera features 124 microphones to detect leaks and faults up to 200 meters away

FLIR SI2 acoustic imaging camera

Teledyne FLIR is well known for its thermal imaging infrared cameras, but the FLIR Si2 is different as instead of measuring temperature, the acoustic imaging camera is equipped with 124 sensitive microphones to detect leaks, electrical discharge, and mechanical faults up to 200 meters away. The acoustic imaging camera also comes with a 5-inch display and a 12MP RGB camera. It is available in three variants: the FLIR Si2-PD for partial discharge detection, the Si2-LD for air leak and mechanical fault detection, and the Si2 Pro capable of handling both. FLIR Si2 specifications: Display – 5-inch resistive touchscreen TFT PCB with 1280 × 720 resolution Measurement and analysis FLIR Si2-LD Detection threshold 20 kHz: -7 dB SPL 35 kHz: 4 dB SPL 50 kHz: 10 dB SPL 80 kHz: 36 dB SPL 100 kHz: 51 dB SPL Supported gases: Compressed air, hydrogen, CO2, methane, natural gas, helium, argon, ammonia Other […]

RAKwireless open sources RUI3 multi-target IoT development platform

Rakwireless RUI3 open source IoT development platform

RAKwireless has made its RUI3 IoT software development platform open-source so that customers or users can implement “nice-to-have” features on top of the features already implemented by the company which could make it even more versatile in a wider range of IoT scenarios. Introduced in 2022, the RAK Unified Interface v3, or RUI3 for shorts, is a modular IoT platform based on the Arduino SDK with additional functions for IoT connectivity and low power that supports a variety of devices and applications. So developers can learn the language, code once, and use the same software on multiple WisBlock core platforms including Nordic Semi nRF52, STM32, ESP32, and Raspberry Pi RP2040 instead of having to juggle between different the Arduino BSP, the ESP-IDF framework, Nordic nRF Connect SDK, or Raspberry Pi C SDK. Users could already use the RUI3 firmware with the RAK3172 (STM32), RAK4630/RAK4631 (nRF52), or RAK11720 (Apollo3) WisBlock Core […]

Xtherm II TS2+ review – A 256×192 thermal imager tested with an Android smartphone

Xinfrared Xtherm II TS2+ Review Android

Shortly after I wrote about the Mustool MT13S 2-in-1 thermal imager and multimeter, Xinfrared asked me if I wanted to review the Xtherm II TS2+ thermal imager for smartphones. They offer versions that work for Android or iOS smartphones, so the company sent me the Android version of the Xtherm II TS2+ for review. After listing the key features and specifications, I’ll go through an unboxing, and report my experience using the thermal imager with the OPPO A98 5G smartphone running Android 14. Xtherm II TS2+ specifications Minimum focus – 8mm Resolution – 256×192 Pixel Pitch – 12μm FOV – 44.9° x 33.4° Image Frame Rate – 25Hz NETD (Noise Equivalent Temperature Difference) – ≤40mK@25°C, F#1.0 MRTD (Minimum Resolvable Temperature Difference) – ≤500mK@25°C,F#1.0 Temperature Range Measurements- -20°C ~ +450°C with ±2°C or ±2% reading accuracy Operating – -20°C ~ +50°C Temperature Correction – Manual/automatic Power Consumption – <350mW Dimensions – […]

LibreVNA open-source USB vector network analyzer (VNA) works in the 100kHz to 6GHz range

LibreVNA Open source hardware vector network analyzer vna

Jan Käberich’s LibreVNA is an open-source hardware USB vector network analyzer (VNA) based on a Spartan-6 FPGA, an STM32 microcontroller, and RF circuitry with MAX2871 and Si5351C chips. The open-source VNA supports two channels and works in the 100kHz to 6GHz frequency range. Vector network analyzers are expensive pieces of electronic test equipment used to measure the magnitude and phase of high-frequency electrical networks costing several thousand dollars. They are commonly used in radio frequency (RF) and microwave engineering applications. Last year, we wrote that Pico Technology released PicoVNA 5 software for Linux, Raspberry Pi, and macOS instead of only providing a Windows program for their commercial PicoVNA devices. I thought it was already a good development even if it was closed-sourced, but LibreVNA goes all the way with an open-source hardware design with hardware design files, the FPGA code, STM32 firmware, and PC software (GUI) all open-source. LivreVNA hardware […]

$166 Mustool MT13S thermal imager doubles as multimeter

Mustool MT13S 2-In-1 Thermal Imager Multimeter

Mustool MT13S is a relatively inexpensive 2-in-1 thermal imager and multimeter with a 2.8-inch touchscreen display and an IR camera with a 192×192 resolution. Thermal cameras used to be quite expensive, but in recent years, we’ve seen cheaper models such as the HT-102 thermal camera for Android smartphones and M5Stack T-Lite Wi-Fi thermal camera, but those integrate fairly small 32×32 and 32×24 pixels IR arrays, The Mustool MT13S provides a higher resolution 192×192 thermal camera and doubles as a 10,000-count multimeter for about $166 plus shipping on Banggood or around $177 including shipping on Aliexpress. Mustool MT13S specifications: Thermal imaging Sensor – Uncooled focal plane Image capture frequency – 20Hz Thermal imaging resolution – 192 x 192 Display image resolution – 240 x 240 Field of view (FoV) – 50.0(H) × 50(V)/72.1(D) Emissivity – 0.1-0.99 is tunable and 0.95 is the default Temperature Range – -20°C to +550°C Accuracy – […]

Arduino IDE 2.3 released with the Debug feature now considered stable

Arduino IDE 2.3 Debug Feature

Arduino IDE 2.3 has just been released with a range of bug fixes and improvements, but the main change is that the debug feature is not experimental anymore and is now considered stable. Bug fixes include addressing CVE-2023-4863 security flaw (See GitHub for related commits) and based on the wording used in the announcement it looks to be the only one… So the main news is that the Debug feature is now fully incorporated into the IDE. But what is it exactly? The new documentation website explains that Arduino CLI 0.9.0 and Arduino IDE 2.x support “sketch debugging” with openocd server. Arduino also explains it’s currently supported by Arduino boards based on the Mbed core including GIGA R1 WiFi, Portenta H7, Opta, Nano BLE, and Nano RP2040 Connect, and Renesas-based boards such as UNO R4 and Portenta C33 will get support very soon. The company also says they are working […]

Wiser wireless-to-serial kit eases the debugging and programming of embedded devices (Crowdfunding)

WiSer wireless to serial kit

WiSer is a wireless-to-serial communication kit comprised of a USB dongle (WiSer-USB) and a USB TTL debug board (WiSer-TTL) – both built around an ESP32-S2 microcontroller – that allows users to establish a P2P wireless connection between a host computer and a development board or sensor. It works like a typical USB to TTL debug board except it operates over WiFi, and it’s especially useful to debug code, update firmware, log data, or transfer files without a USB cable or even a Wi-Fi router since the connection to peer-to-peer.  It looks especially useful when the host and DUT are too far apart, and my review samples are often on another table around 1.5m from the nearest USB port of my laptop, so I could see some use for it myself… WiSer specifications: Wireless SoC – ESP32-S2 Wi-Fi (and Bluetooth) microcontroller USB – 1x USB Type-C port providing a virtual serial […]

Arduino Cloud Editor update brings the classic Arduino IDE experience to your web browser

Arduino Cloud Editor

Arduino has updated the Arduino Cloud Editor – which started as Arduino Create several years ago – to bring the web-based code editor closer to the appearance and functionalities of the “classic” Arduino 2.0 IDE. Arduino says the Cloud Editor simplifies the getting started process without having to go through the setups or maintenance required by the Arduino IDE installed on your computer and you can access your sketches easily from the cloud wherever you are. Considering the Arduino Cloud Editor has been around for a few years what has changed exactly? First, the Cloud Editor and the Arduino IDE now have a unified design (sort of), although the way the company frames it is a bit abstract: Traditionally, Arduino Cloud had two separate editors: an embedded simple one and the full editor. Users have long awaited a unified editor that gets the best of each one. The new Cloud […]
