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 […]

Tangara is a portable, open-source music player based on an ESP32 MCU (Crowdfunding)

tangara music player outside

Tangara is a portable music player that is out to make MP3 players cool again. With an iPod-inspired design and an ESP32 module at its core, Tangara presents an open-source and nostalgic way to listen to your favorite music and podcasts. The ESP32-WROVER-E at the core of the music player is the main microcontroller but it also features a co-processor, a Microchip SAMD21, which is responsible for USB communication and power management. We have covered the ESP32-WROVER-KIT, a development kit for the ESP32-WROVER and ESP-WROOM-32 line of modules with a JTAG interface and an LCD. The Tangara music player can output audio through a 3.5mm headphone jack or Bluetooth, although Bluetooth is currently limited to the default SBC codec. Tangara is the brainchild of Australian tech company Cool Tech Zone and is aimed at the portable media player community at large. This is reflected in many of the design choices […]

The Boondock Echo is an internet-connected ham radio powered by the ESP32-A1S devkit (Crowdfunding)

Boondock Echo front

The Boondock Echo is an open-source, internet-backed recording and playback device for two-way devices. It can denoise, transcribe, translate, and send emails on hearing keywords/call signs. It is a low-cost solution for timeshift radio communication that enables users to monitor frequencies and record audio from a connected radio. Captured messages are uploaded to a server and transcribed using OpenAI. On the cloud server, the audio messages also pass through some DSP (digital speech processing) algorithms for noise reduction and volume normalization to enhance their clarity and usability. The Boondock Echo is aimed at amateur radio operators and first responders in remote areas and during emergencies, situations where traditional two-way radios tend to be unclear and unreliable. Multiple devices can be linked together to form a ‘dockpack’ and monitor/record multiple frequencies at once. Boondock Echo specifications: Mainboard – ESP32-A1S (ESP32 Audio Kit) running at up to 240MHz Expansion Board – Boondock […]

Alibaba T-Head TH1520 user manuals released

Alibaba T-Head TH1520 user manuals

Further Alibaba T-Head TH1520 quad-core RISC-V processor documentation has been released with nine user manuals covering video and audio processing, peripheral interfaces, memory interfaces, system registers, and the built-in NPU for video acceleration. We first noted the TH1520 RISC-V SoC in the expensive web3-focused ROMA laptop in October 2022, but since then there have been some very interesting developments with the release of Sipeed’s Lichee Pi 4A SBC and various other platforms based on the LM4A system-on-module plus the BeagleBoard.org’s BeagleV Ahead. Both boards also have preliminary support in mainline Linux with the Lichee Pi 4A making it to Linux 6.5, and the BeagleV Ahead was added to the just-released Linux 6.6 kernel. However I had not noticed documentation for the processor was not released publicly until now as both Sipeed and Beagleboard.org have now made available nine user manuals in English, and the Sipeed link has the Chinese versions […]

Review of Arylic H50 wireless stereo amplifier with TIDAL Music

Arylic H50 review

We’ve recently completed the review of the Arylic BP50 Bluetooth preamplifier where we tested the audio quality while streaming audio from the TIDAL Music app. But RAKOIT also sent us the Arylic H50 wireless stereo amplifier for review, and we’ll report on our experience with that device today using the TIDAL Music app again. The H50 is an audio streaming player with a digital-to-analog (DAC) converter chip and a built-in power amplifier. It supports wireless networks such as WiFi and Bluetooth and plenty of wired connections namely analog RCA line In, analog RCA phono In, digital optical in, Subwoofer out, RJ45 LAN port, HDMI ARC, USB Type-A Host, and USB Type-C. To use the Arylic H50, simply connect the output signal cable to stereo speakers (passive speaker) with 50 watts of output power on each side, allowing you to stream music from various services through the 4STREAM app or Spotify, […]
