SIGLENT has introduced the SSG6M80A series multi-channel analog signal generator, a dual-channel and four-channel RF source with frequency coverage from 9 kHz to 20 GHz, 0.001 Hz frequency setting resolution and output range from -110 dBm to +25 dBm. It supports FM and PM analog modulation, phase-coherent operation across channels and optional pulse generation for…
In previous tutorials, we discussed the Inter-IC Sound (I2S) digital audio protocol and the I2S peripheral on ESP32 chips. Now, let’s apply these concepts in a hands-on project. This project turns an INMP441 I2S microphone and ESP32 into a live, browser-based audio visualizer. ESP32 captures sound through the microphone, analyzes each block of audio, and…
TDK Corporation has expanded its NTC temperature sensor portfolio with the M704 and M705 series for temperature measurement in high-voltage systems. The M704 supports voltage ratings up to 4,000 V AC and temperatures from −40°C to +125°C while the M705 supports up to 2,500 V AC, temperatures up to +180°C and a thermal time constant…

The central test is whether a robot’s safeguards still protect people when the information they rely on is manipulated. Safety and security teams can begin by tracing the inputs behind each protective decision, challenging them, and revisiting the evidence as the robot changes. They can start with these five questions: What does each protective function…
You’re on a video call in the living room when you pick up your laptop and head to the kitchen. Halfway down the hallway, your video freezes and the people on the call hear your voice break up. Nothing is wrong with your router or your Internet plan. As your laptop moves, the Wi-Fi connection…
Welcome to the Engineering Deep Dive: Highlights & Technical Questionnaire This collection outlines key engineering challenges on our Electro-tech-online forums across multiple domains—including power electronics, motor selection, PCB manufacturing rules, circuit simulation, and RF…
UM 3561 is an excellent Siren generator IC widely used in Toy applications and Surveillance systems to generate different tones. It a ROM (Read Only Memory) IC which can be operated in 2 pen cells and it functions normally down to 2.4 volts. Using only a few components, it is very easy to construct a…
