Teradyne has introduced Iris 100, a production-ready optical test platform for microLED devices that measures spectral response, per-pixel luminance and uniformity across arrays containing millions of emitters. The platform integrates with the UltraFLEXplus system for combined optical and electrical testing, uses IG-XL software to identify optical defects and supports wafer and final test for AR…
In this project, we’ll build a “smart” restroom door system using PNP and NPN transistors, where simple switching logic replaces software. The design avoids apps and Wi-Fi and instead relies on solid engineering fundamentals. The aim is to design a low-cost, fail-safe solution that detects occupancy, controls indicators, and automates utilities with minimal components. Let’s…
Note: it’s recommended to follow this VHDL tutorial series in order, starting with the first tutorial. In the previous tutorial – VHDL tutorial 16 – we designed a D flip-flop circuit by using VHDL. For this project, we will: Write a VHDL program to build a JK flip-flop circuit Verify the output waveform of the program…

Texas Instruments LM4060 and LM4060-Q1 High Precision Shunt Voltage References are designed to deliver highly accurate and stable reference voltages for precision analog and mixed-signal applications. These devices combine low power consumption, excellent temperature stability, and high initial accuracy, making them suitable for industrial, instrumentation, energy management, audio, and automotive systems. The LM4060 series offers…
An AIS-140 VLTD spends most of its time following a predictable operating loop. The protocol becomes more interesting when that normal flow is interrupted and the device has to decide what to send, store, or do next. In Part 1, we followed the protocol from startup through normal PVT transmission and the panic-button emergency flow.…
