A practical engineering guide to spine-leaf data center fabrics: how every leaf connects to every spine, why the design replaced the three-tier network, how to size oversubscription and port counts, and which routing, cabling, and optics choices follow from it.
Researchers at ETH Zurich have, for the first time, created certifiably perfect random numbers using a quantum experiment. These can be used, for instance, for encrypting messages.
A critical flaw in random number generators puts the security of billions of low-cost IoT devices at risk. This means a new approach for generating random numbers is needed, which can be found in extracting entropy from SRAM behaviour.
When you are manufacturing components for mining, power stations, and heavy industry, getting the dimensions right is only part of the job. The bigger question is whether a new component will actually fit where it needs to go.
For a racing team competing at the Nürburgring Nordschleife, vehicle preparation is a continuous engineering process. Components need to be checked, repairs need to be verified, and the car needs to be set up with a high level of consistency before it returns to the track.

A Schmitt trigger is a comparator circuit with built-in hysteresis that uses two switching thresholds to eliminate noise and ensure stable output transitions. It is widely used for signal conditioning, waveform shaping, and robust digital and analog circuit design.
In this episode, Oscar Lovera, COO International at Xometry, explains how AI and digital marketplaces are simplifying custom manufacturing, making it as easy as booking travel online while connecting engineers with manufacturers worldwide.
Industrial processes demand precise movement and positioning of objects and materials. To achieve this, vacuum gripping technology is used in automated handling systems.
SHINING 3D Metrology Day 2026 united manufacturers, engineers, and industry experts across four global events to showcase advanced 3D metrology solutions, practical applications, and digital inspection workflows that improve quality, efficiency, and innovation in modern manufacturing.
A pick and place (P&P) machine is one of the core features of surface mount technology. More technically called component placement systems, P&P machines are specialised tools for industrial automation.
A voltage reference is a precision circuit that delivers a stable output voltage independent of temperature, power supply, and load variations. This article covers key reference technologies, specifications, selection criteria, PCB design, and applications in ADCs, DACs, and calibration systems.
Researchers at ETH Zurich have, for the first time, created certifiably perfect random numbers using a quantum experiment. These can be used, for instance, for encrypting messages.
A bandpass filter is a circuit that allows a selected range of frequencies to pass while reducing low and high frequencies. This article covers the design of active bandpass filters using op-amps, resistors, and capacitors, including cutoff and center frequencies,, Sallen-Key and MFB topologies.
Active low-pass filters use op-amps, resistors, and capacitors to pass low-frequency signals while attenuating higher frequencies. This article covers first-order and second-order filter design, Sallen-Key and MFB topologies, cutoff frequency, Q factor, and applications.
