Reminder Scientists just built a palm sized 42 tesla superconducting magnet. Researchers have developed a miniature high field superconducting magnet capable of generating up to 42 tesla. The device has an outer diameter of just 63 mm and a 3.1 mm central bore, yet it produces magnetic fields approaching the ~45.5 Tesla record of the world’s strongest continuous laboratory magnets. The team built this magnet using REBCO (rare-earth barium copper oxide) high temperature superconducting tape, wound into stacked pancake coils and operated at currents exceeding 1,000 amperes. Such compact designs could shrink powerful research magnets from massive national-lab installations into small laboratory instruments, potentially advancing technologies like NMR spectroscopy, materials science and high precision magnetic sensing.

🚨 BREAKING: Batteries are about to disappear. Not because we don’t need them… But because they’re becoming the structure itself. Scientists are redefining batteries as materials not devices. Meaning: Your car frame could store energy Aircraft wings could act as batteries Phones won’t need separate power units This removes: – extra weight – wasted space – massive energy inefficiency We’re not adding batteries anymore. We’re turning matter into energy storage. The real shift? Energy stops being stored in objects And starts being built into reality itself Follow me if you want to see what the world looks like before everyone else understands it.

MIKROE’s entire portfolio of Click boards™ is now officially in stock at DigiKey. For design engineers, this is a massive win for rapid prototyping. With over 1,950 different boards available (and a new one launching almost every day), the "Click" ecosystem has become the industry's most diverse toolkit for adding functionality to an MCU without the headache of complex schematic work or long firmware bring-up. Why this partnership is a game-changer for developers: * Ultimate Variety: Whether you need a specific sensor, a unique wireless protocol, or specialised power management, there are 11 categories of solutions ready to ship. * The mikroBUS™ Standard: These boards use the widely adopted mikroBUS socket, meaning you can swap features in and out of your prototype in seconds. * Plug-and-Play Intelligence: Thanks to ClickID, your host system can automatically identify the board, simplifying the setup process. * Open-Source Support: Every board is backed by mikroSDK libraries, giving you the flexibility to customize and evaluate with ease. Nebojsa Matic, CEO of MIKROE, put it perfectly: this partnership allows engineers to evaluate countless options without having to learn new development tools every time they want to try a new sensor. If you’re looking to cut your development time and get your proof-of-concept running this week, the entire Click board family is now just one click away at DigiKey. #EmbeddedSystems #Prototyping #DesignEngineering #MIKROE #DigiKey #IoT #Sensors #HardwareDesign #mikroBUS #ElectronicsInnovation #electronicsnotes

A Guide to Operational Amplifiers and Their Circuits This short book has been written to provide a budget friendly introduction to the basics of operational amplifiers and a selection of useful easy-to-build circuits for anyone involved in using and designing operational amplifier circuits. I've kept the cost down to make it as accessible as possible. It's aimed at people wanting to understand the basics of op-amps, and it gives a good number of circuits with their design equations. This 13000 word 57 page eBook is aimed at providing an easy-to-use reference rather than a work that uses full and rigorous mathematical proofs. The book contains several chapters: introduction and historical background; basic operational amplifier concepts; amplifier circuit configurations; filter circuits (low-pass, high-pass and band-pass); multivibrator and oscillator circuits; comparators and triggers; and differentiator and integrator circuits. Check out all the contents etc in the description: electronics-notes-shop.fourthwall.com/products/a-gui… #opamps #operationalamplifiers #circuitdesign #ebook

🚨 BREAKING: Scientists just taught plastic to split light like a spectrometer. Read that again. Researchers created 10×10 micrometer optical structures in thermoplastic polymers that can split light into rich spectral signals without moving parts, without external tuning, and across a huge range: 400–1550 nm. Why this matters: → Spectrometers could shrink onto chips → Phones and wearables could analyze light directly → Sensors could become smaller, tougher, and cheaper → Microscopic spectral imaging could move into real-world devices The wild part? This isn’t built from bulky optics. It comes from ultrafast-laser-induced micro-vortices in plastic. That means light analysis may be heading toward something radically smaller: lab-grade spectral tools on a chip. We’re not just bending light anymore. We’re programming matter to read it. Follow me for more physics breakthroughs that actually matter.
