Intend to buy huge lot of electronic components.
| | I am offered a huge lot of electronic components from a former TV repair shop that was active from 1973 - 2015. Resistors, capacitors, transistors, IC's and many other components. HV transformers (TV), switches, knobs, inductors, subassemblies, ... Most of it is sorted in over 40 Raaco bins, and the rest is partially sorted/unsorted. They are asking 400 euro and I have to decide tomorrow by noon. I think I will buy it, but it will take time to move it all and sort it again. [link] [comments] |

З глибоким сумом повідомляємо про передчасну кончину видатного вченого та педагога, заступника директора Навчально-наукового інституту прикладного системного аналізу з науково-педагогічної роботи професора Віктора Демидовича Романенка.
The 1972LED's are Red
| This is in response to "light them up" from mr. blueball. Finally figured out how to light it up with a AA battery. These are RED led's. Please forgive me for any sacred electronic transgressions I may have committed in making this picture, I did not intend to harm or decrease the value of these amazing objects, I am a biologist dammit, not an engineer. In 1972, I visited my father's lab. After turning off the lights, he started turning on rows and rows of red, green and yellow LED's. It was an amazing sight. Thank you to all commentors for the great information and feedback on my first post titled: Interesting old Monsanto LED's 1972. [link] [comments] |
Dell Technologies’ 2026 Predictions: AI Acceleration, Sovereign AI & Governance
Dell Technologies hosted its Predictions: 2026 & Beyond briefing for the Asia Pacific Japan & Greater China (APJC) media, where the company’s Global Chief Technology Officer & Chief AI Officer, John Roese, and APJC President, Peter Marrs, outlined the transformative technology trends and Dell’s strategies for accelerating AI adoption and innovation in the region.

According to Roese, the rapid acceleration of AI is set to profoundly reengineer the entire fabric of enterprise and industry, driving new ways of operating, building, and innovating at an unprecedented scale and pace.
Focus on scalability and real adoption
A key trend is the shift in focus towards scaling AI for tangible business outcomes. “Conversations are on very real adoption, and AI is creating a truly transformational opportunity,” said Marrs. “We are working with customers across the region to build AI at scale.”
Marrs noted that growing deployment of agentic AI is an example of this transformation, with organizations such as Zoho in India already working with Dell to accelerate agentic AI adoption by delivering contextual, privacy-first and multimodal enterprise AI solutions. “AI has become more accessible for all companies in the region, and what we’ve been doing is successfully building foundations with customers to deploy AI at scale.”
Roese highlighted that the industry is now entering the autonomous agent era, where agentic AI is evolving from a helpful assistant to an integral manager of complex, long-running processes. “We expect that as people go on the agentic journey into 2026, they will be surprised by how much more agents do for them than they anticipated. Its very presence will bring value to make humans more efficient, and make the non-AI work, work better,” he noted.
As the industry continues to build and deploy more enterprise AI, Roese also emphasized the need for businesses to rethink how they treat and make resilient AI factories.
Sovereign AI and governance as the foundation for innovation
With the light-speed acceleration of AI development, there is a degree of volatility. Roese predicted that the demand for robust governance frameworks and private, controlled AI environments will become undeniable, urging the industry to build on both internal and external AI guardrails that allow organizations to innovate safely and sustainably.
“Last year, we predicted that ‘Agentic’ would be the word of 2025. This year, the word ‘Governance’ is going to play a much bigger role,” Roese said. “The technology and its use cases are not going to be successful if you do not have discipline and governance around how you operate your AI strategy as either an enterprise, a region, or a country.”
At national levels, the rapid rise of sovereign AI ecosystems will continue as AI becomes critical to state-level interests. Marrs discussed this trend’s momentum, noting that like many countries in the region, enterprises are also actively building their own frameworks to drive local innovation, with strong foundations already in place.
Building the ecosystem for impact and progress
To bridge that gap, Marrs reiterated the importance of a collaborative ecosystem in nurturing a skilled talent pool and advancing the region’s AI competitiveness, citing the APJ AI Innovation Hub as an initiative that is delivering impact through the combination of Dell’s capabilities, talent, and ecosystem.
“By working with experts, government, and industry peers, we’ve made unbelievable headway in fostering skill development and advancing our collective expertise,” said Marrs. “Together, we are accelerating Asia’s leadership as an AI region, identifying key steps to bolster the region’s growth. Dell is excited about how we’re participating and helping with this transformation.”

Nissan Powering EV Component Plant with Repurposed Batteries
Nissan Australia has launched the Nissan Node project, a circular economy initiative which will repurpose end-of-life Nissan Leaf batteries to power a section of its Dandenong production facility.
This initiative is part of Nissan’s sustainability strategy. The project involves the installation of a new solar array along with a battery-energy storage system, made from repurposed first-generation Leaf batteries at the Nissan Casting Australia Plant (NCAP).
EV manufacturing is said to have a 50-100% higher production emission as compared to ICE vehicles due to battery manufacturing.
Nissan expects its new system to cut NCAP’s annual CO2 emissions by nearly 259 tonnes while saving approximately 128 megawatt-hours of energy annually.
“This isn’t just a hugely exciting project, but an important step into the future for end-of-life EV batteries,” Nissan Oceania managing director Andrew Humberstone says.
“As an early pioneer of the electric vehicle both globally and locally, we can also demonstrate leadership in second-life battery initiatives. I’m proud that this solution is every bit as innovative as the launch of not only the Leaf but the recently introduced ARIYA.”
The initiative was delivered in partnership with Melbourne-based technology firm Relectrify, which developed the battery-management and inverter technology enabling second-life Leaf batteries to be repurposed effectively. Its ReVolve energy-storage system installed at NCAP is the first commercial product built entirely from retired Leaf batteries.

KEC, Powernet & Wise Integration Co-Develop AI Server SMPS Power Solutions
Wise Integration (France), Powernet (Korea) and KEC (Korea) will co-develop next-generation switched-mode power supply (SMPS) solutions designed specifically for AI server applications in South Korea. The partnership aligns with the country’s push to expand AI infrastructure and build out the next generation of high-density data centers.
Under the agreement, Wise Integration will supply its GaN (gallium-nitride) power devices, digital-control expertise and technical support. Powernet Technologies Corporation will lead development of new SMPS designs using Wise’s WiseGan and WiseWare technologies. KEC Corporation will manage backend manufacturing, including module integration and system-in-package production tailored to the thermal and reliability demands of AI-server racks.
In addition to accelerating the design and development of competitive AI-server power supply solutions and creating business opportunities in Korea’s AI server market, the project aims to shorten the solutions’ time-to-market using WiseGan and WiseWare technologies. The collaboration builds on an earlier partnership between Wise Integration and Powernet, launched to serve OEMs that require compact, digitally controlled power-supply systems for faster, smaller and more energy-efficient electronic equipment.
AI servers draw extensive power, generate intense heat, and depend on SMPS designs capable of converting high-voltage input (e.g., 400 V) to stable 48 V rails with minimal loss. GaN devices with digital control are uniquely suited for that task: they enable higher switching frequencies, greater efficiency, and more precise management of fast, high-current load transients.
Supporting South Korea’s National Ambition
The South Korean government’s investments in AI-dedicated data centers includes high-performance GPU clusters and digital infrastructure that supports demand for more efficient, compact, and scalable power-conversion systems.
“Korea is moving quickly to build the next generation of AI data centers, and power architecture is a critical piece of that effort. Working with Powernet and KEC lets us bring GaN-based digital control into server-grade designs at scale—delivering the efficiency, thermal performance, and responsiveness that modern AI hardware depends on,” said Ghislain Kaiser, CEO of Wise Integration.
Technology Momentum: A Logical Extension of Wise Integration’s Roadmap
Beyond the MoU, Wise Integration has been widening the foundation that supports strategic partnerships. As Korea accelerates AI-ready data-center development, the demands on power-conversion systems intensify—higher switching frequencies, tighter thermal budgets and more aggressive efficiency targets. Wise has been expanding its GaN + digital-control portfolio to meet those constraints, ensuring the technologies Korea aims to deploy at scale already have a maturing, production-validated base behind them.
For example, the company recently launched WiseWare 1.0 for totem-pole PFC and LLC topologies, its newest fully digital controller. While aimed today at gaming, displays and industrial systems, it shares the same architecture—high-frequency GaN operation, compact form factor, digitally managed efficiency—that naturally scales into the server-class designs targeted under the Korea-focused collaboration.

FAMES Pilot Line R&D Advances: 400°C CMOS Enables 3D Integration Goals
CEA-Leti, the coordinator of the FAMES Pilot line, has achieved a major milestone for next-generation chip stacking: fully functional 2.5 V SOI CMOS devices fabricated at 400°C. The devices match electrical performance of devices fabricated at standard thermal budget (>1000 °C), removing one of the last barriers to large-scale 3D sequential integration (3DSI) —a core objective of FAMES.
Enabled by advanced CEA-Leti expertise in low-temperature processes (nanosecond laser annealing (NLA) and solid-phase epitaxy regrowth (SPER)), this work offers true three-dimensional device stacking from the lab to fab. 3D sequential-integration interconnection density between tiers is the highest among 3D technologies, such as TSV and hybrid bonding. In this project, CEA-Leti demonstrated that Si CMOS is BEOL compatible, and thus can be stacked safely above BEOL, while transistor performance and maturity overtake largely the other technological options from the state-of-the-art, low-temperature solutions.
The achievement, presented today in a paper at IEDM 2025, titled, “High Performance 2.5 V n&p 400 °C SOI MOSFETs: A Breakthrough for Versatile 3D Sequential Integration,” is a key breakthrough for the FAMES Pilot Line, a European Union initiative launched in 2023 in response to the EU Chips Act strategy to strengthen sovereignty and competitiveness in semiconductor technologies. By combining 3D heterogeneous and sequential integration on FD-SOI platforms, the consortium aims to enable a new generation of More-Than-Moore devices and applications.
Enabling New Chip Architectures
“This breakthrough is a major milestone of the FAMES project as it enables innovative new chip architectures,” said Dominique Noguet, CEA-Leti vice president and coordinator of the FAMES Pilot Line. “Our low-temperature process could accelerate real-world demonstrations of multi-tier stacks combining advanced CMOS logic, with smart pixel or RF layers, to create new high-performance 3D chips.”
Concept of 3-tier µLED GaN pixel allowing an emissive array with strong pitch reduction thanks to 3DSI in combination with 3D hybrid bonding technology. CEA-Leti’s 400 °C CMOS process enables such top-tier integration without exceeding the thermal limits of the active circuitry below.
The team showed that SOI devices processed at 400 °C instead of the high temperature (>1000 °C) industry standard and high-temperature industrial reference, performed equivalent to high-temperature devices.
“The 400 °C process enables 3D sequential stacking on any bottom tier,” Noguet said. “It’s a huge step forward because it’s far more mature—reliable and scalable—than current low-temperature solutions, such as polycrystalline films, oxide semiconductors or carbon nanotubes.”
Protecting Circuitry on Bottom-Tier LayersCEA-Leti’s team demonstrated n- and p-type transistors matching the characteristics of conventional high-temperature CMOS devices, while staying within the ≤400 °C thermal budget required to preserve active circuitry in lower layers.
The process relies on an optimized 400 °C LPCVD deposition for amorphous silicon followed by NLA in the melt regime for dopant activation and diffusion—producing polycrystalline, low-resistance gates with excellent interface quality. In addition, NLA-SPER mastering enables dopant activation without diffusion leading to access resistance within specifications.

Keysight & KT SAT Nail Industry First GEO-to-LEO Multi-Orbit NTN Handover!
Keysight Technologies, Inc., in collaboration with KT SAT, has demonstrated a successful non-terrestrial network (NTN) handover using the KOREASAT-6A satellite at KT SAT’s Kumsan Satellite Network Operation Center in Korea. In a controlled clinical environment, the companies established the industry’s first NR-NTN multi-orbit handover between a commercial GEO satellite and an emulated LEO link. The demonstration was performed over a live Ku‑band GEO connection (DL ~12.3 GHz / UL ~14.4 GHz), marking a major milestone toward testing the newly standardized 3GPP Rel‑19 Ku‑band NTN spectrum. By incorporating Ku‑band operation into this multi-orbit mobility scenario, Keysight and KT SAT have validated NTN behaviors in a frequency range now central to emerging global standards and operator deployment strategies.
As the industry moves toward 6G, integrating satellite and terrestrial networks is essential to deliver continuous coverage and resilient service in remote or disaster-affected areas. Satellite links, however, introduce longer delays, Doppler effects, and dynamic link conditions that complicate mobility and handover across space and ground domains.
By moving beyond earlier demonstrations focused on single-orbit GEO connectivity, KT SAT and Keysight have shown how operators can evolve from point-to-point satellite links to continuous multi-orbit mobility, expanding KT SAT’s service capabilities toward resilient, always-on coverage across space and ground domains. This achievement also establishes an important technical milestone for KT SAT and Keysight in advancing Ku-band NTN mobility.
Using Keysight’s Network Emulator Solutions and UeSIM RAN Testing Toolset, the teams emulated the base station and user equipment, established a two-way link through KOREASAT-6A, and maintained service continuity during a handover from GEO to an emulated LEO connection. Operating the GEO link in Ku‑band ensures that these mobility insights directly map to the Rel‑19 NTN frequency bands now entering commercial planning, giving operators and device vendors earlier visibility into real‑world propagation, timing, and interoperability behaviors. As a result, KT SAT can now explore and validate advanced NTN mobility scenarios in the lab, before satellites or user devices are widely deployed, accelerating its roadmap and reducing the time and cost of bringing new multi-orbit services to market.
This collaboration shows how operators can extend coverage and resilience, while device and chipset vendors gain a lab-based path to validate NTN mobility without relying solely on expensive field trials. Insights from this work are intended to inform standards discussions and operator evaluations, helping the ecosystem shorten time-to-trial and de-risk commercialization.
Seo Young-soo, CEO of KT SAT, said: “As the only satellite communications service provider in Korea, KT SAT is progressively validating the applicability of NTN gNB and UE using our five operational GEO satellites. Building on the results of this trial, we will actively explore strengthening the competitiveness of our next-generation GEO satellite for the global market and delivering integrated multi-orbit communication services based on NTN systems, including traffic handover across our own GEO and future LEO/MEO constellations.”
Peng Cao, Vice President and General Manager of Keysight’s Wireless Test Group, Keysight, said: “This demonstration shows how emulation can bring future multi-orbit networks into the lab today. By combining a live GEO connection with emulated LEO conditions using NR-NTN parameters in Ku-band, Keysight gives operators and vendors a practical way to study NTN handover behavior, optimize mobility strategies, and reduce the cost and risk of early deployments.”

DIY Film Capacitor 27.5nF
| I made this film capacitor yesterday with 2 ~4m nickel strips I had laying around (0.1mm x 11mm) with kapton tape as the dielectric. I wrapped it around a screw to form the shape and wrapped electrical tape around the outermost coil. Then I hot glued the uncovered coils to keep everything in place. I took the screw out and filled the void left behind with hot glue. The capacitor now measures around 27.5nF. I've been having trouble measuring held voltage with a DMM and oscilloscope. I think that's due to the inherent load the voltmeter and oscilloscope add. Nonetheless, my TC1 and my Kaiweets DMM both calculate around the same capacitance. This isn't really useful to me, but the nickel strip I had lying around was even less so, so I think this is a cool trinket. [link] [comments] |
Low-power Wi-Fi 6 MCUs preserve IoT battery life

Renesas has announced the RA6W1 dual-band Wi-Fi 6 wireless MCU, to be followed by the RA6W2 Wi-Fi 6 and BLE combo MCU. Based on an Arm Cortex-M33 CPU running at 160 MHz, these low-power microcontrollers dynamically switch between 2.4-GHz and 5-GHz bands in real time, ensuring a stable, high-speed connection.

The RA6W1 and RA6W2 MCUs use Target Wake Time (TWT) to let IoT devices sleep longer, extending battery life and reducing network congestion. They consume as little as 200 nA to 4 µA in deep sleep and under 50 µA while checking for data, enabling devices to stay connected for a year or more on a single battery. This makes them well-suited for applications requiring real-time control, remote diagnostics, and over-the-air updates— for example, environmental sensors, smart home devices, and medical monitors.
Alongside the RA6W1 and RA6W2 MCUs, Renesas launched two fully integrated modules designed to reduce development time and accelerate time to market. The Wi-Fi 6 (RRQ61001) and Wi-Fi 6/BLE combo (RRQ61051) modules feature built-in antennas, certified RF components, and wireless protocol stacks that comply with global network standards.
The RA6W1 MCU in WLCSP and FCQFN packages, as well as the RRQ61001 and RRQ61051 modules, are available now. The RA6W2 MCU in a BGA package is scheduled for release in Q1 2026.
