Defender Unveils Three Wolf Series II Military Vehicle Variants
Defender has introduced three variations in its range of military mobility at DVD 2026, the British Army’s leading defence and security exhibition. The new Tactical Mobility Vehicle, Mono-Tactical Mobility Vehicle and Utility Vehicle have been created as the initial variants in a family of military vehicles that is being built through JLR’s Defender Defence Division.
Based on Defender’s dedicated D7x platform architecture, Wolf Series II adopts monocoque construction, negating the need for a traditional body-on-frame setup. JLR claims the approach delivers a more rigid platform, enables higher payloads, and provides a base for adaptation to specific military uses. The architecture is said to deliver a torsional rigidity of 29kNm per degree.
The three variants have been specified according to the UK Ministry of Defence Light Mobility Vehicle tender specifications. Defender expects to be able to supply the platform to NATO defence agencies. In addition to the three variants, other possible configurations include a general-purpose platform, command-and-control vehicle and battlefield ambulance. JLR says the Defender platform has undergone over 62,000 engineering sign-off tests, traversed deserts, snow and ice caps, high altitude environments and extreme off-road conditions.
In addition to military radios, sensors, electronic countermeasures, command and external power systems, the platform could also carry other items depending upon what the customer may want. For readers in India, the programme is more important as JLR is owned by Tata Motors Passenger Vehicles. Wolf Series II shows how a commercially derived platform can be emplaced, electronically configured, and manufactured for today’s needs of tactical operations.

GM Defence Accelerates PAC-3 MSE Missile Component Production
GM Defence has produced its first lots of missile housing assemblies for Lockheed Martin’s Patriot Advanced Capability-3 (PAC 3) Missile Segment Enhancement (MSE) interceptor, showcasing how its automotive production expertise can accelerate defence manufacturing scale-up. It is understood that the first lots of components were produced just 22 days after the firm signed its manufacturing agreement on 6 August 2026. Items that normally take months to produce were provided to Lockheed Martin on 28 August.
The PAC-3 MSE is the most sophisticated interceptor in the Patriot air-and-missile-defence system. Whereas many missile systems primarily utilize explosive fragmentation for neutralization, PAC-3 MSE utilizes “hit-to-kill” technology by destroying ballistic missiles, cruise missiles and other threats in flight through direct impact. PAC-3 MSE’s operation depends on precise navigation, high-performance control electronics, a strong missile-rocket motor, and nearly real-time communication with the patriot system.
This partnership enables GM Defence to leverage automotive expertise in high-volume production, quality systems, industrial automation and supply-chain management. Lockheed Martin is investing heavily in the production of the PAC-3 MSE, Terminal High Altitude Area Defence System, and other precision-guided missile systems as the global demand for missile-defence systems continues to grow.
The fact that this is happening is in itself important, since many defence companies have long product lead times and often rely on a handful of specialised suppliers. Engaging a major automotive manufacturer in the supply chain might increase production and supply-chain diversity. The undertaking illustrates the value of taking commercial manufacturing of sophisticated military systems more rapidly while maintaining the precise quality needed for missile parts.

Lockheed Martin Unveils AIM-260 JATM for Next-Generation Air Combat
US Air Force has released cutting-edge missile against China. Lockheed Martin has launched the AIM-260 Joint Advanced Tactical Missile (JATM). It’s a new air-to-air missile that helps US fighter jets shoot down ever more technologically advanced rivals in contested airspace. The program has remained very secretive throughout its development, and much remains unknown about the missile.
The AIM-260 is an upgrade for the AIM-120 Advanced Medium Range Air-To-Air Missile (AMRAAM). It will probably have a longer range than the AIM-120, with the ability to target “extremely low observability, highly agile threats.” The missile system is being prepared for integration with future US combat aircraft, including the F-22 Raptor and F-35 Lightning II. The system is expected to be fitted with advanced electronic guidance systems, a data link, and anti-jamming features. This would give the missile the ability to receive updated targeting data after launch and to function in a jamming environment.
Lockheed has also agreed with the US Department of Defence to ramp up production to increase capacity, bolster the missile supply chain and facilitate multi-layer buying. Australia has also progressed with a plan to buy JATM as part of a proposed weapons package. The AIM-260 is an evolution of how air warfare is conducted, where fighters fight at increasingly great distances without giving away their position. The missile’s development also showcases how important small hardware processors, radar-seeker technology, resilient data links, and electronic-warfare resistance are in new missiles.

Gartner Reveals Top Government Technology Trends for 2026: AI, Cybersecurity and Digital Transformation
Gartner, a business and technology research and advisory company, has released its list of the top technology trends in government for 2026. The trends highlight increasing pressure on public sector leaders to transform operations and risk management, strengthen cyber resilience, govern AI at scale and meet rising citizen expectations amid macroeconomic and geopolitical uncertainty.
Dean Lacheca, VP Analyst at Gartner, said, “Government CIOs are operating in one of the most disruptive periods in recent memory. AI is reshaping how governments deliver services; cyber threats are evolving faster than traditional defenses can respond; and agencies are under increasing pressure to achieve more with finite resources. The challenge is no longer identifying technology opportunities, but building organizations that can adapt quickly enough to capitalize on them.”
Government technology leaders should assess how the following trends will influence investments, operating models and service delivery strategies in 2026 and beyond.

As governments move beyond AI experimentation toward enterprise-scale adoption, AI agents are emerging as a key catalyst for transformation. Agentic AI will increasingly support government operations, enhance citizen experiences, accelerate software development and automate routine decision-making processes.
“The conversation around AI must shift from technology implementation to organizational transformation,” said Lacheca. “Success with agentic AI will depend on modern governance, workforce readiness and the ability to redesign business processes, while creating an adaptable foundation for future innovation.”
Gartner research indicates that many governments are already exploring governance frameworks, digital identities and operational models to support the growing use of AI agents. They must also establish outcome-based AI roadmaps and develop clear metrics to measure value from AI investments.
Trend 2: Cybersecurity Requires an ‘Always Evolving’ CultureAdvances in AI, increasing geopolitical tensions and the emergence of quantum computing are fundamentally changing the cybersecurity landscape. Government organizations must move beyond periodic reviews and compliance-driven approaches toward adaptive, continuously evolving cyber strategies.
“Cybersecurity can no longer be treated as a static function,” said Lacheca. “AI is reducing the time between the discovery of vulnerabilities and their exploitation, while quantum computing is forcing governments to rethink how they protect sensitive information. Resilience, automation and crypto agility must become core components of every cybersecurity strategy.”
Gartner recommends government organizations automate security operations where possible; improve digital supply chain visibility; establish post-quantum cryptography readiness plans; and strengthen governance around data sovereignty and third party risk.
Trend 3: Reimagining Government Technology Service DeliveryEmerging technologies, increasingly digitally literate workforces and demand for new technical skills and capabilities are forcing governments to rethink how technology services are delivered. Future-ready organizations will be built around digital and AI literate workforces. This means technology service delivery will require adaptive operating models and governance structures that enable technology innovation across the organization while maintaining accountability.
“Technology will only ever be a tool or a trigger; transformation is ultimately about people,” said Lacheca. “Government IT areas that maintain their relevance will be the ones that invest in workforce capabilities, redesign how work gets done and build a technology operating model that can evolve as quickly as technology itself.”
According to a Gartner survey of 1,219 CIOs and IT leaders conducted in January 2026, 78% of government respondents anticipate investing in their people to advance their key technology initiatives. Gartner recommends they focus on prioritizing AI literacy, workforce modernization and organizational flexibility to meet growing service demands, while improving operational efficiency.

Unmasking the ghosts in your grid with power quality analyzers

Power that looks perfect can still betray you. Hidden distortions in the mains lurk behind flawless root mean square (RMS) readings—waiting to trip up even the best‑designed systems.
You’ve built the device exactly to spec, tested it in the lab, and watched it run flawlessly—only to have it mysteriously reset, flicker, or fail once deployed in the field. The nightmare begins when your trusty digital multimeter (DMM) or scope insists the mains are rock‑solid at nominal RMS, lulling you into false confidence.
In reality, hidden sags, swells, harmonics, and transients are wreaking havoc beneath that “perfect” reading. This is where a power quality analyzer (PQA) steps in—the engineer’s ultimate diagnostic lens for uncovering the real-world anomalies that standard tools simply cannot see.
An oscilloscope is the sprinter—built for speed, capturing fleeting microsecond transients in a narrow time window. It’s invaluable for spotting fast spikes but blind to the bigger picture.
A power quality analyzer (PQA), on the other hand, is the marathon runner—continuously logging over hours or days, aggregating long-term trends, tracking intense inrush currents during equipment startup, and checking compliance against standards like IEEE 519. Where the scope gives you snapshots, the PQA delivers the full story of your mains health.
Scopes give you snapshots, DMMs give you averages, but PQAs give you the truth—continuous visibility into harmonics, sags, swells, and transients that silently sabotage systems. If you want to design for the real world, you need to see the grid as it really is: noisy, imperfect, and unpredictable.

The rogue’s gallery of power quality villains
Three hidden villains—harmonics, sags and swells, and transients—quietly sabotage “perfect” power until a PQA exposes them.
- Harmonics – the waveform polluters: Nonlinear loads such as switching supplies, LED drivers, and variable frequency drives (VFDs) gulp current in pulses instead of smooth sine waves. Those pulses spawn integer multiples of the fundamental 50 Hz/60 Hz frequency. To quantify this mess, engineers look beyond total harmonic distortion (THD) to total demand distortion (TDD), preventing misleading percentage readings when equipment runs at light loads. In practice, “Triplen” harmonics—specifically the odd multiples of the third (3rd, 9th, 15th, etc.)—pile up in the neutral conductor, driving overheating, high crest factors, and insulation breakdown that can cripple systems.
- Sags and swells – the voltage rollercoaster: Large inductive loads like motors or HVAC compressors can drag voltage down to 85% of nominal, enough to brown‑out a microcontroller in an instant. On the flip side, when heavy loads shed or phases drift out of balance, the line can swell, stressing insulation and sensitive electronics. These rollercoaster swings slip past a DMM but are tracked relentlessly by a PQA.
- Transients – the semiconductor killers: Lightning strikes, capacitor bank switching, or routine grid events can unleash sub‑microsecond, high‑energy impulses. These spikes punch straight through ESD diodes and input protection, leaving semiconductors scarred or destroyed. A PQA captures these assassins in action, providing the context that scopes alone often miss.
Visual interpretation: The phasor diagram
One of the most practical screens on a PQA is the phasor display—a live map of voltage and current vectors that instantly reveals system health. A balanced three-phase system shows vectors neatly spaced at 120° with equal lengths, but any angular deviation or unequal magnitudes signal phase imbalance, a silent motor killer that drives counter-torque and winding stress.
Equally important is the power factor: the angular gap between voltage and current vectors tells the story of displacement power factor (DPF), with lagging angles exposing inductive loads and leading angles flagging capacitive behaviour. However, because modern switching supplies also introduce distortion power factor via harmonic wave shaping, a PQA is vital to calculate the true power factor—ensuring you aren’t paying penalties for hidden inefficiencies that standard meters completely miss.

Two sidenotes
First, while engineers often use these terms interchangeably when looking at a PQA screen, there is a distinct technical difference: a vector diagram maps static, space-dependent quantities with a magnitude and a fixed directional orientation (like mechanical force or magnetic fields), whereas a phasor diagram is a frozen snapshot of a constantly rotating, time-dependent AC waveform.
Because all three phases in a stable grid spin at the exact same frequency, “stopping the clock” allows the PQA to display their angular relationships cleanly on a 2D plane. In short, all phasors can be mathematically treated and plotted as 2D vectors on a screen, but if it represents a repeating, alternating AC waveform, it’s technically a phasor.
Second, while traditional PQAs capture localized, steady-state anomalies, phasor measurement units (PMUs) provide real-time, wide-area situational awareness across modern power grids. By utilizing GPS time-synchronization, PMUs measure electrical waves across geographically disparate locations simultaneously.
They sample voltage and current waveforms at high speeds—typically 30 to 120 observations per second—to deliver time-stamped synchrophasor data. This precision tracking of phase angles and magnitudes allows grid operators to detect dynamic instabilities, monitor wide-area power oscillations, and prevent wide-scale blackouts in increasingly complex, renewable-heavy distribution networks.
Beyond the basics: Today’s PQA landscape
Modern PQAs go far beyond the fundamentals. They’re now Class A certified under IEC 61000‑4‑30 Edition 3, tuned to detect supraharmonics in the 2–150 kHz band from EV chargers, solar inverters, and LED drivers. They are capable of microsecond‑level transient capture with sampling rates approaching 1 MHz.
A sidenote on supraharmonics – the new phantom: Classic harmonics stop at the 50th or 63rd order, but these higher‑frequency disturbances don’t just stress wiring—they interfere with IoT devices, smart meters, and communication systems, making them a new frontier for power quality monitoring.
Take a real‑world example. During EV charger rollouts in several European cities, utilities discovered that chargers injecting switching noise around 20–25 kHz were confusing smart meters. The supraharmonic interference overlapped with PLC communication bands, causing meters to misreport consumption data and triggering billing errors. PQAs tuned for the 2–150 kHz band exposed the culprit, proving that supraharmonics aren’t just abstract lab phenomena—they can directly disrupt grid intelligence and customer trust.
At the same time, IEEE 519‑2022 has tightened harmonic distortion limits at the point of common coupling, reflecting today’s nonlinear load environment and ensuring compliance reporting is more rigorous than ever. With cloud dashboards, automated reporting, and integration into data centres, renewable systems, and utility grids, PQAs have become essential tools for navigating a world where distributed energy resources make power quality more unpredictable than ever.
Building a DIY power quality analyzer
Building a DIY PQA is an incredibly rewarding, multi-disciplinary challenge that bridges the gap between embedded design, real-time digital signal processing (DSP), and high-voltage safety. To accurately capture complex multi-channel dynamics—such as system unbalance, triplen harmonics, and ground faults—a scratch-built approach demands an agile microcontroller like the dual-core ESP32 sampling at upward of 10 kHz per channel to perform continuous Fast Fourier Transforms (FFTs) up to the 50th harmonic.
While developers looking to deploy high-speed, multi-channel discrete ADCs (such as the ADS131M08) can achieve synchronous sampling across all inputs without phase skew, those wanting to offload the heavy math entirely can leverage a specialized polyphase metering IC like the Analog Devices ADE7880.
ADE7880 utilizes an on-chip, hardware-isolated adaptive real-time monitoring (ARTM) harmonic engine to automatically track fundamental frequency drift and calculate full THD+N over SPI. No matter the architectural route, strict implementation of galvanic isolation via components like the ZMPT101B voltage transformer is non-negotiable to protect downstream hardware, and firmware must be thoroughly vetted using low-voltage AC-AC step-down transformers before introducing the system to live, lethal mains environments.

Figure 3. Simplified block diagram of ADS131M08 reveals a fully integrated, 8-channel signal chain architecture featuring independent PGAs, ΔΣADCs, digital filtering, and dedicated calibration blocks feeding into a centralized control interface. Source: Texas Instruments
Designing for the real world means accepting that the grid is noisy, unpredictable, and far from perfect. Hidden distortions, imbalances, and transients are not exceptions; they’re the rule. A PQA equips engineers to see beyond the illusion of “perfect power” and design systems that survive in the wild.
So, here’s the challenge: What’s the weirdest power‑quality phantom you’ve ever had to hunt down in the field? Share your story in the comments—because every anomaly teaches us something new about resilience.

Wireless Smart Dial with ESP32-C3 and BLE HID
A wireless smart dial replaces keyboard and mouse for repetitive operations: turn it to navigate menus, press it to send commands. Afraz Ali’s project uses an ESP32-C3 SuperMini board, an SH1106 128×64 OLED display, and a KY-040 rotary encoder. The whole thing works as a Bluetooth Low Energy HID controller, so the computer sees it as a wireless keyboard or mouse.
The main input is the KY-040 encoder: turning it scrolls through the menu on the display, pressing it selects the action. The ESP32-C3 then sends the corresponding command via BLE HID. The SH1106 OLED display is connected via I²C at address 0x3C and shows the interface. The encoder uses three GPIOs (CLK, DT, SW) with internal pull-ups configured by the firmware.
Basic architecture of the project
The firmware includes separate profiles for Auto/Universal, Windows, macOS, Android, and iPhone/iPad. This choice handles BLE HID limitations across different operating systems. Custom text macros and settings are saved persistently using the ESP32 Preferences library. The source code is available in Afraz Ali’s repository, where you’ll find ready-to-upload Arduino sketches.
For programming you need Arduino IDE, the ESP32 Arduino package, the Adafruit GFX library, Adafruit SH110X, HijelHID_BLEKeyboard, NimBLE-Arduino, and Lynx Serial Monitor. The project includes 11 digital GPIOs (PWM) and 4 analog inputs (ADC) on the ESP32-C3 SuperMini board. Afraz Ali’s repository contains all the necessary code.
Power and consumption of the ESP32-C3 boardThe ESP32-C3 SuperMini board supports USB or external power from 3.3 V to 6 V. Sleep consumption is about 43 μA, so the device can stay in standby for a long time. Estimated build time is 5 hours, suitable even for those taking their first steps with ESP32 and BLE.
The M274 360-degree encoder module can be used as an alternative to the KY-040 for applications requiring continuous rotation. Both encoders connect directly to the board’s GPIOs. The 128×64 pixel SH1106 OLED display is the component that makes the interface readable and tidy.
SH1106 OLED display
Assembly is simple: connect the OLED display via I²C at address 0x3C, wire the KY-040 encoder to the three GPIOs, and power the board via USB. The firmware handles the internal pull-ups, so no external resistors are needed. The project is compact and can be enclosed in a small 3D-printed case.
The dial works as a customizable physical control surface. You can assign keyboard shortcuts, multimedia controls, and text macros to each menu item. The device is useful for people working with editing, development, or office automation software.

Offline Wikipedia on ESP32: a whole encyclopedia on a cheap display
Putting an entire encyclopedia on a cheap display moves knowledge from the center of the network to its edge. Alun Morris’s project does exactly that: it turns the ESP32-2432S028 module, the 320×240 pixel Cheap Yellow Display, into an offline Wikipedia reader. Articles, images, and the search index live on a microSD card, and the device reads them without any internet connection.
The result is a standalone device that responds to touch and shows encyclopedia entries. The base is the Kiwix ZIM file, the same format used by offline Wikipedia projects on desktop. A preprocessor on a PC converts it into a binary database optimized for the ESP32’s limited resources. The firmware reads all content from there.
The preprocessor and data conversionThe starting point is the recommended ZIM file, wikipedia_en_simple_all_maxi, a download of about 3.3 GB containing roughly 285,000 articles. The preprocessor, written in Python 3.9+, uses libzim to read the file and converts it into a binary database. The processed size of Simple English Wikipedia is about 10 GB on the card.
The conversion is not a simple copy: the preprocessor cleans the article HTML, reduces images, and converts them into formats the ESP32 can decode. Photos become JPEGs with a default quality of 90, diagrams use the QOI format. Thumbnails have a maximum size of 320×212 pixels. Articles are also split into 32 MB chunks and images into 4 MB chunks, so the firmware can read them without saturating memory.
The build takes about 30–60 minutes on a modern PC and uses up to 4 CPU cores. The result is a database with fixed-width 80-byte records for the title index. For search, the firmware loads a sparse index into RAM with one entry every 64 articles, occupying about 7 KB. This allows quickly finding the scan point without reading the entire index from the card.
Firmware and ESP32 memoryThe firmware is written for PlatformIO and runs on the ESP32-2432S028 module, which mounts the ILI9341 display and the XPT2046 touchscreen. Memory is the main constraint: the ESP32 has about 300 KB of usable heap, while typical ZIM clusters are 1–4 MB, too large to handle at once. That’s why the preprocessor splits everything into smaller chunks.
The firmware’s minimal renderer handles the cleaned HTML and shows decoded images with TJpgDec for JPEGs and the qoi library for diagrams. Title search uses the fixed-width binary index and the sparse index in RAM, so even with 285,000 articles the response is immediate.
On first boot, the firmware performs touchscreen calibration and saves the data to flash for subsequent boots. This way the user doesn’t have to repeat the procedure every time. The project is documented in Alun Morris’s repository, where you can find the complete code, the preprocessor, and build instructions.
MicroSD card and practical limitsThe microSD card must be at least 8 GB: processed Simple English Wikipedia takes about 10 GB, so a 16 GB card is the safe choice. The CYD handles cards up to 32 GB, while 64 GB cards might work but without guarantees. The ZIM file to download is a single 3.3 GB download.
The project uses easily available components. Besides the ESP32-2432S028 module, you only need a microSD card and a USB cable for firmware upload. No other modules or sensors are required. Everything is powered via USB, like the ESP32 board with USB Type-C connector that many makers already have in their lab, although for this project the specific board is the CYD.
The main limitation is language: the Simple English version is meant for those with a reduced vocabulary, not for in-depth consultation. Also, images are thumbnails, not original versions. However, for those who travel, work in areas without coverage, or want a standalone educational device, this offline reader is a concrete and low-cost solution.

P.A.R.: a robot that draws pixel art by flipping disks
P.A.R. is a robot that draws black-and-white pixel art on a 37×18 grid of square disks called squisks. Instead of using a solenoid for each disk like traditional flip-disc displays, it uses a single mobile robot with a tool head to physically flip the disks. The result is a slower but much more economical process, suited to works of art.
The project is by Zimm, who built the robot with over a thousand 3D-printed parts and dozens of wires. The heart of the system is an Arduino Nano ESP32, which controls the two-axis CNC machine and manages the internet connection. The display is made up of 666 hand-assembled squisks, black on one side and cyan on the other.
The tool head and grid scanningP.A.R.’s tool head is custom-made and includes a color sensor, a servo motor, and a pin. Before printing, the robot performs a full scan of the grid with the color sensor to learn the current state of each squisk. This way it knows exactly which disks are already in the right position and which are not.
After the scan, the robot fetches the image from the request queue on the server. It flips only the squisks that need to change state, using the pin driven by the servo motor. Precision is key: each disk must be rotated 180 degrees to go from black to cyan or vice versa.
Once printing is complete, P.A.R. runs another scan to check for squisks that were not flipped correctly. If it finds errors, it corrects them right away. This verification loop makes the system reliable even with disks that might jam or not rotate perfectly.
Web connection and remote controlThe robot is connected to the internet via the Arduino Nano ESP32, which integrates Wi-Fi and Bluetooth. A dedicated website lets anyone send an image to print. The drawing is added to a request queue on the server, and the robot processes it when its turn comes.
This architecture makes P.A.R. an interactive installation: people can upload their own pixel art from any connected device. The code is available on GitHub, and Zimm’s project page collects the system details. The maker’s site also documents the hundreds of hours of work needed to build the robot.
For those who want to remake the project, the main components are few and accessible. The Arduino Nano ESP32 handles the logic and connectivity. The TCS3200 color sensor is a module with 4 white-light LEDs and a color-to-frequency converter, perfect for distinguishing the two sides of the squisks. The servo motor drives the pin that flips the disks.
The most challenging part is the mechanics. Over a thousand 3D-printed parts make up the frame, the axes, and the tool head. Assembling the 666 squisks requires patience and precision, but the result is a mechanical display unlike any other.
P.A.R. shows that you can build a low-resolution display without the cost of hundreds of solenoids. A single mobile robot, a smart tool head, and a bit of software are enough to turn a grid of disks into a pixel art canvas that can always be updated.

Radxa Linkr: A Pocket-Sized IP KVM for Browser-Based Remote Control
Radxa Linkr is a compact IP KVM that turns a computer into a machine you can control remotely, from anywhere. The device, about the size of a USB stick, connects to the target PC via HDMI for video and USB for keyboard and mouse. From then on, access happens through a web browser, with no need to install dedicated apps. You can manage the system even when it is off or during boot, for example to change BIOS settings.
Communication with the user happens over USB-C, Ethernet, or WiFi 6, in both client and access point modes. This means you can reach the device from a local network or from the internet, perhaps through a VPN. In addition, built-in support for Tailscale VPN and two-factor authentication makes the connection more secure. Everything is managed by a web interface that works on any operating system.
Hardware and components of Radxa LinkrThe heart of the device is the Rockchip RV1106G3 SoC, which integrates an Arm Cortex A7 CPU at 1.2GHz with a RISC-V co-processor. The 1 TOPS NPU handles AI processing, while the third-generation 5MP ISP and VPU support H.265/H.264 encoding up to 3072×1728 (5MP) at 30fps. System memory is 256MB DDR3L on-chip, with optional storage via a 16GB eMMC flash.
For video capture, the board uses an HDMI-to-MIPI CSI bridge (Rockchip RK682F) that supports inputs up to 2K at 30Hz. Connectivity is handled by a WiFi 6 module (AIC8800) and a RealTek RTL8152B Ethernet port. Power is 5V/2A via the USB-C port, and overall dimensions are just 70 x 22 x 12 mm. The price starts at $59 on AliExpress, Amazon, Arace, and Allnet.
The project page on the maker’s site documents the technical specifications and usage modes. In addition, the system supports advanced features such as integration with AI agents like OpenClaw and Hermes, which can automate diagnostic or maintenance operations on the remote computer.
Operation and browser accessAccess to Radxa Linkr happens through a web browser, with no dedicated software needed. Once the device is connected to the network, you open its web interface and configure the connection to the target computer. The interface shows real-time video and lets you use keyboard and mouse as if you were in front of the machine. You can also change the video resolution and manage multiple devices from a single panel.
The device also works before the operating system boots, so you can access the BIOS or bootloader. In addition, WiFi access point mode lets you connect directly to Linkr when no network is available. For those who need a stable connection, the Ethernet port offers a valid alternative to WiFi. Finally, the USB-C port can be used for power or for a direct connection to a PC.
Radxa Link web interface
Power management is efficient thanks to the low-power SoC, but it is important to power Linkr with a 5V/2A adapter to ensure stability. As for cables, a good-quality HDMI cable is essential to avoid video interference. Also, if you want to extend the distance between Linkr and the computer, you can use a longer HDMI cable, but it is advisable to keep the USB connection short to avoid power issues.
A 5-meter HDMI 2.1 cable can be useful for placing the device in a convenient spot while maintaining video quality. However, for the USB port it is better to use a short, shielded cable. In addition, for those who want to expand logging capabilities, a MicroSD Card Reader module with SPI interface can be connected to save diagnostic data or video recordings.

Tip: "no-clean" solder paste - clean it!
| "no-clean" solder paste leaves really messy looking residues having fine pitch connectors (looks like a cracked salt deposition). The pictures show the before and after cleaning using an ultrasonic bath and flux remover agent (bath ph = 12, 50 °C, 5 min). Cleaning with isopropanol and flux-off using brushes did not work at all (hard to find a suitable brush, hair size vs hair hardness). Conclusion: Always clean your boards for best results. Connector pad specs: - 400 um pitch - 200 um pad width - 100 um mask dam (sliver) - 50 um mask expansion [link] [comments] |
Lumina Desk: The Restaurant Table That Takes Orders by Voice
Lumina Desk is a restaurant table that takes voice orders, without apps, QR menus, or waiters. A Raspberry Pi with microphone, speaker, and ePaper screen manages the entire cycle: the guest speaks, the system transcribes, interprets, shows the order on the display, communicates it to the kitchen, and collects payment via UPI QR. The project is by Shubhjaiswal408, and Shubhjaiswal408’s repository contains all the code to rebuild it.
The heart of the system is wake-word detection for ‘Hey Lumina’, handled by the on-device openWakeWord model. Once woken, the microphone captures the guest’s voice and transcribes it with Groq Whisper (whisper-large-v3-turbo) if there’s a connection, or with Vosk in offline mode. The text is then passed to an LLM, GPT-OSS-20B online or LFM2-700M offline, which interprets the intent. However, prices, wait times, and allergens are never left to the model: they are calculated in Python from the restaurant’s real menu.
For the most common requests, like ordering a pizza, asking for the bill, or checking an allergen, the system doesn’t even go through the LLM. A rule parser classifies them in under 5 ms, making the experience almost instantaneous. Additionally, the menu of the Auntyno-Z Pizza restaurant in Ghodasar includes 189 dishes, of which 66 are pizzas, and the parser handles them all without a hitch.
The data flow: from voice to order in the kitchenOnce the request is interpreted, the order state is published to an MQTT bus. Two services subscribe to this bus: the first generates an 800×480 pixel image and sends it to the ePaper panel on the table, so the guest sees the summary in real time. The second is the kitchen dashboard, which receives the order ready for preparation. This approach separates recognition logic from display, making the system modular and easy to extend.
Payment happens via a dynamic UPI QR code showing the exact bill amount. Payment confirmation is read directly from the merchant’s emails via IMAP, so the system knows when the order has been settled and can reset the table for the next customer. Everything runs on a single Raspberry Pi, which also handles confirmation audio through the speaker.

The project aims to work even without an internet connection, an important choice for a noisy environment like a dining room. In offline mode, transcription uses Vosk and interpretation relies on the LFM2-700M model via Ollama. This 700M-parameter model runs on the Raspberry Pi’s CPU and takes about 9 seconds for processing. That’s an acceptable time for an order, but it shows the trade-off between accuracy and speed when working without the cloud.
To reduce wait times, the rule parser intercepts most phrases. For example, if the guest says ‘I’d like a margherita’, the parser recognizes the pizza, calculates the price from the menu, and publishes the order to MQTT without ever calling the LLM. This way, the system feels responsive in daily use and reserves the 9 seconds of computation only for more complex questions.
For voice synthesis of confirmations, the system uses Piper, a lightweight text-to-speech engine. Finally, image generation for the ePaper screen is handled by the Pillow library, which composes the order summary with high readability. Everything is orchestrated by Python scripts that communicate via MQTT, keeping the code clean and adaptable to other restaurants.
Anyone wanting to replicate the project will find in Shubhjaiswal408’s repository the code for speech recognition, menu management, and MQTT integration. The system was designed for a real restaurant with 189 dishes, so it’s not a demo: it’s a device that has faced noise, different languages, and the need for reliability. For hardware, the Raspberry Pi 5 with 2 GB is an adequate base, although the original project uses an earlier model. The 2 W speaker is sufficient for the short voice confirmations at the table.
