Bridge Data Centres (BDC), a Singapore-headquartered hyperscale data centre provider, and Morong Electric, an electrical manufacturing specialist, have launched PowerCore 5.0, the world’s first fully prefabricated power module designed for high density AI data centres.

Built for high-density AI workloads on accelerated deployment timelines, the module complies with the technical standards of BDC’s proprietary i-Power Cube, its power system designed for high-performance computing. It integrates seamlessly with the Bridge Omni Platform, BDC’s modular intelligent infrastructure platform for the AI era. PowerCore 5.0 combines BDC’s global hyperscale delivery experience with Morong Electric’s end-to-end electrical manufacturing expertise.

Rapid AI advancement has driven rack power densities from 10kW to more than 100kW, placing stringent new demands on mission-critical power infrastructure. Traditional delivery models, which rely on fragmented procurement and on-site system integration, struggle to cater to the rigorous requirements of AI-optimised data centres. Drawing on BDC’s global campus delivery footprint and Morong Electric’s electrical engineering expertise, PowerCore 5.0 addresses these challenges through four core design attributes: factory pre-integration, standardised global transport, parallel construction and maintenance without downtime.

Factory pre-integration

Each unit integrates transformers, power distribution, uninterruptible power supply (UPS), cooling, fire suppression and monitoring systems into a single module, fully assembled and tested off-site. Site teams need only complete the final cable connections on delivery, removing the quality inconsistencies that accompany conventional field construction.

Standardised global transport

Built on a standard 40ft ISO container frame, the module integrates seamlessly with global shipping networks, eliminating oversized freight premiums, dedicated transport and protracted customs delays that hinder cross-border deployments. Purpose-engineered for BDC’s core markets, it complies with local climatic benchmarks and industrial standards to enable dependable global rollout.

Shortened delivery timelines by more than 50%

On-site civil works and factory prefabrication proceed simultaneously, shortening total delivery timelines by more than 50% compared with conventional build methods. Large campuses can deploy units on a bi-weekly cadence, matching the rapid scaling and flexible capacity expansion that AI demands.

Maintenance without downtime

In an industry first, core components including UPS units, transformers and precision cooling are mounted on slide-out rails. Technicians can withdraw and service individual units without interrupting power to the data centre, keeping high-density compute clusters running around the clock.

Mr Zhang Binghua, Chief Technology Officer of BDC, said, “The AI infrastructure sector is scaling at an unprecedented rate, and operators now require higher power density, faster hardware refreshes and maximum uptime. This shift requires us to rethink how power systems are designed and deployed. PowerCore 5.0 raises the bar on system integration, cross-climate operation, delivery speed and intelligent operations and maintenance. It will enable standardised, low-carbon compute deployments across the globe and provide the stable power foundation to support the continued growth of the global AI ecosystem.”

Mr Zhang Kai, Chairman of Morong Electric, said, “AI hardware now evolves on a monthly cycle, and traditional on-site system integration can no longer keep pace with the operational needs of modern AI data centres. Prefabricated power modules clear the delivery bottlenecks holding back compute infrastructure expansion. This launch marks a critical milestone in our strategic partnership, and we will continue to co-develop high-performance, integrated power solutions that meet global market standards and regional compliance requirements.”

BDC and Morong Electric will continue to develop prefabricated power modules engineered for ultra-high-density compute and cross-border regulatory alignment. Both companies aim to advance industry-wide technical standardisation and the collaborative development of compute infrastructure. Their low-carbon, modular power solutions will support the sustainable and scalable growth of AI operations across international markets.

The shelf is a 24 V tunable white strip driven by an off the shelf controller. At full brightness it made a high pitched wine. Dimmed to a usable level, it got even worse! Scoping the original controller’s output showed it drives the LEDs with a 2 kHz H-bridge waveform, and dimming inserts 0 V dwell that pumps energy into the harmonics right where your ear is most sensitive. A mic 5 cm away confirmed it, a harmonic comb spaced at 1999 Hz, with the 4 kHz member 16 dB louder when dimmed. The replacement is an STM32 driving a three level H-bridge at 25 kHz through a proper gate driver, BLE control, on a 4 layer board sized to drop into the original enclosure. Every harmonic now lands above the audible band. Current draw came out the same as the original, so the silence was basically free. It also remembers brightness and colour through power cuts, the F303 has no EEPROM so state gets debounced into a flash page.

I like to read about research innovations even if most of them don’t represent in an advance that can be commercialized or even leveraged to boost technology in general. Sometimes, the work that the team has done demonstrates innovation, discusses ways they addressed and hopefully resolved problems, and even gives insight into areas where there are remaining barriers to overcome.

That’s the case with a research paper I came across on use of paper as a substrate of passive electronic components and interconnects. In the work, “High-Density Papertronics via Laser-Written Hydrophilicity on Hydrophobic Parchment Paper” published at ACS Applied Materials & Interfaces, researchers discuss the long path they have taken to develop their latest effort in paper electronics—dubbed “papertronics”—with the use of standard parchment paper as a substrate for passive electronic elements.

This project builds heavily on other work the team has done under Professor Seokheun “Sean” Choi of the Department of Electrical and Computer Engineering at Binghamton University’s Thomas J. Watson College of Engineering and Applied Science (New York State). They have investigated the use of paper to create fully biodegradable circuit elements such as batteries, sensors, and other components.

The papertronic devices are intended to be low cost, environmentally friendly, and suitable for applications such as single-use medical patches that power using sweat, water, or even saliva as their working fluid. While paper-based electronics of various types are being investigated in many labs, this group has done a significant amount of leading-edge work in this area with a lengthy track record.

Their previous attempts to build passive circuit elements used chromatography paper as a substrate; this paper is a specialized, high-purity cellulose material widely used as the stationary phase to separate mixtures of chemical substances, inks, or plant pigments via capillary action. Unlike everyday normal paper, which contains fillers and sizing agents that interfere with fluid movement, chromatography paper has a consistent texture, controlled thickness, and predictable capillary action, vital for accurate laboratory results.

That approach proved the concept but revealed a stubborn limitation: the wax barriers used to define circuit features blurred and spread when heated, limiting the smallest achievable features to about a millimeter. That kept circuits large—on the scale of tens of centimeters—and prevented the kind of compact, tightly packed designs needed for practical applications.

Rethinking the problem

Their new approach required a radical shift. Instead of hydrophilic chromatography paper, they switched to hydrophobic parchment paper, and using a laser to selectively create hydrophilic channels rather than wax to create hydrophobic barriers, the team inverted the entire fabrication paradigm (Figure 1).

Figure 1 By targeting the parchment paper with a laser, Professor Choi and his team removed the silicone coating to expose water-absorbing cellulose fibers. The channels then act as microscopic highways that guide water-based conductive inks to form electronic circuits. Source: Binghamton University

Note that parchment paper—also called “baking paper”—is a heat-resistant, silicone-coated paper used in cooking and baking as a non-stick, greaseproof surface; you can buy it at almost any supermarket as well as from cooking-supply sources. But there’s some potential for verbal confusion here; the research team is using silicone-based paper as the substrate rather than more-familiar “silicon.” Silicone, of course, is a synthetic rubber-like substance made by combining silicon with oxygen, carbon, and hydrogen.

They developed hybrid paperfluidic-electronic techniques that exploit parchment paper’s capillary action to wick functional materials into predefined regions, yielding components such as resistors, capacitors, inductors, and interconnects (Figure 2).

Figure 2 Conceptual illustration of wax-printed versus laser-induced papertronics. In row (a), wax-printed papertronics on hydrophilic cellulose paper highlights the multiple fabrication steps required for hydrophilic pattern formation via single-sided wax printing and thermal penetration (i) and hydrophilic patterning via asymmetric double-sided wax printing and thermal penetration (ii). In row (b), molten-wax spreading during thermal penetration inherently blurs feature boundaries and limits the achievable resolution. Laser-induced papertronics on hydrophobic parchment paper demonstrates a simplified, low-temperature fabrication workflow that enables direct hydrophilic patterning without wax spreading or high-temperature processing (i) and the realization of high-density papertronic circuits with narrow hydrophilic channels and tightly spaced insulating regions (ii). Source: ACS Publications

The result is circuit features as small as 250 micrometers wide with 300-micrometer spacing—a twofold to threefold improvement over the best wax-based methods, and small enough to fit complete filter circuits into a footprint measured in millimeters rather than centimeters.

The differences due to the inverted thinking are clear: with chromatography paper, they were fighting against molten wax spreading through the paper. With their laser approach and parchment paper, the pattern is defined by the laser spot size and stays exactly where they put it. There is no spreading, no blurring, and no uncertainty.

Critically, all of the functional inks used in the work are water-based and free of toxic metals or organic solvents. The circuits are biodegradable, breaking down in soil within weeks, and can be incinerated to ash in seconds if rapid disposal is needed. For applications that require longer operational lifetimes, a thin silicone encapsulation layer protects the devices from humidity and mechanical damage without affecting their electrical performance.

Fabrication technique

As a first step, they used Fourier-transform infrared (FTIR) spectroscopy to determine the chemical composition of the pristine parchment paper, the surface modifications induced by laser treatment, and the effect of “ink” deposition. Laser irradiation induces pronounced photothermal and photochemical modifications to the parchment paper surface, which they assessed as well.

They then used laser modification to convert selected regions into ink-guiding hydrophilic microchannels. The localized laser-induced heating modifies the surface chemistry and microstructure without requiring additional chemical coatings, fillers, or high-temperature treatments.

Using a 50-watt CO2 laser, the laser power and scan speed were systematically tuned to optimize local heating and patterning of silicone-coated parchment paper. It took a significant amount of trial and error to find the optimum power and speed pairing. With a high-power and low-scan speed, the laser overheated the substrate, burning through the hydrophilic cellulose layer and cutting the paper. At low power and high speed, the silicone coating was only partially removed or not removed at all, thus preventing proper penetration of the functional materials.

Critically, these laser-defined hydrophilic features exhibit no lateral spreading, enabling minimum feature sizes and spacings that approach the theoretical resolution limit of the optical system. This strategy enables unprecedented high-density patterning, robust pattern reproducibility, and device-scale miniaturization for a significant leap beyond what is achievable with wax printing or traditional paperfluidic techniques.

For ink used to define conductive traces and electronic components, they used poly (3,4-ethylenedioxythiophene)-poly (styrenesulfonate), known as PEDOT:PSS, with controllable viscosity and density. For many reasons, PEDOT:PSS is widely used in research projects. Using these formulations resulted in limited lateral spreading on the order of micrometers within 3D cellulose fiber network.

Then there’s performance

They constructed printed resistors, interdigitated capacitors, low-loss interconnects, and integrated low- and high-pass RC filters within a single paper layer, exhibiting predictable, tunable electrical behavior consistent with circuit theory. The conductive lines have a width of ∼250 μm and a line spacing of ∼300 μm, corresponding to a PCB pitch of ∼550 μm.

The team demonstrated the platform’s versatility by fabricating a complete set of electronic components on paper: resistors whose resistance can be tuned over three orders of magnitude simply by adjusting the ink formulation; interconnects with sheet resistance as low as approximately one ohm per square, rivaling rigid electronic systems; capacitors tunable from microfarads to millifarads; and fully functional low-pass and high-pass RC filters whose frequency response closely matches theoretical predictions.

For example, the resistor values were independently controlled through three parameters: ink concentration, dimethyl sulfoxide (DMSO) content, and resistive line length. The laser-defined hydrophilic channels acted as deterministic templates that confined conductive inks, while the surrounding silicone-coated parchment remained hydrophobic and electrically insulating. This spatial confinement decoupled electrical tuning from uncontrolled ink spreading and penetration, enabling predictable and reproducible resistor geometries.

Note that DMSO is a poor electrical conductor on its own because it’s a molecular liquid without free ions or electrons. However, when ionic compounds like salts or acids are dissolved in it, it acts as a polar aprotic solvent that readily dissociates those ions, allowing the resulting solution to conduct electricity.

The laser-defined hydrophilic channels act as templates that confine conductive inks, while the surrounding silicone-coated parchment remains hydrophobic and electrically insulating. This confinement decouples electrical tuning from uncontrolled ink spreading and penetration, enabling predictable and reproducible resistor geometries.

Overall, the resistance of the paper-based resistors can be continuously tuned over a broad range from approximately tens of ohms to several kilohms (Figure 3).

Figure 3 For paper-based resistors, schematic illustrates how laser-defined paper resistors are tuned by three independent parameters: ink concentration, DMSO addition, and resistor geometry (a). Optical microscopy image (i) and SEM image of the A–A′ cross-section of a representative resistor (ii) show that PEDOT:PSS is precisely confined within the laser-treated hydrophilic region and surrounded by untreated hydrophobic parchment paper (b). Measured resistance of resistors is fabricated with varying ink volumes, where PEDOT:PSS was systematically diluted with deionized water to concentrations of 100%, 75%, and 50%, plotted as a function of resistor length (c). Resistance as a function of DMSO concentration in the PEDOT:PSS matrix is shown with weight percentages ranging from 2% to 20%, plotted as a function of resistor length (d). Data in (c) and (d) represent mean ± standard error from at least 10 independent measurements per data point. Solid lines are least-squares linear fits. Source: ACS Publications

For capacitors, conductive PEDOT:PSS electrodes were precisely patterned into interdigitated fingers using laser-induced hydrophilic channels, while the surrounding silicone-coated parchment remains hydrophobic and electrically insulating. The capacitance increases monotonically with the number of interdigitated fingers, reflecting the enlarged effective electrode surface area and reduced ionic diffusion distance inherent to the interdigitated geometry.

They achieved capacitance values spanning from the low microfarad regime to over 1.2 millifarads (Figure 4). The ability to modulate capacitance over nearly three orders of magnitude using only electrolyte composition and electrode geometry demonstrated the exceptional tunability of this capacitor platform.

Figure 4 For paper-based capacitors, schematic illustrates a laser-defined interdigitated capacitor fabricated on hydrophobic parchment paper (a). Optical microscopy image (i) and SEM image of the A–A′ cross-section of a representative capacitor (ii) show that conductive PEDOT:PSS ink is precisely confined within the laser-treated hydrophilic regions to form interdigitated electrode fingers, while the surrounding parchment paper remains hydrophobic and electrically insulating (b). Measured capacitance of capacitors fabricated with varying H3PO4 concentrations in the PVA gel electrolyte is plotted as a function of electrode finger number (c). Galvanostatic charge–discharge (GCD) curves are measured at a constant current of 2 μA after different numbers of charge–discharge cycles (d). Capacitance retention as a function of cycling number demonstrates the cycling stability of the paper-based capacitor (e). Source: ACS Publications

Interconnects and filters

The capillary scheme was also used to create interconnects, leading to what can be considered as “integrated circuits”. To demonstrate circuit-level integration, they fabricated first-order low-pass and high-pass RC filters.

All of the hydrophilic regions were defined in a single laser step, and components were sequentially deposited using paper stencils. The first-order low-pass RC filter composed of a series resistor and a shunt capacitor (Figure 5).

Figure 5 For paper-based RC filters fabricated on parchment paper, part A shows a low-pass RC filter: schematic illustration (a), circuit diagram (b), and photograph of the low-pass filter fabricated on parchment paper (c). Frequency-dependent gain plots for low-pass filters with different resistance values (46 Ω, 95 Ω, and 150 Ω) demonstrate low-pass cutoff behavior (d). Part B shows a high-pass RC filter: schematic illustration (a), circuit diagram (b), and photograph of the high-pass filter fabricated on parchment paper (c). Frequency-dependent gain plots for high-pass filters with different resistance values (15 Ω, 46 Ω, and 95 Ω) demonstrate high-pass cutoff behavior (d). Source: ACS Publications

Since the resistor, capacitor electrodes, and interconnects required different ink formulations and additives, each printing step is performed using a dedicated paper stencil. Despite this, the overall process remains low-temperature and highly reproducible.

They also assessed environmental aspects and biodegradability. Although parchment paper incorporates a thin silicone coating to give it hydrophobicity, the substrate is predominantly cellulose-based with the silicone layer accounting for only a minor fraction of the total material volume (typically <2 μm in thickness).

As a result, degradation is governed primarily by the underlying cellulose fiber network. The silicone coating, while more persistent in natural environments, is widely recognized as biocompatible and chemically inert, and its limited mass minimizes its environmental burden.

But no transistors, at least not yet

The team’s paper is quite detailed with respect to the underlying materials science, elemental physics and chemistry, and other considerations. They also acknowledge a significant shortcoming; thus far, no active devices such as transistors.

I applaud their willingness to switch from one type of paper and fabrication to a very different scheme when the first approach reached a dead end. It takes an open mind to start over and re-assess what is working and what is not.

Based on their track record with various embodiments of papertronic devices, I wouldn’t be surprised if they get the needed funding to further pursue their work toward papertronic transistors using what they have learned thus far. That would certainly be impressive.

Today’s fun SMD soldering rework under the microscope. Tossed the penny in there for scale 🤓 submitted by /u/JennSNH [link] [comments]

Attempted prohibitions of foreign-sourced products based solely on theoretical claims, absent irrefutable supportive factual evidence, only invites domestic-supplier favoritism accusations.

Last year I went on a “bit” of a(nother) drone-buying binge. Following up on the first-generation DJI Mavic Air I’d bought in mid-2021.

And the two DJI Mini 3 Pro drones (once again, accompanied by an abundance of accessories) I’d acquired in mid-2024.

I got two more gently-used drone gear sets from Lensrentals in 2025; the computer vision-based collision avoidance surround-enhanced and LiDAR-augmented Mini 4 Pro.

Followed by a first-person view (FPV) “cinewhoop” drone, the first-generation DJI Avata.

And in-between those two acquisitions, chronologically speaking, was the first-generation DJI Neo I bought from Amazon in a three-battery kit configuration.

What was behind this seeming conspicuous consumption behavior? Curiosity, for one thing; FPV operation, for example, was something that had captured my interest ever since I first saw the famous “Right Up our Alley” video more than a half-decade ago.

An essentially autonomous (albeit optionally still traditionally controllable) drone with a starting price just slightly more than $100 was also intriguing, both personally and professionally.

And I’ve already mentioned the feature set enhancements the Mini 4 Pro offers over its Mini 3 Pro precursor, which were insufficient temptation in 2024 but which I succumbed to a year later once I came across a sufficiently discounted like-new version.

Heavy is the hand that holds the crown

That all said, scarcity fears were admittedly also a factor, driven by seemingly inevitable pending government regulation-driven bans on DJI drones, along with other image capture-capable devices from the company, such as vlogging and action cameras. Back in mid-2024, the U.S. House of Representatives had passed legislation introduced a year-plus earlier, which banned further sales of drones from DJI and other suppliers deemed too friendly to the Chinese Communist Party, despite a longstanding absence of any tangible (public, at least) evidence supportive of this stance.

Although, subsequently introduced in the U.S. Senate, it was never voted on, therefore not becoming a law. But that outcome was a false solace; U.S. Customs began blocking imports of DJI drones and other products that same October.

By mid-2025, U.S. retailer inventories of existing DJI devices had notably evaporated. And the company didn’t even bother formally introducing newer drones such as the Mavic 4 Pro, Mini 5 Pro, Neo 2, Avata 360 and Lito 1/X1 in the United States. That all said, as it turns out, the final ruling from the U.S. Federal Communications Committee (FCC), announced two days before Christmas 2025 (believe it or not), admittedly wasn’t as egregious as initially feared (although a further retroactive-recall carve-out remains in place).

Imports of future-announced drones, including future generations of existing drone lines, were prohibited. But existing drones were once again green-lit for shipment and sale, including ongoing firmware updates (for at least a few more years) and broader usage (subject to existing FAA regulations) for products already in customer hands. Which is why you can now find the Mavic 4 Pro, Mini 5 Pro, Neo 2, and Avata 360 for sale at some U.S. retailers.

But only some. Notably, DJI not only subsequently sued the FCC but doesn’t include its latest products on the U.S. version of its online store. Even legacy drones remain unavailable; they’re “out of stock”.

Equally disruptive, the company won’t honor warranty claims coming from U.S. residents for products purchased through third parties. And speaking of which, some large U.S. retailers, such as Amazon (but not others such as Adorama and B&H Photo Video, interestingly), are continuing to decline to inventory and sell the latest DJI drones themselves, although they’ll act as marketplaces and shippers for others.

Meanwhile, DJI is reportedly rebranding its products as coming from “shell” companies to dodge restrictions (at least temporarily). You can still buy anything you want, including supposed banned newer drones such as the Lito 1 and X1, from outside-U.S. sellers via eBay, Mercari, and other online marketplaces. And if you know anyone in Canada or Mexico, or briefly pop across the border or more broadly travel internationally yourself, you can also get your unconstrained DJI “fix” that way. So how much of a ban on new drones is it, really?

What happened to free markets?

Am I suggesting that the U.S. government’s actions are completely misguided? Not at all. Obviously, the People’s Republic of China is a leading adversary, with a vested interest in collecting any and all surveillance information, whether audio, visual, and/or otherwise. And ironically, effective May 1, 2026, China itself has banned all drone sales and rentals in Beijing, the capital, along with restrictions on the broader storage of drones and drone components within the city. So, for one of its leading companies to complain about sales and usage restrictions elsewhere in the world is a “bit” of a “doth protest too much” situation, methinks.

That said, as I’ve mentioned previously, DJI’s longstanding greater-than-90% market share in consumer drones also can’t (or at least shouldn’t) be overlooked, as it reflects both the sizeable installed base and ongoing customer preference. Notable, as well, is the fact that other drone companies such as Skydio have already withdrawn from the broad market, focusing solely on enterprise opportunities going forward.

So, even if the U.S. government had hoped to use a DJI ban to boost the fortunes of alternative domestic suppliers, that supply doesn’t currently exist. And regarding the security angle, while I get it (though I’d still welcome indisputable proof of it) for gear that can directly live-stream audio and images using DJI’s own applications, I remain baffled as to why such bans extend to devices that aren’t directly Internet-connectable, especially those (such as gimbals) with no native multimedia data-capture capabilities.

Anyway, it’s not just consumers like me that’ll be affected. Here, off the top of my head and in no particular order save for how they streamed out of my noggin, are examples of business and civic entities already making notable use of drones, with broader near-term expansion planned.

• Restaurants and chains
• Food-and-other delivery services
• Law enforcement, including border patrol
• Fire spotters and fighters
• Ranchers and farmers
• Medical facilities
• Utility companies
• Filmmakers
• Researchers of all sorts
• Musicians and other performers

To wit, here’s just one recent case study from just a few miles to the east of me:

Are many of them currently using DJI-branded equipment? You bet. Can at least some of them switch to non-DJI drones in the future, assuming sufficient supply exists? I suppose. But at what cost? Not insignificant. And can all, or even many, afford the incremental investment? Doubtful.

Thereby likely explaining, at least in part, why what was initially seen as a planned full-stop ban ended up scaled back to a going-forward prohibition…but still…consider, for example, repair and replacement-parts availability impacts, along with aforementioned warranty-coverage issues.

Other conceptually similar, more recent actions by various U.S. government entities involve restrictions on routers and cellular hotspots, along with some (but not all) connected vehicles, solar inverters and robots of all sorts…but this writeup is already running long, so I’ll save those for another day. For now, I welcome reader perspectives in the comments on the issues I’ve raised here!

​India’s electric vehicle (EV) sector is expected to become one of the country’s largest employment generators by 2030, with the potential to create between 30 million and 40 million jobs over the next five years. The rapid expansion of the EV ecosystem is poised to create significant job opportunities in manufacturing (automotive and components, battery assembly and cells), software and IT, infrastructure development, and services for EVs towards sustainable mobility.

According to industry predictions, 10-15% of these jobs will be direct employment opportunities with roles including vehicle production, cell manufacturing, electronics and components, R&D, engineering, quality control and charging infrastructure deployment. The remaining 85-90% of jobs would be indirect across the broader EV ecosystem such as manufacturing components, supply chains, maintenance and repair, retail and finance, logistics, and recycling.

This predicted job creation is seen as a natural consequence of India’s rising investments in electric mobility, spurred by schemes like the PM E-DRIVE Scheme, the Production Linked Incentive (PLI) programmes for the automobile and advanced chemistry cell (ACC) battery sector, and the broader focus on domestic manufacturing under the Atmanirbhar Bharat initiative.

As a result, domestic and international manufacturers are increasing their production facilities and scaling up operations across the country.​ As India progressively transitions to clean mobility, the EV industry is all set to become one of the country’s most significant drivers of economic growth, technology advancement and creation of sustainable employment.

​The Indian Ministry of Defence issued a Request for Information (RFI) for 2,715 logistics drones to accelerate last-mile supply capabilities for soldiers deployed in high-altitude and remote areas like the Siachen Glacier, where transporting goods normally becomes difficult due to extreme weather conditions. The RFI intends to evaluate Indian capabilities in drone technology, production capacity and vendors’ ability to comply with the Army’s operational requirements.

If the procurement moves forward, it would be one of the Indian Army’s largest intended procurements in the logistics drone category and the drones could aid supply operations up to an altitude of 20,000 ft. The procurement is also expected to significantly support India’s expanding defence drone market. Consistent with the government’s Atmanirbhar Bharat (self reliance) policy, the Army has steadily relied on native technologies for surveillance, logistics, counter-drone technologies, and loitering munitions. The RFI is expected to attract a large number of drone manufacturers once the programme progresses to the next procurement stage.

Besides boosting operational performance, introducing logistics drones should reduce the pressure on helicopters, which are commonly used for supplying heavy lifts, but drones can execute missions at lower operational costs and reduce the risk of operating within a dangerous mountain environment.

The introduction of 2,715 logistics drones planned is yet another major step towards the Indian Army’​s ambition of revolutionising battlefield sustainment through unmanned systems. The programme is bound to enhance battle effectiveness in the most challenging military operations, boost the indigenous defence drone industry, and support India’s long-term self reliance in cutting edge military technologies.​

DigiKey, the global distribution leader of electronic components and automation products, is hosting a webinar with Shawn Hymel: “Train a balance bot with reinforcement learning,” scheduled for Thursday, Aug. 13, 2026, at 10 a.m. CDT. The free 90 minute virtual event will be a hands-on robotics and AI workshop that will teach attendees how to get started in the growing field of reinforcement learning (RL).

Reinforcement learning is a powerful domain within machine learning that teaches agents to make decisions by interacting with an environment and maximizing a reward signal. It can enable robots to learn complex behaviors like balancing, walking and recovering from falls entirely in simulation before ever touching real hardware.

During the workshop, Hymel will guide attendees through training a self-balancing robot using RL and deploying it on real hardware. Attendees will learn to:

• Import a 3D model of the M5Stack Bala-C into the MuJoCo physics simulator
• Train a neural network policy using a multi-phase PPO curriculum
• Deploy the trained actor network to an ESP32 microcontroller using Arduino
• Understand the sim-to-real pipeline, a foundational skill for applying modern AI
  techniques to physical robotics

“Reinforcement learning has quickly become an exciting tool across a wide range of modern applications,” said David Sandys, senior director of technical enablement & engagement for DigiKey. “It’s a complex and growing field, and knowing where to begin can be tricky. That’s why we’re thankful to partner with Shawn Hymel to help bring this educational workshop to our customers and community to share how to get started, and why it’s beneficial to gain this knowledge.”

“Almost every major robotics lab has turned to reinforcement learning to build robust, AI-powered control and decision-making for their robots, from quadrupeds to bipeds,” says Hymel, expert instructor and content creator. “However, RL remains hard to approach. Training a policy can take millions of simulation steps, and getting the reward function right is as much art as science. This webinar will help lower the barrier to entry for anyone who wants to build their own robots with RL.”

Anyone who would like to follow along with the webinar is encouraged to have either the M5Stack Bala-C Balance Bot or the M5Stack Bala2 Fire Self-Balancing Robot. If you can’t attend the live webinar, you’re still encouraged to register, and the recording will be sent to all registrants following the event. Everyone is welcome to register for free.

DigiKey has also debuted the first of a six-part educational YouTube series in partnership with Hymel, designed to help engineers, hobbyists and students get started with robotics and RL. The full series will walk viewers through training a robot using modern RL techniques, from simulation to hardware deployment. By the end of the series, viewers will have a working remote-controlled balance bot that learned its own control policy, entirely through trial and error in simulation. Viewers can also follow the full write-up of the tutorial on DigiKey’s Maker.io site.

This webinar and video series furthers DigiKey’s commitment to providing helpful resources and education for engineers, designers, makers and students. For more information about other resources and educational content, please visit DigiKey.com.
