The LM73100 is a cute ideal diode 😎🔋

As we pass through the cycle of life, some may seek ideal happiness - we can't help with that quest. But if you're looking for an ideal diode, we found a pretty sweet one on last week's The Great Search: 🔍 https://blog.adafruit.com/2025/05/05/the-great-search-power-monitor-with-2-inputs-thegreatsearch-digikey-digikey-adafruit-2/

The LM73100 🔗 https://www.digikey.com/en/products/detail/texas-instruments/LM73100RPWR/13627234 … can handle up to 5A and 23V - perfect for applications like solar panels where you want to avoid losing 0.5W+ to a Schottky diode.

Here's a quick breakout we designed for it: By default, it works just like a diode, with VIN and VOUT terminal blocks. But if you want to access more features, there's a 0.1" breakout. The IMON pin gives a voltage from 0-1.5V as current goes from 0-5A. Plus, it has options for overvoltage and undervoltage lockout and a power good output. ☀️🔋

"It may sound surprising, but when times are tough and there is no other food available, some soil bacteria can consume traces of hydrogen in the air as an energy source.

In fact, bacteria remove a staggering 70 million tonnes of hydrogen yearly from the atmosphere, a process that literally shapes the composition of the air we breathe.

We have isolated an enzyme that enables some bacteria to consume hydrogen and extract energy from it, and found it can produce an electric current directly when exposed to even minute amounts of hydrogen.

As we report in a new paper in Nature, the enzyme may have considerable potential to power small, sustainable air-powered devices in future.

Bacterial genes contain the secret for turning air into electricity

Prompted by this discovery, we analysed the genetic code of a soil bacterium called Mycobacterium smegmatis, which consumes hydrogen from air.

Written into these genes is the blueprint for producing the molecular machine responsible for consuming hydrogen and converting it into energy for the bacterium. This machine is an enzyme called a “hydrogenase”, and we named it Huc for short.

Hydrogen is the simplest molecule, made of two positively charged protons held together by a bond formed by two negatively charged electrons. Huc breaks this bond, the protons part ways, and the electrons are released...

The molecular blueprint for extracting hydrogen from air

With Huc isolated, we set about studying it in earnest, to discover what exactly the enzyme is capable of. How can it turn the hydrogen in the air into a sustainable source of electricity?

Remarkably, we found that even when isolated from the bacteria, Huc can consume hydrogen at concentrations far lower even than the tiny traces in the air. In fact, Huc still consumed whiffs of hydrogen too faint to be detected by our gas chromatograph, a highly sensitive instrument we use to measure gas concentrations...

Enzymes could use air to power the devices of tomorrow

It’s early days for this research, and several technical challenges need to be overcome to realise the potential of Huc.

For one thing, we will need to significantly increase the scale of Huc production. In the lab we produce Huc in milligram quantities, but we want to scale this up to grams and ultimately kilograms.

However, our work demonstrates that Huc functions like a “natural battery” producing a sustained electrical current from air or added hydrogen.

As a result, Huc has considerable potential in developing small, sustainable air-powered devices as an alternative to solar power.

The amount of energy provided by hydrogen in the air would be small, but likely sufficient to power a biometric monitor, clock, LED globe or simple computer. With more hydrogen, Huc produces more electricity and could potentially power larger devices.

Another application would be the development of Huc-based bioelectric sensors for detecting hydrogen, which could be incredibly sensitive. Huc could be invaluable for detecting leaks in the infrastructure of our burgeoning hydrogen economy or in a medical setting.

In short, this research shows how a fundamental discovery about how bacteria in soils feed themselves can lead to a reimagining of the chemistry of life. Ultimately it may also lead to the development of technologies for the future."

American Politics — What Happened Today That You Should Know

Wednesday, June 18, 2025

Trump is checked out while his administration is seizing control of everything that moves.

While he saluted flagpoles and watched construction crews, his appointees weaponized student visas, Medicaid databases, and federal contracts into surveillance and deportation tools. They're moving with 54-minute deadlines and contempt-of-court defiance to capture every institution they can reach.

Iran is pushing us toward the biggest war in decades, but Trump's too distracted calling Fed chairs "stupid" to notice his own government is both executing authoritarian control and falling apart simultaneously.

The system is fighting back through courts, walkouts, and protest art, but his underlings don't need him paying attention to finish the job. That's why you need to pay attention to them.

Trump claims Iran proposed White House talks while threatening military strikes, but Tehran’s UN mission denies making any such proposal.

State Dept. contradicts Amb. Huckabee’s social media announcement of evacuation flights for Americans in Israel, saying it has no plans to assist departures.

Federal Reserve keeps rates steady despite Trump calling Powell “stupid” and demanding cuts to reduce government’s $1.2 trillion annual debt interest costs.

New data shows Medicare and Social Security stop paying full benefits in 8-9 years, earlier than projected, before accounting for Trump’s pending budget bill that would trigger additional Medicare cuts.

Justice Dept. plans to cut two-thirds of inspectors monitoring gun dealers for illegal sales as part of Trump administration effort to “defang and downsize” ATF.

Harvard cancer researcher Kseniia Petrova appears in court after months in custody for allegedly smuggling frog embryos as federal investigator admits he can’t define “biological materials” central to charges.

Senate Democrats walk out of Judiciary Committee hearing on Biden mental fitness as Durbin accuses Republicans of ignoring oversight of Trump administration’s military deployments and Sen. Padilla handcuffing.

FL Attorney General Uthmeier held in civil contempt for defying federal court order halting immigration law, must now file biweekly reports or face fines.

California senators demand Trump officials stop using Medicaid data for deportations after administration gave CMS 54-minute deadline to share millions of enrollees’ immigration status.

US resumes issuing student visas but requires all international applicants to make social media accounts public, warning private accounts may be suspicious.

Feds sue Kentucky Gov. Beshear over in-state tuition for undocumented immigrants living in KY, claiming it gives them preferential treatment over out-of-state U.S. citizens.

FL Board of Governors expected to approve three DeSantis appointees as university presidents after rejecting University of Florida’s choice Santa Ono as too “woke.”

DHS Secretary Noem requires personal approval for all contracts over $100k despite facing 5,100 annual reviews, prompting former acquisition chief to call policy “absolutely nuts.”

Independent National Academies report finds 30% of air traffic control facilities understaffed due to government shutdowns and hiring freezes, urges Congress to provide FAA resources to fix crisis.

Trump personally watches flagpole installation on White House lawn while Iran-Israel conflict escalates and questions mount about potential US military involvement.

Anatomy of a Dalek

A Dalek is primarily made from Dalekanium and polycarbide and is technically a cyborg. To understand how a Dalek is created, see How Do Daleks Become Daleks?

Some Daleks will have variations on the below, but these aspects of a Dalek's anatomy are broadly applicable to most.

The Dome (aka dome section, head section, head dome) is attached to the neck via a docking clamp.

Eyestalk (aka eyepiece, eye antenna, tele-eye, eye-stick, optical stalk, sensory antenna, eyeball unit). The eyestalk is attached to the dome via a lens attachment, sitting on a pivot in a cowl. The eye itself is known as an eyelens. The eyestalk is covered in multiple insulator discs to protect it from radiation.

Luminosity dischargers (aka headlamp, radiation valve, dome light, vocaliser light, sound disc). It's not quite known how or why the luminosity dischargers sync up with Dalek speech, but they could be energy compensators, translation units, safety valves to release excess energy, or just lights to indicate when a Dalek's speaking.

Neck (aka grating section, upper grating section). Attached to the weapons platform via another docking clamp, or 'catch'.

Neck rings support the neck grille.

Neck grille (aka audio receptor grill, sensor grille, sensor mesh, sensor grid louvres) cover the mutant Dalek within.

Weapons Platform (aka shoulder platform, shoulder section).

Slats (aka solar power collection slats, solar slats, solar cells, shoulder slats, armour slats, sensor plates) are effectively solar panels that absorb energy to power the Dalek.

Gunstick (aka radiation gun, gun-rod, ray-gun, exterminator, blast-gun, energy gun, Dalek neutraliser, neutraliser, beam distributor, Dalek beam gun, Dalek gun, ruby ray blaster). Sits on a balljoint, controlled by armament circuits. Can be set to non-lethal, causing temporary paralysis, but maximum settings can split atoms apart. Some Daleks deliberately reduce the power of their gunstick so that the beam burns away the central nervous system outside inwards, so victims die within 2-3 seconds in complete agony.

Manipulator arm (aka tactile arm, arm-stick). Usually sits on a balljoint. Attachments can be swapped out for various tools depending on the needs of the Dalek. Some attachments include the plunger, flamethrower, seismic detector, electrode unit, sieve, syringe, blow torch, cutting tool, another gunstick, or a claw, or basically anything they need.

Base Unit (aka travel unit). Contains the motive unit, the elevation unit, and thrusters.

Sense spheres (aka sensor globes, sensor arrays, bumps) can do pretty much whatever you want them to, including detecting emissions, monitoring the surrounding environment, and acting as self-destruct mechanisms. They can also function as sockets for cables and wires, and some say the sensor globes are capable of free flight, allowing them to provide remote battlefield intelligence.

Bumper (aka fender). Possibly containing proximal alert systems to detect other Daleks, but more likely just softening collisions.

Applications of Current Transformer Bases in Renewable Energy Systems

As the global focus shifts toward cleaner, more sustainable energy sources, the demand for reliable, efficient, and intelligent electrical infrastructure becomes increasingly vital.  One of the foundational components that enable safe and accurate energy monitoring and control in renewable energy systems is the current transformer base.  These critical components play a pivotal role in energy metering, system protection, and performance optimization across solar, wind, and hybrid renewable installations.

In this blog, we will explore the essential applications of current transformer bases in renewable energy systems, discuss their growing importance in India’s green energy landscape, and highlight why selecting the right current transformer base manufacturer in India matters for operational excellence.

Understanding the Role of a Current Transformer Base

A current transformer base acts as the support structure and housing for current transformers (CTs), which are instrumental in measuring alternating current (AC) in high-voltage environments.  CTs step down high currents to safer levels for metering and protection devices, making it easier to monitor and control energy flows in power systems.

In renewable energy systems—where the electricity generated often varies with environmental conditions—the role of CTs and their bases becomes even more critical.  They ensure:

Accurate current measurement

Organic compound boosts solar cell stretchability without sacrificing power

A solar cell developed by RIKEN physicists can be stretched without greatly affecting its ability to convert light into electricity. It is thus promising for powering the next generation of wearable electronics. Today's smart watches can monitor an impressive array of health metrics, while more-specialist wearable devices are being developed for specific medical applications. But such devices need to be recharged periodically. To eliminate this need, researchers are seeking to develop flexible, wearable solar cells. However, it is vital to ensure that the performance of these solar cells doesn't drop off when they are stretched by body movements during everyday life. "We're focusing on making very thin, flexible devices. But such devices don't have intrinsic stretchability," explains Kenjiro Fukuda of the RIKEN Center for Emergent Matter Science. "Rather, they're similar to plastic wrap used to wrap food—you can maybe stretch them by 1% or 2%, but 10% is impossible since they tear easily."

Good News - April 8-14

(Actually 8-12 due to irl obligations)

Like these weekly compilations? Support me on Ko-fi! Also, if you tip me on here or Ko-fi, at the end of the month I'll send you a link to all of the articles I found but didn't use each week - almost double the content! (I'm new to taking tips on here; if it doesn't show me your username or if you have DM's turned off, please send me a screenshot of your payment)

1. Interior Department Finalizes Action to Strengthen Endangered Species Act

“These revisions, which will increase efficiency by reducing the time and cost to develop and negotiate permit applications, will encourage more individuals and companies to engage in conservation benefit agreements and habitat conservation plans, generating greater conservation results overall.”

2. Young Puerto Ricans Restore Habitat Damaged by Hurricane While Launching Conservation Careers

“Corps members help restore the island’s environmental and cultural assets and volunteer in hard-hit local communities. They also gain valuable paid work experience and connections to possible future employers, something many young Puerto Ricans struggle to find.”

3. Australian-born cheetah released in Africa for the first time ever. Watch the heart-warming moment Edie is set free

““The Metapopulation Initiative will bring in appropriate males, probably two initially, to breed with Edie,” King says. “It’s those future cubs, and their cubs, that will ensure the legacy of spreading Edie’s genetics across the southern African metapopulation. And we will have also provided Edie – a wild animal, let’s not forget – with a chance of a life in the wild.””

4. Baby Bald Eagles Confirmed in 2 of 4 Nests in Will County Forest Preserves

“A pair of fuzzy eaglet heads were spotted popping up out of one of the nests this week, officials said. Two weeks ago, monitors noticed adult eagles feeding an unseen hatchling (or hatchlings) in a different nest.”

5. New Hope for Love for Japanese Children Needing Families

“The new system, established by a 2022 law, offers private childcare institutions financing to transform their business model into “Foster Care Support Centers” that recruit, train, select, and support foster parents, and assist the independence of children living in foster families. If a childcare institution becomes a Foster Care Support Center, the government will fund full-time staff members based on the number of foster households they cater to.”

6. Nexamp nabs $520M to build community solar across the US

“Nexamp, a community solar developer and project owner, has secured a whopping $520million to install solar arrays around the nation in one of the largest capital raises to date for this growing sector. Community solar gives renters, small businesses and organizations the chance to benefit from local solar power even if they can’t put panels on their own roofs.”

7. A natural touch for coastal defense: Hybrid solutions which combine nature with common “hard” coastal protection measures may offer more benefits in lower-risk areas

“Common “hard” coastal defenses, like concrete sea walls, might struggle to keep up with increasing climate risks. A new study shows that combining them with nature-based solutions could, in some contexts, create defenses which are better able to adapt.”

8. Rewilding program ships eggs around the world to restore Raja Ampat zebra sharks

“A survey estimated the zebra shark had a population of 20 spread throughout the Raja Ampat archipelago, making the animal functionally extinct in the region. […] Researchers hope to release 500 zebra sharks into the wild within 10 years in an effort to support a large, genetically diverse breeding population.”

9. Forest Loss Plummets in Brazil and Colombia

“New data reveals a decline in primary forest loss in Brazil and Colombia, highlighting the significant impact of environmental reforms in curbing deforestation. According to 2022-2023 data from the University of Maryland’s GLAD Lab and World Resource’s Institute (WRI), primary forests in Brazil experienced a 36 per cent decrease in deforestation under President Inácio Lula da Silva’s leadership, reaching its lowest level since 2015. Colombia nearly halved (by 49 per cent) its forest loss under the administration of President Gustavo Petro Urrego, who has prioritised rural and environmental reform.”

10. New Agreement Paves the Way for Ocelot Reintroduction on Private Lands

“With the safe harbor agreement in place, partners plan to begin developing a source stock of ocelots for reintroduction. Over the next year, they plan to construct an ocelot conservation facility in Kingsville to breed and raise ocelots. Producing the first offspring is expected to take a few years.”
