2025 One Hertz Challenge: An Arduino-Based Heart Rate Sensor
How fast does your heart beat? It’s a tough question to answer, because our heart rate changes all the time depending on what we’re doing and how our body is behaving. However, [Ludwin] noted that resting heart rates often settle somewhere near 60 bpm on average. Thus, they entered a heart rate sensor to our 2025 One Hertz Challenge!
The build is based around a Wemos D1 mini, a ESP8266 development board. It’s hooked up to a MAX30102 heart beat sensor, which uses pulse oximetry to determine heart rate with a photosensor and LEDs. Basically, it’s possible to determine the oxygenation of blood by measuring its absorbance of red and infrared wavelengths, usually done by passing light through a finger. Meanwhile, by measuring the change in absorption of light in the finger as blood flows with the beat of the heat, it’s also possible to measure a person’s pulse rate.
The Wemos D1 takes the reading from the MAX30102, and displays it on a small OLED display. It reports heart rate in both beats per minute and in Hertz. if you can happen to get your heartrate to exactly 60 beats per minute, it will be beating at precisely 1 Hertz. Perhaps, then, it’s the person using Ludwin’s build that is actually eligible for the One Hertz Challenge, since they’re the one doing something once per second?
In any case, it shows just how easy it is to pick up biometric data these days. You only need a capable microcontroller and some off-the-shelf sensors, and you’re up and running.

Gentle Processing Makes Better Rubber That Cracks Less
Rubber! It starts out as a goopy material harvested from special trees, and is then processed into a resilient, flexible material used for innumerable important purposes. In the vast majority of applications, rubber is prized for its elasticity, which eventually goes away with repeated stress cycles, exposure to heat, and time. When a rubber part starts to show cracks, it’s generally time to replace it.
Researchers at Harvard have now found a way to potentially increase rubber’s ability to withstand cracking. The paper, published in Nature Sustainability, outlines how the material can be treated to provide far greater durability and toughness.
Big Flex
Note the differences between a short-chain crosslinked structure, and the longer-chain tanglemer structure with far less crosslinks. The latter is far better at resisting crack formation, since the longer chain can deconcentrate stress over a longer distance, allowing far greater stretch before failure. Credit: research paper
The traditional method of producing rubber products starts with harvesting the natural rubber latex from various types of rubber tree. The trees are tapped to release their milky sap, which is then dried, processed with additives, and shaped into the desired form before heating with sulfur compounds to vulcanize the material. It’s this last step that is key to producing the finished product we know as rubber, as used in products like tires, erasers, and o-rings. The vulcanization process causes the creation of short crosslinked polymer chains in the rubber, which determine the final properties and behavior of the material.
Harvard researchers modified the traditional rubber production process to be gentler. Typical rubber production includes heavy-handed mixing and extruding steps which tend to “masticate” the polymers in the material, turning them into shorter chains. The new, gentler process better preserves the long polymer chains initially present in the raw rubber. When put through the final stages of processing, these longer chains form into a structure referred to as a “tanglemer”, where the tangles of long polymer chains actually outnumber the sparse number of crosslinks between the chains in the structure.The gentler production method involves drying the latex and additive mixture at room temperature to form a film, before hot-pressing it to form the final tanglemer structure. This process isn’t practical for producing large, thick parts. Credit: research paper
This tanglemer structure is much better at resisting crack formation. “At a crack tip in the tanglemer, stress deconcentrates over a long polymer strand between neighbouring crosslinks,” notes the research paper. “The entanglements function as slip links and do not impede stress deconcentration, thus decoupling modulus and fatigue threshold.” Plus, these long, tangled polymer chains are just generally better at spreading out stress in the material than the shorter crosslinked chains found in traditional vulcanized rubber. With the stress more evenly distributed, the rubber is less likely to crack or fail in any given location. The material is thus far tougher, more durable, and more flexible. These properties hold up even over repeated loading cycles.
youtube.com/embed/UvGIVUFnsjg?…
Overall, the researchers found the material to be four times better at resisting crack growth during repeated stretch cycles. It also proved to be ten times tougher than traditional rubber. However, the new gentler processing method is fussy, and cannot outperform traditional rubber processing in all regards. After all, there’s a reason things are done the way they are in industry. Most notably, it relies on a lot of water evaporation, and it’s not currently viable for thick-wall parts like tires, for example. For thinner rubber parts, though, the mechanical advantages are all there—and this method could prove useful.
Ultimately, don’t expect to see new this ultra-rubber revolutionizing the tire market or glove manufacturing overnight. However, the research highlights an important fact—rubber can be made with significantly improved properties if the longer polymer chains can be preserved during processing, and tangled instead of excessively cross-linked. There may be more fruitful ground to explore to find other ways in which we can improve rubber by giving it a better, more resilient structure.
Droni in missione potranno decidere in modo autonomo quali uomini uccidere?
Sembra che gli Stati Uniti abbiano già seriamente preso in considerazione il concetto di guerra autonoma. Il jet da combattimento autonomo della DARPA , risulta in grado di combattere senza pilota, non è più considerato una svolta: l’agenzia è passata alla fase successiva di sviluppo, con l’obiettivo di creare sistemi in grado di controllare un gruppo di jet da combattimento in missioni congiunte oltre il raggio visivo.
Il nuovo programma della DARPA, Artificial Intelligence Reinforcements (AIR), si basa sul progetto Air Combat Evolution (ACE) , che ha messo a confronto F-16 dotati di intelligenza artificiale con velivoli con equipaggio in un addestramento “dogfight”. L’obiettivo è aumentare l’autonomia fino al punto in cui tali velivoli possano operare in formazione, coordinandosi su lunghe distanze e in ambienti di combattimento complessi. Il programma fa parte di una più ampia militarizzazione dell’intelligenza artificiale che sta sollevando preoccupazioni sulla sua sicurezza.
Sebbene AIR sia stato avviato più tardi di ACE, il concetto in sé non è nuovo: la prima domanda per il programma è stata pubblicata nel 2022. Questa settimana, la DARPA ha assegnato silenziosamente a Systems & Technology Research (STR) un contratto da 11,3 milioni di dollari nell’ambito della cosiddetta “Opzione Uno“. Come ha spiegato l’agenzia, questa è già la seconda delle due fasi previste del programma, il che indica che il progetto sta procedendo.
All’inizio di AIR, il programma coinvolgeva sei appaltatori, ma nella seconda fase il numero è stato ridotto a quattro. STR è responsabile di una delle due aree tecniche chiave: lo sviluppo di algoritmi che consentiranno l’esecuzione distribuita e autonoma di missioni tattiche in tempo reale in ambienti incerti, in rapida evoluzione e complessi. La seconda area prevede la creazione di modelli rapidi e accurati in grado di tenere conto dell’incertezza e di migliorare automaticamente con l’accumulo di dati.
Secondo la documentazione iniziale, l’AIR dovrebbe utilizzare sistemi di sensori, sistemi di guerra elettronica e armi esistenti. Le fasi di test includeranno simulazioni, quindi test con un essere umano nel circuito di controllo e infine test su un vero velivolo da combattimento senza pilota. Sviluppi simili sono già stati dimostrati: l’esercito statunitense ha creato un sistema robotico in grado di abbattere autonomamente i droni.
Oltre a STR, al progetto hanno partecipato anche Lockheed Martin e BAE Systems , ma la DARPA non ha ancora reso noto chi sarà incluso esattamente nella seconda fase: la selezione dei partecipanti è ancora in corso. I dettagli del lavoro nella prima e nella seconda fase rimangono riservati, ma è noto che la prossima fase durerà circa 30 mesi e coprirà la parte restante del programma.
La questione di quando i piloti saranno effettivamente costretti a cedere il passo all’intelligenza artificiale rimane aperta. E mentre gli sviluppatori stanno testando l’autonomia tattica, i critici non escludono scenari più inaspettati, fino al punto che un giorno un jet da combattimento autonomo decida di abbandonare una missione di combattimento. Gli esperti avvertono che la diffusione dell’IA militare potrebbe rendere il mondo meno sicuro , poiché l’IA commette errori e le conseguenze possono essere fatali . La comunità internazionale sta cercando di sviluppare un patto globale contro l’IA militare .

Why Lorde’s Clear CD has so Many Playback Issues
Despite the regularly proclaimed death of physical media, new audio albums are still being published on CD and vinyl. There’s something particularly interesting about Lorde’s new album Virgin however — the CD is a completely clear disc. Unfortunately there have been many reports of folks struggling to get the unique disc to actually play, and some sharp-eyed commentators have noted that the CD doesn’t claim to be Red Book compliant by the absence of the Compact CD logo.The clear Lorde audio CD in all its clear glory. (Credit: Adrian’s Digital Basement, YouTube)
To see what CD players see, [Adrian] of Adrian’s Digital Basement got out some tools and multiple CD players to dig into the issue. These players range from a 2003 Samsung, a 1987 NEC, and a cheap portable Coby player. But as all audio CDs are supposed to adhere to the Red Book standard, a 2025 CD should play just as happily on a 1980s CD player as vice versa.
The first step in testing was to identify the laser pickup (RF) signal test point on the PCB of each respective player. With this hooked up to a capable oscilloscope, you can begin to see the eye pattern forming. In addition to being useful with tuning the CD player, it’s also an indication of the signal quality that the rest of the CD player has to work with. Incidentally, this is also a factor when it comes to CD-R compatibility.
While the NEC player was happy with regular and CD-R discs, its laser pickup failed to get any solid signal off the clear Lorde disc. With the much newer Samsung player (see top image), the clear CD does play, but as the oscilloscope shot shows, it only barely gets a usable signal from the pickup. Likewise, the very generic Coby player also plays the audio CD, which indicates that any somewhat modern CD player with its generally much stronger laser and automatic gain control ought to be able to play it.
That said, it seems that very little of the laser’s light actually makes it back to the pickup’s sensor, which means that the gain gets probably cranked up to 11, and with that its remaining lifespan will be significantly shortened. Ergo it’s probably best to just burn that CD-R copy of the album and listen to that instead.

La gioia e la frustrazione di non essere più su Facebook
Io non desisto, anche rinfrancato dal fatto che l'affidabilità di Meta è sempre più in declino.
Mia moglie aveva disattivato il suo account Facebook anni fa e da qualche settimana aveva notato riapparire notifiche via mail. Chiaramente il suo account era stato hackerato.
Per settimane abbiamo provato a riprenderne il controllo e solo oggi ci siamo riusciti. Ore e ore perse dietro questi incompetenti.
In pratica mia moglie ogni 5 giorni, oltre alle usuali notifiche, riceveva un messaggio con un codice numerico per recuperare la password. Questo probabilmente era l'hacker che le impediva in questo modo di attivare la funzione di recupero della password. Infatti quando andava per attivarla, le diceva "Sembra che tu stia usando in modo errato questa funzione andando troppo velocemente. Ti è stato temporaneamente impedito di usarla.". Ma la cosa assurda è che esiste anche un link di Facebook per segnalare che il proprio account è stato hackerato ed utilizzandolo si riceveva la stessa risposta "Sembra che tu stia usando in modo errato questa funzione...", il che è completamente assurdo perché è proprio quello che gli hacker desiderano per impedire che qualcuno possa recuperare il proprio account!
Il tentativo che finalmente è andato in porto è stato quello di cercare di creare un account con la stessa e-mail e nome e a quel punto la funzione di recupero della password con l'invio di un codice si è attivata.
Ora il problema sarà riuscire ad entrare (per capire cosa ha fatto l'hacker) senza inchinarsi a 1) pagare dei soldi per non avere la pubblicità o 2) accettare che i propri dati personali vengano usati per pubblicità personalizzata. Ci siamo quasi e poi anche questo account verrà eliminato!

Pirate Candidate Announcement: Blase Henry for AZ’s 17th Legislative District
The United States Pirate Party is excited to announce our first of many candidates for the 2026 election cycle: AZPP Captain Blase Henry shall be running for Arizona’s 17th Legislative District!
Blase has been a rising star within the ranks of the United States Pirate Party, and with this announcement, he is officially the first Pirate we will be backing during the 2026 elections.
If elected, future State Rep. Henry has laid out to us some of the bills he plans on introducing, including but not limited to:
– A digital Bill of Rights for Arizona
– A bill banning ID requirement/age verification laws on the internet, AI or otherwise
– A bill similar to the “Stop Killing Games” initiative of Europe, aiming to protect video game consumers and players
– A bill that prevents internet service providers from sharing your data without your consent and make it so police need a warrant for your data
We are excited to share what will be the first of many Pirate candidates. Some candidates will appear on the ballot as independents, some as members of major parties and some, if they are so fortunate, will have “Pirate” next to their name on the ballot. No matter what it says next to their name on the ballot, we will throw our support behind our Pirate candidates.
NOTE: the US Pirate Party recently endorsed the gubernatorial campaign of Timothy Grady for Ohio. Timothy Grady is an independent candidate but is not officially a Pirate Party candidate. Blase Henry is the first official candidate announced from the US Pirate Party.
To quote Blase Henry himself: “Let’s Hoist the Colours and Join the Pirate Revolution! For if Buying isn’t Ownership, then Piracy isn’t Theft!”
You can visit his campaign website here, or if you’re an AZ resident, you can help get Blase on the ballot here.
