Surgery is hard, there is a reason why school is so long for the profession. Making the job easier and smoother for both patients and surgeons is valuable for all parties, which is why [Mayo Clinic] is now working on including 3D printing into its more regular medicine pipeline.

Prepping for surgery often requires examining CT scans of patients to figure out, well, what they’re even going to be doing. Every body is different, and complex surgical procedures require checking to see where certain organs or features are located. This can be made much easier with a physical model of where the bones, organs, or nerves are specifically located in a patient. While this isn’t true in every case of treatment, there are even cancerous cases where custom equipment can be used to decrease side effects, such as mini-beam collimator adapters.

What if you could use the same pipeline to print what was lost from certain procedures? In a mastectomy, the breast tissue is removed, which can cause negative attention from curious gazes. So why not 3D print a custom breast? Cases like these are generally considered poor commercial investments from industry, but are relatively easy for an existing medical facility to add to treatment.

[Mayo Clinic] is far from the first to consider 3D printing in the medical setting, but seeing the technology see actual applied use rather than future seeking is exciting. Medical hacking is always exciting, and if you want to see more examples, keep sure to check out this commercially available simulator (with some free models).

If you want to know when the train is coming, you could pull up a webpage on your phone, or walk all the way to the station to look at the displays there. Or, like [eastfamilyreddish], you could build a neat little train info display to decorate your desktop instead.

The build is based on the work of [gadec-uk]—who developed a train information display some time ago. It’s based around an ESP32 D1 Mini, paired with a 256 x 64 OLED screen to display relevant train information. It accesses a National Rail API for train status information—known as the Darwin LDBWS (Live Departure Board Webservice). Configuration is via a web GUI hosted by the ESP32 itself.

[eastfamilyreddish] took the concept further by adapting this hardware into a more pleasing form. The ESP32 and OLED screen are built into a neat little hanging sign setup that apes one you might expect to see at a real railway station. You might expect that 3D printing was involved, but instead, this was achieved with lasercut parts and resin casting to create something with a beautiful finish. They even went so far as to include a wireless phone charging module in the base, making the device extra useful to really earn its place on the desktop.

The fact is, around these parts we love both trains and the displays you find around them. If you’ve got a railway-adjacent project, or you’ve just built your own awesome railway, don’t hesitate to let us know on the tipsline!

Sometimes you need to know what temperature something is, but you don’t quite want to touch it. At times like these, you might want a temp gun on hand to get a good reading, like the one [Arnov Sharma] built.

The build is a relatively simple one, and is based around an Waveshare ESP32 C6 development module that comes with a small LCD screen out of the box. The microcontroller is set up to read an MLX90614 infrared temperature sensor. This device picks up the infrared energy that is emitted by objects relative to their temperature. The sensor has a great range—from -70 C to 380 C. The readouts from this sensor are then displayed on the screen. Battery power is from a small 600 mAh LiPo cell, which is managed by a IP5306 charge module.

It’s worth noting that these infrared temperature sensors aren’t infallible devices. The temperature they perceive is based on certain assumptions about factors like an objects emissivity. Thus, they don’t always give accurate readings on metallic or shiny objects, for example. It’s also important to understand the sensor’s field of view. Despite many commercial versions featuring a laser pointer for aiming, many of these infrared temperature sensors tend to average their reading over a small spot that gets larger the farther away they are from the object being measured.

Tools like portable temp guns are pretty cheap, but sometimes it’s just fun to build your own. Plus, you usually learn something along the way. Video after the break.

Il Roskomnadzor della Federazione Russa ha annunciato che continua a imporre restrizioni sistematiche all’app di messaggistica WhatsApp a causa di violazioni della legge russa. Secondo l’agenzia, il servizio viene utilizzato per organizzare e compiere attacchi terroristici in Russia, reclutare terroristi e commettere frodi e altri reati contro i cittadini.

Il rapporto afferma che WhatsApp non rispetta i requisiti volti a prevenire e combattere la criminalità in Russia. L’autorità di regolamentazione ha sottolineato che, in tali circostanze, le restrizioni al servizio di messaggistica saranno estese e, se continuerà a non rispettare la legge russa, il servizio potrebbe essere completamente bloccato nel Paese.

Il Roskomnadzor ha ricordato agli utenti che il graduale deterioramento delle chiamate vocali e video di WhatsApp è iniziato ad agosto. Le restrizioni vengono introdotte gradualmente per consentire agli utenti di passare ad altri servizi. L’agenzia raccomanda di scegliere app di messaggistica nazionali e afferma esplicitamente che, se la situazione attuale dovesse persistere, il blocco potrebbe diventare la misura definitiva.

Andrey Svintsov, vicepresidente della Commissione per la politica dell’informazione, le tecnologie dell’informazione e le comunicazioni della Duma di Stato, ha dichiarato a NEWS.ru che prevede che WhatsApp verrà completamente bloccato in Russia nei prossimi mesi.

Stima che ciò potrebbe accadere entro quattro-sei mesi. Ritiene che questo non rappresenterà un problema critico per gli utenti, osservando che Viber, un tempo popolare, è di fatto scomparso dalla scena pubblica dopo il suo fallimento, e suggerisce che una situazione simile potrebbe verificarsi anche per WhatsApp.

Svintsov ha sottolineato che, a suo avviso, il blocco è dovuto al rifiuto dei creatori del servizio di messaggistica di collaborare con le autorità russe.

Ha sottolineato che WhatsApp è di proprietà di Meta (considerata un’organizzazione estremista in Russia, le cui attività sono vietate) e che i dati dei cittadini russi sono archiviati all’estero. Il deputato afferma che il servizio trasmette informazioni personali, aziendali e talvolta critiche, e sostiene che questi dati vengano utilizzati dalle agenzie di intelligence occidentali, anche nel contesto della lotta alla Russia.

Alla luce di ciò, conclude che, a suo avviso, “saranno necessarie ulteriori restrizioni al servizio di messaggistica”.

[shiura] had a problem — they wanted a nice high-quality audio output for their computer, but they didn’t fancy any of the DACs that were readily available on the market. They specifically wanted one that was affordable, capable, and included a graphic equalizer so they could simply hook it up to a regular amplifier and dial in the perfect sound. When they couldn’t find such a device, they decided to build their own.

The build is based around a Raspberry Pi Pico, chosen for its feature set that makes it easy to configure as a USB audio device. It’s paired with a Waveshare Pico Audio module, which is based on the PCM5101A stereo DAC and slots neatly on top of the microcontroller board. An SPI-controlled LCD screen was also fitted in order to display the graphic equalizer interface that [shiura] whipped up. The project write-up explains the code required to implement the equalizer in detail. A four-channel equalizer was possible on the original Pi Pico (RP2040), while upgrading to a more powerful Pi Pico 2 (RP2350) allowed implementing eight channels in total.

If you’re looking to build a digital audio system with the ability to do some equalization to suit your listening room, this might be a project of interest to you. We’ve featured other projects in this realm before, too.

The EU Council’s current push to make Chat Control 1.0 (Regulation (EU) 2021/1232) permanent is legally and ethically reckless. The Commission’s own 2025 evaluation report admits to a total failure in data collection, an inability to link mass surveillance to actual convictions, and significant error rates in detection technologies. To permanently enshrine a derogation of fundamental rights based on a report that explicitly states “available data are insufficient” to judge proportionality is a violation of EU lawmaking principles.

Detailed Critique

1. The “Argument from Ignorance” on Proportionality

The Report: In Section 3 (Conclusions), the Commission states that “the available data are insufficient to provide a definitive answer” regarding the proportionality of the Regulation. Yet, in the very same paragraph, it concludes: “there are no indications that the derogation is not proportionate.”
The Critique: This is a logical fallacy. The Commission is arguing that because their data is too fragmented to prove the law is bad, it must be good. You cannot permanently suspend the fundamental right to privacy (Article 7, Charter of Fundamental Rights) based on an absence of data. The burden of proof lies with the legislator to demonstrate necessity and efficacy, which this report fails to do.

2. The Broken Link Between Surveillance and Convictions

The Report: Section 2.2.3 explicitly admits: “It is not currently possible… to establish a clear link between these convictions and the reports submitted by providers.” Furthermore, major Member States like Germany and Spain failed to provide usable data on convictions linked to this Regulation.
The Critique: As noted in my blogpost on the previous evaluation, there is no evidence that the mass scanning of private messages contributes significantly to convicting abusers. If millions of private messages are scanned and hundreds of thousands of reports are generated (708,894 in 2024), but the Commission cannot point to a specific number of resulting convictions, the system is a dragnet that violates privacy without a proven benefit to child safety. The system generates “noise” for law enforcement rather than actionable intelligence.

3. High Error Rates and “Black Box” Algorithms

The Report:

• Microsoft (Section 2.1.6) reported that its data was “insufficient to calculate an error rate.”
• Yubo reported error rates for detecting new CSAM/grooming of 20% in 2023 and 13% in 2024.
• The report notes that “human review is not factored into the statistics,” meaning the raw algorithmic intrusion is even less accurate than presented.

The Critique: Making this regulation permanent endorses the use of technology that is admittedly flawed. A 13-20% error rate in flagging “grooming” or new CSAM means thousands of innocent users are flagged, their private communications viewed by corporate moderators, and potentially reported to police erroneously. The fact that a giant like Microsoft cannot even calculate its error rate proves that Big Tech is operating without accountability or transparency. According to the German Police and former EU Commissioner Johansson the actual error rate is far higher (50-75%).

4. Chaos in Data and Lack of EU Control

The Report: The Commission admits that providers “did not use the standard form for reporting” (Section 1) and that Member States provided “fragmented and incomplete” data. The disparity between NCMEC reports sent to Member States vs. reports acknowledged by Member States is massive (e.g., France received 150k reports from NCMEC but has incomplete processing data).
The Critique: The EU cannot effectively oversee this surveillance. If, after three years, the Commission cannot force providers to use a standard reporting form or get Member States to track basic statistics, the Regulation is dysfunctional. Making a dysfunctional temporary fix permanent is poor governance. It cements a system where US tech giants (Google, Meta, Microsoft) act as private police forces with no standardized oversight.

5. Obsolescence via Encryption

The Report: The report notes a 30% drop in reports concerning the EU in 2024, attributed largely to interpersonal messaging services moving to end-to-end encryption (E2EE) (Section 2.2.1).
The Critique: The Regulation is already obsolete. As noted in the previous commentary, as platforms move to E2EE (like Meta), voluntary scanning becomes impossible without breaking encryption (client-side scanning). The drop in reports proves that voluntary scanning is a dying model. Making this Regulation permanent is a desperate attempt to cling to a failing approach rather than investing in targeted investigations and “safety by design” that respects encryption.

6. Failure to Assess Privacy Intrusion

The Report: The conclusion states: “No information was submitted by the providers on whether the technologies were deployed… in the least privacy-intrusive way.”
The Critique: The Regulation requires that the derogation be used only when necessary and in the least intrusive manner. The Commission admits it has no information on whether this legal requirement is being met. To extend a law permanently when the primary safeguard (minimization of privacy intrusion) is not being monitored is a dereliction of duty.

Conclusion

The Council looks to permanently legalize a regime of mass surveillance where:

1. The technology has double-digit error rates (Yubo).
2. The efficacy (convictions) is unproven.
3. The oversight (data collection) is broken.
4. The targets (encrypted chats) are increasingly immune to it.

This confirms the fears raised in the previous evaluation: this is performative security that sacrifices the privacy of all citizens for a system that the Commission admits it cannot properly measure or validate.
