Высокопоставленные европейские чиновники были в шоке от встречи делегаций ЕС и США по Украине, а один из них назвал ее «тошнотворной»

Переговоры состоялись 21 ноября в резиденции поверенной в делах США на Украине Джули Дэвис в Киеве.

Американская делегация во главе с министром армии Дрисколлом провела встречу с европейскими чиновниками — Financial Times

«Украина находится в очень плохом положении..., то, что предлагается, — это лучшее, на что она может рассчитывать»,
— приводит издание слова Дрисколла.

Пишуть, що Лукашенко помилував 31 українця і їх повернуть додому.

Рішення прийняли нібито "на прохання української сторони" та "з метою створення умов для врегулювання збройного конфлікту" в Україні.

Трамп вважає, що Зеленський блефує щодо мирних перемов і готовий тиснути на нього, – пише Times.

Видання зазначає, що президент США так і не змінив своєї позиції після зустрічі в Овальному кабінеті у лютому.

Assistive Radio Tells You What You Can’t See

We think of radios as audio devices, but for people who are visually impaired, it can be difficult to tell which channel you are listening to at any given time. [Sncarter] has a family member with vision impairment and built a radio to help her. Unfortunately, it was difficult to replicate, so he decided to try again. The result is an FM radio that provides audible status notifications about power and frequency. Check it out in the video below.

This isn’t just some hacked-up commercial radio, but a ground-up design that uses a TEA5767 with an ATMega328 for control. There is an LCD for when someone else might use the radio and an audio amplifier. He built the prototype on a breadboard, but moved the finished product to a PCB.

It isn’t just the electronics and the sound that are assistive. The case has raised bosses to help the user find things like the switch and rotary encoder. The Arduino can speak frequency announcements, although the quality of the voice is something he wants to tackle in the next revision.

These radios on a chip give you many design options. These same ideas can be useful for audiobook players, too.

DIY TENS Machine is a Pain-Relief PCB

Transcutaneous Electrical Nerve Stimulation (TENS) is one of those things that sounds like it must be woo when you first hear of it. “A trickle of current that can deal with chronic pain better than the pills we’ve been using for decades? Yeah, and what chakras do you hook this doo-hickie up to?” It seems too good to be true, but in fact it’s a well-supported therapy that has become part of scientific medicine. There are no crystals needed, and you’re applying electrodes to the effected area, not your chakras. Like all medical devices, it can be expensive if you have to buy the machine out-of-pocket… but it is just a trickle of current. [Leon Hillmann] shows us its well within the range of hackability, so why not DIY?

[Leon]’s TENS machine is specifically designed to help a relative with hand problems, so breaks out electrodes for each finger, with one on the palm serving as a common ground. This type of TENS is “monophasic”– that is, DC, which is easier than balancing current flowing in two directions through quivering flesh. The direct current is provided at 32 V to the digit electrodes, safely kept to a constant amperage with a transistor-based current limiting circuit. The common ground in the palm is pulsed at a rate set by an ATmega32U4 and thus controllable: 14 Hz is given as an example.

Obviously if you want to reproduce this work you’re doing it at your own risk and need to consult with relevant medical professionals (blah blah blah, caveat gluteus maximus) but this particular sort of medical device is a good fit for the average hacker. Aside from prosthetics, we haven’t seen that much serious medical hacking since the pandemic. Still, like with synthesizing medical drugs, this is the kind of thing you probably don’t want to vibe code.

Building an Acoustic Radiometer

A Crookes radiometer, despite what many explanations claim, does not work because of radiation pressure. When light strikes the vanes inside the near-vacuum chamber, it heats the vanes, which then impart some extra energy to gas molecules bouncing off of them, causing the vanes to be pushed in the opposite direction. On the other hand, however, it is possible to build a radiometer that spins because of radiation pressure differences, but it’s easier to use acoustic radiation than light.

[Ben Krasnow] built two sets of vanes out of laser-cut aluminium with sound-absorbing foam attached to one side, and mounted the vanes around a jewel bearing taken from an analog voltmeter. He positioned the rotor above four speakers in an acoustically well-sealed chamber, then played 130-decibel white noise on the speakers. The aluminium side of the vanes, which reflected more sound, experienced more pressure than the foam side, causing them to spin. [Ben] tested both sets of vanes, which had the foam mounted on opposite sides, and they spun in opposite directions, which suggests that the pressure difference really was causing them to spin, and not some acoustic streaming effect.

The process of creating such loud sounds burned out a number of speakers, so to prevent this, [Ben] monitored the temperature of a speaker coil at varying amounts of power. He realized that the resistance of the coil increased as it heated up, so by measuring its resistance, he could calculate the coil’s temperature and keep it from getting too hot. [Ben] also tested the radiometer’s performance when the chamber contained other gasses, including hydrogen, helium, carbon dioxide, and sulfur hexafluoride, but none worked as well as air did. It’s a bit counterintuitive that none of these widely-varying gasses worked better than air did, but it makes sense when one considers that speakers are designed to efficiently transfer energy to air.

It’s far from an efficient way to convert electrical power into motion, but we’ve also seen several engines powered by acoustic resonance. If you’d like to hear more about the original Crookes radiometers, [Ben]’s also explained those before.

“Vogliamo Hackerarvi Ancora!”. La NSO Group non ci sta nella causa di WhatsApp per Pegasus

L’azienda israeliana NSO Group ha presentato ricorso contro una decisione di un tribunale federale della California che le vieta di utilizzare l’infrastruttura di WhatsApp per diffondere il software di sorveglianza Pegasus.

La vicenda, aperta ormai da diversi anni, trae origine da una denuncia di WhatsApp dopo la scoperta di un attacco su larga scala ai propri utenti. L’operazione sfruttava vulnerabilità “zero-day” e tecniche “zero-click”, permettendo l’installazione dello spyware senza alcuna azione da parte delle vittime.

Lo scorso ottobre la giudice Phyllis Hamilton ha stabilito che i server di WhatsApp erano stati impiegati in maniera impropria, consentendo l’infezione di circa 1.500 dispositivi. Secondo la sentenza, NSO avrebbe aggirato i sistemi di sicurezza della piattaforma e instradato traffico malevolo attraverso la sua rete. Da qui l’ingiunzione che impedisce all’azienda di continuare a sfruttare l’infrastruttura del servizio di messaggistica per distribuire malware.

NSO Group, nel tentativo di ribaltare la decisione, sostiene che il divieto mette a rischio la sopravvivenza stessa dell’azienda e compromette le attività di governi e agenzie di sicurezza che utilizzano Pegasus per indagini e operazioni contro il terrorismo.

La società accusa inoltre il tribunale di aver frainteso il funzionamento del software e di aver interpretato in modo errato il Computer Fraud and Abuse Act statunitense, influenzando così l’esito del procedimento.

Dal canto suo, WhatsApp respinge le argomentazioni di NSO e considera il ricorso un ulteriore tentativo di sottrarsi alle responsabilità.

Un portavoce della piattaforma ha ribadito che manipolare le comunicazioni degli utenti e sostituire i meccanismi di sicurezza viola la legge americana, e ha annunciato l’intenzione di chiedere la conferma definitiva del divieto in appello.
