In terms of such components, the A-CORE range uses the MK2 line’s Air Motion Transformer tweeter, which is said to offer “ultra fast transient response and lifelike detail”. The speakers also utilise the same Honeycomb compound woofer, heavy-duty MDF cabinets, and 100W Class D-ICE power amplifier.
The A-CORE speakers are designed with analogue performance in mind, and could suit both artists and sound engineers or music fans eager for simple, authentic playback.

Tornado Cash dev's attorneys say prosecutors hid exculpatory evidenceAttorneys for Tornado Cash developer Roman Storm filed a motion asking the court to reconsider the motion to dismiss the case due to the prosecution withholding exculpatory evidence in the form of communications with the Financial Crimes Enforcement Network (FinCEN) dating back to 2023.According to a May 16 letter from Storm's attorneys to Judge Katherine Polk Failla, the FinCEN documents show that non-custodial crypto mixers do not fall under the legal definition of a "money transmitting business" and that prosecutors have known this since at least 2023.Despite having knowledge of the FinCEN guidance on crypto mixers, state prosecutors still proceeded with cases against the Samourai Wallet developers and Tornado Cash, the attorneys alleged.Letter sent by Roman Storm’s attorneys to Judge Failla. Source: Court ListenerUS prosecutors denied they withheld the evidence, claiming they submitted the FinCEN communications within the stipulated timeframe to produce the documents for the defense and the court during legal discovery.Storm's defense cited the same legal documents and the same argument the Samourai Wallet developer’s attorneys posed to the court in a May 5 legal letter. Storm's attorneys wrote:"The disclosures in the Samourai case reveal that the government, at the very least, played fast and loose and, at worst, affirmatively misled this Court with its arguments about FinCEN guidance when responding to the motions to dismiss and to compel discovery."The letter went on to argue that although the government continues to claim that the cases bear only "superficial similarities" to each other, they share the core characteristics of cryptocurrency mixers under the law, thus making the FinCEN documents salient to dismissing the case against Storm.The 2023 communications between US prosecutors and FinCEN.

Crypto elite increasingly worried about their personal safetyCryptocurrency executives and other investors with significant wealth from crypto holdings are getting more serious about personal security, according to stories this weekend in both the Wall Street Journal and Bloomberg. While cryptocurrencies have always created unique security risks, it seems there’s a rising threat of violent abduction due to the growing value of Bitcoin, […]

Speed Up Arduino with Clever CodingWe love Arduino here at Hackaday; they’ve probably done more to make embedded programming accessible to more people than anything else in the history of the field. One thing the Arduino ecosystem is rarely praised for is its speed. That’s where [Playduino]  comes in, with his video (embedded below) that promises to make everyone’s favourite microcontroller run 50x faster.
You might be expecting an unstable overclocking setup, with swapped crystals, tweaked voltages and a hefty heat sink, but no! This is stock hardware. The 50x speedup comes from one simple hack: don’t use digitalWrite();
If you aren’t familiar, the digitalWrite() function is one of the key functions Arduino gives you to operate its boards– specify the pin and the value (high or low) to drive it. It’s very easy, but it’s also very slow. [Playduino] takes a moment to show just how much is going on under the hood when you call digitalWrite(), and shows you what you can do instead if you have a need for speed. (Hint: there’s no Arduino-provided code involved; hardware registers and the __asm keyword show up.)
If you learned embedded programming in an earlier era, this will probably seem glaringly obvious. If you, like so many of us, got started inside of the Arduino ecosystem, these closer-to-the-metal programming techniques could prove useful tools in your quiver. Big thanks to [Stephan Walters] for the tip.
Of course if you prefer to speed things up by hardware rather than software, you can overclock an Arduino– with liquid nitrogen, even.

Moody's downgrades US credit rating due to rising debtMoody's credit rating agency downgraded the credit rating of the United States government from Aaa to Aa1, citing the rising national debt as the primary driver behind the reduction in creditworthiness.According to the May 16 announcement from the rating agency, US lawmakers have failed to stem annual deficits or reduce spending over the years, leading to a growing national debt. The rating agency wrote:"We do not believe that material multi-year reductions in mandatory spending and deficits will result from the current fiscal proposals under consideration. Over the next decade, we expect larger deficits as entitlement spending rises while government revenue remains broadly flat."The credit downgrade is only one degree out of the 21-notch rating scale used by the company to assess the credit health of an entity.An overview of the US national debt. Source: US National Debt ClockDespite the negative short to medium-term credit outlook, Moody's maintained a positive outlook on the long-term health of the United States, citing its robust economy and the status of the US dollar as the global reserve currency as strengths, reflecting "balanced" lending risks.Related: Asia’s wealthy shifting from US dollar to crypto, gold, China: UBSInvestors react to Moody's US credit revision Moody's announcement drew mixed reactions from investors and market participants, leaving many unconvinced by the agency's revised outlook.Gabor Gurbacs, CEO and founder of crypto loyalty rewards company Pointsville, cited the rating agency's previous credit assessments during times of financial stress as unreliable, signaling that the outlook was too optimistic."This is the same Moody’s that gave Aaa ratings to sub-prime mortgage-backed securities that led to the 2007-2008 financial crisis," the executive wrote in a May 17 X post.However, macroeconomic investor Jim Bianco argued that the recent Moody's credit outlook does not reflect a real downgrade in the perception of US government creditworthiness and characterized the announcement as a "nothing burger."Interest rates on the 30-year US Treasury Bond spiked to nearly 5% in May 2025, signaling reduced long-term investor confidence in US debt.

This Extra-Large, Two-Stage Fume Extractor Really SucksSolder fumes are not nice on the lungs; nor are fumes from superglue, epoxy, or a whole mess of other things we often find ourselves using on the bench. Some people might be able to go the fume hood route to toss that all outside, but for the rest of us, there’s fume extractors. [Raph] has produced an extra-large, carbon-filtering, two-stage fume extractor that by all accounts really sucks — it is effective at hoovering up solder fumes up to 10″ from its inlet.
Note the 18V tool battery in the base. That’ll go for a bit.
Even better, [Raph] built a battery box for an 18 V cordless tool battery, and broke out banana plugs so this doubles as a variable power supply via a cheap LM2596 based DC-DC converter. It also serves as a speed controller for the fans, which makes us wonder if you can adjust the PSU output and the fan speed independently…
Maximum suckage is achieved through careful baffle design. Check out the blog to see the trial-and-error process at work. Of course, having a 200 mm axial fan and 140 mm blower fan front and rear is going to move some air no matter what. Which is required to get air flow through the 38 mm thick activated carbon filter that should scrub all nasties quite nicely. We aren’t filtration experts but we can agree with [Raph]’s estimate that it will last “a while”.
If you want to roll your own, all of the STEP files are on GitHub, and [Raph]’s blog has an excellent step-by-step build guide. We’ve seen other hacks from [Raph] before, from his dovetailed modular breadboard to the machine that shaped his bed and automation for his camper van.
