💡3D printer that can mine Bitcoin uses excess heat for temperature control

PizzAndy created a 3D printing prototype that mines Bitcoin. The hybrid device is based on an open-source 3D printer design with a custom bed that is heat-controlled by throttling the Bitcoin mining ASICs attached to it. The printer bed is basically a heatsink.

The compact prototype is capable of a humble 500 GH/s when the bed is at 75 °C, says PizzAndy, but there are already plans for scaling and a tile-based model using Intel ASICs targeting at least 10 TH/s.

PizzAndy says the thought initially popped into his head 5 years ago, when he was heating his basement workspace (in the cold months) to help his 3D printers work better. The 3D printer/BTC enthusiast thought it would be “a cool thing” to mix these two technologies, but wasn’t sure about its commercial value. Since that time, he has become convinced that a commercial product is worthwhile.

🤖 Nexperia China claims to be making chips using 12-inch wafers

Chipmaker Nexperia's Chinese subsidiary said that it has ​begun producing its own chips, a further step ‌towards independence from its Dutch parent as a dispute that has disrupted automakers' supply lines continues.

The company has started making ​several types of chips also produced by Nexperia, ⁠but using 12-inch wafers - a size the Dutch company ​cannot manufacture in Europe - ​to make ⁠products including bipolar discrete devices, Schottky rectifiers and electrostatic discharge devices. The most likely supplier is WingSkySemi, a 12-inch wafer fab in Shanghai.

These chips are simpler than IGBTs, the insulated-gate bipolar transistors used for current regulation in applications like EVs and industrial equipment. The announcement demonstrates how far the company’s Chinese subsidiary has moved toward building a self-contained supply chain since its spat with Nexperia proper began in late 2025.

🔥 2026 is shaping up to be another defining year for XRP

Recently, Brad Garlinghouse, Ripple CEO, and Monica Long, Ripple's president, along with others on the Ripple leadership team traveled to Dublin, London, Singapore and Sydney to meet with the Ripple Team.

A few notes from the road:

🔥 Centers of gravity are never stagnant, and getting out of the US coastal mindset is imperative. It is necessary to think globally.

🔥 Ripple is championing a maniacal focus and eliminating bureaucracy for employees to be owners. Activity ≠ progress.

🔥 Adoption doesn’t happen overnight. Platforms are better than point solutions.

🔥 AI is becoming a fundamental part of Ripple products – especially in cash forecasting and liquidity management in real-time for the office of the CFO, but the end goal is much bigger.

🔥 2026 is shaping up to be another defining year. Ripple in the right markets with the right capabilities across payments, custody, liquidity and treasury management. There's a huge opportunity ahead and XRP is at the center of it.

🇺🇸 'America is now the crypto capital of the world,' CFTC's Selig says as digital asset rules take shape

U.S. Commodity Futures Trading Commission Chair (CFTC) Michael Selig said that "America is now the crypto capital of the world" during speech at the FIA's annual industry conference. The CFTC is drafting a crypto asset taxonomy and providing registration guidance for non-custodial software developers, while also reviewing rules for leveraged retail commodity transactions and the classification of true crypto-perpetuals.

"The U.S. is at the beginning of another great wave of innovation, as markets continue to digitize and crypto assets become mainstream," - said Selig.

The CFTC chair pointed to the adoption of blockchain technologies, crypto assets and smart contracts as forces introducing new methods for trading, clearing, settling and collateralizing commodity price exposure, alongside artificial intelligence systems executing orders at speeds and volumes far beyond human capacity.

🤖 Dolphin-shaped robot removes dangerous oil spills with 95% purity filtering system

Engineers at RMIT University in Australia have built a remote-controlled robotic “Electronic Dolphin” designed to vacuum oil from the surface of water using a filter inspired by sea urchins. Its dolphin-like shape allows it to move easily across the surface while collecting contaminated liquid. At the front of the robot sits a specially designed filter. A small pump draws oil through the filter and into an onboard storage chamber.

The current prototype runs for about 15 minutes on its battery. Engineers expect future versions to run longer as pump power and storage capacity increase. By combining robotics with specialized materials, the research team aims to create a faster and safer way to remove oil from sensitive waterways without putting human responders at risk.

🤖 New photonic chip runs AI in trillionths using light, cuts heat and energy use

Researchers at the University of Sydney have built a nanophotonic chip prototype that performs AI calculations using light instead of electricity. The experimental device processes information using photons, allowing operations to take place in trillionths of a second.

Instead of relying on electronic signals, the chip carries out calculations as light travels through nanoscale structures embedded in the device. To evaluate the prototype, the research team trained the chip to classify more than 10,000 biomedical images. The photonic neural network could identify images with an accuracy between 90% and 99%.

AI is increasingly constrained by the energy consumption. Photonic computing could help reduce that burden because light can travel through materials without electrical resistance, significantly lowering heat generation and power use compared with electronic chips.

💻 Human brain cells set to power two new data centers, thanks to 'body-in-the-box' CL1

Cortical Labs, the Australian tech startup behind the CL1 biological computer, has just announced a new partnership with data center company DayOne to establish the 2 data centers, powered by the ‘body-in-the-box’ CL1s, in Australia and Singapore. The company has already appeared with an update just a week ago that showcased its ability to play DOOM.

The CL1 units consist of a silicon chip with 200,000 lab-grown human neurons ‘grown’ on top, converted initially from human blood cells. These neurons respond to electrical stimuli to and from the chip, forming networks like the neural arrays in our own brains. The system is shown to be able to learn and adapt, with the CL1 equipped with life-support features that keep the conditions suitable for the neurons to remain alive for up to 6 months.

A facility in Melbourne, Australia, will consist of 120 CL1 units, but it expects its joint project in Singapore with DayOne to have about 1,000 units. The neural approach used by the CL1 requires far less energy than a typical computer, requiring only a fraction of that used by conventional AI chips.

🛰 FCC says Amazon must focus on its own buildout, not SpaceX

The head of the Federal Communications Commission (FCC) chastised Amazon.com Inc. for filing a petition critical of rival satellite operator SpaceX while Amazon itself is behind on meeting deployment obligations. FCC Chairman Brendan Carr suggested that Amazon overstepped in a request for regulators to deny SpaceX’s plan for a 1 million-satellite constellation.

"I think ⁠Amazon should focus on getting Amazon's house in order with their own launches and their own satellite constellation, rather than worrying about other people that are ‌actually ⁠out there launching satellites at the pace and cadence that SpaceX is," - FCC Chair ⁠Brendan Carr told.
