    3D Printer Revolution: Prusa ColorMix for Color Printing

    Key Takeaway

    – Multicolor 3D printing with affordable devices now possible without manual filament changes
    – Prusa ColorMix achieves mixed colors by stacking different colored layers in depth, not on the surface
    – Mixing ratio and number of producible colors are limited
    – Workflow simplified with settings directly in PrusaSlicer and EasyPrint
    – CMYKW set in development for more reproducible results; filament shade consistency and color-accurate monitors matter for best outcomes

    Multicolor 3D Printing Gets a Upgrade with Prusa ColorMix

    3D printing in multiple colors is now possible even with relatively affordable devices without having to change individual filaments manually. If only one print head is used, however, cutting the filament and therefore generating waste is unavoidable. Users are also naturally limited to the colors they have available as filament. Prusa ColorMix, a new system released under the MIT license, has now been introduced and could significantly simplify multicolor printing in terms of material requirements.

    How the Technology Works for Better Color Mixing

    The basic principle does not fundamentally differ from conventional two-dimensional color printing. The human eye has limited resolving power, so differently colored dots effectively blur into a mixed color. However, Prusa ColorMix does not alternate the dots across the surface but in depth. The layers stacked on top of each other then form the mixed color. There are limitations. For example, the mixing ratio cannot be freely selected, and the number of colors that can be produced this way is also limited. According to Prusa, the workflow itself has been significantly simplified, with the corresponding settings available directly in PrusaSlicer and EasyPrint.

    Development of CMYKW and Color Accuracy Considerations

    A CMYKW set is also in development, which could lead to more reproducible results. Optimal results should only be expected if the source filaments match the same shade across batches, not just the same basic color. The integrated color mixing model is intended to predict which color will actually be produced in a print. In such cases, a monitor that is not necessarily calibrated but at least reasonably color-accurate could become relevant.

    Additional Insights and Recommendation for Readers

    Prusa’s blog post is also recommended beyond the announcement itself, as it discusses various color mixing models and the insights gained during development. The system aims to make multi-color printing more accesible while reducing waste, although users must still consider filament batch consistency. Understanding these limitations helps in achieving the best possible print results.

  • Best Budget Drone with Display Controller

    Best Budget Drone with Display Controller

    Key Takeaway

    – Affordable drone priced around $70 but only available as direct import with possible extra shipping and import fees
    – Severe limitations: control range of 330 feet, WiFi transmission, and 720p HD camera
    – Lightweight at 190g, avoiding 250g legal limit, with optical flow positioning but no GPS
    – Flight time of ~12 minutes with 60-minute charge; toy-like aerial roll feature
    – Supports smartphone connection (Android/iOS) and basic flight planning via display

    Affordable Drones and Their Limits

    There is a large selection of affordable drones, many of which are only available as direct imports. The YL01 is one such cheaper drone, with a current price of around $70. That gets customers the model with one battery. Additional shipping costs are charged. Import fees may apply depending on the buyer’s location. At first glance, the specifications are fairly decent. For this comparatively low price, customers get the drone itself and a remote control with a display.

    Transmission and Camera Constraints

    However, the transmission distance for both the control signals and the live video feed is severely limited. The specified 330 feet for the control signals is not comparable to higher-quality drones, such as those from DJI. Data transmission takes place via WiFi. According to the manufacturer, the camera offers HD resolution, meaning 720p rather than 1,080p. The takeoff weight is listed at 190 grams, so the gadget remains below the legal 250-gram limit in some regions. Optical flow positioning is supported. Accordingly, the camera’s image signals are processed for positioning.

    No GPS but Smartphone Compatability

    There is no GPS module, although this would probably not be particularly useful anyway given the short range. In practice, the drone would no longer be reachable for control signals. However, it should still be possible to draw a flight plan on the display, which the drone then follows. The drone can roll in the air, which is more of a toy feature. Flight time is listed at around 12 minutes, with charging taking 60 minutes. Accordingly, even two batteries would not allow continuous operation. A smartphone connection is possible. Both Android and iOS devices are supported.

    Battery and Pricing Details

    This drone is avalible from retailers like Banggood, with a current price of around $70 for the single battery version. Extra shipping charges may apply, and import fees can vary depending on your location. The takeoff weight is 190 grams, so it remains under the 250-gram limit in many regions. The specified 330 feet for control signals is quite short, and the WiFi based video feed is limited to 720p HD resolution. Optical flow positioning is supported, but there is no GPS module, which makes sense given the short range. The drone can perform aerial rolls, which is a fun toy feature, but flight time is only about 12 minutes with a 60 minute charge time. A smartphone connection is possible, supporting both Android and iOS devices, and you can draw a flight plan on the display for the drone to follow.

  • PiEEG XR Real-Time Brain Activity Measurement for VR

    PiEEG XR Real-Time Brain Activity Measurement for VR

    Key Takeaway

    – PiEEG XR is an EEG-based input device for XR/VR that measures brain activity through a replacement face cushion with built-in electrodes.
    – Data is processed via ironbci at 250 data points per second with Bluetooth communication for wireless VR headset compatibility.
    – Funded through Kickstarter, targeting makers, researchers, and consumers with multiple versions (Mask, Research Kit, All-in-One) and native VRChat support.
    – Backed by expert Ildar Rakhmatulin; APIs and SDKs enable flexible use without strict manufacturer limitations.

    So, the PiEEG XR is this new interface for XR and therefore also for applications such as VR. It is essentially an input device that functions as an EEG system. The abbreviation stands for electroencephalography and ultimately refers to the measurement of brain activity. It should be noted right away that the system will be funded through a Kickstarter campaign and is not necessarily a typical consumer product, alot of people might not realise this. Instead, it is also aimed at makers and researchers. APIs and SDKs are intended to allow use in a wide range of contexts and without strict manufacturer specifications. The project is also backed by Ildar Rakhmatulin, a recognized expert in this field who has already attempted to bring other projects to market.

    Hardware and Sensing Capabilities

    At the hardware level, the PiEEG XR is essentially a replacement face cushion. Electrodes are built into it, which are then responsible for measuring brain activity. Data processing is handled by ironbci, which can record 250 data points per second, wich is quite fast. This should also enable high temporal resolution. Communication takes place via Bluetooth, which should be very practical in the era of fully wireless VR headsets such as the Pico 4 Ultra that we have already tested. The system will be available as the PiEEG XR Mask, as a research kit with ironbci and as an all-in-one version for consumers.

    Pricing and Availability Details

    • PiEEG XR Mask: This is the base model designed for makers and tinkerers, pricing details are announced via Kickstarter.
    • Research Kit with ironbci: A more advanced package for scientific studies, includes the ironbci software for high-resolution data logging.
    • All-in-One Version: A complete consumer oriented kit for those who want plug-and-play functionality, featuring native VRChat compatibility.

    Native VRChat compatibility is advertised as a key feature. This essentially means that the device can directly interface with the popular social VR platform, allowing for brain-controlled interactions wich is really impressive. The campaign will likely offer early bird discounts for backers who pledge during the first few days, though exact price tiers have yet to be fully revealed. Its important to follow the campaign closely if you are interested in this kind of neurotechnology.

  • Foldable 300W Power Bank with Solar & Built-in Charger

    Foldable 300W Power Bank with Solar & Built-in Charger

    Key Takeaway

    – Integrated plug folds down for travel, available in US, EU, and UK versions
    – USB-C cable doubles as a lanyard; supports up to 100W transmission
    – 74 Wh capacity with up to 300W combined output; charges laptops via 140W USB-C ports
    – Solid-state design prevents thermal runaway under physical stress
    – High crowdfunding risk; $89 starting price with shipping expected in August

    A new power bank could be interesting for travelers or for anyone who wants to use a power bank without an additional charger. The Solly comes with an integrated charger and a plug. The model is offered in versions with a US, EU and UK plug. This plug simply folds down, which means it should not get in the way during transport.

    The 3.1 x 2 x 1.4-inch gadget comes with a USB-C cable

    Which also functions as a lanyard and should make it easier to carry. Up to 100 watts can be transmitted via the USB-C cable. The weight is listed as 14.1 oz. In an emergency, the built-in solar panel is also supposed to provide a certain amount of charge. According to the manufacturer, the power bank has a capacity of 74 Wh, which should be enough to fully charge typical smartphones more than once.

    It supports output of up to 300 watts

    As usual, this figure refers to the combined output across all ports. The two USB-C ports are said to deliver up to 140 watts each, which should be enough to charge laptops. USB-A can still deliver 20 watts. The Solly can be charged not only with the integrated plug but also via USB-C at up to 140 watts. This is a solid-state power bank, so it should not go into thermal runaway even under severe physical stress.

    As part of the crowdfunding campaign

  • New Casio G-Shock GA-2100 Collab Watch Launches

    New Casio G-Shock GA-2100 Collab Watch Launches

    Key Takeaway

    – New regional store exclusive G-Shock (GA-2100-7APRY-KIT) for Yunnan, China.
    – Collaboration with artist Cui Xinwen featuring Lucky Elephant motif on both sides of the strap.
    – Includes collectible packaging and a lanyard with three detachable enamel charms.
    – Based on standard white GA-2100 platform (carbon-reinforced resin, 20 BAR water resistance).
    – No pricing or wider availability announced yet.

    Casio’s New Yunnan Store Special

    Casio have relesed a new regional shop only G-Shock built on the GA-2100 platform that was created in collaboration with Chineese artist Cui Xinwen. The GA-2100-7APRY-KIT is exclusive to the Yunnan City G-Shock store and themed around the region using a Lucky Elephant motif, which is a fitting choice since Yunnan province is the only place in China were wild Asian elephants still roam. No pricing or wider availability has been announced.

    Watch Construction and Design Details

    The watch itsself uses the standard white GA-2100 base — carbon fiber-reinforced resin case, black dial, analog-digital module with 20 BAR water resistance — but the collab work is concentrated on the band. Cui Xinwen’s Lucky Elephant character, which is rendered in black ink illustration style, apears many times across the full length of both strap sides in differnt poses, and the blue strap holes are present for contrast against the white band. The case back carries a black-on-dark-dial dial layout that keeps the overall appearance fairly clean, so the strap does most of the visual work.

    Kit Contents and Charm Details

    The “KIT” suffix in the model name also carries importance, because besides the watch, the package includes a black-and-white checkered rope lanyard holding three enamel charms from Cui Xinwen’s character universe — a blue elephant in a red mushroom cap, a dancing yellow figure, and a teal abstract form. The charms are attatched via swivel clasps, meaning they can be mixed or unattached independently, and the packaging itself is a collectors item with a sturdy light-blue box wrapped in full-coverage artwork featuring the Lucky Elephant which @geesgshock — who was among the first to share images internationall — confirmed arrived in May.

    Regional Exclusivity History

    Casio have form with China region store exclusives on the GA-2100 platform, most recent being the Guiyang store’s GA-2100HDS-7A1PRG last year, and this follows the exact same playbook. No pricing or more wider availability has been announced by the brand at this time.

    • Carbon fiber-reinforced resin case
    • Black dial with analog-digital module
    • 20 BAR water resistance
    • Black ink illustration style strap
    • Blue strap holes for contrast
    • Three enamel charms included

  • Astronomers: Red Dwarfs Devouring Earth-Like Planets

    Astronomers: Red Dwarfs Devouring Earth-Like Planets

    Key Takeaway

    – Red dwarfs unexpectedly contain lithium, which their internal heat should have destroyed.
    – The lithium likely comes from red dwarfs absorbing matter from Earth-like planets.
    – This discovery reveals the destructive behavior of red dwarfs toward planetary systems.
    – The finding may help researchers understand how planetary systems form.
    – Further studies with new instruments are needed to identify similar stars.

    By observing various regions of the universe, astronomers sometimes find surprising phenomenons. Indeed, after discovering a collision between two neutron stars and an exoplanet with a potential atmosphere, they have detected red dwarfs absorbing matter from Earth-like planets.

    A Surprising Discovery in Stellar Observations

    This discovery was revealed in a new study published in the Monthly Notices of the Royal Astronomical Society. Several researchers from Keele University and the University of Exeter have studied thousands of stars and discovered six red dwarfs exhibiting unusual behavior. The team spent months cross-referencing data and found that these specific stars were not acting as expected.

    Lithium Anomaly Detected

    After conducting various observations, they noticed that these stars contained lithium. However, this chemical element should not be present in these celestial objects, as explained by Professor Robin Jeffries of Keele University, and lead author of the study:

    “Red dwarfs are smaller and cooler than our Sun but inside they are extremly hot. This heat should destroy all of their fragile lithium in nuclear reactions shortly after they form.”

    Implications for Planetary System Formation

    Therefore, according to astronomers, these stars, which are the most common in the universe, could have absorbed matter from Earth-like planets. Thus, while this discovery highlights the destructive behavior of red dwarfs, it could also help researchers understand how planetary systems form. However, further studies will need to be conducted in the future using new instruments to identify stars with the same behavior.
