If you’ve ever wanted to build your own watch, the ChronoWatch X2040 DIY watch allows you to do it the easy way with a Waveshare RP2040-Touch-LCD-1.28 touch LCD board, a 3D-printed case, a 3.7V LiPo battery, a few screws, and firmware using the Pico C/C++ SDK. When Vishal Soni decided he wanted to build a watch, he initially planned to design a custom board, but since there are already several round LCD boards based on Raspberry Pi RP2040 MCU, he went with a Waveshare board, preferring to spend more time on firmware programming. ChronoWatch X2040 parts: Waveshare RP2040-Touch-LCD-1.28 with Raspberry Pi RP2040 MCU and 1.28-inch round touch display – About $23 to $29 on Amazon, AliExpress, or the Waveshare store. 3D printed case designed with Tinkercad 3.7V 950mAh Lipo battery (35 x 25 x 10 mm) M2 4mm screw M2 heat inserts 2-pin MX1.25 connector 1mm heat shrink sleeve tube […]
Sovol M1D hybrid IDEX 3D printer features 6 interchangeable toolheads for multi-color and multi-material prints (Crowdfunding)
Sovol has launched the M1D, an open-source IDEX (Independent Dual Extruder) 3D printer with a fixed dual-extruder architecture and interchangeable toolheads that support up to seven independently heated toolheads (one fixed and six swappable). It comes in two variants: the open-frame M1D Essential and the M1D Advanced, which adds a full enclosure and a chamber heating module capable of reaching up to 60°C. The M1D uses a patented automatic tool changer for swapping print heads in as little as five seconds and supports Single, Multi-Head, Copy, and Mirror printing modes. It enables multi-material or/and multi-color prints, including adding water-soluble support to a print to remove the need to manually remove support (see video at the end of this post for demo). The printer targets makers, engineers, prototype development, and small-scale production by reducing purge waste while improving printing efficiency and material flexibility. Sovol M1D specifications: Printing technology – FDM (Fused Deposition Modeling) Storage – […]
Arduino UNO Q Arcade bundle lets you build a custom retro gaming console for about $90
Arduino UNO Q Arcade bundle is a kit designed to build a custom retro gaming console. The bundle combines the Arduino UNO Q 4GB SBC with a set of daisy-chainable Modulino I2C modules, allowing users to create a custom game controller without requiring complex wiring or breadboards. The kit relies on Qwiic connectors to daisy-chain the input modules, whose data is then processed by the UNO Q to emulate standard HIDs for gaming or development. The plastic parts can be 3D printed by the user. Arduino UNO Q Arcade bundle contents: Arduino UNO Q 4GB – A Qualcomm Dragonwing QRB2210 SBC with an onboard eMMC, running Debian Linux Modulino Joystick – An I2C node configurable for simulating D-pad inputs or mouse cursor movements Modulino Buttons – An I2C node for mapping single keystrokes, multi-key shortcuts, or mouse clicks Modulino Movement – A 6-axis IMU node for motion-based mouse control Note: […]
Raspberry Pi Touch Display 2 – 10″ Portrait review, 3D printed VESA mount
Raspberry Pi has just announced the “Raspberry Pi Touch Display 2 – 10″ Portrait”, and we’ve received an early review sample for testing. The new 10.1-inch Raspberry Pi Touch Display 2 is a multi-touch portrait panel for Raspberry Pi designed for interactive projects such as tablets, entertainment systems, and information dashboards. The new 10.1-inch model follows the original 7-inch Raspberry Pi Touch Display 2 launched in 2024 and the 5-inch Raspberry Pi Touch Displays 2 introduced in 2025. I reviewed the 7-inch model with the Raspberry Pi AI camera and a Pi 4, and I just gave away the 5-inch variant. In this short review, I’ll show how to mount a Raspberry Pi 5 to the Raspberry Pi Touch Display 2 – 10″ Portrait, install it on a VESA mount, and test features such as 10-pin capacitive touch and display orientation. But let’s start with the specifications first. Raspberry Pi […]

BIGTREETECH Panda Sense Pro 8-in-1 smart air quality monitor works with Home Assistant and Klipper for 3D printers
BIGTREETECH (BIQU) has introduced the BIQU Panda Sense Pro, an 8-in-1 smart air quality monitor designed for 3D printing environments such as home workshops, maker spaces, and print farms. It continuously measures airborne particles, gases, temperature, and humidity, helping users monitor indoor air quality while printing. The device also integrates with Klipper-based printers and smart home platforms, making it suitable for both standalone monitoring and automated environmental control. It combines laser particle, NDIR CO₂, and electrochemical formaldehyde sensors to monitor PM2.5, PM10, CO₂, HCHO, eTVOC, AQI, temperature, and humidity in real time. The monitor features a 3.5-inch 480×320 TFT display, 2.4 GHz Wi-Fi with MQTT, USB Type-C power, 24-hour and 30-day data logging, and upcoming app-based remote monitoring. It integrates with Moonraker (Fluidd/Mainsail) and Home Assistant for automation, such as controlling fans or air purifiers based on sensor readings.

Creality Sermoon S1 review – Part 3: 3D scanning with Khadas Mind 2 and NVIDIA GeForce RTX 5060 Ti 16GB dock
At the end of last year, I received a Creality Sermoon S1 high-end 3D scanner for review. After checking the specifications and going through an unboxing in the first part of the review, I used the 3D scanner with an Intel Core i5-13500H laptop with 16GB of RAM running Creality Scan 4 software on Windows 11. The laptop specs were below the minimum hardware requirements (NVIDIA GPU, 32GB RAM), and while I managed to scan a face and bust using infrared mode, it was a struggle with 4 to 5 FPS scanning, and I wasn’t able to use Blue light scanning at all. Luckily, shortly after the review, Khadas informed me they planned to send a Khadas Mind Graphics 2 dock featuring an NVIDIA GeForce RTX 560 Ti 16GB graphics card and a Mind 2 mini PC with 32GB of RAM and an Intel Core Ultra 7 155H 16-core Meteor […]
