Waveshare MK20 macro keyboard features twenty mechanical keys with 0.85-inch color LCD keycaps

Waveshare MK20 Multi Functional AI Voice Control Panel

Waveshare MK20 is a multifunctional macro keyboard with twenty mechanical keys featuring 0.85-inch LCD keycaps. As an upgrade to the earlier MK10 model, it adds a 2.8-inch secondary display along with two control knobs. The device supports AI voice interaction, real-time data display, and smart home integration with Home Assistant. Like its predecessor, the MK20 relies on a dual-system architecture: an Allwinner T113-S3 dual-core Cortex-A7 processor runs Linux to drive the displays, and a GD32 microcontroller runs QMK for low-latency keyboard and knob input. Each LCD key offers 128×128 resolution and supports dynamic images, videos, and multi-layer overlays, while the 2.8-inch secondary display (428 × 142 resolution) provides status or customization information. The keyboard also includes two rotary encoders with aluminum caps for volume, playback, or timeline control. The device is built with an aluminum alloy top case and a 2.5D acrylic lens for durability. Waveshare MK20 specifications: Main Controller – Allwinner […]

LUNYEE 3018 Pro Ultra review with offline controller and Easel CNC software (Part 2)

We have already checked out the specifications, assembled the machine, and performed basic tests with the LUNYEE 3018 Pro Ultra CNC Router in the first part of the review. We’ve now had time to use the machine to carve text and logos on wood and aluminum. It was Suthinee’s first CNC machine, so the LUNYEE 3018 Pro Ultra was reviewed from the point of view of a beginner. We used both the offline controller with files provided on the SD card and the Easel web-based CNC software. Selecting and installing a drilling bit Our sample came with 1/8″ drilling bits that ship by default with the CNC router, and the optional “LUNYEE 1/4″ Shank CNC Router Bit Essential Kit” as well as ER11 collets for each kit. Selecting the bit will depend on the size of the work and the desired cutting pattern as shown below. The first step is […]

LUNYEE 3018 Pro Ultra Review – Part 1: Unboxing and assembly of the CNC Router with a 500W spindle

LUNYEE has just sent us a 3018 Pro Ultra CNC router for review. The CNC machine is an update to the 3018 Pro Max with improved performance and precision, as well as wider material support. It features a 500W spindle motor with a maximum speed of 5000mm/min, a full aluminum alloy structure, and an HGH15 linear guide X-axis that allows for reliable milling of hard materials such as aluminum, copper, and brass. Its 3-axis lead screw drive system provides smooth movement with an accuracy of ±0.1mm. The machine comes partially pre-assembled and should only take a short time to assemble. Safety features include an emergency stop switch and limit switches on every axis. It’s compatible with popular GRBL-compatible software such as Fusion360, Easel, Candle, UGS, LaserGRBL, LightBurn, and so on, and can be used for milling wood, acrylic, carbon fiber, and there’s also an option for installing a laser module, […]
