At the Ente Keralam Expo 2025 in Kerala’s Alappuzha, a young electronics and communication engineering graduate from Kerala showcased a voice-powered device he invented, one that writes what you speak ...

You might think that CD players and DVD players have had their run, but as it turns out, they are absolute goldmines for DIY projects. Pop one open and you'll find stepper motors, laser assemblies, ...

Witness a jaw-dropping beauty transformation reveal. This video captures the full transformation experience, highlighting the emotional, creative, and personal impact a hairstyle can have. You'll see ...

Abstract: This study explores the implementation of a GRBL and Arduino-driven Cartesian robotic arm integrated with depth sensor for harvesting bell peppers in protected cultivation. Utilizing linear ...

In adding an alternative cutter drive motor (‘spindle’) to an existing cnc machine, an electrically isolated pwm to analogue converter is needed. The machine uses a ‘grbl’ controller, which has an ...

Rarely a week goes by that some company doesn’t offer to send us their latest and greatest laser. You know the type — couple of aluminum extrusions, Class 4 diode flopping around in the breeze, and no ...

Isolated 12V limit switch input on all 4 axes. Isolated standard Grbl spindle control outputs (5V): Cycle Start, Feed Hold, EStop and Safety Door. 9x Opto-isolated inputs including standard Grbl ...

Abstract: The proprietary control of CNC machines results in the inability to control and enhance inputs because the program codes cannot be modified owing to their distribution by vendors in the ...

I have what I think is a good puzzle. GRBL 1.1h, 'real' Arduino Uno R3, ZenToolworks 12x12 CNC, Nema 23 steppers, TB6560 driver board. 24V 5A supply. Gantry has a LaserTree 10W laser. Using Win10 with ...
