Cycloidal gearboxes are a recurring theme in the hobbyist space due to the performance they promise in a compact package.

If you’re building your first plotter, or you just like thinking in right angles, you’d probably consider a Cartesian design ...

I assembled the main body of the microscope using individually-purchased LEGO bricks. Instead of using motors and gears from LEGO Technic, I designed custom actuators using FreeCAD software and ...

DC motors are widely used in industries to convert electrical energy into mechanical energy. The rotational movement of the motor shaft provides the power required for various applications like ...

This is a solder paste dispenser. The controller supports unipolar and bipolar stepper motors, a foot pedal switch, an OLED display, a LED that blinks faster when the motor runs faster, and a menu ...

The accurate and precise transport of the small amounts of the liquid by the syringe pump is widely used in many fields. In this paper, an Arduino-based syringe pump is fabricated using the computer ...

A low-cost multispectral imager was built using a multiwavelength LED PCB (light-emitting diode printed circuit board), 3D printed housing, and a monochrome camera, and it was controlled via National ...

Regulations are not only prevalent in technology, but are also commonly found in nature. The construction of self-balancing robots can serve as a preliminary stage of androids, since movement on two ...

A stepper motor is a type of DC motor that works in discrete steps and used everywhere from a surveillance camera to sophisticated robots and machines. NEMA 17 stepper motor has a step angle of 1.8° ...
