This product is courtesy of It was super easy to make this mobile tracked platform and radio-controlled useful for building ...

As the valves use 24V and the motor 12V, standard N-Mosfets and power relays are used for voltage conversion. The remote controller [Gilard] used is actually 20 years old, so the output signal of ...

The controller in question is a 4QD Porter 10 so an extra component is a DC-to-DC converter to provide a floating ground for the Arduino.

Most of my Arduino code was readily available on the Arduino website and is free to download at GitHub. Near the end of my video I will show you how to build a MIDI controlled stepper motor in 40 ...

The Jackal is powered by a 450 Watt 1020z geared motor, that is more often found powering scooters and is the same motor that was used in the original Raptor. Check out the new Jackal being ...

This dc motor speed-control circuit uses standard, available components; light impinging on two independent phototransistors establishes the motor's speed. Motor speed can be adjusted by the light ...
