Autonomous Driving AI for Donkey Car Garbage Collector

Use a TensorFlow SSD MobileNetV2 DNN on the Raspberry Pi plus Pi Camera to build an autonomous car capable of object detection. Story This project will show how to transform a (Raspberry Pi + Pi Camera ) powered RC car into one capable of object detection and autonomous driving. To do this we will deploy …

Driving a bi-polar stepper motor with the SN754410NE double H-bridge and a Raspberry Pi

Bi-polar stepping motors use only two coils and are easily recognized because they only have four wires. Most unipolar steppers can be used in bipolar mode by ignoring the two centre taps. Because bi-polar stepping motors produce the rotating magnetic field by reversing the current in both coils, controlling them is much more complicated than …

Raspberry Web server sending GET data to Arduino Nano driving 6 servos

This is a small project I did for a colleague who is building a 1/48 scale RC model of a Fletcher class Destroyer (yup…that makes the “model” about 8 feet long!) He asked if I could animate the 5 x MKIII 5″/38 gun turrets, complete with bearing and elevation, and also being able to individually …

Driving a Unipolar Stepper Motor with a ppDAQC Pi Plate

Stepper motors are versatile devices that allow precise and repeatable angular control. They are used in disk drives, translation tables, and 3D printers to name just a few applications. They typically come with two different wiring arrangements. The most common arrangement is four wires that are connected to two coils. This is called a bipolar …
