Raspberry Pi Pico with CircuitPython

CircuitPython with Raspberry Pi Pico

CircuitPython is an easy-to-use language with hundreds of libraries for microcontrollers. Today we will be using CircuitPython with the Raspberry Pi Pico

With over 300 libraries already to go CircuitPython makes it easy to expose the power of the Raspberry Pi Pico.

Today we’ll see how to install CircuitPython and how to use it to build a keyboard emulator, a mouse emulator, work with MicroSD cards and flash some addressable RGB lights.

Testing Cases for the Raspberry Pi

Stress Test Raspberry Pi Cases

A Raspberry Pi case is more than just a box, it also can have drastic effects on performance. The case can affect heat dissipation, WiFi performance and access to the GPIO and other connectors.

In this article, and the accompanying video, I’ll test a number of cases to see how they perform under stress. I’ll also show you how you can use utilities like Stressberry and iPerf to check your own enclosures for the Raspberry Pi.

Build a remote Surveillance Camera using motionEyeOS & Raspberry Pi

Raspberry Pi Remote Camera with motionEyeOS

motionEyeOS is an open-source product that can turn any Raspberry Pi into a sophisticated surveillance system. It’s very easy to use as the product is available as an image file for the Raspberry PI as well as several other single board computers.

In this article we will set up both a Raspberry Pi 3B+ and a Raspberry Pi Zero W with motionEyeOS. We will then learn how to use all of the features of this amazing product. If you are looking for an inexpensive yet advanced surveillance system this could be the answer!

Hacking the Google AIY Voice Kit – Part 2- Voice Control

Hacking the Google AYI Voice Kit Part 2

Time to take a second look at the Google AIY Voice Kit. In this installment I’ll take the AIY Voice Kit out of its cardboard box and put it onto a breadboard so that I can experiment with using the kit to control devices like LEDs and DC Motors.

Follow along as I use the Google Cloud Speech API and some Python code to make the AIY Voice Kit come to life!

Using the HC-SR501 PIR Motion Sensor – With Arduino & Raspberry Pi

HC-SR501 Motion Sensor

The HC-SR501 is a Passive Infrared (PIR) motion sensor that is extremely useful. It can be used all by itself or combined with an Arduino or Raspberry Pi

In this article you’ll learn how a PIR sensor works and you’ll build some cool projects using the HC-SR501. You can even make a motion activated camera that will tell you who is stealing your Jelly Beans!
