Build a Pico “Uno” – Prototyping with the Pico

Build a Pico “Uno” – Prototyping with the Pico

The Raspberry Pi Pico is a very powerful microcontroller, especially when compared to an Arduino Uno. Yet most of the time we reach for a board to test with, we pick an Uno! This is because the Uno is easier to prototype with.

Well, today we’ll change all that and build three different “Pico Uno” boards that have the power of the RP2040 and the ease of use of an Arduino Uno.

e-Paper with Arduino & Raspberry Pi

e-Paper with Arduino & Raspberry Pi

e-Paper displays have a number of unique features, such as being visible in broad daylight, consuming very little current, and retaining their image when powered down. But they also have some disadvantages – they have poor refresh rates, limited color capability, and are more expensive than other display types.

in some applications, however, e-Paper is a perfect choice, and today we will see how to use these displays with both an Arduino and Raspberry Pi.

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!
