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.

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.
