I wanted to know how much it costs to run my Raspberry Pi 4 if I left it running for a day, a week, a month, and even a year. To figure this out, I conducted over 30 measurements of how much power my...

A frozen program running on a Raspberry Pi is likely consuming memory, power, CPU time, screen space, and is likely getting in your way. If a program is frozen it's serving no purpose except to waste...

This guide compares cloud services that a Raspberry Pi can connect to based on how easy they are to setup, and how much they cost. Raspberry Pi can send sensor data to the cloud using a REST API...

While putting together a guide on how to connect Raspberry Pi to the cloud, I realised that it wasn't a straightforward guide for helping anyone send data from a Raspberry Pi to a REST API (as is...

I measured Raspberry Pi power 36 times with different configurations of settings, running apps, and peripherals connected; I did all this to figure out how much power a Raspberry Pi is likely to use...

I tested 8 different sketches, a bunch of peripherals, and a variety of measuring tools, all to figure out how much power an Arduino uses. An Arduino typically uses between 286mW and 1,282mW of...
