If you’ve recently ran an apt upgrade on your Raspberry Pi you might have noticed a bunch of lines scrolling up the screen saying “rpikernelhack” that freaked you out! What is rpikernelhack and why is it running on your Raspberry Pi?? Understanding rpikernelhack When the developers of the Raspberry Pi were designing the device and […]
Many people pour hours and hours into developing a project on their Raspberry Pi and never put any though in how to back up their work. A Raspberry Pi is a used a lot for prototyping and electronics learning projects. It’s a super fantastic computer for these purposes and even includes a full set of […]
This update is going to be all about the R2-D2 dome build, specifically the mechanical and electronics portion for automating the pie panels. This was actually one of the most frustrating parts so far. Not because the work was all that hard, but because much of the componentry that is sold flat out does not […]
I2C is an extremely common protocol integrated into many products. It allows serial communications between many devices over just two wires. In this tutorial we will cover how I2C works and show some real world examples. If you plan on linking multiple Arduinos or connecting an Arduino to a Raspberry Pi, its an incredibly useful […]
In this quick tutorial we will cove the right way to change the Raspberry Pi DNS settings so you can change your DNS server to Google DNS, OpenDNS, or even the DNS server from your ISP. DNS or Domain Name Service is the service which your Raspberry Pi (and all internet connected devices) convert the […]
If you’ve been doing Raspberry Pi or Arduino projects you’ve likely encountered the term I2C being tossed around, or at least seen the I2C pins on the devices and wondered what they do. Put simply, I2C is a point to multi-point serial communications bus for both on-board and off-board devices. I2C can operate at up […]
As I continue on with my journey to build an Astromech, we’ll go down several paths. We have to paint the dome panels (the top ones are called pie panels), build the frame, mount the dome, and start on the electronics which includes some custom programming. I am going to go through things in order […]
Building R2-D2 has been a lifelong dream of mine. It’s been on the playbook and my backlog of projects for many years. Quite frankly, there are a few simple reasons that I haven’t gotten to this project until now. It’s not a short project. It’s expensive. It’s complicated. Let’s break those down! Building R2-D2 is […]
One of the first questions people new to Raspberry Pi or Arduino projects usually ask is “What is PWM?” or “What is Pulse Width Modulation?” In this quick tutorial we will quickly cover this topic and hopefully make some sense out of it. In many of our articles we’ve talked about PWM conceptually, without going […]
If you’re not familiar with Flightradar24, you should be! It’s a fantastic service that tracks flights all over the world using ADS-B data. You can track ADS-B using a Raspberry Pi and send the data automatically to Flightradar24. In return for your service they will give you a $499 professional business subscription for FREE to […]
