Getting Started with an Arduino Nano in Ubuntu 16.04 LTS

Hey everyone, today we’re going through the initial setup of an Arduino Nano that I had received as a gift from a friend. This is a simple tutorial where we’ll be loading up a script (built into the software) in Ubuntu in order to make an LED light fade in and out. I’m basically writing this because there was an annoying little user privileges hiccup I hit as well as realizing that the install script on the Arduino website (as of April 2017) seemed to contain an error and I wanted to have the updated code here as well for you.

Precious Metals Spot Price Display

RetroPie Setup on the Raspberry Pi Zero v1.3

The purpose of this article is to get you started with the initial setup of RetroPie on the Raspberry Pi Zero. What's awesome about this project is that anybody can jump right in and do it since there's literally no previous coding knowledge necessary. The setup was a lot easier on the Raspberry Pi 3 (and RetroPie does run faster on it) but I wanted to write a quick tutorial for the Zero since there were a few more steps in setting it up due to the limited USB ports. I'm assuming you already know this but these boards are hard to find although I was able to snag one from Adafruit's website. Be sure to checkout RetroPie's official website and GitHubsite.

Search for Extra Terrestrial Intelligence (SETI) using BOINC via the [email protected] Project


The purpose of this article is to get your Ubuntu based personal computer or server, up and running with a citizen science project known as [email protected]running BOINC to do so. BOINC is a program that lets you donate your toaster's idle computer time to science projects like [email protected] which this article is about. Other projects include Climateprediction.net, [email protected], World Community Grid, and several others. Below I have a brief background on the SETI program and the distributed [email protected] program that I assume you’re here for so feel free to skip to the Getting Started section below if you’re already familiar with history.
