When you get a Jetson Nano Developer Kit, the first thing you need to figure out is how to power it. Should you use the Micro USB port with the same 5V 2.5A power supply you use on a Raspberry Pi? Or should you invest in a 5V 4A barrel jack power supply? Here's the short answer.

The easiest way to setup a Jetson Nano for headless WiFi is to use a USB adapter. The EdiMax EW-7811Un is popular for use with the Raspberry Pi. It can also be used with a Nano, but requires a command line setting to get it to act reliably. I will show you how to do that below.

Instead of buying a case for your Raspberry Pi, why not just prop it up on standoffs? For the price of a case you can buy a small pack. You can use one pack to prop up several boards, attach HATS or even stack your boards together. But what type and size do you need?

When I received my Raspberry Pi NoIR Camera I wanted to try it out on a headless Pi 3. The problem is that the camera doesn’t display anything when you connect over VNC or Remote Desktop. Sure I could have hooked up a monitor, keyboard and mouse. But how is that going to help me when I want to build something like a wireless crittercam?

I prefer to write code on my Mac and then push it to the Pi. That way I don’t have to try to find the Pi version of development tools and editors that I like to use. It also keeps junk off the Pi leaving it lean and mean. This is fine for interpreted languages. But when I want to write code in C or C++ this becomes a problem.

To connect my Pi Zero 1.3 over WiFi I ordered an adapter from AdaFruit. The white cable in the picture is a Micro-USB adapter. Before you can get the WiFi to work, you need to connect to the Pi Zero so that you can edit a file. Because there is only one USB port, you need to look at a few options.

I’ve heard many stories of drones, Pi-based and not, flying off never to be seen again. You wouldn’t want to lose 6 months worth of work would you? Fortunately, there is a command line tool that you can use to copy images from the SD card. That way if you lose your Pi or the SD card is corrupted, you have a backup.

Recently I wrote an article titled How to Control an Arduino Uno with NodeJS. In it I discussed how to control an LED over HTTP using an Arduino hooked up to a host using NodeJS and the johnny-five library. In this article I’m going to expand on that to show how to use a similar technique to control a couple of micro servos.

In this tutorial I’m going to show you how to drive an Arduino Uno using NodeJS. The Arduino Uno is a popular microcontroller board for hobbyists. You can control things wired to it like LEDs and motors. To program it you write code in an IDE and then upload the code to the board. The upload happens over a USB cable.
