![]() If you used a Pi 4, you will almost definitely need a separate power supply for reliability.ĭan Purdy has written a simple guide on how you can do this without any special software for his recording studio. A TV or monitor’s USB port should be sufficient. Low power draw is particularly useful if you don’t want to have a separate power supply cable running to the Pi Zero 2 W. WiFi means you can SSH to control it, or you can use it to fetch data from an API. One benefit of the Pi Zero 2 W is that it has WiFi and it has low power draw. This saves printing cost, paper usage and labour on replacing signs.Ī doctor’s office, recording studio and other appointment-based services could display a person’s appointment number and direct them to the correct room, saving a receptionist’s time. If you run a B2C business such as a museum, restaurant, recording studio, doctor’s office, you might have a use case for the Pi Zero 2 W as a signage tool.Ī museum could use digital signage to explain the exhibits, and when the exhibition is over, the signage could be updated for the next one. Which means with the Pi Zero 2, you will be able to run even more programs along with this WiFi extender. The upside is that this project ran on the original Raspberry Pi Zero W, and the engineer has stated that it can also run a Pi-Hole ad filter. Plus, unlike the Raspberry Pi 4, you will need a microUSB to USB OTG converter to connect your WiFi antenna (which will likely be USB-based). While the Pi Zero 2 allows an overall smaller package, it might be unable to power high-power antennas given its lower power rating. You will need two WiFi adapters to do this, and one of them can be the integrated WiFi from the Pi Zero 2 W. This project explains how you can use the Pi Zero 2 W as a WiFi extender. Pi Zero 2 W as digital name tag, weather display, stock ticker (with ePaper display) You can also integrate it into an existing Raspberry Pi, by following instructions under the “Installing manually” section. Installing OctoPi is done through flashing an SD card with the Raspberry Pi Imager. OctoPrint comes bundled in an Octopi OS image, which is based on the Raspberry Pi OS. It works right out of the box unlike its Zero predecessor which was underpowered. In fact, OctoPrint’s Gina Häußge recommends the Pi Zero 2. The OctoPrint is an open source software that allows you full remote control and monitoring of your 3D printer. You will go through steps including setting up the firewall, port set up, installation, configuring your router. Pi-Hole’s documentation takes you through five steps to setting it up on the Raspberry Pi. Pi-Hole works on the Raspberry Pi OS along with other Linux distros, and you can learn more here. The downside of using the Pi Zero 2 W is that its WiFi range isn’t very long. YouTube app on a smartphone).īuilding a PiHole fulfills a few parameters, including that you can’t use a microcontroller, WiFi is necessary and the Pi Zero 2 is one of the cheapest computers you can get.Īn additional benefit is that it’s so small you can probably just place it where your router is. It’s more effective than a browser extension like uBlock because you don’t have to set it up on every computer, and you can also block ads in apps (e.g. PiHole is an ad blocker which filters traffic between a device and the router. Pi Zero 2 W and Pi-Hole ad filter Pi-Hole dashboard ( public domain image) If you plan to build a device that runs on a battery, needs to fit in a small space, or needs to run Linux, then the Raspberry Pi Zero 2 is the perfect device. Power drain must be kept as low as possible.Microcomputer must be small and/or light.Microcontrollers like Arduinos aren’t adequate.The Pi Zero 2 W is best suited to applications that have these parameters: If you are looking for fun projects to do, check out this post.
