Running OpenWebRX on balena to remotely monitor local radio spectrum

Combine a Raspberry Pi and an inexpensive SDR (Software-Defined Radio) dongle to create a remote monitoring device that you can place anywhere in the world (with internet access) to view the surrounding radio spectrum and stream audio from some of the detected signals. It hosts a small web server which

Two projects, one device: turn your Raspberry Pi into a multitool!

Built one of our projects, and want to expand upon it? Perhaps you want to build a second one, but lack the hardware? Fear not! One of the great benefits of balenaCloud is that you can combine different projects and run everything on one device. In this short guide, we’

Build a Raspberry Pi powered live train station sign for your desk

Build your own UK train station platform departure display (next train indicator) with live data using a Raspberry Pi Zero, OLED display and 3D printed case - a cool (and practical!) desktop gadget. It involves a bit of software, a bit of soldering, and some 3D printing too. Contents Introduction

Build a smart photo slideshow with balenaCloud

When we started the balenaDash project, the main goal was to make it easy and straightforward to deploy IoT devices that display information on a screen. The project has been constantly developed, with new features such as automate the backlight timer, how to setup a dashboard or even displaying google

Aggregate data from a fleet of sensors with balenaSense and InfluxDB

Back in March we wrote about balenaSense, our project to monitor air quality with a Raspberry Pi, Grafana and InfluxDB. Lots of you have been using this project and giving great feedback, and one of the requested features was the ability to take data from multiple balenaSense devices and bring

Bring a dummy security camera to life, using a Raspberry Pi and WebRTC

A few weeks ago we released a project called balena Cam where @mbalamat developed an application running on balenaOS that initiates a WebRTC video streaming connection between the server (a Raspberry Pi, for example) and the client. You can check the full blog post here. Once the main core of

It's a sign: build a remote controlled digital display with Screenly OSE and Raspberry Pi

Try this project to get up and running with a display you can control remotely to display photos, videos, dashboards, web pages, and digital signage. This tutorial was put together by the friendly folks at Screenly. They've recently updated their open-source digital signage software project to work seamlessly with the

Deploy a fleet of environmental sensors with balena & InfluxDB

Last month Alex Markessinis released a very nice project based on balenaSense to manage the temperature and humidity of a data center and upload the data to an external InfluxDB database. Follow along as we go through the process of setting up this project to capture data from remote sensors

Monitoring the edge with Prometheus pt. 1

A method of self-similar monitoring for the edge. Properly monitoring a fleet of devices is an evolving art. One of the current leaders in the server world for application and hardware monitoring is Prometheus, both for bare metal and as a first-class citizen in the Kubernetes world. In order to
