This week, I switched to a different telecommunications provider, which led to a dynamic public IP address. Consequently, in today’s blog post, I will discuss the implementation of CloudFlare DNS Service as a Dynamic DNS provider. This configuration ensures that services hosted on the home network remain accessible to remote users through a stable and automatically updated domain name.
Today I will share my journey of preparing a working environment to develop Rust for Espressif boards. Discover how I made the decision to work with Rust for embedded systems, a language known for its safety, speed, and reliability. I’ll also guide you through the process of preparing your development environment, like installing necessary tools, and configuring your workspace to program Rust in VS Code using Docker Dev Containers.
PocketBase is an open source Go backend that features an embedded database and an admin dashboard UI. As part of this project, I developed an app to manage a piggy bank associated with the sale of products. With this app the users can register how many products they bought and also register the amount they left (charge) in the piggy bank by indicating the amount and taking a photo as proof.
Have you ever wanted to control or configure an Arduino board using a user-friendly graphical interface? In this blog post, I will explain how to build a GUI with Electron (a popular framework for building cross-platform desktop applications) and Vue. With this application, you’ll be able to list Serial Devices and easily send data to an Arduino with a click of a button.
In today’s digital age, many of us have smart devices or applications at home, but how can we access them from anywhere in the world without exposing them to potential threats? The answer is: with a VPN! A home VPN not only provides a secure and encrypted connection, but also allows us to access our home network, files, and devices remotely. In this blog post, I will share my home VPN setup and also explain how to use a DNS server to identify devices and applications using domain names instead of IP addresses.
Let’s assume that we have a lot of sensors publishing structured data to an MQTT broker and we want to store this data in a database. A simple way to do that is to use Telegraf (tool from InfluxData) to consume and process the data and store it in an InfluxDB database. In this tutorial, I will explain how to prepare this setup using docker-compose.
This post is complementary to the previous post of Redis TimeSeries, in which I explained the benefits of using Redis to store time series data. In comparison, instead of using Grafana to plot the data directly from Redis I will explore using gRPC-web to establish a connection between the backend written in Go and the frontend application written in Vue.
