Internet users sometimes find that they cannot open some foreign sites. The most common reason for this is that websites in your country are blocked. People living in another country can access that site without any problem. This problem has a simple solution: a VPN extension for your browser. Let’s talk about these mini programs …

Low energy consumption is one of the major triggers of scalable product launch and maintenance. When your product is power-hungry, you are bound to receive negative reviews from your customers or get your app deleted altogether. So every developer wants to achieve long battery life of their products; developers are increasingly looking for ways to …

At the place I work, we use xymon to monitor of our servers. All of the services monitored are important, but we wanted a separate indicator to simply show the overall health of the most critical systems. Furthermore, we came up with the following criteria: We wanted this visible to everyone whether or not they …
This utility GUI application is a tool for visualizing the content of multiple data streams passed as short numeric messages back and forth across the network via a MQTT server. It supports opening an authenticated connection to the server, subscribing to a class of messages in order to receive them, viewing message traffic, and plotting …
This utility GUI application is a tool for debugging programs using a remote MQTT server. It can show messages on multiple topics and publish text-based messages on a single topic. The application is provided all in one file and can be be directly downloaded from qt_mqtt_monitor.py. The following sections have both documentation and the full code. …
This GUI application connects an Arduino sketch to a remote MQTT server over the network. It communicates with the Arduino using the serial port, relaying lines of text to and from the MQTT server. This can be used as a platform for remote Arduino to Arduino collaboration. The application is provided all in one file and can …
This sketch demonstrates Internet-based remote communication using a companion ‘bridge’ program running on the attached host which sends and receives messages via an online MQTT server. This allows connecting one Arduino to another over arbitrary distances, which we can use as a starting point for building collaborative telepresence. This example is configured to provide for …

This sketch is an Arduino program which acts as an simplified hardware I/O server using a simple readable message protocol. The intent is to provide an easily modified and extended real-time embedded hardware controller which can interface easily with a non-real-time client running on a laptop or Raspberry Pi. The following documentation was extracted from …
Constructing your very own IoT weather monitoring station can be a complicated ordeal, as getting values from the embedded device to some kind of web server in a secure manner takes a lot of effort and time to complete. For his system, Clem Mayer from element14 Presents was able to use a MKR WiFi 1010 that sends relevant …

Most readers of Hackaday will be well aware of the current shortages of semiconductors and especially GPUs. Whether you’re planning to build a state-of-the art gaming PC, a mining rig to convert your kilowatt-hours into cryptocoins, or are simply experimenting with machine-learning AI, you should be prepared to shell out quite a bit more money …

Machine learning is an incredible tool for conservation research, especially for scenarios like long term observation, and sifting through massive amounts of data. While the average Hackaday reader might not be able to take part in data gathering in an isolated wilderness somewhere, we are all surrounded by bird life. Using an Arduino Nano 33 …
