OctoPrint® is a great solution for controlling your 3D printer. However, it’s missing one key function. You can’t turn the 3D printer on and off. Now that we have setup our OctoPrint® Server for multiple printers we are going to add this hardware and software feature. Hardware I assume you already have your OctoPrint® Server […]

In this post, we’ll be taking a closer look at the ESP32-S2 hardware, and more specifically, the ESP32-S2 Mini pinout. The ESP32-S2 is based on the Xtensa® single-core 32-bit LX7 microprocessor, up to 240 MHz. The ESP32-S2 pinout consists of 43 × programmable GPIO’s pins, 2 × 12-bit SAR ADCs, up to 20 channels. The
As great as Octoprint® is, there are some limitations. Plus, while Raspberry Pi’s are cheap, they quickly add up in cost — memory cards, power supplies, enclosures, and even outlets in power strips and ports in network switches all add up. I started looking at how to run multiple Prusa printers on a single Pi

The upload procedure for ESP32 boards is a little different from a standard Arduino procedure. Most Arduino’s will automatically reset when a new program is being uploaded, and will automatically enter programming mode. On some ESP boards you have to manually enter programming mode, and on the bare-bones modules, you even have to reset them

Recently I received a package in my mailbox. When I looked, I was surprised to see that it was sent by my friend Johann Zita. He’s added some cool features to his great OMNIFIXO – M4.2. And I would like to share this with you. There are many things in this world that are super
A thermocouple is a device for measuring temperature. It comprises two dissimilar metallic wires joined together to form a junction. When the junction is heated or cooled, a small voltage is generated in the electrical circuit of the thermocouple which can be measured, and this corresponds to temperature. Basics of Thermocouples A thermocouple consists of
A PID controller or controller is a very advanced electronic thermostat that ensures that the temperature, for example of an oven or proofing cabinet, reaches and retains the set temperature very accurately (and as quickly as possible). PID controller PID stands for Proportionally Integrating and Differentiating. A PID controller is a very advanced thermostat (temperature controller). A
Since I started my ESP8266 – HomeKit Blinds project, I’ve tried all different kind of soldering techniques to improve my production speed whilst maintaining the quality. And although I found out a hot air soldering really makes life a lot easier, applying solder paste is a bit of a time-consuming work. To make life a

What is PCB solder paste? PCB solder paste is a powdered mixture of flux and solder. It is used to attach thousands of tiny electrical components to their contact pads in the assembly of printed circuit boards. Without it, the process of PCB assembly is incomplete. If you’re looking forward to designing and fabricating a PCB, read this article. It

Thread is a new, energy-efficient networking technology found on the HomePod mini and Apple TV 4K (2021). Products from Nanoleaf, Eve and other manufacturers have also increasingly been made suitable for thread. What is it, and what can you do with it? You can read that here. What is Thread? Thread is an IP-based network
