Zener diodes are a special type of semiconductor diode devices that allow current to flow in only one direction and also allow current to flow in the opposite direction, but only when exposed to sufficient voltage. And while that sounds a bit esoteric, they’re actually some of the most useful components to ever cross an […]
Since Espressif Systems arrived in our collective consciousness, they have expanded their range from the ESP8266 to the ESP32, and going beyond the original WROOM and WROVER modules to a range of further ESP32 products. There’s a single-core variant and one that packs a RISC-V core in place of the Tensilica one, and now they’ve
In this blog, we will discuss how to use the ESP32 touch sensors and how to use the esp32 touch sensors as a push button without having to connect an external push button. The ESP32 chip offers ten touch sensors. These touch sensors are built-in with ESP32 chip and are capacitive type. These touch sensors

As my Octoprint® Project extends, It’s time to give my Raspberry Pi®, that’s functioning as OctoPrint server with PSU control, a proper Enclosure. The goal is to make a casing that feels and looks like a complete product, simplifying installation and eliminating clutter. So at first I took the dimensions from the hardware that’s needed to run my OctoPrint

Octoprint® is quickly becoming the best way to drive many types of machines. Including CNC and lasers mills that use the common 3D printer controllers. I have one 3D printer and one CNC machine. In my previous blog, I explained how to control multiple printer’s trough Octoprint. Now I will explain how to convert one
