Robot Punchers with Arduino
James Bruton is well-known for his (often eccentric) inventions, which he regularly documents on his channels. In this video, he demonstrates how he has created remote-controlled rovers that engage in punches. 🙂

A minimal 3D-printed scale
A load cell is a sensor designed to measure the weight of an object. Essentially, it is an aluminum bar containing 4 resistive strain gauges that are measured through a Wheatstone bridge to detect the weight of the object. In this project, using a small Microchip ATtiny1614 and a 5kg load cell, a 3D-printed scale…

Expanding the pins of a microcontroller
What to do when the chosen microcontroller doesn’t have enough pins? We will find out in this tutorial, where we will learn how to use shift registers to control LEDs and read buttons with just three wires! In six steps, we will use the CD4094 and CD4021 with a PIC microcontroller.

SDS011 the Air Quality Sensor
Measure the quality of the air around us using a laser technology sensor that can quantify the concentration of the infamous micro-dust. Air pollution, and in particular the presence, quantification and concentration of so-called ‘fine dust’, is a very topical problem, especially in large urban agglomerations and near the large industrial areas bordering large cities….

NIXIE STYLE LED DISPLAY
We pick up the fascinating Nixie tubes through displays based on packages of laser-engraved plexiglass plates, illuminated by Neopixel LEDs. For those born in the era of solid-state displays, be they LED, 7-segment, dot-matrix, or even liquid crystal, it is difficult to imagine how text and numbers were displayed before their advent; Well, those who…

Water Softener Salt Level Monitor
Water softeners work using a process called ion exchange in which calcium and magnesium ions from hard water are exchanged with sodium chloride (salt) via a special resin. The water goes into a pressure vessel where it moves through the resin beads, and the calcium and magnesium are replaced by sodium. The resin beads will…

Sparkly Air Sensor
I wanted to please a friend, an environmentally conscious friend who is concerned about mould spores in the air (from damp), additionally he is an occasional smoker and lives on a fairly popular city road, so he’s keen to see what’s present in the air as far as concentration and air quality go. To…
