“In this project, I’d like to share how to build a 2-axis thermocol/ polystyrene cutting CNC machine with its frame and supports made of electrical wire casing/duct and 3D printed parts. Basically it is a thermocol cutting tool …
“Looking to learn how to build a compact size LED matrix for Arduino? then this article is what you are looking for. Today, I’m thrilled to guide you through the steps to create your very own 32x8 compact LED …
“This is a very simple, easy to make, visually effective, and self-contained device intended for both beginners and more advanced DIYers. Ultrasonic sonar is devices that use sound waves with frequencies higher than the upper audible limit of human hearing …
“Simple and inexpensive way to make such an instrument, with which we can measure resistances with a resolution of 1 milliohm. In practice, we very often need to measure low resistances. Measuring low-value resistances, especially those less than 1 ohm …
“Today, I’d like to share how to build a fixed belt CNC plotterthat has a very different construction from the others, in that both axes XY are made from fixed timing belts and their stepper motors are hidden inside …
“This is the stand-alone capacitance meter that you can make using only two electronic components. The capacity measurement option is usually only available in more expensive multimeters, so it is desirable to make such an instrument ourselves, especially if it …
“Blitz-O-shield: Arduino Nano shield for thunderstorms and the (usually) associated lightning detection I’ve always been fascinated by thunderstorms and the (usually) associated lightning. So it would be good to know in advance whether a thunderstorm is approaching, wouldn’t …
“The PID Temperature Control of a miniature thermal chamber is a system designed for teaching the fundamentals of Process Control. Story The PID Temperature Control of a miniature thermal chamber is a system designed for educational purposes. It can be …
“This is an extremely simple, but still visually very effective project, and can serve as a gadget on your desktop The spectrum analyzer displays the amplitude of signals as a function of frequency, allowing engineers and technicians to visualize and …
“I am pushing the limits of how much compute you can get out of an Arduino Nano: - 320x200 pixels of monochrome VGA output (optional: 16 row colors) - PS/2 keyboard readout - requires only 1(!) logic IC 74HC166”
