Back in the time when I was building my Arduino based Ludwik Drone I faced a problem of choosing proper motors and propellers. I didn’t know anything about drones at that time so I had to trust motor manufacturer and the datasheet of a motor those are most likely to be a good source of …
For this project, I wanted to create a winch that would be functional for use in a show in a theatre. Often, we have to fly in and out small objects, like chandeliers. This unit would be ideal for raising and lowering small objects in spaces that did not have a fly system, or for …
Story Fascinated by this humorous anthropomorphic idea on instructable that left me philosophizing deeply about the essence of art, I decided to make this a project after witnessing many ruthless battles between human and robot on YouTube. How does it work? The Arduino “listens” to the state of the switch and actuates the servo when …
Stepper motors are not smooth – they move in “steps”. Different motors have a different number of steps to make one complete rotation. You use software to step the motor forward or backward at different speeds. There are two kinds of stepper motor bipolar and unipolar – Unipolar will have five or six cables coming from them. Bipolar will …
Let’s get the math over right off the bat. There are a LOT of attempts to describe how Ohm’s Law works, each one nerdier than the last. Here’ one I like. Warning: SFWBN (safe for work but nerdy). V = voltage measured in volts – the difference in electrical potential. I = Current measured in …
Arduino Laser Turret, Overview: In this project, I will demonstrate how to create an Arduino laser turret using servo motors and a two-axis joystick. I will provide the necessary code and a circuit diagram, accompanied by a detailed explanation of the project. This will enable anyone to successfully build the laser turret without encountering any …

This Instructable shows you how to build a micro-controller based weather monitoring device. Built on the Arduino Uno board it can easily be extended and modified should you have additional sensors at hand. Main requirements: – Measure temperature (accuracy +/- 0,5 degree Kelvin) – Measure barometric air pressure (+/- 0,1 Pascal) – Display measured values …
Precise measurement of line signal frequency is very important in many applications, especially in the management of power grid systems. Tasks like calibration of governors of engines that run generators in power plants need a resolution up to 0.01Hz. Frequency is also an important parameter in load sharing among several power plants in the grid. …

This project describes how to make a low-cost DC power meter that can be used for displaying Voltage, current, power and the running time of operation. This is useful and can be used as the display for your bench power supply too. This can be used in the display section of a 0-55 v battery …

Heating things up is one of the most performed tasks in a lab. Quite a lot of times it is not enough to simply hold something at a certain temperature, but the rate at which something is heated and for how long is just as important. Especially when you try to develop catalysts for chemical …
