From washing machines to CNC axes the PID control is a fundamental part of all controlled systems. The Proportional Integral Derivative provides tight control loop and stability.
In this video you will learn why we do use PID controls, what they are and how they works.
Also as a bonus you will see a conceptual electronic schematic of a possible implementation of a #PID control.

![How to spot a fault in a circuit, like a pro : hands on electronics [1]](https://i.ytimg.com/vi/ye9dguKy_Cs/mqdefault.jpg "How to spot a fault in a circuit, like a pro : hands on electronics [1]
In this video I show the method to find out a fault on an electronic circuit board. In the specific case we have an ESC (Electronic Speed Control) that is used to control a washing machine motor (used to drive the spindle of a lathe) and somewhere in the circuit there is a faulty contact. It turns out it was a bad soldering that caused an uncertain contact, making the motor to start and stop randomly. The video shows the procedure to spot the exact point where the fault is present.
Wonder how to #faultfinding without schematic? Watch this video too: https://youtu.be/yjxuMwLN7zI

![The mindblowing #photoacoustic effect: #light makes materials to play #sound! - [Redone video]](https://i.ytimg.com/vi/zIQXlf1qLsM/mqdefault.jpg "The mindblowing #photoacoustic effect: #light makes materials to play #sound! - [Redone video]
A piece of fleece generates sound just projecting a modulated light! No electronics involved! (Aside the light modulator.)
*This plays sound JUST with light!*
I reproduced an experiment that led to the definition of the photoacoustic effect. This effect has been first discovered by Alexander Graham Bell, the inventor of the telephone and of the photophone. While this effect is widely exploited in photoacoustic spectroscopy, it is often overlooked by many.
So with this video I bring it to light ...so to say :-)
After a first failure in reproducing the experiment, after some research I managed to achieve results.
Encouraged, I developed a special #LED driver. The final result is amazing: a simple piece of fleece emits #music just for the radiated modulated light!
The effect is regarded to be caused by light induced thermal expansion and contraction of materials.
In doing this experiment I also stumbled upon a weird response from a piezoelectric sensor, with an unexpected and interesting effect that I showcased in a bonus extra section of the video.
