Headstock alignment is a critical point in every lathe, in this video I show how I've done it for my home made benchtop precision mini lathe.
Before going through the actual installation I've performed some simulations of the whole process. The headstock is installed using leveling paste that allows only small corrections once it is set. The headstock is equipped with compressing and expanding screws to let adjustments over the vertical plane and lateral screws to let adjustments over the horizontal plane.
DISCLAIMER: In the video some items show their brand because due to limitations of my editing skills I was unable to remove them. So I clarify here that there are NO SPONSORSHIPS, I DO NOT ENDORSE NOR DISAPPROVE THOSE BRANDS THAT ARE INCIDENTALLY VISIBLE IN THE VIDEO. Products are visible in the video because they are necessary for the purpose of the work shown and because I found them fitting my personal purposes, not because sponsorship or paid placement. In future videos I will try to overlay a message that clarify this point when brands appear too prominently.
Video is composed by the following sections:
0:00 Intro; 1:00 simulations; 1:42 the problem of test bar deflection; 3:40 ball-tip dial indicator may lead to erroneous readings; 4:54 counterweighting; 6:20 preparing leveling paste; 7:28 headstock installation; 8:02 alignment operations; 12:30 double check with a square and final considerations.

![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]
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.
Remark: This video has been redone because of missing content and technical issues in the originally posted video.
