How to make factory machine hard disk drive more durable? How much its estimate life span?

Quite likely, the SSD killer is electrical. We can't entirely rule out mechanical vibration, but SSDs are pretty robust mechanically. A simple rubber mounting would increase the resiliency even ...

How to make factory machine hard disk drive more durable? How much its estimate life span?

First off, electrical and magnetic problems are not as bad as problems of vibrations and air contamination. Moisture in air plus dust or chemicals can corrode or short paths quite easily, and in our ...

How is "16.7 million colors" in a display calculated?

Each color red, green, blue that makes a pixel has a range of 0 to 255. So each of the colors has 256 possible settings. 256*256*256=16.77 million possible colors.

How to make factory machine hard disk drive more durable? How much its estimate life span?

Estimated lifespan is given by the manufacturer usually as "MTBF = 2000hrs" but in "normal conditions" - what you describe is not normal. Why are the SSD drives failing - physical damage or poor ...

Is using your mouth and lungs to blow away dust inside your computer somehow bad for the computer?

Another option would be to use a vacuum cleaner, that way any dirt is not pushed inside the computer but its pulled outside.

What is the proper way to get Arduino to "push" a button for me on a separate circuit?

To get as close to the voltage of the battery as possible, consider using a single-pole, double-throw relay to reroute power straight from the battery. Here's a possible schematic where the Arduino ...
