When new flagship telephones come out, CNET does not shrink back from testing the sturdiness claims made by producers. We have completed drop assessments. We have completed water assessments. When the brand new foldable telephones began coming in the marketplace from Motorola and Samsung, we even did folding assessments.

Even earlier than the newest Samsung foldables had been introduced, I would been attempting to determine a brand new form of experiment to gauge the resilience of those telephones. May we check the energy of the hinges with weights? Perhaps use it as a shovel on the seashore to see if any sand bought inside?

With the introduction of the Galaxy Z Fold 3 and its accompanying S Pen Fold Version, I made a decision we should always have a look at the sturdiness of the display itself. I used to be curious to learn how a lot one might draw on the display with the S Pen earlier than any in poor health results may very well be seen.

I knew randomly drawing on the display for an prolonged time frame was no approach to conduct the experiment, so I turned to my 3D printer, which I knew was able to producing constant repetitive motions. I modified my Creality Ender 3 V2 printer to make it a plotter as an alternative and printed out a holder to make it work with the S Pen.

Then, with just a little assist from the web, I needed to educate myself tips on how to program just a little little bit of gcode so I might make the plotter do what I wanted it to. The important thing ended up being this little string proper right here: G2 F5277 I50 J0. With some trial and error, I found out this little bit of code would draw a circle with a radius of 50mm 1,000 instances in a single hour. Copy and paste 1,000 instances in Notepad and voila!

Lastly, as soon as I bought the Z Fold 3 in hand, I needed to discover a good drawing program that might be attention-grabbing to observe for 16 hours. I landed on Infinite Painter due to its clear interface and large provide of attention-grabbing brushes.

So, now the time has come for me to see what occurs after I put all these items collectively and run my experiment. You may notice that I preserve calling it an experiment, and never a check, as a result of there’s nothing actually scientific about what I am doing. Samsung hasn’t made any claims about how a lot you’ll be able to draw on the display of the Z Fold 3 with the S Pen, so I am probably not testing something. I am simply presenting an illustration of what would possibly occur if somebody, for some purpose, selected to attract circles on the Fold 3 for the equal of a 5K race.

Hopefully, it should additionally present some zen to your day, having this experiment simply operating alongside within the background.

So tune in on Wednesday at 1 p.m. PT to see me kick issues off and preserve coming again till the wee hours of Thursday morning as I method my purpose of 16,000 circles, or simply over 5,000 meters of drawing.

And should you’re curious, this is a few of the math behind my insanity:

Radius of circle being drawn: 50 mm

Circumference of circle: 314.16 mm

The machine attracts 1000 circles in 1 hour

1000 circles x 314.16 mm = 314160 mm/hr = 314.16 meters per hour

5 km would take 15.9 or principally 16 Hours

314.16 meters per hour = 1030.7 ft per hour

1 mile = 5.12 hours

3 miles would take 15.36 hours

5 km = 3.1 miles


Now taking part in:

Galaxy Z Fold 3 is an acquired style that I now crave
