Update: there was some confusion when I made this video. I ordered the G2 model but when it arrived I couldn’t find any G2 branding on my device so I mistakenly thought I had been sent a G1 instead. In fact I had not. I did in fact receive a G2, it’s just that the G2 branding was very subtle and I missed it. The only indication seems to be a small “G2” on the back under the HP logo. Also I heard that the G2 model came with a USB-C connection, but that is wrong. My G2 has a USB-Micro connection, which I believe is standard.

Silly Job Title: Digital Dancer. I am the Digital Dancer!

In this video we unbox the Sharp EL-506TS scientific calculator. In this video I also mention about my Casio fx-991CW and my Sharp EL-546L.

The constants used in the calculator are taken from CODATA Recommended Values of the Fundamental Physical Constants: 2018 which is an impressive scholarly work.

I am sorry for the poor focus and zooming in this video. I have ordered a new camera which should help me to minimize issues like this in future videos.
