1977 Blackjack and Calculator Diagnosis
 
29:48
I got a Unisonic 21 untested and it turned out to need some work. Time to figure out what's wrong. This is a fairly anticlimactic video. It ended up "working" in the end but I didn't really do anything. I did notice it did actually very faintly turn on in the beginning, I still don't know why it got brighter over time. Yes I could buy the capacitors, but it doesn't make sense to place an order for just this device. Although I may do that in the future with an online order if I piggy back it onto something else. About the back filming surface, after a test video I decided to record a complete video using the underside of my ESD mat. Here is the test video: https://www.youtube.com/watch?v=1XoyG6w6FJo The blue reflects a lot of light onto the subject and into the camera during macro shots. A darker mat would give a noticeably better image quality. But the black is too dark. It didn't work well for this video. I will be going back to the blue side until I get something else that works better.

Gender Neutral Pronouns: They're Here, Get Used To Them

http://tomscott.com - @tomscott - Grammatical gender is a silly concept.

[The line about "the first sentence of the video" is wrong: it's not actually in the first sentence of the video. I cut that line, and forgot about that second line. Whoops.]

Mac or PC? - Computerphile
