If you have a question, ask it. And don't be lazy.

one observation which seemingly contradicts these: in the dark, when you move a bright object together with a darker object, the darker object appears to lag behind. i noticed this for like a phone screen vs. the charger's plug does it seem as if the object lagging behind is doing so because its im...

very cool, probably the first time this info has been made public, or has even been measured.

Ah, you're right. I was thinking of a mixture distribution, where each trial expresses only one of the underlying phenomena. In this case, however, each trial is the result of multiple phenomena.

Awesome stuff :) Looks like a mixed distribution (uniform + skewed normal). I'm assuming the uniform component is due to the USB polling (min: 0 us, max: 1000 us). Any guesses about what's responsible for the skewed normal? Also, do we know anything about the amount of time it takes for the digital ...

god is on your side

measuring voltage requires analog-to-digital conversion and probably i'd need a faster chip to read an adc at >1MHz it's unnecessarily complicated for minimal improvement Fair enough :) At the very least, you could measure the average time it takes for diode to reach its threshold voltage, by looki...

On a tangential note, I took a look at the blur trail test on my CRT and when I focused on my stationary cursor in the middle of the screen I was able to notice that my eye's persistence is significantly higher at the center of my vision than at the edge. Basically, I saw vertical lines as the test...

oh, i'm not choosing anything the atmega32u4 has a threshold voltage for its gpio pins. for instance if the voltage goes above 1.5V or so it's considered 1, if it goes below 1.4V or so it's considered 0. don't remember the exact numbers, but the datasheet has them And I assume that the percentage o...
