That too because lord knows what happens when the tape falls off my optical to rca adapter. Why this thing has a Batman spotlight built into it, I'll never know.

Funny you should mention rechargeable batteries. A while back, 14 years or so ago, I was dabbling with electronics and wanted to swap my xbox360 controller and front panel led's from Green to something else, like purple. I ordered a bunch of purples, blues, reds, etc. I wire up the purples to the controller. Nothing. And these were so small, if the soldering iron stayed on it for more than 2 seconds it literally would disappear in a puff of smoke.
Apparently I'm telling this out of order but it helps. I did the red ring on the 360 front panel with the purples fine, so I know theyre good. I replace the purples with blues and it lights right up. I put purple back, no dice. I'm fiddling around and I forget how but I plug the charging wire into the controller direct and I get flashbanged by purple lights. Similar to your story I found out the rechargables had less voltage. So the red ring front panel is hardwired and getting full juice, but wireless, no dice. Pop in the usb charger and yeah it would light up. Also confirmed regular AA's would work, but I already had all these battery packs so I wanted to stay with the lower voltage.
So I opted for a blue/red/blue/red X pattern and left the purples for the front panel. Cool side effect was that as the batteries died the blue led's would get dimmer and dimmer until you just had 2 bright red led's and then the controller would just die. I think this may be a reason they favor red for emergency systems as it seems to require less power.

Reply to comment by angsan_F in ELI5 Why do asian people smoke so much? by [deleted]
Anecdotal but I had a friend who smoked back in Junior High School. We asked why? He said it was cultural and his father encouraged him to do so. There was a belief smoking was masculine and if you didn't you may be perceived as homosexual.

Reply to TIL Why Dog Paws Smell Like Fritos. Even the cleanest, healthiest pooch has trillions of bacteria and fungi living on their skin. That yeasty, corn chip smell is actually a normal byproduct of harmless bacteria, usually Proteus or Pseudomonas, both of which are naturally present in our environment. by Rossknight65
So Frito smelling socks aren't THAT bad... I'll let the wife know.

Reply to ELI5: Why can we see differences between 60, 144, 165 and 240hz if the eye only can process 60fps? by Xyraph
We most assuredly can. As a gamer 30fps games can be problematic for me, causing motion sickness and nausea, if theres a lot of action and camera movement. Slower strategy games are fine. 60 fps I can tolerate decently, but may have some issues with fast camera spinning, but typically no nausea. 90fps is where I can spin the camera a lot more without worry of side effects. 120 and I can spin it like crazy and still keep track of targets, read a sign while driving a car in game, etc.
There was an article that fighter jet pilots can see changes around 200hz.
https://www.testufo.com/ is a good comparison to see at least 30 vs 60 as you most likely have a 60hz monitor. Some phones now support 144hz so you may have one and can check there to see the difference.

Reply to comment by Chelzor in TIL the way NYC has bodegas, Australia has milk bars. Modeled initially on American soda fountains, they’ve been on the decline since the 70s due to competition from supermarkets by idiomaddict
Bodega are just mini convenience stores. Basic products, not much variety. A few soda options, diapers, cold cuts, snacks, illegal antibiotics and what not.
