murphle posted:The standard matters if you're trying to push data over the cable. It's way less of a concern if you're just trying to get 5V up to a camera or GPS. Voltage drop is still a concern. Assuming a good quality cable with 24AWG copper conductors, 15 feet long, and 5.5 volts (the specification maximum) at the source, and a 1A draw, you'll see 4.73 volts at the far end. That's low, but within the expected range that USB devices are supposed to handle. However, use a cheaper cable with 28AWG wires and a linear regulator putting out exactly 5 volts at the source, and your device will see 3.05 volts -- not even enough to power up a low-power microcontroller.

Random question: I've heard that in California, recording audio of someone without informing them beforehand is illegal wiretapping, so any secret recordings you make are inadmissible as evidence. This rule doesn't apply to video, just audio. Does this mean that if your dashcam records audio, the recordings won't be valid in court?

Well, I ride a motorcycle, so the camera is on my helmet...and I can imagine that if I got into any incidents, there'd be words exchanged. Would a lawyer be able to argue that because I recorded the person screaming at me without their consent, the evidence is inadmissible on a technicality? Does being out on a public highway excuse the requirement? Would drawing the person's attention to the camera change anything?

Cartoon posted:I wouldn't have bother but I had to do it (The whole cam download/Youtube upload) for the next video and it happenned today too. Some further evidence of the "gently caress you I'm in a Truck!" attitude: I think the title of this video is supposed to be sarcastic, but actually it's just accurate. What did you want the truck to do? Slam on the brakes and lock up the wheels and slide into a tree, just because you feel uncomfortable pulling a little bit onto the shoulder of a narrow forest road? e: I watched your second video too and you are just a whiny peepants baby. That guy made a perfectly legal and safe merge into your lane and it pissed you off because...??? Heavy equipment and vehicles with trailers don't have to get out of your way. Get over it. e2: nice illegal pass around the trailer (you drove over the parking space lines, moron) because you can't wait five seconds for him to make the turn. The "loving asswipe" is you.

Cartoon posted:Well in my defence the fact that it was a blind corner may have tipped you off to the fact that they did a U-Turn across double center lines. If I had been in a heavy vehicle I may not have had time to slow down enough to avoid them. They should have taken the slightly longer route to their destination that didn't involve a dangerous illegal turn. 1. Can you post a Google Maps link to that particular intersection? Because I don't think what he did qualifies as a U-turn and I'd like to check it out for myself. 2. If you are in ANY vehicle, not just a heavy vehicle, and you are driving so fast around a blind turn that you wouldn't be able to stop in time for the sudden appearance of another vehicle, a boulder, a pedestrian, etc., you are a dangerous driver and should be kept off the roads.

Interstate highways are a slightly different situation because they're controlled-access and heavily patrolled. The chances of coming across a kid chasing a ball or a boulder that hasn't been cleaned up are pretty minimal. However, they still shouldn't be designed to include blind curves of such a radius that the average vehicle travelling at the average speed couldn't stop in the available visual distance. And the fact that interstates regularly produce multi-car collisions where drivers are unable to stop in time is proof that they're still problematic. On any other road, you're a goddamned moron if you outdrive your braking distance. It doesn't matter if you know the road like the back of your hand and you can totally take this curve at 55 even though it's marked 20. If you can't see as far ahead as it'll take you to stop, you've just turned the first unexpected obstacle into an inevitable accident. Ask me how I know! e: just for the record, though, I did once come over a hill on I-280 to see a loving aluminum ladder sitting in my (the rightmost) lane. I braked heavily and veered onto the shoulder in case someone was tailgating and zoned out, but if I'd been going much faster that may not have been an option. There's no way to prepare for those situations other than driving at a reasonable speed for the road. Sagebrush fucked around with this message at 07:14 on Mar 1, 2016 |

sharkytm posted:Hey, I get to contribute. This is what you call "close on the light?"  By stepping through it, I can tell that he started to move into the intersection as soon as your light turned yellow -- with the set-back stop line, it looks like he was timing it so that his nose would enter your lane at the moment he got the green. So yeah he jumped the gun but you were 100% in the wrong there. The collision would have taken place when his direction was green and yours was red, and the camera shows that you ran the light.

The thing that makes me the most irrationally angry is when, as I'm changing lanes, I put on my turn signal, wait for an opening, check my blind spot, slide over into the space, and get immediately honked at by the person I moved in front of because they weren't paying any attention to the road or my signal and they think I cut them off. Or alternately they saw the signal just fine, and were accelerating to try it and close the gap specifically so I can't take it. Either way, the sheer audacity of the pricks who do that just drives me insane It's nearly always someone in a BMW or Lexus SUV, for some reason

Sure it is. (Nearly) all quartz clocks use a standardized 32.768 KHz timing crystal whose frequency is electronically divided in half 15 times to get a 1-second pulse. One way to cut costs in your mega bargain dashcam is to buy your timing crystals from the factory reject pile, because 32.783 KHz is close enough, right? Who's gonna notice anyway?

Yes, probably. 2 minutes in 8 months is roughly 6 parts per million, which is right what you'd expect for a generic quartz timing crystal (most of those I've seen are specced +/- 20ppm or so). Crystals also expand and contract slightly with temperature, which alters their frequency even more, so if you live in a particularly hot part of the world you might find that your marginally larger crystal beats just a little slower and your clock loses time a bit more rapidly. In general the crystals are trimmed for the median temperature in the sort of places humans usually inhabit, though, so the annual weather changes will mostly average out.

^^^^ neat, I did not know that. What's the reason? Do they cut high-frequency crystals into different shapes from low-frequency ones? Anyway, point is that if you're buying your electronics from random mystery Chinese sellers on AliExpress or Amazon or eBay, I absolutely expect that they are using the cheapest possible components, including Z-bin timing crystals that won't hold 10 minutes in a month. Or they're just leaving the crystal out entirely and relying on an on-chip resonator or whatever that is even less accurate. Watch some of the EEVBlog or BigClive videos of cheapo AE/DealExtreme/Banggood product teardowns if you really want to blow your mind.

If you're really into it, you can assume that your crystal is pretty average, get some datasheets from digi-key for generic timing crystals that have t/f graphs like those posted above, find their reference temperature, compare that to your average annual temperature, and see how well the graph lines up with your observations. I am working on building a digital instrument cluster for my motorcycle, and in the current version I took some shortcuts with the timing system, and it's fairly cool to see how my speedometer accuracy changes quite dramatically with the outside air temperature (as the timing system that's measuring the wheel revolutions speeds up and slows down).

I have heard that in Australia you'll also get ticketed for going even 1 km/h over the limit; the police attitude is "it's a speed LIMIT not a speed SUGGESTION" and you are supposed to be going 5-10 km/h slower than that.

Does that also mean that if you turn it on while cruising at 75mph, and it slows down to 35mph for heavy traffic, that when you disable it to take manual control it'll floor it back up to 75 and ram the car in front?
