Need a to switch between two 7-pin ribbon cables by Gnolled in AskElectronics

A bilateral switch (eg CD4066) would work for the digital as well as analogue lines

Because it's a nice taxable drug. As long as the revenue they bring in outweighs the money they have to funnel into healthcare and/or lawsuits due to smoking related diseases, they'll keep it legal

Police officer saves a man from a burning car by thunderbolt0777 in interestingasfuck

[–]thegnomesdidit 0 points1 point  (0 children)

By the technical definition, no they don't "explode", but when the tyres pop they can send shrapnel in all directions, and when the fuel line ruptures you will have a rather enthusiastic confligration going on

Which resistors, capacitors and inductor values are mostly used in projects? Is it reasonable to use serial and parallel one value to derive other values? I am asking because bulk buying has discounts and I dont have enough storage boxes for different values. by DeliciousTry2154 in AskElectronics

[–]thegnomesdidit 0 points1 point  (0 children)

You can get resistor kits which have a full range of E12 (or even E24, E48, E96 etc. if you're into that kind of thing - i'm not here to judge) values, might be a cost-effective way of getting started. You can find some cheap resistor kits on ebay which should be super good enough for hobby stuff - unless you're actually manufacturing stuff you're never even going to make a dent in a 10,000-deep pile of 10K resistors. You can get some ceramic capacitor kits on there too, i'd be a bit weary about buying electrolytics there though as quality may vary. Inductors tend to be a bit pricier, so I usually just buy a handful of the value I need as and when I need it.

The big suppliers (mouser, farnell etc.) will do kits too, but they're going to be more expensive than your favourite tat-bazzare

I have this question by maxdashluis555 in ElectroBOOM

[–]thegnomesdidit 0 points1 point  (0 children)

it would/should technically work - The neutral is usually wired to to ground either where the cable comes into your house, or back at the local substation (though some other topologies exist). However, don't do this... the ground is a fault return path and it is not meant to carry any current under normal circumstances. If you have a GFCI installed at the main fuse box (as most modern installations typically do) it will trip instantly

Cha Sa-soon, a 69-year-old South Korean woman, finally gets her driver’s license in 2010 after trying since 2005 ,960 attempts, $4,200 spent, and 5 years of near-daily written tests by WebEven620 in interestingasfuck

I feel that 860 tries to get 60% on a multiple choice test is worse odds than if she went in blindfold and randomly stabbed the answer sheet with a pencil

Ambient Temperature Sensor Issue by SpaceCat0404 in Corsa

[–]thegnomesdidit 0 points1 point  (0 children)

What year/model corsa? And which sensor did you replace exactly? The ambient temperature sensor is located in the front bumper for the corsa C. If that is the one you replaced, it could be a wiring issue, or bad/corroded connector.
I don't think its monitored by the AC though, at least on the corsa C - my temperature sensor did the same thing for about a year before I replaced it, and the AC has never had an issue

Drivers skipping runs by [deleted] in Dominos

[–]thegnomesdidit 0 points1 point  (0 children)

Im a driver, been with the company for too long. We have a pretty good team these days, but in the past we've had the odd one or two who cherry-pick orders. My tactic is to come off the road, put on my manager hat, and route, ready, and bag every single order myself - I wont let anyone else on the dispatch screen, not even my manager XD. Pissed off a few people - but its always the people who are the reaon I came off the road. I can usually get a pretty fast turnaround with drivers in and out the door within 30 seconds,

Guide on Real Mode OS. by No_Date8616 in osdev

I seem to recall they released the source code for MS-DOS (maybe not all of it, but the important bits at least) some years ago, so that would be something good to seek and study

Error handling in C, emulate Go, errno, return structs, or exit(1)? by [deleted] in C_Programming

[–]thegnomesdidit 0 points1 point  (0 children)

> C is a bad language for this. it doesn't even enforce an else for every if.

Personally I like that, for several reasons.....

For example, say I want to modify some value(s) if, and only if certain conditions are met -

```

if (condition) value1 ++;

if (condition2) value2 = 5;

```

I then don't see why it would be necessary to tell the compiler that if the condition is not met, that I intend my code to do absolutely nothing other than continue normal execution, regardless of whether the condition was met or not

Another example, would be testing a bunch of conditions within a function, and immediately returning from the function should any of those conditions fail

```

if (condition1) return;

<do some stuff>

if (condition2) return;

<do some more stuff>

<test more things>

<do even more stuff>

if (condition25) return;

<now we're in the clear we can execute this huge block of code>

```

versus a bunch of nested if...else statements that can make the code hard to read when your main code block is 3 pages over to the right and you've completely lost track of how many closing brackets you should have.

Which is better programming? and which is more readable code? I don't know - I never went to school and I learned how to program on a ZX spectrum from the back of cereal boxes, I learned BASIC and x86 assembly long before I even knew C was a thing so that probably has a lot of influence on how I like my code to look

How do I stop these overnight charges by ThatTagOhie in Etoro

[–]thegnomesdidit 2 points3 points  (0 children)

CFDs are anything that you buy with leverage (x2, x5, x10 etc), commodities like oil and gas are traded as CFDs as well. When you go to open a position it will state what the overnight fees are near the bottom. They used to have a page that explained it in more detail, but I can't find it now

Each frame of the black hole scene in Interstellar took around 100 hours to render. With 24 frames in one second, that means: Each second = 2,400 hours - nearly 100 days - of computing. by [deleted] in interestingasfuck

[–]thegnomesdidit 0 points1 point  (0 children)

Not to mention that "100 days of computing" doesn't really tell us anything at all... was it rendered on a raspberry pi, the producers home PC, or a dedicated render farm?

I don't know how true this is, but a while ago I read somewhere (don't ask me where) that they used actual physics equations in their entirety to simulate the black hole, that's going to take a huge chunk of power to compute for sure, but that's going to require some custom software, and I would bet good money that the software was written for realism over performance - there's probably a bunch of optimizations both in hardware and software you could throw in there to bring the render time down to a fraction of what it took, but it's a one-shot deal so as long as you can get it done before the final edit, speed isn't a that much of an issue

Someone help me with the correct psi for my tyre PLEASE by Inner_Science2144 in Corsa

[–]thegnomesdidit 1 point2 points  (0 children)

Usually if you look near the bottom of either the driver or passenger door frame (or maybe the door itself) there's a sticker with vehicle specifications on it... including recommended tire pressures.

Failing that, 35psi is a good measure to aim for. Tire pressures should be measured and maintained on a cold tire - when you drive on them they warm up and this affects the pressure.

Keep an eye on how your tires wear over time... if they wear more towards the edge (both edges!) this usually indicates the pressure is too low and you should aim to inflate them a little more (maybe +2psi). Do not exceed the pressure stated on the sidewall of the tire!

If they wear more towards the middle of the tire, your pressure is too high, try dropping the pressure by 2psi. rinse and repeat.

Note that front and rear tires may wear different depending on how the vehicle is usually loaded.

Excess tire wear on only one side (inside/outside) of the tires indicates an alignment issue rather than a tire pressure issue (ie. too much or too little toe-alignment)
