How Norwgian cops handles a drunk, angry person!

01:18

@DannyBeckett That does seem unreal. Here we just taser them.

Danny Beckett

yeah here we'd just have 20 coppers diving on him

voretaq7

(we used to just shoot them, but we've discovered they have a better chance of not dying if we taser them. Not sure if it's easier to defend the brutality suit for the taser or the wrongful death for the shooting though)

@DannyBeckett no, I'm serious - the NCPD manual allows you to taser a suspect if they try to kick you and you can't otherwise control them

Danny Beckett

yeah that's why I thought it'd be interesting to you guys, since your cops are brutal :p

voretaq7

(you're supposed to try to take them down and put the ziptie on their ankles first, but it's much easier after they've had a few kV run through them)

Danny Beckett

lol I watch Cops...everyone gets tasered

voretaq7

01:21

@DannyBeckett This bothers me because the taser is an inherently unsafe device

@DannyBeckett you occasionally have to haul your fat ass up steep inclines and through tight spaces

I'm actually kinda sad I need to start lifting weights or something - I don't think I could do any kind of near-vertical climbs anymore. I'm totally out of shape :-/

Danny Beckett

in all seriousness, I'm just figuring out the components and circuitry. I'll eventually get a PCB made, to proper size, in the proper panel

shortstheory

makes sense

Danny Beckett

@shortstheory on the video? FSX

shortstheory

for which sim btw?

oh

Danny Beckett

:)

shortstheory

01:34

I've read that the circuitry for toggle switches isn't exactly straightforward

lolwut is 5A over USB actually a thing?

I could power a 25W light bulb with a USB port!
:D

Danny Beckett

@shortstheory you're exactly right

because using a keyboard card, a toggle switch would hold down the key on the keyboard

shortstheory

yeah, keyboard card

that's the thing I read about

Danny Beckett

you need to use a relay and capacitor

the green PCB is the keyboard card

shortstheory

i forgot how it works, but I think I read pretty much the same thing :)

01:37

are you going to make the displays for the A/P too?

Danny Beckett

I just took 16 of the 24(?) wires of an IDE cable and soldered it to the board

shortstheory

eg for IAS/MACH/Heading

smart

Danny Beckett

currently, the relays just plug in with wires into the IDE connector, but I want to get the matching IDE plug off an old motherboard and make it properly

yeah I haven't looked into how to do that yet, but I do want to

@shortstheory 5A isn't possibly on USB 2 at least. That's why I used the power brick. USB 3.1 however....

4 hours ago, by Danny Beckett

> Using three power profiles of those defined in the USB Power Delivery Specification, it lets devices with larger energy demands request higher currents and supply voltages from compliant hosts—up to 2 A at 5 V (for a power consumption of up to 10 W), and optionally up to 5 A at either 12 V (60 W) or 20 V (100 W).

casey

@shortstheory the circuitry wouldnt need to be too complicated. A simple T flip flop would do.

Danny Beckett

all of my (6) questions on Electronics.SE cover how I've got to this stage: electronics.stackexchange.com/users/36617/…

shortstheory

01:42

I just thought of something: wouldn't powering 8 x 25W USB devices on your desktop screw up the PSU pretty soon?

:)

Danny Beckett

it boils down to..

shortstheory

like my laptop's power brick is only 65 W, so I used 3 x 25W devices + (IDK, maybe 30W for the laptop itself?), I'm pretty sure I'll be exceeding the design limits of the brick.

Danny Beckett

from my understanding, the device can request a certain amount of power

but the OS decides if it gets it

shortstheory

ohh

Danny Beckett

there's a little section in Computer Management about it, in fact

if you go on the properties of a connected USB device, somewhere it tells you the requested power draw and how much was allowed

casey

01:45

@DannyBeckett do you run into problems with key ghosting with that setup?

Danny Beckett

@casey as in sometimes the key is hit more than once? no

casey

I'd favor a setup of T flip flops or perhaps RS latches to handle the toggle logic and switch lighting, but a keyboard controller does simplify the computer interface

Danny Beckett

I used a different uF capacitor though... a different value would have that effect

shortstheory

does anyone have experience with Arduinos here?

casey

@DannyBeckett no, not that, with many USB keyboards for example, they can only register 6 keys pressed at once

shortstheory

01:46

I need a little help :d

casey

it seems like "holding down" keys to handle a switch would hit that limit

shortstheory

should I go with 2 of these breadboards: protocentral.com/breadboards/…

Danny Beckett

@casey ah, that! everything I've read says "just override existing keys, there are tons, and it's easier than trying to get it to press multiple keys"

shortstheory

or should I just get 1 full size breadboard?

Danny Beckett

I did read one thing, which just said you need to put a 25ms gap between key presses

@shortstheory nope, sorry

shortstheory

01:48

okay, help on just the breadboard would be good enough? :)

Danny Beckett

@casey holding down keys? no, it converts it to a momentary keypress

Bret Copeland

Danny Beckett

@shortstheory I just soldered wires to eachother

we don't need no stinkin' prototypin'!

shortstheory

but I do!

I've an idea for replacing the pitot static system on airplanes!

okay, not replacing

more like redundancy for the P/S system in lieu of AF 447, and possibly MH 370

casey

@DannyBeckett ah, i misunderstood :)

shortstheory

01:51

i think I'll build my prototype with arduinos and stuff

Danny Beckett

@casey ah ok! :) yeah, a standard toggle switch without the relay/capacitor would do that

shortstheory

(this probably sounds sort of uneducated, but I kind of know what I'm doing)

Danny Beckett

@shortstheory what's the idea?

shortstheory

sound :)

Danny Beckett

^o)

shortstheory

01:53

IMO if you know the distance between the transmitter and the receiver of sound, you can calculate the Mach number by measuring the delay it takes for sound to reach the receiever

Danny Beckett

.....radar?

shortstheory

nope

radar wouldn't give you your airspeed would it?

Danny Beckett

True (just groundspeed, right?). I don't see where you're going with this, but good luck!

shortstheory

google science fair 2014

i would fit in with the 15-16 age bracket

Bret Copeland

@shortstheory you can already get altitude and ground speed from GPS. What you don't get from it, which you can really only get from the pitot-static system, is airspeed.

shortstheory

01:56

Which is why the P/S system desperately needs redundancy

Danny Beckett

I still don't understand how you're gonna get airspeed using sound...

Bret Copeland

yeah, nor do I

Danny Beckett

:p

shortstheory

not airspeed per se, but you can definitely find your mach number

Bret Copeland

which, again, you can already get from GPS.

shortstheory

01:58

really?

Bret Copeland

in terms of ground speed.

not airspeed.

shortstheory

i thought GPS only gives G/S?

how do you get the mach number from the GPS?

Bret Copeland

how will you get it from your system?

Danny Beckett

> Airspeed Reference units can be manually toggled between IAS and Mach units using the SPD Key

shortstheory

Right

casey

02:00

@shortstheory it is redundant. my jet had 3 of them

Danny Beckett

Garmin G1000:Socata User Manual (Page 398 of 542) - manualslib.com/manual/358397/Garmin-G1000-Socata.html?page=398

shortstheory

So, my idea is to place a transmitter (a speaker) at the front of the airframe, and the receiver somewhere near the back

the distance between the two is known

so, now, if you can measure the delay it takes for a sound wave to reach from one end of the plane to the other, you can calculate your mach number by knowing the speed of sound

Danny Beckett

that isn't gonna work, I don't think

casey

@shortstheory your problem is your reference frame

Danny Beckett

the plane's gonna have travelled that distance in nanoseconds

shortstheory

02:02

close actually. I think it's in the order of ms :)

@casey could you specify?

Bret Copeland

It's an interesting idea.

Q: Just making sure I won't fry my motherboard?

I'm building this circuit, which converts a toggle switch to a momentary one, which sends a key to a USB keyboard PCB by connecting 2 contacts together: I just wanted to check, how do I know the keyboard PCB won't get fried when I flip the switch to 12v DC? Or worse my motherboard?

Anonymous

Danny Beckett

hahahaha

casey

@shortstheory if your system is inside the airplane, recall that the "atmosphere" in the cabin is in motion with the airplane, and from the point of view of an occupant it appears at rest (in unaccelerated flight). Sending a pressure wave through the cabin is going to take the same time to reach the other end of the cabin regardless of the airspeed. To get the airspeed of an object you need to bounce your pressure wave from an object stationary with respect to the wind onto the airplane.

Bret Copeland

@casey I'm pretty sure he meant outside the cabin.

casey

Its hard to get an object broadcasting stationary w.r.t the wind, so instead we make them stationary w.r.t the ground and use EM instead of pressure and then call it radar.

Bret Copeland

02:18

@shortstheory I feel like, as a thought experiment, your idea works. It at least makes sense to me why it would work (which means nothing... I'm full of wrong information). I've very skeptical that it would work from a practical perspective though. Seems like it might require a lot of calibration, could probably be expensive, could be very susceptible to changes in the airflow around the aircraft, or natural disturbances, and is almost certainly more difficult and expensive than pitot static.

casey

@BretCopeland I considered that but I'm having a hard time picturing something capable of producing more sound than the wind or something to discern the two at the far end.

its loud out there!

Bret Copeland

@casey you don't have to produce more sound, you just have to produce it at a discernible frequency and amplitude.

However, that is partially what I meant by it seems like it would work in theory, but might be less useful in practice.

casey

and yea, at least in the EMB we get some crazy noise at high speed right above the cockpit from a particular airflow pattern going transsonic (or so they tell us), and this would probably mess with efforts to do this

@BretCopeland Agreed, that was the "or discern the two" part of my comment

@shortstheory I'll also point out that altitude derived from static pressure is explicitly required for things like flight into RVSM airspace

so you can't get rid of the static system, and I'm not sure this would be a feasible (practical) improvement on it

shortstheory

yes I meant outside the cabin :)

@BretCopeland you've pretty much hit the nail on its head

I was thinking of ultrasonic frequencies so you don't accidentally wake up pax sitting in 1st class with annoying sine waves :)

@casey thanks for your inputs

I appreciate having a real pilot going over it too!

Bret Copeland

@shortstheory how do you know we're real pilots? I assume everyone here is a fraud. Especially me.

Danny Beckett

02:31

casey

@BretCopeland I have video evidence

Danny Beckett

got a link?

casey

though not public, since people might complain me recording an approach and landing into Freeport

@DannyBeckett I could upload it...

Bret Copeland

@casey why would people complain?

Danny Beckett

@casey I'd be interested to see it!

casey

02:33

but then again, its only my voice on that video, and not my likeness, so it probably wont prove anything

ok, i'll stick it on youtube, give me a couple minutes

shortstheory

@BretCopeland casey said he's a pilot and he's knowledgeable about aviation enough to fool me if he isn't

Danny Beckett

this ^

casey

I could take a picture of my CBA too. Sure, i have plenty of manuals for airplanes, but that doesn't prove anything. However I don't think anyone collects union CBA documents for fun...

shortstheory

I want to become an aerospace engineer, but I'm worried that the job market will totally flush out after fossil fuels become completely exhausted :(

Danny Beckett

I don't think that's a valid concern for a while...

at least in our working lifetimes

shortstheory

02:38

I'm 16, I think I have some time left :d

Danny Beckett

you think oil will have run out within 50 years?

shortstheory

i remember reading 40 years somewhere

anyway, when we're down to 10 years of oil left, it's gonna be mighty expensive by that time

Danny Beckett

there'll be other fuel

e.g. nuclear, or something else

like whatever the car manufacturers are doing with hydrogen now

shortstheory

we'd have to redesin how a jet engine works completely

@DannyBeckett: I like H2, but the reality is, it doesn't carry much energy per unit volume

not so much a problem for cars where limited range isn't completely catastrophic

but airplanes?

Danny Beckett

point is, that's not a valid concern for a job ;)

shortstheory

02:41

ofc vol depends on pressure

but you don't want to ignite the h2 in your tanks under extreme pressures

sounds good :)

@casey that place looks beautiful... nice approach and landing! don't you get the "50.. 40.." callouts in that aircraft?

casey

the other guy was flying that one, I was sightseeing

@DannyBeckett no 50 / 40/ 30 / 20/ etc in our planes

but our mains weren't so far back that you needed the help to judge touchdown

Danny Beckett

sure, I was just wondering :)

I want to learn to fly in 2015

this website just makes me want to fly more and more

Bret Copeland

@casey do you ever get to fly anymore?

Lnafziger

It's not just about the mains... I have the countdowns in my Falcon (and in fact have a 5' callout that I've never gotten in any other airplane.. I actually like it, lol.)

I'm going to see if they can give me a 3', 2', and 1' callout too. Maybe even 6"?

Okay, just kidding on that last one. ;-)

anyway, off to bed. cya all later!

Danny Beckett

@Lnafziger only a "100" callout in this Falcon 900 :(

@BretCopeland not often... When I finish up my PhD and start working again I'd like to build an RV-10 or something similar and then fly that all the time.

casey

03:41

@DannyBeckett find an episode of the aircraft repo reality show. That guy basically finds a plane, makes sure it is legal and has its logbooks and steals it back for the bank using nothing but a type rated pilot.

Danny Beckett

@casey yeah that show's all b.s. though isn't it?

casey

the show might be (the dramatic thefts) but reality isn't so far away either. repo guys are sneaky

Danny Beckett

I think it's remarkable that big aircraft don't have keys though

casey

its just like having a car repossessed. If they can find it they'll either have copies of the key or a tow truck, and they'll just take it, because legally they can

@DannyBeckett what would a key get you that you don't already have?

even the small planes with keys are nothing close to the sophistication of a car key

for the small pistons is more like your suitcase luggage key to be honest

it is the most minor of theft deterrents

For example in an EMB-145 to start the airplane cold to engines running you need to turn on the batteries, turn on fuel pumps, start the APU, configure the bleeds, start the engines, turn on the hydraulics, cycle the FADEC and find the parking brake and tiller.

thats at the bare minimum with none of the normal first flight checks and tests

Danny Beckett

@casey sure but as @Bret mentioned, if you're a pilot, you're gonna know how to do that stuff... a key would stop you getting in

casey

03:49

If you are familiar with jets you could probably figure it out, true

Danny Beckett

astonishing, imo

Bret Copeland

planes are worth a shit ton of money. If it were actually a significant problem, airlines and manufacturers would have added additional security measures by now. The fact that they haven't points to it not being a problem.

Danny Beckett

except for the video you posted from ABC... I suspect it won't be the last time either

casey

even the seminoles I used to instruct in needed no keys

you just needed to know where the battery and mag and starter switches were and what the mixture and prop levers did

Danny Beckett

ok guys, good talking... bed time for me, seeya!

casey

03:54

night

Bret Copeland

later

casey

@BretCopeland if it were a problem it would be the aircraft lessors that would mandate keys, but you are correct that its not a problem.

there was more security to get into our sims than the planes, although the sim did cost more than the plane....

Bret Copeland

@casey well, I assume it would actually be insurance companies which would mandate it if it were a problem, but it would be the operators and manufacturers who would be responsible for doing it.

operators/owners

shortstheory

04:14

@casey thanks for sharing, that was pretty cool :)

I found some nice aviation questions here: airliners.net/aviation-forums/tech_ops

Is it okay if I repost some of them on aviation SE to get better answers?

Bret Copeland

04:42

@shortstheory it's okay to post questions here if you think they will get a better answer. Just make sure to not copy and paste from elsewhere. Also, try to limit what you ask to just the things you're interested in. In other words, don't post a flood of questions you found on the internet just to bump the site's question count.

shortstheory

05:32

Thanks, got it

How do airplanes get repossessed anyway? There's a show on discovery iirc for that, but isn't repossessing tantamount to stealing?

Shouldn't the guys doing that be in jail?

I imagine it would suck for the owner of the plane to discover his multimillion dollar craft goes missing overnight :(

roe

06:23

@shortstheory I watched one episode of that, and to me, it seemed very much fake. There's a guy on youtube video taping and uploading his repo work (of cars, not airplanes) hoping to get donations for the cancer treatment of his wife iirc. Pretty much no sneaking around and stealing stuff, more walking up to the door and going "good afternoon, here's my paperwork, I'm taking the car with me, y'all mmkay with that?"

Although, I can imagine he's one of the nicer ones.

ratchet freak

07:44

@shortstheory if you have a plane that isn't paid in full then it technically is owned by the company lending you credit, if you fail to pay then they are allowed to take measures to collect back the plane

@roe I've seen another repo show ("repo men" I believe it was called) and most of the time they walked up to the car checked the vin and then started towing. If the owner showed up then the yelling started.

roe

@ratchetfreak exactly, so there's no need to break or sneak into airports, they have every right to be there and pick up the plane.

@ratchetfreak I think every repo guy would somehow notify the people he towed the vehicle, or they'd have to deal with a shitload of stolen vehicle reports.

ratchet freak

@roe yeah but the owner may make that difficult by refusing to return the plane, etc.

roe

@ratchetfreak sure, but not airport security

ratchet freak

@roe yeah the bank is required to call the owner about late payments etc. but if you are late paying then you are not likely to just return the car

@roe private airfields with private security

roe

@ratchetfreak still

ratchet freak

07:51

@roe from the episodes that I saw it was mostly from there that the planes were repoed

roe

Q: Range of smaller jets is less then bigger ones because they cannot/do not carry enough fuel or there are other limitations also?

ratchet freak

almost the entire wing is a fuel tank on most planes

plus a tank in the body

also larger jets are faster/go higher where they use less fuel

Farhan

I know wings are tanks.

I noticed that some smaller jets have ceilings at 51000' whereas 787 or A380 have as less than 45000'.

ratchet freak

depends on the fuel burn, some can be really efficient if there is no dead weight (pax and luggage)

@casey To be fair, a space shuttle didn't get there under its own power

also, the SR71 is transporting.. 2? people ;)

casey

SR-71 needs a refuel after takeoff and about every 90 minutes when supersonic, so its not getting far without external help either
