01:03:17 <EEVBlog> New EEVBlog Tweet: In 45min @gotsatoshi is supposed to reveal the true identity of Satoshi Nakamoto Most likely to be a publicity stunt for someone or some thing, a joke, just plain wrong, or some feel good wank like "We are all Satoshi" Least likely, the actual true identity(s). I'm going to bed.
03:42:31 <steve30> I got a bit of sunburn earlier
03:44:26 <T3sl4> :(
03:44:43 * T3sl4 gives steve30 a thing of salve
03:46:04 <steve30> :)
03:46:35 <T3sl4> you can get Halcyon_ to put it on for you :P
03:46:48 <steve30> I'm sure he will
05:30:09 <Halcyon_> Yup :P
05:32:08 Nick: Halcyon_ is now known as Halcyon

11:46:13 <EEVBlog> New EEVBlog Tweet: I don't understand this car shape. It looks silly, and has an impractically small boot. Why not square up the back a bit and make it more practical? Same wheelbase footprint. I guess it's "cute" to some demographic. https://t.co/Lgu6Otcmba
12:09:25 <EEVBlog> New EEVBlog Tweet: Bullshit. Won't happen. Tesla plans to have 1 million self-driving robo-taxis on the road by 2020 https://t.co/9pQFcPYkfS via @SmallCapsASX

16:22:26 <EEVBlog> New EEVBlog Tweet: Robo-Cabs PREDICTION #1: Robocabs that can match a human driver in practicality are *many* years away. Perhaps even a decade or more. Anyone talking next year is kidding themselves. And they could still suck in many situations.
16:28:29 <EEVBlog> New EEVBlog Tweet: Robo-Cabs PREDICTION #2: People taking Robo-cabs won't like or trust traditional looking cars with an empty front seat and steering wheel whizzing around. Expect something different to win out.
16:29:30 <EEVBlog> New EEVBlog Tweet: Robo-Cabs PREDICTION #3: Johnny Cab won't happen. People will detest humanoid robots trying to interact with them.
16:37:32 <EEVBlog> New EEVBlog Tweet: Robo-Cabs: PREDICTION #4: The "one bad experience" problem may seriously hamper initial Robo-Cab adoption. And with social media how it is, all you'll hear about are the bad experiences. The media & your Facebook friends will lap it up. Although, Facebook could be dead by then...
17:52:24 <steve30> morning
19:11:21 <Halcyon> Hey Steve :)
19:11:30 <Halcyon> Hey Ampera
20:10:52 <K> hello
20:13:45 <Stiff> hello
20:13:52 <Halcyon> hello
20:13:52 <EEVBlog> Hello there, Halcyon!
20:15:01 <Halcyon> \o/
20:15:13 <steve30> hello
20:15:22 <Halcyon> YAY! Steve!
20:15:33 * steve30 passes Halcyon a sunburnt paw
20:16:11 <Halcyon> Awww, you been out in the sun?
20:16:24 <Halcyon> Didn't put sun cream on?
20:16:27 <steve30> I got a little bit burnt when I went out yesterday
20:16:41 <Halcyon> Silly boy
20:16:48 <K> toasty!
20:16:52 <steve30> no, i don't use suncream much. I don't tend to get enough sun to warrant it normally.
20:17:14 <K> sunscream
20:17:47 <Halcyon> You can still get burnt on cloudy days mister
20:17:56 * steve30 curls up on Halcyon's printer
20:18:02 <Halcyon> :)
20:18:12 <Halcyon> Do you use Whatsapp Steve?
20:18:18 <steve30> nope
20:18:28 <Halcyon> Well then, I won't send you a video :P
20:23:49 * steve30 makes food
20:59:46 <steve30> mmm, food was nice
20:59:48 <steve30> coffee time now :)
21:05:24 <Halcyon> What did you have for food steve30
21:05:27 <Halcyon> ?
21:09:29 <steve30> chicken breast, roast potatoes, yorkshire pudding, gravy, brocoli, carrots
21:23:39 <Halcyon> Nom
21:24:01 <Halcyon> Oh hey steve30, how much is postage (generally) from UK to AU ?
21:24:08 <Halcyon> Expensive?
21:44:57 <steve30> When I send christmas/birthdays cards to australia its usually about £1.80
21:45:11 <steve30> lightweight letters are cheaper
21:45:23 <Halcyon> I'm trying to order printer ribbons for my dot matrix (I only have the one cartridge) and they have been discontinued for a long time
21:45:29 <Halcyon> But Amazon UK have some in stock
21:45:35 <Halcyon> But they don't ship directly here
21:46:07 <Halcyon> I was wondering if we could come to some kind of arrangement? Obviously I'd pre-pay you
21:47:10 <steve30> Up to 100g is £5.25, up to 250g is £6.05, up to 500g is £9.20
21:47:19 <Halcyon> Not so bad.
21:47:27 <Halcyon> Can we chat in private?
21:48:01 <steve30> I can probably get some for you, but I don't normally use Amazon myself, so might be worthwhile looking at other suppliers
21:48:05 <steve30> sure

23:31:59 <Nothing\> mm bacon mcgriddles are awesome
23:32:10 <Nothing\> only fast food breakfast food i can stomach, the rest of it's all swill
23:34:13 <Nothing\> except now the miasma of maple has permeated the flesh on my hands :/
23:35:07 <K> "Miasma of Maple" sounds like Canadian goth-metal band
23:35:16 <Nothing\> anyway if anyone's looking for an electronics channel, this one's proven to be on par with dave and clive
23:35:18 <Nothing\> https://www.youtube.com/user/w2aew
23:35:29 <Nothing\> lol K i was just thinking it sounded odd
23:36:07 <K> w2aew is very good
23:36:38 <K> most of rf stuff is over my head, but still
23:36:49 <Nothing\> yeah i really like his circuit fun videos, i've been learning a ton of application stuff from them, and usually i learn several different concepts at the same time
23:37:14 <Nothing\> oh yeah i don't usually watch his stuff on RF, but his circuit fun series is great, i've been learning how ramp generators work
23:38:33 <Nothing\> i was trying to figure out how to make a ramp generator by charging an inductor with a constant current source and have a comparator check the voltage of the inductor vs a reference so when it gets up to the reference voltage, the comparator activates a switch that shorts the inductor, ideally bringing everything back to the starting point
23:39:19 <Nothing\> but i didn't have any hysteresis element in there so once it hit the reference voltage the switch would just jitter back and forth uselessly as it hit the reference voltage then immediately dropped below it, basically turned it into an oscillator
23:39:40 <Nothing\> which makes me realize why the 555 was made the way it was, with the 2 comparators
23:41:03 <Nothing\> i really wanna make a sine wave generator, like a phase shift oscillator or something but you need a fairly accurate dual rail supply, i tested out some simulations where my negative rail was a half a volt to a volt higher than it should have been and it really affected the stability
23:50:31 <Nothing\> i was trying to make this RF detector last night, but not having a lot of success
23:50:50 <K> no rf to detect?
23:51:17 <Nothing\> the basis of it was you take a loop of wire the length of the wavelength you're looking for and connect a diode and LED to it and the LED should light up if it detects the specifci wavelength
23:51:43 <K> hm, without any amplification?
23:51:49 <Nothing\> nah i was doing it right around a cell phone, trying different things to send data or wifi, then i altered the loop accordingly and tried it right in front of my microwave to see if it could detect any leakage
23:52:05 <Nothing\> yeah it should work without amplification but today i wanna try passing it through a darlington pair
23:52:21 <K> hmm
23:52:35 <Nothing\> but i'm thinking if i'm using a DP, do i even need the diode, cuz the PN junction should rectify the signal anyways, no use in having another PN junction drop in there
23:53:00 <Nothing\> darlington pairs are awesome, you just look at it funny and it turns on
23:53:08 <K> hehe
23:53:17 <Nothing\> i've seen ghost detectors based on them cuz they'll just turn on randomly from coupling to the mains in the wall
23:53:57 <Nothing\> actually that was one of the first circuits i played with
23:54:10 Quit: ServalSpots ([email protected]) Ping timeout: 121 seconds
23:56:37 <Nothing\> the tutorial for that RF detector even said the loop doesn't have to bee the exact same size, so i made mine close enough but i didn't get so much as a flicker from it, so i dunno what's up with that
23:57:09 <Nothing\> he was using older 900mhz phones in his example but i figured as long as i compensated for the frequency it shouldn't make a difference
23:59:12 <Nothing\> that reminds me, i've got this ancient 900mhz bell south cordless phone i wanna tear down
