WEBVTT 00:00:00.000 --> 00:00:15.800 Brown for positive with red tape before we do that can we get like a hot glue gun 00:00:15.800 --> 00:00:19.800 and just like shmoo up those leaves oh I assume there was a shroud or so I 00:00:19.800 --> 00:00:24.160 ain't no shower brother oh yeah well like well like the electrical tape or 00:00:24.160 --> 00:00:27.360 something yeah just something so that like okay your fingers there you don't 00:00:27.360 --> 00:00:31.640 like we understand why yeah well I mean it says the person to put the black on 00:00:31.640 --> 00:00:39.880 the neutral well that's a take oh just like wrap it around the whole thing 00:00:39.880 --> 00:00:44.600 it's just electrical tape I wonder if I can do something like this here let me 00:00:44.600 --> 00:00:49.000 just let me just do a thing real quick what are you doing I am going like this 00:00:49.000 --> 00:00:54.720 so that that won't come off what the problem is not even it coming off it's 00:00:54.720 --> 00:01:02.480 someone touching it well yeah how are they gonna touch it through the electrical tape okay there how are you gonna touch it now smart guy yeah 00:01:02.480 --> 00:01:08.320 exactly that's my point I mean it's way better than what you did the one safe 00:01:08.320 --> 00:01:11.560 place that you can touch you've covered with electrical tape yeah but I it's 00:01:11.560 --> 00:01:17.360 also it's like it's in the way of touching the unsafe place see look there 00:01:17.360 --> 00:01:20.840 happy now surely we know a bit more about this than what was on the LA 00:01:20.840 --> 00:01:27.760 express page a tiny bit tap tap tap tap on our forum originally showed us one of 00:01:27.760 --> 00:01:31.280 these and we were just like okay let's buy it that was pretty much the entire 00:01:31.280 --> 00:01:35.800 research that's not more Kyle tell me about the controller boards I looked at 00:01:35.800 --> 00:01:38.880 this about 20 minutes before we started shooting and we know what some of the 00:01:38.880 --> 00:01:44.880 connectors do temperature yes for what good question oh god we had to outdoor 00:01:44.880 --> 00:01:48.960 and exhaust well we had to translate that from something in Chinese looking 00:01:48.960 --> 00:01:53.320 by outdoor I didn't run this outdoors is outdoor we are assuming it means 00:01:53.320 --> 00:01:58.000 ambient I guess and the red one is exhaust of what yeah yeah we don't know 00:01:58.000 --> 00:02:03.400 okay this is a tensiometer assuming for fan control but our fan is actually 00:02:03.400 --> 00:02:06.600 wired directly into 24 volts so it's going to be running at 100% no matter 00:02:06.600 --> 00:02:11.200 what we do so we can probably ignore that one this is communication to what 00:02:11.200 --> 00:02:14.960 about what I'm assuming to a temperature controller that it communicates over 00:02:14.960 --> 00:02:23.280 UART or some sort of two-line protocol I figured something out okay you got 00:02:23.280 --> 00:02:27.080 your compressor here okay you got your condenser right here yep just like you 00:02:27.080 --> 00:02:31.280 would for an air conditioning unit but then instead of an evaporator which for 00:02:31.280 --> 00:02:34.680 your air conditioner would be another one of these that blows the cold air into 00:02:34.680 --> 00:02:40.520 your room you've got a heat exchanger so we take the refrigerant that goes 00:02:40.520 --> 00:02:43.920 through one side of the heat exchanger and then we have these two barb fittings 00:02:44.040 --> 00:02:50.840 that will take that chilled water and run it to something well you gave away 00:02:50.840 --> 00:02:54.520 the keep away the whole fun I mean I guess that was in the intro anyway so 00:02:54.520 --> 00:02:57.840 we're gonna cool a computer with it we're gonna cool anything else with it I 00:02:57.840 --> 00:03:04.640 don't know like a brassiere who knows what the fix of Brazil what I don't know 00:03:04.640 --> 00:03:08.040 are you my well do we want to try and actually turn it on first I mean I would 00:03:08.040 --> 00:03:11.800 think so yeah so we're finished with the power supply I know we got to run the 00:03:11.800 --> 00:03:16.600 DC lines yes wait how can we run this off these wimpy little whatever if it has 00:03:16.600 --> 00:03:21.360 600 watts of cooling capacity there's no way I mean here are thick these cables 00:03:21.360 --> 00:03:25.320 oh yeah exactly those are a lot thicker than these where'd you guys get these 00:03:25.320 --> 00:03:30.040 wimpy cables the wire drawer we don't have larger stuff right oh my god it's 00:03:30.040 --> 00:03:34.920 fine it's fine wait can't we just sacrifice another power cable it's fine 00:03:34.920 --> 00:03:40.600 no it's fine it's fine it'll be fine it just gets hot and then it's fine we have 00:03:40.600 --> 00:03:43.640 a fleer we can just look at them and be like oh those might catch on fire yeah 00:03:43.640 --> 00:03:51.640 if they get too hot we'll just stop but it's gonna be fine yeah it'll be fine it just gets warm that's the definition of not fine when it comes to electrical 00:03:51.640 --> 00:03:55.560 wires how how warm it gets before it catches fire you just gotta be under that 00:03:55.560 --> 00:03:59.880 also the ignition temperature is really high yeah well like you don't want to 00:03:59.880 --> 00:04:06.280 melt the sheet and forget about ignition if it melts and then shorts that's the problem oh my god the fact that I'm the responsible adult here what are you 00:04:06.280 --> 00:04:10.440 talking about this is your flippant duct tape solution yeah and you can't touch 00:04:10.440 --> 00:04:15.320 the thing did you put that on the minus side yes I know how that thing works I 00:04:15.320 --> 00:04:19.240 have no trust apparently before we hook it up we yeah yeah yeah yeah it's hooked 00:04:19.240 --> 00:04:22.920 up no we need to plug it in and make sure it's actually on these connectors 00:04:22.920 --> 00:04:28.920 there you go it's spaded she checks to make sure I plug into the right no he 00:04:28.920 --> 00:04:33.480 did I saw him what I actually hold on what I'm doing is you have to make sure 00:04:33.480 --> 00:04:38.840 it's actually out putting 24 volts because there's a trim pot here that if 00:04:38.840 --> 00:04:43.320 you do it wrong so now we get to plug in power to see if you plugged it in 00:04:43.320 --> 00:04:47.000 correctly it doesn't matter you can leave you can leave one of them and you just 00:04:47.000 --> 00:04:51.080 can't all right all right okay in all seriousness before we connect this to 00:04:51.080 --> 00:04:54.840 our compressor which for all we know could be very sensitive about its input 00:04:54.840 --> 00:04:59.720 voltage I don't know anything about DC compressors we need to verify that our 00:04:59.720 --> 00:05:03.160 power supply is actually outputting 24 volts now this is a mean well power 00:05:03.160 --> 00:05:07.240 supply and they don't just mean well they actually do well 00:05:07.240 --> 00:05:10.600 seriously it's a good power supply brand it has a potentiometer on it that can 00:05:10.600 --> 00:05:14.360 adjust the output voltage so by doing a quick checky check here 00:05:14.360 --> 00:05:19.800 24.18 volts perfect sounds good to me oh my god it's not going to matter what 00:05:19.800 --> 00:05:23.640 are you how much is 24.18 oh but why is it not 24 00:05:23.640 --> 00:05:27.000 we haven't been married long enough to squabble like this I think we squabble 00:05:27.000 --> 00:05:30.440 like this ever since our interview mate 00:05:30.440 --> 00:05:34.120 I mean in fairness to you the assignment we gave you for the interview was very 00:05:34.120 --> 00:05:37.240 stupid yeah that was Nick and Alex no that was my 00:05:37.240 --> 00:05:40.520 idea was it your idea yeah the water cooled mouse that was your idea yeah 00:05:40.520 --> 00:05:44.680 that was dumb we asked our engineers in their interviews to just 00:05:44.680 --> 00:05:48.840 brainstorm have a brainstorming session to theorize a product that 00:05:48.840 --> 00:05:52.440 you know is stupid but we used to do that is a challenge you know oh you don't 00:05:52.440 --> 00:05:56.040 do we now do trial days we just hire them for a day and give them real thank 00:05:56.040 --> 00:05:59.080 you for cutting all of this out of there whatever that's interesting it is 00:05:59.080 --> 00:06:03.160 interesting it'll be in the Floatplane exclusive yeah hey Floatplane hi so I 00:06:03.160 --> 00:06:06.280 can just go for it now we should probably fill this first and get the 00:06:06.280 --> 00:06:13.080 pump going oh yeah because you want the evaporator to actually evaporate instead of not just pumping like 00:06:13.080 --> 00:06:16.360 referring back around you've got water already wow water you were totally 00:06:16.360 --> 00:06:19.640 doing stuff while we were arguing yeah where's the return oh just 00:06:19.640 --> 00:06:23.320 straight into the ride yeah yeah where's the pump just below it the pump is in 00:06:23.320 --> 00:06:29.880 here it cools nothing perpetual motion cooling machine it cools itself whoa okay hold on hold on hold on hold on 00:06:29.880 --> 00:06:33.320 can we just show the people what power supply we're using what happened to 00:06:33.320 --> 00:06:42.360 this guy it's from the shipping damage computer oh yes i fixed it with a hammer also what i put a new fit in what brand is this 00:06:42.360 --> 00:06:46.120 i don't know i've never heard of this that's fsp fsp is great full of water 00:06:46.120 --> 00:06:49.320 and i think we're good to go one less janky thing about our setup is that 00:06:49.320 --> 00:06:53.160 instead of just jamming a paperclip into the end of our 24 pin connector 00:06:53.160 --> 00:06:56.680 we've got this little jumper block from csonic that 00:06:56.680 --> 00:07:00.280 boop we'll turn on our power supply by jump ring the green and the black wires 00:07:00.280 --> 00:07:07.400 okay hold on hold on i got this that's so much safer than putting a paperclip there what yeah it is tc well yes it's 00:07:07.400 --> 00:07:12.040 it's more professional oh wait wait wait wait oh 00:07:12.040 --> 00:07:18.680 oh oh this video uh has good luck editor vibes to it right now 00:07:18.680 --> 00:07:22.040 no it's it's gonna be absolutely fantastic time for the moment of truth 00:07:22.040 --> 00:07:28.920 our water is at 23 degrees and if this has the kind of cooling capacity that 00:07:28.920 --> 00:07:34.520 it advertises that number should go down pretty darn quickly i mean the fan's 00:07:34.520 --> 00:07:38.200 not spinning yeah this did not that's a problem 00:07:38.200 --> 00:07:42.280 no it's fine it's fine everything's fine i mean there's no d there's no ac here 00:07:42.280 --> 00:07:48.200 is it a dc compressor no it's a it's a it's a it's a three phase it's a bldc 00:07:48.520 --> 00:07:52.520 wait it takes dc in and then it has an inverter to go back to ac well why would 00:07:52.520 --> 00:07:56.600 we go ac to dc then dc to ac that doesn't seem very efficient 00:07:56.600 --> 00:08:02.840 uh no you would just go ac in and then convert to dc for your stupid fan 00:08:02.840 --> 00:08:11.080 and your ic's no no no no no no no no no no no no your car takes a dc voltage 00:08:11.080 --> 00:08:14.760 from your battery and inverts it to ac why doesn't your car just run off ac 00:08:14.760 --> 00:08:18.600 well because it runs off of gasoline no you drive an electric car you 00:08:19.880 --> 00:08:27.160 bro yeah because they don't make ac batteries no hey these motors are designed to take a dc 00:08:27.160 --> 00:08:31.560 and put you invert it and you put it into three phases and it goes the only reason why you have 00:08:31.560 --> 00:08:36.600 this is because if you don't have this you had to put this on that so you're saying that this is 00:08:36.600 --> 00:08:41.720 it's not the same it's not the same ac thing you can't just say oh that's a it uses a when you 00:08:41.720 --> 00:08:46.360 say ac do you mean air conditioning or alternating current you do this on purpose now 00:08:46.360 --> 00:08:50.680 and it doesn't you guys are bickering a lot but uh nothing's happened with this besides this chip 00:08:50.680 --> 00:08:57.720 should i just start like shorting pins no no please okay i'm gonna short these two pins 00:08:59.880 --> 00:09:05.320 you guys are too fun why is there one red led on i think the red led means it has power everything 00:09:05.320 --> 00:09:13.320 is fine no it means it has power led zero nice useful because if something if something's gonna 00:09:13.320 --> 00:09:18.760 go boom it's gonna go boom now so what i'm doing is i'm doing a very janky method i'm gonna try and 00:09:18.760 --> 00:09:27.320 like use a 9k resistor to short the temperature probes to see if it'll turn on okay that was pretty 00:09:27.320 --> 00:09:33.080 anticlimactic why does the resistor work instead of just like jumping with metal these are potentially 00:09:33.160 --> 00:09:38.840 connectors for thermistors i'm assuming it's thermistors so it's like a temperature sense of 00:09:38.840 --> 00:09:43.880 resistor oh like just like a k probe or something this is a thermocouple yeah it's got twisted twisted 00:09:43.880 --> 00:09:51.000 pairs of metal right and then they use the um the junction voltage to the ones where like the the 00:09:51.000 --> 00:09:55.240 the hotter they get the more resistance they are the more or less resistance they do yeah yeah yeah 00:09:55.240 --> 00:10:00.360 so when that happens yeah it would turn on so usually if you're going to use a thermistor 00:10:00.360 --> 00:10:06.200 it's average to 10k so 10k at room temperature got it so what i'm trying to do is make it a 00:10:06.200 --> 00:10:10.200 lower resistance to hopefully try and turn it on considering i have no friggin clue how this thing 00:10:10.200 --> 00:10:14.760 works so pretty much what i volunteered to do just start shorting things yep you're not shorting it 00:10:14.760 --> 00:10:23.160 this is not a short a short isn't it basically very short okay well that was anticlimactic 00:10:25.720 --> 00:10:29.800 okay so we really actually have no idea i assumed when they called me to set they 00:10:30.440 --> 00:10:36.840 actually know what was so i just messing with no we have no idea well hold on hold on like we 00:10:36.840 --> 00:10:40.760 gonna go to the park we wanted to do this on camera you think that we didn't google a part 00:10:40.760 --> 00:10:45.320 number line i mean anything's possible at this point do you know how much information there is 00:10:45.320 --> 00:10:48.920 what i'm trying to do is figure out how the control system works these are color coded so i'm 00:10:48.920 --> 00:10:55.000 going to start with that and if i probe the two leads there should be 3.3 voltage that 3.3 volts 00:10:55.480 --> 00:11:02.760 yeah well that's a logic voltage now if they're sending it through a voltage divider one of these 00:11:02.760 --> 00:11:09.160 are going to connect to a pin on the controller and we just gotta find the pin oh good so if it's 00:11:09.160 --> 00:11:14.120 if it is a thermistor then they'll they'll voltage divide it so they'll have the thermistor on one 00:11:14.120 --> 00:11:18.680 leg and then they'll have just a regular like a 10k over there and they'll read the voltage from 00:11:18.680 --> 00:11:23.320 between them yes right and then when the voltage reaches a certain level they turn on and when it 00:11:23.320 --> 00:11:29.320 goes to a different level they turn off right yes makes sense oh yeah that's if that's how it works 00:11:29.880 --> 00:11:36.120 so now we go to BP mode and we try and find out where everything goes probably from when it's off 00:11:36.760 --> 00:11:41.480 oh that's that's anticlimactic oh oh oh yes 00:11:44.360 --> 00:11:51.560 hey i get excited when i do this stuff okay well how the freak does that make sense that's a capacitor 00:11:51.560 --> 00:11:54.840 i kind of really want to try just putting a resistor across the potentiometer thing and 00:11:54.840 --> 00:12:00.600 seeing what happens it might need both like both like like the comparison between these two it might 00:12:00.600 --> 00:12:07.080 need temp sensors and okay all right we're adding power so you just want to basically short yeah i 00:12:07.080 --> 00:12:12.600 kind of just want to short the potentiometer thing what's surprising me is the fan's not even turning 00:12:12.600 --> 00:12:16.760 on yeah it's kind of weird well why would the fan turn on if the compressor is running because it's 00:12:16.760 --> 00:12:20.840 literally like wide straight into the power it comes off of this doesn't it yeah well yeah but 00:12:20.840 --> 00:12:26.200 there's no power running to that here's your power leads yeah yeah the the power leads are right here 00:12:26.200 --> 00:12:31.640 this is it's different yeah oh okay more than yeah we can short the potentiometer why do we need a 00:12:31.640 --> 00:12:36.360 controller at all why can't we just well because if you don't then it just ices up me well i mean 00:12:36.360 --> 00:12:40.440 not if we have a thermal load on it i don't really want to start shorting stuff that i don't 00:12:40.440 --> 00:12:46.520 have no idea what it does okay so this is calm yes that will probably go to a temperature controller 00:12:46.520 --> 00:12:51.400 uh-huh so wouldn't the temperature controller be the thing that sends back and work now signal 00:12:52.360 --> 00:12:58.760 yes so then if we short it depends on that it's probably fine it depends if it's a short now signal 00:12:58.760 --> 00:13:04.520 as in on off or it's a communication a serial communication protocol i just want to know if 00:13:04.520 --> 00:13:10.760 any of them are doing anything 24 volts dc okay so we don't want to short those two so that's a 00:13:10.760 --> 00:13:18.600 power pin yep and then everything else is either ground or data of some sort yep okay so now how 00:13:18.600 --> 00:13:23.240 do we figure out which one of them is ground go um well first for most i was going to try and check 00:13:23.240 --> 00:13:28.600 what this potential mode it does 3.3 volts which is your logic voltage again try and find what ground 00:13:29.320 --> 00:13:35.560 you can stick into short mode um and you find a known ground location i'm just a screw uh 00:13:35.560 --> 00:13:40.760 i'm not necessarily that these screws aren't necessarily connected i lie they are connected 00:13:40.760 --> 00:13:45.240 i mean on a good design they would be connected i i don't assume good designs you see they're not 00:13:45.240 --> 00:13:49.960 connected to the the the the ground of the whole system at least well i don't think you're touching 00:13:49.960 --> 00:13:55.000 it but okay that was terrible no it's fine i mean well yeah it's fine now but it could have been 00:13:55.000 --> 00:14:00.200 terrible oh it's fine now it's fine i've done worse i've done worse so they're connected to each 00:14:00.200 --> 00:14:07.960 other because they're connected through this aluminum block but they're not connected to the ground of the system okay no you never touch the ground okay um what do you mean i've got ground 00:14:07.960 --> 00:14:13.240 you got ground yeah i did touch the ground mate i'm a hundred percent sure it's the ground anyways 00:14:13.240 --> 00:14:18.200 if you touch it well if you touch the ground i need it i still need the ground okay to find the ground 00:14:18.200 --> 00:14:22.440 of the pin yeah i'm touching it we're touching ground it's like touching grass but like so in a 00:14:23.000 --> 00:14:28.280 you have a power pin and you have a ground pin okay and then you have two other pins which could 00:14:28.280 --> 00:14:34.680 be any communication protocol so we could short them no why not it's not going to do anything 00:14:34.680 --> 00:14:41.480 like it's it's probably like uart or i2c okay or something like that probably uart because it 00:14:41.480 --> 00:14:47.160 probably needs the power and the so should we get in touch with fs thermal i'll give them a call call 00:14:47.160 --> 00:14:54.120 fs thermal oh well the second result wait CPU cooler pc water wait this is actually for cooling a 00:14:54.120 --> 00:15:02.200 CPU yeah shut up i thought we were just meming on this no guess this is no way this is ground well 00:15:02.200 --> 00:15:06.520 they just have the exact same unit a hundred times for different reasons i can i can i can almost 00:15:06.520 --> 00:15:12.840 guarantee that if we do something like this and we find the correct combination of resistors to 00:15:12.840 --> 00:15:16.600 turn it on what do you mean they've actually been getting in touch with us well why are we guessing 00:15:16.600 --> 00:15:20.120 damn it you guys well because we thought that it would just turn on when we gave it power 00:15:21.480 --> 00:15:34.600 hi um any english wow amazing um we bought uh one of your chiller module units on aliexpress and 00:15:34.600 --> 00:15:41.640 we couldn't find any schematics for the controller board is it possible for us to get um a diagram 00:15:41.640 --> 00:15:50.200 of what all of the pinouts are on the on the controller board yeah i have we chat 00:15:51.080 --> 00:16:00.360 let me get a bunch of resistors oh my goodness hey some a plus a plus telephone support right 00:16:00.360 --> 00:16:05.320 there wait are you still trying to get it to turn on we have support right now okay well like i said 00:16:05.320 --> 00:16:09.160 race is seeking it to turn on the quickest you try your method i'll try my method whoever gets it 00:16:09.160 --> 00:16:13.800 working first what if you break it then it wasn't working the first place 00:16:17.000 --> 00:16:18.120 what's the worst it can happen 00:16:22.600 --> 00:16:31.000 i didn't think it did anything it just it's like who has faith in you he's just gonna send us a thing 00:16:31.000 --> 00:16:38.600 what thing is he are you talking to me i will okay yeah until that happens i'm gonna try my method 00:16:39.160 --> 00:16:43.400 do you know how you need to constantly keep busy you think i'm in any different 00:16:45.640 --> 00:16:52.920 how the f*** do you work oh no there's probably resistors that do oh mother oh i hate this thing 00:16:52.920 --> 00:16:58.760 already nothing's my fault what are you so excited about i found the pin that something connects to 00:16:58.760 --> 00:17:07.480 what i'm trying to okay this is my degree i spend multiple hours looking at boards trying to deconstruct 00:17:07.480 --> 00:17:13.320 what they are by probing stuff right it's like what i'm doing is i'm visually building a schematic 00:17:13.320 --> 00:17:19.880 of where these pins go so that i might be able to deduce what i need to do to get them to work 00:17:19.880 --> 00:17:24.520 what if we visually create a schematic by just downloading the schematic from the manufacturer 00:17:24.520 --> 00:17:28.600 because they don't have one you think i would have you think i would be doing this if the 00:17:28.600 --> 00:17:32.920 schematic was available it does kind of seem like you're doing it for fun at this point yes thank you 00:17:32.920 --> 00:17:37.160 thank you thomas you see how organized our resistors are in crater warehouse look at this 00:17:37.160 --> 00:17:42.520 see look at this you see when i'm looking for 10k you see it says 10k right over there so now i know 00:17:42.520 --> 00:17:50.280 there's 10k there i'll accept it's not there we're like we're gonna cut that part out the back bones 00:17:50.280 --> 00:17:55.960 connect to the front bone okay you see that bone is connected to this bone oh i could have just 00:17:55.960 --> 00:18:02.760 followed the traces so that is connected to a transistor why are you connected to a transistor 00:18:03.800 --> 00:18:15.560 oh it's a logic level is there some chance that we will need an additional board we do not have 00:18:15.560 --> 00:18:20.840 to power this thing there is a non-zero chance that's possible i see i think it's pretty low though 00:18:21.480 --> 00:18:26.440 okay do i call the guy again i don't want to be like that but oh okay 00:18:29.400 --> 00:18:32.600 okay plus side even if he doesn't answer we can all listen to this song 00:18:39.880 --> 00:18:44.520 oh come on that's the sound of a man who's losing a race slightly by less than before 00:18:45.320 --> 00:18:53.800 all right well i just got noped so much for the amazing phone support 00:18:54.920 --> 00:19:00.200 sounds like a man who's losing a race like why do we always start like these things and then we 00:19:00.200 --> 00:19:05.080 have a plan we start so well and then it just avoids into from chaos this is even when this video 00:19:05.080 --> 00:19:09.000 was supposed to be chaotic though yeah i don't even think we started with a plan so i don't know 00:19:09.000 --> 00:19:13.080 what you're talking about the plan was power it on and be like wow it's cold and then that didn't 00:19:13.080 --> 00:19:19.480 happen this is one shot do not miss spaghetti this is the potentiometer that i found 00:19:21.960 --> 00:19:24.280 connecting it to the potentiometer port and just spinning it 00:19:26.600 --> 00:19:31.960 it didn't do anything man why did i let him off the phone once you're on the phone with support 00:19:31.960 --> 00:19:38.760 don't let support off the phone until you've been support oh that's not well i just all i want is 00:19:38.760 --> 00:19:45.400 a schematic let's not well he has it new plan i'm gonna get andy to contact support from a 00:19:45.400 --> 00:19:54.120 different phone number i think i might know how to turn this on because if i'm wrong what i did was 00:19:54.120 --> 00:20:01.400 excuse my chicken scratch but using using probes and my knowledge i went from this lead over here 00:20:01.400 --> 00:20:06.920 which i'm thinking is a control lead that goes to the controller and worked my way back to the 00:20:06.920 --> 00:20:14.600 microcontroller okay so this is the lead and it goes into a resistor that is over here next to 00:20:14.600 --> 00:20:20.360 this big chunky capacitor then it goes into this three pin device which i'm assuming is either a 00:20:20.360 --> 00:20:30.280 MOSFET or a transistor and they both have very similar layouts so i was able to find a very equivalent 00:20:30.920 --> 00:20:37.080 like part of the internet downloaded the datasheet figured out where the base collector 00:20:37.080 --> 00:20:42.680 meter are and was able to draw the circuit that's the transistor which is that little tiny black 00:20:42.680 --> 00:20:49.080 thing over there and then that resistor is this resistor over there and then there goes a trace 00:20:49.080 --> 00:20:58.280 down to the lead and then there is another resistor somewhere over here that then goes to the microcontroller 00:20:58.280 --> 00:21:07.960 so what i'm thinking is if we put voltage like 24 volts on the lead okay it will turn this transistor 00:21:07.960 --> 00:21:15.880 on which will ground wait hold on tell you what i'm gonna run but i'm gonna keep my mic pack 00:21:15.880 --> 00:21:23.320 and what's gonna happen is when kevin calls me i will film myself we'll have good audio and then i 00:21:23.400 --> 00:21:28.360 will get you guys the diagram that you need okay and then if i turn it on before lunch 00:21:29.080 --> 00:21:33.000 because we're even right now all right fine yeah we each owe each other lunch so nobody 00:21:33.000 --> 00:21:38.040 has no lunch in fact i don't think we've ever gone for lunch to go so i won two because i predicted 00:21:38.040 --> 00:21:46.120 two sales oh then you won a power supply guessing one from the six graphics cards and then you won 00:21:46.120 --> 00:21:52.920 stubby sales which i don't really know if i have to win yeah win it's an ally was right about 00:21:52.920 --> 00:22:01.080 and if you break it you extra lose uh whoops if you break no it's fine what do you mean it's fine 00:22:01.080 --> 00:22:06.520 it's fine so what what i think i've done is reverse engineered the control circuit or what i think is 00:22:06.520 --> 00:22:11.560 the control circuit i'm going to try and turn it on with a lower voltage just in case i do send it 00:22:11.560 --> 00:22:18.200 to narnia i if i put 24 volts it's much more likely to go to narnia than 3.3 so i'm trying to find 00:22:18.200 --> 00:22:26.840 a 3 volt a 3.3 volt rail and then we're gonna try from there okay that is 3.3 okay this is spooky 00:22:27.560 --> 00:22:29.640 ah i i mostly know what i'm doing 00:22:32.440 --> 00:22:34.280 that didn't work darn
