 So we're back on the site of personal rig update 2015 now some of you pointed out That putting all this computer equipment into a closet could lead to overheating issues And while this room actually is technically an exterior room This is an insulated wall right here and through this gap is direct access to the outside and through that gap is direct access To the attic it's only passively ventilated and in practice We've gone from it being pretty close to outdoor temperature to it being about 13 degrees Celsius putting this equipment in initially To it being about 18 degrees Celsius on a warm day here in April so from past experience I'm expecting it to go as high as 35 to 40 degrees Celsius in the heat of the midsummer Obviously that's not acceptable so we're gonna have to put a contingency plan into action welcome to personal rig update 2015 part Whatever the crap this is and yes, I know it's not 2015 anymore Ventilating the room The Aria headphones from Phoenix come complete with a cardioid clip mic and acoustic chambers constructed entirely of Japanese pinewood Check out the link in the video description to learn more Now as a number of you have noted on at least several occasions I'm not particularly handy and when it comes to knocking out Walls and installing ventilation fans. I am NOT gonna be anyone's first choice as a general contractor So I have brought in my crack team Mark and Praxis who are going to be Well helping me with basically doing it for me, but before they can do that There's some stuff I need to do because I've already started using this room as storage again And I've been informed that all this yes even this that I worked so hard to put in here Has to come out. I guess we'll start by shutting everything down. I'm gonna have no internet today or tomorrow. Oh How will I live it's like a fish with no internet or water well here we go. I'm just gonna have to Pull this out of here My ceiling mounted access point There we go Such whiners. Oh, we don't have power. Oh, we're running on battery I don't actually have power in this room So this is a power bar that runs through the wall to an outlet and then everything else here is Also, just kind of running through that same hole, which is just a hole I made in the drywall is there perhaps while we're redoing these walls is there perhaps a more elegant way to achieve this Well, I could actually put outlets on this wall something I should have done six years ago, basically. Yeah. Yeah Yeah, okay Suggestions for your lighting LED pot light. Oh, neat Low voltage. Wow, those are really small So the transformer it only uses 12 watts Also, I'm not gonna have like the the incandescent cage thing hanging off Yeah, yeah, that's it. You don't like this? Oh, well, I think I actually did even put this in myself now that I think about it Yeah, it was broken in this room. I put this in Did I do okay? No So, I mean this is bizarre I I told Mark I still had some more of this like Particle board with like a prime side stuff and he and I was like, yeah, you can you can totally have that we You can put more of it in there. He's like you So we are gonna be ripping all of that out as opposed to just doing the parts we need to access and drywalling it You can see it's really sturdily constructed. I mean, it's not like he's taking it apart with his hands That's totally not a thing that's happening. Let's see if I can pull it off with my hands never. Oh, wow. Yeah, that is not very good I feel like he man just ripping walls apart fun fact never actually Seen an episode of he man. I don't even know if he man is the name of the show He man might just be like a guy on some other show. You know, it's amazing I told mark I was gonna be here to help today. He still brought a helper. I can't figure out why Inexplicable I took an electrical course in high school Thank you So I'm equipped with my manly purple mask and my light I'm gonna go find out where those damn cab 5 cables go to I think it's possible that they actually go to the To the garage like I think the house was kind of wired for ethernet But like not properly so if they go around the front and across that way Then that will be what they were for but it doesn't actually look like they do One of them goes this way. Where are you going? And why are you going there? Where are you going and why are you going there? Ew cobwebs. Ah spider! What the hell? I figured out what it is. Okay, they're using it a speaker wire This is for the um It's for the ceiling mounted speakers in the living room I don't understand why they're using cat 5 for that. Maybe there's some reason but that Explains it. Okay, so that means that this how the heck did they manage to do a drop? Unless oh This goes straight down into that wall Oh, that's cool. That means if I wanted to run anything else in that wall then I could And that is also How they're getting coax in there, I think Okay Now I get it So now that we've got everything torn out We've got a clear look at what we're working with and I can outline exactly what the plan is We're gonna pull off of this light switch box right here And we're gonna put an outlet in this room rather than having me run a power bar through the wall because i'm sure that the fire Department would freak out if they saw that next we're going to install this low voltage led lighting Doodad we have an inline 190 cfm fan which we'll use to pump air into the room We need to control that with a cooling thermostat and this is a low voltage connection and this is 120 volts. So We need to use a relay to have this tell the relay what to do in order to tell the fan what to do Okay So basically we're going to climb down Into the soffit area down there where conveniently there are already some ventilation duct things that are for Keeping this this insulation up here ventilated and we're going to put like a service panel in here and just have it create a positive air pressure situation in this room and then for ventilation out of the room what we're thinking is we're just going to leave like maybe six to eight inches of Free space here in the drywall on the ceiling so that it can just passively exhaust into the attic Just like that. So uh, we have a plan. It's exactly the plan. I would have come up with on my own, too So they're making me vacuum the rodent poop I guess I get that sort of my rodent poop not theirs So the first step which you can see praxis working on here is using a combination of the included mounting hardware and a little bit of fabrication in the soffits to create a mounting point for the intake fan that's going to cool the room the fan itself Is free flowed with air So we need to put a damper in so that when you don't want air flowing in there say in the winter when it's cold you want this to Stop the airflow Cool now the last step to make all of this even have a point at all Is to insulate the ceiling because that is where the heat is coming from from the sun Hitting the shake roof and basically conducting heat directly into this room now Fortunately, this is relatively straightforward because we've already got strapping right here So we're still going to have enough airflow through here to keep the wood from rotting But we are going to have to fill it with insulation and cover it with drywall in order to make this room Effectively part of the house rather than part of the outside So phase one of the electrical work is actually pretty much done So we've borrowed 120 volt power from the old incandescent Pulley chain light that used to be up here and we have brought it into This box right here So this is where the light switch for our new led light is actually going to go This guy is going to contain this relay right here as well as this transformer Which is going to take the 120 volt in and turn it into 24 volt power that our cooling thermostat can handle Without frying itself whenever the fan engages So basically what should happen is that we're going to have to turn the fan off What should happen is when the temperature reaches a certain threshold when it gets too warm It'll connect the circuit and in theory that'll turn on the fan Which as you guys can probably hear is working just dandy exciting So for the next stage in the project We're working on putting that electrical jack in as well as a better pass through into the room over here The other update here is that the ducting is now installed. So it's pretty straightforward stuff We've just got some little metal accordion style ducting here and then some foil tape Affixing one duct to the fan on this side So that's where the exhaust is going to come into the room and then on the other end We've got another piece of duct that's going right down to the soffit where we're going to have to cut a hole for it outside now the clever among you have probably realized at this point that that Is just going to draw air not only from the outside But also from the rest of the attic where we haven't insulated and it's going to be quite hot No, not so because we're going to jam some insulation around the edges of it so that it can only draw air from the outside okay, so with the poly over most of the insulation in the walls now and The drywall mostly well sort of maybe about half up. We're ready to do an update Because once this wall is dry walled in this led light is going to be permanently mounted. So It locks into the connector a little something like that. Then we are going to simulate the switch By doing these wires and there you go That's an led light and Brandon's going to have to adjust his exposure Oh, he's going to have to do it again. Oh, he's going to have to do it one more time. Oh, no Oh, no, Linus is living with the light So that's going to go on the wall So this is a quick status update more than anything else I realized that the fan is a little on the loud side. It's actually audible even through the wall So what we're going to add is just a simple dimmer switch and we're just going to tape it up Box it inside here and close it away because it's not the kind of thing that you would adjust very often And the other things that we can have a look at that have changed since last time Is that the fan has been completely insulated around now? So we are getting nice cool air like that is frosty air from outside And finally this puppy has been reframed for a nice big access panel If in the future I want to run Oh, I don't know more, you know foam lines or coax lines or even power From my garage or to anywhere else in the house because from here I can access the entire upstairs and Over to the garage now. I don't have to crawl through like I did the other day see much easier So we are pretty much at the end the room is dry walled and mudded The access hatch has been mostly created. It just needs a bit of a handle on the outside and Check this out. This dimmer switch has been wired in It's kind of a getaway of doing it. I know in a perfect world, you know, the rpm of the fan would be Modulated by temperature as opposed to just by manually doing this But this is functional since it's the kind of thing that i'm only going to have to set probably once a season anyway So here's how it works. We've got the fan on auto the system is set to cool and if we turn the threshold down The cooling fan kicks in But if I kind of go oh gee that's really loud all i've got to do is before I close up this little access panel Turn that dimmer switch down And we can find the perfect balance between acoustics and temperatures So finally the last step before benchmarking we've got to put a grill on the outside air intake Which is under the soffit here preferably one that is bee proof, you know, so that I don't have bees in my attic Thank you for thinking of that Um, and then we can benchmark it and find out just how well the system works. Yay wheels Okay down So all that's left now Is the final benchmark so in order to evaluate whether this was a success or failure because I don't want to just Wait around for the summer and for the computers to all overheat to find out Is to look at what the cpu temperature is under a heavy load Relative to the outside temperature when we're running intensive applications. So i'm gonna run Heaven in a window as opposed to full screen oops as well as ida 64 cpu benchmark in order to evaluate what it will be like in a worst case scenario with the door closed With our new cooling system off And then with the new cooling system engaged and so here you have it guys. This is the result Operation cool this room appears for now to have been a success Bringing in cool air from the outside is going to help a lot To keep this room cool and at the rate that that fan moves air we are circulating all of the air in this room like Every minute or so not really giving the systems any time to heat up more than they normally would Well, that was fun watching me get burned by the contractor among other things But you don't have to get burned if you switch over to ting the mobile carrier that is focused on customer service and Satisfaction first when you call them. This is crazy I actually tried it because I didn't actually quite believe it when you call them You do not speak to a robot you get put through directly to a person they answer the phone. They're like hello This is ting what? and The way that they're billing works is different from other carriers You don't have to commit to like 200 talk minutes during prime hours and blah blah blah Megabytes you pay for only what you use and the average ting bill is only $24 per month per device if you're stuck in a contract and you switch to ting they'll cover 25% of your cancellation fee up to $75 and if you head over to linus.ting.com Which is linked in the video description when you sign up at our link You'll get 25 bucks in service credit or towards a new device and the savings calculator is worth your time all you do is enter your last few bills from your existing carrier and Ting crunches some numbers and tells you whether you would save money by switching to ting So check it out at the link in the video description So thanks for coming along for this wild ride if you guys disliked the video hit the dislike button But if you want to see yet another personal rig update 2015 that I have planned hit the like button because I do have something in mind or even consider Subscribing if you really enjoyed the video and you want to see more now that you're done doing all that stuff You're probably wondering.
