1
00:00:00,199 --> 00:00:08,639
so we're back on the site of personal rig update 2015 now some of you pointed

2
00:00:05,839 --> 00:00:14,480
out that putting all this computer equipment into a closet could lead to

3
00:00:11,400 --> 00:00:17,400
overheating issues and while this room

4
00:00:14,480 --> 00:00:22,359
actually is technically an exterior room this is an insulated wall right here and

5
00:00:20,080 --> 00:00:27,119
through this Gap is direct access to the outside and through that Gap is direct

6
00:00:24,400 --> 00:00:31,720
access to the attic it's only passively ventilated and in practice we've gone

7
00:00:29,759 --> 00:00:36,879
from being pretty close to outdoor temperature to it being about 13° C

8
00:00:34,840 --> 00:00:42,760
putting this equipment in initially to it being about 18° C on a warm day here

9
00:00:39,879 --> 00:00:50,239
in April so from past experience I'm expecting it to go as high as 35 to 40°

10
00:00:45,680 --> 00:00:51,760
C In the Heat of the midsummer obviously

11
00:00:50,239 --> 00:00:56,359
that's not acceptable so we're going to have to put a contingency plan into

12
00:00:54,199 --> 00:01:01,120
action welcome to personal rig update 2015 part whatever the crap this is and

13
00:00:59,079 --> 00:01:05,359
yes I know it's not 2015 anymore ventilating the

14
00:01:11,560 --> 00:01:18,479
room the Arya headphones from Phoenix come complete with a cardioid clip mic

15
00:01:16,759 --> 00:01:22,240
and acoustic Chambers constructed entirely of Japanese Pinewood check out

16
00:01:20,640 --> 00:01:27,680
the link in the video description to learn more now as a number of you have noted

17
00:01:25,520 --> 00:01:32,680
on at least several occasions I'm not particularly handy and when it comes to

18
00:01:29,640 --> 00:01:35,360
knock walking out walls and installing

19
00:01:32,680 --> 00:01:40,360
ventilation fans I am not going to be anyone's First Choice as a general

20
00:01:37,280 --> 00:01:44,880
contractor so I have brought in my crack

21
00:01:40,360 --> 00:01:47,520
team Mark and Praxis who are going to be

22
00:01:44,880 --> 00:01:51,520
well helping me with basically doing it for me but before they can do that

23
00:01:49,840 --> 00:01:55,479
there's some stuff I need to do because I've already started using this room as

24
00:01:53,560 --> 00:02:00,880
storage again and I've been informed that all this yes even this that I

25
00:01:58,600 --> 00:02:04,759
worked so hard to put in here has to come out I guess we'll start by

26
00:02:03,280 --> 00:02:08,920
shutting everything down I'm going to have no internet today or

27
00:02:06,719 --> 00:02:14,319
tomorrow how will I live it's like a fish with no internet or water well here

28
00:02:12,080 --> 00:02:19,800
we go I'm just going to have to haul this out of

29
00:02:16,480 --> 00:02:23,560
here my ceiling mounted access

30
00:02:19,800 --> 00:02:26,560
point there we go such winers o we don't

31
00:02:23,560 --> 00:02:28,680
have power o we're running on battery I

32
00:02:26,560 --> 00:02:33,280
don't actually have power in this room so this is a power car that runs through

33
00:02:31,080 --> 00:02:37,360
the wall to uh an outlet and then everything else here is also just kind

34
00:02:35,800 --> 00:02:41,159
of running through that same hole which is just a hole I made in the drywall is

35
00:02:39,319 --> 00:02:44,480
there perhaps while we're redoing these walls is there perhaps a more elegant

36
00:02:42,840 --> 00:02:47,879
way to achieve this well I could actually put outlets on this wall

37
00:02:46,280 --> 00:02:54,720
something I should have done 6 years ago basically yeah yeah yeah okay suggestion

38
00:02:51,040 --> 00:02:57,560
for your lighting LED pot light oh neat

39
00:02:54,720 --> 00:03:02,920
low voltage wow those are really small so the Transformer it only uses 12 WS Al

40
00:03:01,280 --> 00:03:07,319
I'm not going to have like the the incandescent page thing hanging off the

41
00:03:05,560 --> 00:03:13,440
yeah yeah that's it just what you don't like this not really oh well I think I

42
00:03:10,840 --> 00:03:16,760
actually did even put this in myself now that I think about it yeah it was broken

43
00:03:14,799 --> 00:03:25,640
in this room I put this in did I do okay no

44
00:03:21,319 --> 00:03:28,680
oh so I mean this is bizarre I I told

45
00:03:25,640 --> 00:03:31,239
Mark I still had some more of this like

46
00:03:28,680 --> 00:03:35,720
uh particle board with like a primed side stuff and he and I was like yeah

47
00:03:33,439 --> 00:03:41,000
you can you can totally have that we you can put more of it in there he's like

48
00:03:38,519 --> 00:03:45,360
you um so we are going to be ripping all of that out as opposed to just doing the

49
00:03:43,200 --> 00:03:48,720
parts we need to access and drywalling it you can see it's really sturdily

50
00:03:47,280 --> 00:03:52,439
constructed I mean it's not like he's taking it apart with his hands that's

51
00:03:51,200 --> 00:04:00,239
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

52
00:03:57,760 --> 00:04:05,200
good I feel like He-Man just ripping walls apart fun fact never actually seen

53
00:04:03,400 --> 00:04:09,599
an episode of He-Man I don't even know if He-Man is the name of the show He-Man

54
00:04:07,519 --> 00:04:13,159
might just be like a guy on some other show you know what amazing I told Mark I

55
00:04:11,879 --> 00:04:20,680
was going to be here to help today he still brought a helper I can't figure out why inexplicable I took an

56
00:04:17,560 --> 00:04:20,680
electrical course in high

57
00:04:21,479 --> 00:04:29,440
school thank you so uh I'm equipped with

58
00:04:25,680 --> 00:04:31,039
my manly purple mask and my light I'm

59
00:04:29,440 --> 00:04:37,600
going to go find out where those damn Cat 5 cables go to I think it's possible

60
00:04:34,400 --> 00:04:40,800
that they actually go to the uh to the

61
00:04:37,600 --> 00:04:43,160
garage like I think the house was kind

62
00:04:40,800 --> 00:04:48,440
of wired for Ethernet but like not properly so if they go around the front

63
00:04:45,840 --> 00:04:52,280
and across that way then that will be what they were for but it doesn't

64
00:04:50,080 --> 00:04:58,199
actually look like they do one of them goes this way where are you going and

65
00:04:55,039 --> 00:05:01,039
why are you going there e cobwebs ass

66
00:04:58,199 --> 00:05:07,120
sper what the hell I figured out what it is okay they're using it as speaker wire

67
00:05:04,039 --> 00:05:09,600
this is for the um it's for the ceiling

68
00:05:07,120 --> 00:05:14,160
mounted speakers in the living room I don't understand why they're using C 5

69
00:05:11,880 --> 00:05:19,720
for that maybe there's some reason but that explains it okay so that means that

70
00:05:17,479 --> 00:05:26,120
this how the heck did they manage to do a drop unless

71
00:05:22,919 --> 00:05:28,479
oh this goes straight down into that

72
00:05:26,120 --> 00:05:34,039
wall oh that's cool that means if I wanted to run anything else in that wall

73
00:05:30,440 --> 00:05:38,600
than I could and that is also how

74
00:05:34,039 --> 00:05:41,720
they're getting coax in there I think

75
00:05:38,600 --> 00:05:43,680
okay now I get it so now that we've got

76
00:05:41,720 --> 00:05:48,080
everything torn out we've got a clear look at what we're working with and I

77
00:05:45,800 --> 00:05:52,120
can outline exactly what the plan is we're going to pull off of this light

78
00:05:50,440 --> 00:05:55,280
switch box right here and we're going to put an outlet in this room rather than

79
00:05:53,919 --> 00:06:00,840
having me run a power bar through the wall because I'm sure that the fire department would freak out if they saw

80
00:05:58,759 --> 00:06:09,160
that next we're going to install this low voltage uh LED lighting Dad we have

81
00:06:05,280 --> 00:06:10,759
an inline 190 CFM fan which we'll use to

82
00:06:09,160 --> 00:06:15,440
pump air into the room we need to control that with a cooling thermostat

83
00:06:13,240 --> 00:06:21,919
and this is a low voltage connection and this is 120 volt so we need to use a

84
00:06:19,440 --> 00:06:25,520
relay to have this tell the relay what to do in order to tell the fan what to

85
00:06:23,639 --> 00:06:29,960
do okay so basically we're going to climb down into the sopit area down

86
00:06:28,639 --> 00:06:35,280
there where conveniently there are already some ventilation duct things

87
00:06:32,639 --> 00:06:39,160
that are for keeping this uh this insulation up here ventilated and we're

88
00:06:37,319 --> 00:06:43,520
going to put like a service panel in here and just have it create a positive

89
00:06:41,160 --> 00:06:47,240
air pressure situation in this room and then for ventilation out of the room

90
00:06:46,120 --> 00:06:53,599
what we're thinking is we're just going to leave like maybe 6 to 8 in of free

91
00:06:51,280 --> 00:06:59,800
space here in the drywall on the ceiling so that it can just passively exhaust

92
00:06:55,919 --> 00:07:01,720
into the attic just like that so uh we

93
00:06:59,800 --> 00:07:06,000
have a plan it's exactly the plan I would have come up with on my own

94
00:07:03,560 --> 00:07:10,879
too so they're making me vacuum the rodent

95
00:07:07,759 --> 00:07:12,759
poop guess I get that sort of my rodent

96
00:07:10,879 --> 00:07:17,400
poop not theirs so the first step which you can

97
00:07:15,000 --> 00:07:20,879
see practice working on here is using a combination of the included mounting

98
00:07:18,960 --> 00:07:26,440
hardware and a little bit of Fabrication in the sofits to create a mounting point

99
00:07:23,879 --> 00:07:31,319
for the intake fan that's going to cool the room the fan itself uh is free

100
00:07:29,080 --> 00:07:34,800
flowed with with air um so we need to put a damper in so that when you don't

101
00:07:33,319 --> 00:07:40,160
want air flowing in there say in the winter when it's cold you want this

102
00:07:37,960 --> 00:07:46,319
to stop the air flow cool now the last step to make all

103
00:07:43,000 --> 00:07:48,479
of this even have a point at all is to

104
00:07:46,319 --> 00:07:53,199
insulate the ceiling because that is where the heat is coming from from the

105
00:07:50,240 --> 00:07:57,879
Sun hitting the shake roof and basically conducting heat directly into this room

106
00:07:56,240 --> 00:08:01,720
now fortunately this is relatively straightforward because we've already

107
00:07:59,720 --> 00:08:04,919
got strapping right here so we're still going to have enough air flow through

108
00:08:02,960 --> 00:08:09,280
here to keep the wood from rotting but we are going to have to fill it with

109
00:08:06,280 --> 00:08:11,319
insulation and cover it with drywall in

110
00:08:09,280 --> 00:08:15,960
order to make this room effectively part of the house rather than part of the

111
00:08:13,639 --> 00:08:22,319
outside so phase one of the electrical work is actually pretty much done so

112
00:08:19,639 --> 00:08:27,080
we've borrowed 120 volt power from the old incandescent pulley chain light that

113
00:08:24,759 --> 00:08:32,399
used to be up here and we have brought it into this box right here so this is

114
00:08:30,319 --> 00:08:37,519
where the light switch for our new LED light is actually going to go this guy

115
00:08:35,039 --> 00:08:41,880
is going to contain this relay right here as well as this Transformer which

116
00:08:39,640 --> 00:08:46,560
is going to take the 120 volt in and turn it into 24v power that our cooling

117
00:08:44,360 --> 00:08:51,880
thermostat can handle without frying itself whenever the fan engages so

118
00:08:49,480 --> 00:08:55,760
basically what should happen is when the temperature reaches a certain threshold

119
00:08:53,360 --> 00:09:00,680
when it gets too warm it'll connect the circuit and in theory that'll turn on

120
00:08:58,360 --> 00:09:04,880
the fan which as you guys can probably hear is

121
00:09:02,480 --> 00:09:08,839
working just dandy

122
00:09:06,640 --> 00:09:13,440
exciting so for the next stage in the project we're working on putting that

123
00:09:10,680 --> 00:09:17,160
electrical Jack in as well as a better pass through into the room over here the

124
00:09:15,079 --> 00:09:20,560
other update here is that the ducting is now installed so it's pretty

125
00:09:18,760 --> 00:09:26,160
straightforward stuff we've just got some little metal accordion style

126
00:09:23,640 --> 00:09:30,240
ducting here and then some foil tape affixing one duct to the fan on this

127
00:09:28,839 --> 00:09:34,200
side so that that's where the exhaust is going to come into the room and then on

128
00:09:31,959 --> 00:09:37,480
the other end we've got another piece of duct that's going right down to the sfet

129
00:09:36,399 --> 00:09:41,600
where we're going to have to cut a ho for it outside now the clever among you

130
00:09:39,640 --> 00:09:46,640
have probably realized at this point that that is just going to draw air not

131
00:09:44,800 --> 00:09:51,000
only from the outside but also from the rest of the attic where we haven't

132
00:09:48,120 --> 00:09:54,920
insulated and it's going to be quite hot no not so because we're going to jam

133
00:09:53,000 --> 00:10:00,720
some insulation around the edges of it so that it can only draw air from the

134
00:09:57,160 --> 00:10:04,040
outside okay so with the p over most of

135
00:10:00,720 --> 00:10:06,880
the insulation in the walls now and the

136
00:10:04,040 --> 00:10:11,880
drywall mostly well sort of maybe about half up we're ready to do an update

137
00:10:09,480 --> 00:10:16,320
because once this wall is drywalled in this LED light is going to be

138
00:10:13,279 --> 00:10:18,320
permanently mounted so it locks into the

139
00:10:16,320 --> 00:10:23,600
connector a little something like that then we are going to simulate the

140
00:10:21,440 --> 00:10:27,959
switch by joining these wires and there you

141
00:10:25,040 --> 00:10:30,640
go it's an LED light and Brandon's going to have to adjust his exposure oh he's

142
00:10:29,279 --> 00:10:37,519
is going to have to do it again oh he's going to have to do it one more time oh no oh no l is is live with the

143
00:10:34,160 --> 00:10:40,120
light so that's going to go on the

144
00:10:37,519 --> 00:10:44,800
wall so this is a quick status update more than anything else I realized that

145
00:10:42,480 --> 00:10:48,920
the fan is a little on the loud side it's actually audible even through the

146
00:10:46,639 --> 00:10:53,600
wall so what we're going to add is just a simple dimmer switch and we're just

147
00:10:50,639 --> 00:10:56,760
going to tape it up box it inside here and close it away because it's not the

148
00:10:55,160 --> 00:11:00,200
kind of thing that you would adjust very often and the other things that we can

149
00:10:58,560 --> 00:11:04,600
have a look at that have changed since last time is that the fan has been

150
00:11:02,680 --> 00:11:11,560
completely insulated around now so we are getting nice cool air like that is

151
00:11:07,440 --> 00:11:13,800
Frosty air from outside and finally this

152
00:11:11,560 --> 00:11:19,519
puppy has been reframed for a nice big access panel if in the future I want to

153
00:11:16,880 --> 00:11:25,200
run oh I don't know more you know foone lines or coax lines or even power from

154
00:11:23,040 --> 00:11:29,959
my garage or to anywhere else in the house because from here I can access the

155
00:11:27,279 --> 00:11:34,120
entire upstairs and over to the garage now I don't have to

156
00:11:32,120 --> 00:11:40,920
crawl through like I did the other day see much easier so we are pretty much at

157
00:11:37,399 --> 00:11:43,079
the end the room is drywalled and mudded

158
00:11:40,920 --> 00:11:48,040
the access hatch has been mostly created it just needs a bit of a handle on the

159
00:11:44,560 --> 00:11:50,959
outside and check this out this dimmer

160
00:11:48,040 --> 00:11:56,519
switch has been wired in it's kind of a getaway of doing it I know in a perfect

161
00:11:53,519 --> 00:11:59,279
world you know the uh RPM of the fan

162
00:11:56,519 --> 00:12:03,680
would be modulated by temperature as opposed to just by manually doing this

163
00:12:02,040 --> 00:12:08,360
but this is functional since it's the kind of thing that I'm only going to have to set probably once a season

164
00:12:06,120 --> 00:12:14,079
anyway so here's how it works we've got the fan on auto the system is set to

165
00:12:10,360 --> 00:12:16,560
cool and if we turn the threshold down

166
00:12:14,079 --> 00:12:21,600
the cooling fan kicks in but if I kind of go oh gee that's

167
00:12:19,240 --> 00:12:27,440
really loud all I've got to do is before I close up this little access panel turn

168
00:12:24,800 --> 00:12:32,480
that dimmer switch down and we can find the perfect balance between acoustic and

169
00:12:29,639 --> 00:12:37,199
temperatures so finally the last step before benchmarking we've got to put a

170
00:12:34,320 --> 00:12:42,320
grill on the outside air intake which is under the S here preferably one that is

171
00:12:39,760 --> 00:12:47,600
B proof you know so that I don't have bees in my attic thank you for thinking

172
00:12:43,920 --> 00:12:50,320
of that um and then we can Benchmark it

173
00:12:47,600 --> 00:12:53,399
and find out just how well the system works yay

174
00:12:54,160 --> 00:12:58,440
Wheels okay down

175
00:13:03,199 --> 00:13:09,880
so all that's left now is the final

176
00:13:07,399 --> 00:13:14,279
Benchmark so in order to evaluate whether this was a success or failure

177
00:13:11,560 --> 00:13:19,800
because I don't want to just wait around for the summer and for the computers to

178
00:13:16,079 --> 00:13:22,440
all overheat to find out is to look at

179
00:13:19,800 --> 00:13:28,440
what the CPU temperature is under a heavy load relative to the outside

180
00:13:25,720 --> 00:13:33,680
temperature when we're running intensive applications so I'm going to run heaven

181
00:13:31,360 --> 00:13:40,079
in a window as opposed to full screen oops as well as Ida 64 CPU Benchmark in

182
00:13:37,720 --> 00:13:48,839
order to evaluate what it will be like in a worst case scenario with the door

183
00:13:44,880 --> 00:13:51,440
closed with our new cooling system off

184
00:13:48,839 --> 00:13:58,199
and then with the new cooling system engaged and so here you have it guys

185
00:13:54,320 --> 00:14:00,880
this is the result operation cool this

186
00:13:58,199 --> 00:14:06,160
room appears for now to have been a success bringing in cool air from the

187
00:14:03,360 --> 00:14:11,800
outside is going to help a lot to keep this room cool and at the rate that that

188
00:14:08,720 --> 00:14:14,839
fan moves air we are circulating all of

189
00:14:11,800 --> 00:14:17,440
the air in this room like every minute

190
00:14:14,839 --> 00:14:22,680
or so not really giving the systems any time to heat up more than they normally

191
00:14:20,040 --> 00:14:28,320
would well that was fun watching me get burned by the contractor among other

192
00:14:25,880 --> 00:14:32,079
things but you don't have to get burned if you switch over to Ting the mobile

193
00:14:30,279 --> 00:14:37,560
carrier that is focused on customer service and satisfaction first when you

194
00:14:35,160 --> 00:14:41,639
call them this is crazy I actually tried it because I didn't actually quite

195
00:14:39,399 --> 00:14:45,160
believe it when you call them you do not speak to a robot you get put through

196
00:14:43,680 --> 00:14:50,160
directly to a person they answer the phone they're like hello this is Tang

197
00:14:47,480 --> 00:14:54,120
what and the way that their billing works is different from other carriers

198
00:14:52,120 --> 00:14:59,240
you don't have to commit to like 200 talk minutes during Prime hours and blah

199
00:14:56,399 --> 00:15:05,160
blah blah megabytes you pay for only what you use and the average Ting bill

200
00:15:01,519 --> 00:15:06,560
is only $24 per month per device if

201
00:15:05,160 --> 00:15:10,959
you're stuck in a contract and you switch to Ting they'll cover 25% of your

202
00:15:08,519 --> 00:15:15,079
cancellation Fe up to $75 and if you head over to l.com which is linked in

203
00:15:13,240 --> 00:15:19,480
the video description when you sign up at our link you'll get 25 bucks in

204
00:15:16,839 --> 00:15:22,800
service credit or towards a new device and the savings calculator is worth your

205
00:15:21,279 --> 00:15:27,240
time all you do is enter your last few bills from your existing carrier and

206
00:15:25,079 --> 00:15:30,319
Ting crunches some numbers and tells you whether you would save money by

207
00:15:28,480 --> 00:15:34,120
switching to tting so check it out at the link in the video

208
00:15:32,120 --> 00:15:38,360
description so thanks for coming along for this wild ride if you guys disliked
