1
00:00:04,400 --> 00:00:10,880
if you've ever built your own pc you've probably noticed that most of the

2
00:00:07,520 --> 00:00:13,360
components compact in these shiny bags

3
00:00:10,880 --> 00:00:17,600
these are called esd bags and they exist to prevent the sensitive electronics

4
00:00:15,360 --> 00:00:21,920
inside from getting accidentally zapped by a static charge that built up on your

5
00:00:19,439 --> 00:00:26,400
body when you were doing moonwalking on the carpet or putting on a brand new

6
00:00:24,480 --> 00:00:31,599
tooth from lttstore.com but how dangerous is static electricity

7
00:00:29,679 --> 00:00:36,399
components actually to find out we have arranged the

8
00:00:33,680 --> 00:00:42,320
crossover event of the century and i'm not just talking about the crossover

9
00:00:38,800 --> 00:00:46,320
between his eyebrows we have got the one

10
00:00:42,320 --> 00:00:47,520
the only electro boom in the studio

11
00:00:46,320 --> 00:00:51,760
hi oh my god what are we even doing right

12
00:00:50,000 --> 00:00:55,120
now no no it's a little bit too loud let's

13
00:00:53,520 --> 00:00:59,440
uh do you want to touch it sure oh not really no no no go ahead i i encourage

14
00:00:57,840 --> 00:01:05,199
you first i gotta tell you about our sponsor

15
00:01:02,000 --> 00:01:07,360
see sonic was all too eager to be

16
00:01:05,199 --> 00:01:11,439
involved as soon as we said that i was gonna have this guy here and probably

17
00:01:10,240 --> 00:01:15,439
going to get well hurt

18
00:01:13,600 --> 00:01:18,920
go buy a sea sonic power supply if you support this endeavor

19
00:01:26,080 --> 00:01:31,759
i'm the kind of person that doesn't even like to lick a 9-volt you know to see if

20
00:01:29,920 --> 00:01:34,799
it's charged because it's like is it worse than that yeah man come on touch

21
00:01:33,360 --> 00:01:40,880
it oh oh that's fine see see you're scared

22
00:01:38,720 --> 00:01:44,640
for no reason well i'm not scared for no reason i've watched your video

23
00:01:42,960 --> 00:01:48,159
well it's low power i can increase the power i saw your electric guitar

24
00:01:46,799 --> 00:01:52,799
that's the music channel burner now bring it close you feel it not at all

25
00:01:50,399 --> 00:01:56,320
probably tell me why that is

26
00:01:54,399 --> 00:02:00,159
the reason is that instead of the arc going through a single point on your

27
00:01:58,000 --> 00:02:03,360
skin it's going over a large surface in your hand so

28
00:02:01,280 --> 00:02:07,360
it spreads out you don't feel it i can actually increase the power now a little

29
00:02:04,880 --> 00:02:11,440
bit maybe feel it

30
00:02:08,640 --> 00:02:16,080
no actually there you go ultimate power

31
00:02:14,480 --> 00:02:22,480
let's try something let's do the same thing with that oh sure

32
00:02:18,800 --> 00:02:25,280
and i increase the frequency again

33
00:02:22,480 --> 00:02:28,400
now let me see if it jumps to me oh oh my god

34
00:02:26,959 --> 00:02:32,879
yeah why why does it hurt when you do it so

35
00:02:31,040 --> 00:02:37,519
it's just because it's a very small it's a point yeah it's more on a single nerve

36
00:02:35,200 --> 00:02:40,720
rather than spreading over a big surface but then

37
00:02:38,400 --> 00:02:44,720
this is not the same as the static discharge that we worry will kill our

38
00:02:43,120 --> 00:02:48,480
our RAM stick while we're installing it is it no it's not uh how do we how do we

39
00:02:47,280 --> 00:02:54,080
simulate esd that would be with a special gun

40
00:02:51,280 --> 00:02:57,840
called the esd gun so this is it then yes that's okay that's how you break it

41
00:02:56,000 --> 00:03:02,800
and all it does is simulate like a finger touching something yeah yeah so

42
00:03:00,319 --> 00:03:06,959
it's basically for humans handling electronics simulating that

43
00:03:05,200 --> 00:03:09,840
and then what else we got in here this is the gun

44
00:03:08,879 --> 00:03:17,120
with the long cable and these parts we can censor that i

45
00:03:14,959 --> 00:03:21,280
think i just saw a robot dildo and that's where it goes

46
00:03:19,599 --> 00:03:27,200
before anyone gets upset by the way the electronics that we're going to be sacrificing today are from free geek a

47
00:03:24,879 --> 00:03:32,400
local electronic salvager that says yes these are working but no these are not

48
00:03:30,400 --> 00:03:37,760
valuable parts that anybody would want integrated into a salvage pc so

49
00:03:35,840 --> 00:03:41,200
go ahead and kill it we'll take it right back and make sure that it gets recycled

50
00:03:39,360 --> 00:03:45,280
properly do you want to try this one and see how it feels

51
00:03:42,799 --> 00:03:48,640
um okay yeah that's fine it was like a duller pain

52
00:03:46,959 --> 00:03:52,720
i don't know more shocking more shocking yes yes why

53
00:03:50,239 --> 00:03:57,840
well it is dc and it is like the duration of the pulse is longer so it

54
00:03:55,280 --> 00:04:01,680
could feel actually it could hurt more compared to the tesla coil that's why i

55
00:03:59,760 --> 00:04:04,799
asked you before and you didn't answer me properly you just said yeah it

56
00:04:03,120 --> 00:04:08,480
depends and then you pointed a gun at me i can put a higher voltage if you want

57
00:04:06,720 --> 00:04:13,120
or are you okay with 12 kilowatts i don't know sure you tell me

58
00:04:11,120 --> 00:04:18,560
okay i'll put 25 let me know how it feels 25 kilowatt discharge to live okay

59
00:04:19,040 --> 00:04:25,680
feel the pain again ah okay go ahead ah okay no it's fine i can't make it lethal

60
00:04:24,080 --> 00:04:28,880
unfortunately but here that's very helpful to know what kind of voltage

61
00:04:27,199 --> 00:04:32,400
could i build up on my body while i'm just walking around my house before i

62
00:04:30,479 --> 00:04:35,919
build my computer at home you usually pick up 8 to 12. if you build your

63
00:04:34,639 --> 00:04:39,520
computer you just want to ground yourself with a proper strap right you

64
00:04:37,680 --> 00:04:44,400
don't you don't want to have any charge on you because like rams

65
00:04:41,680 --> 00:04:50,800
or internals of the computers components ics chips they are usually rated for two

66
00:04:47,680 --> 00:04:52,720
kilovolts maximum that's it now i always

67
00:04:50,800 --> 00:04:58,400
ground myself correctly when i'm working on our projects that's what he says

68
00:04:55,040 --> 00:05:01,040
ow ah it shocked me ow you know let's

69
00:04:58,400 --> 00:05:05,360
say hypothetically i've had situations where i've gone to pick up a RAM stick

70
00:05:03,120 --> 00:05:08,639
and i have actually felt the ark but the RAM stick did turn out to still work how

71
00:05:07,600 --> 00:05:12,160
could that be imagine all of us are standing on earth

72
00:05:10,800 --> 00:05:18,560
right if a meteorite hits you on the head you die

73
00:05:15,680 --> 00:05:22,639
but if the meteorite hits the earth the whole earth shakes a little bit everyone

74
00:05:20,560 --> 00:05:27,360
on earth is fine right it's the same thing on the ground here when you hit

75
00:05:24,320 --> 00:05:29,600
the ground the whole

76
00:05:27,360 --> 00:05:33,360
board moves together right the voltage on the board

77
00:05:31,600 --> 00:05:38,720
everything moves together but if you hit a certain weak spot

78
00:05:35,600 --> 00:05:41,680
then so it's dead if you managed to not

79
00:05:38,720 --> 00:05:46,560
kill a component with an esd discharge you got lucky yeah pretty much yes

80
00:05:45,520 --> 00:05:52,800
now you want to kill it zap that way hold on a second

81
00:05:50,320 --> 00:05:56,160
should i be holding it while you do that let's see what happens well hold on a

82
00:05:54,479 --> 00:05:59,120
second okay fine

83
00:06:00,479 --> 00:06:07,360
oh you shouldn't hold it you knew that was gonna happen exactly but you have to learn your

84
00:06:05,280 --> 00:06:11,840
lesson the hard way so i had to do it is it helpful or does it hinder that i'm

85
00:06:10,080 --> 00:06:15,280
touching it when you zap it no it actually makes it worse it makes it

86
00:06:13,520 --> 00:06:18,080
worse because when i zap it it goes to your body so there is a path depending

87
00:06:16,800 --> 00:06:21,520
on where you touch it could actually kill me it might already be dead

88
00:06:20,080 --> 00:06:25,840
actually only one way to find out

89
00:06:23,440 --> 00:06:30,080
when i discharged it at 25 kilowatts uh i think we killed it sir

90
00:06:27,759 --> 00:06:36,319
is it dead it it appears to be dead as a doornail the play doesn't have a oh

91
00:06:33,520 --> 00:06:40,479
sorry so the case does work as a ground now we know because i felt that not just

92
00:06:38,560 --> 00:06:46,400
on my back but also in my finger that's why they say pain is nature's teacher

93
00:06:44,160 --> 00:06:50,160
got my eye on you okay let's not kill them so quickly this time so to give

94
00:06:48,479 --> 00:06:55,120
this a chance of surviving what should we do uh don't hold it in your hand oh okay uh

95
00:06:53,680 --> 00:07:00,840
and are you gonna do the same voltage again it's 12 kilovolts now see all this area

96
00:06:58,720 --> 00:07:05,599
behind it is ground so let's zap that ready uh yeah i'm ready see it doesn't

97
00:07:03,759 --> 00:07:08,720
jump as much anymore yeah i see that it's only ddr2 but it's hard to watch

98
00:07:07,520 --> 00:07:14,720
but now that you touched it you might have killed it oh damn it ah it's alive huh

99
00:07:12,720 --> 00:07:18,960
yes good hey all right the system works Linus didn't

100
00:07:16,960 --> 00:07:23,759
kill it you were involved no no no no no you don't put it on me so

101
00:07:21,520 --> 00:07:30,840
just to be clear they do esd testing on a finished product not on the internal

102
00:07:26,160 --> 00:07:30,840
component on the casing okay

103
00:07:30,880 --> 00:07:38,800
wasn't me it was him so is there a way for me to simulate what we did the first

104
00:07:36,400 --> 00:07:43,440
time but with my body instead of with the gun i have to keep charging you so

105
00:07:41,840 --> 00:07:48,240
wait wait hold on we need to have a plan okay you don't even have the RAM stick on hand ready so i don't want to be i

106
00:07:47,039 --> 00:07:54,240
don't want to be doing this any longer than we have to okay so so you tell me when it's time actually

107
00:07:52,080 --> 00:07:59,120
no you can just move the stick to touch me when you think it's good if it

108
00:07:55,680 --> 00:08:01,680
doesn't stop jumping let me know

109
00:07:59,120 --> 00:08:04,400
stop jumping yeah stop jumping good now you're charged

110
00:08:04,639 --> 00:08:11,199
that was a proper human simulation i guess we are booting but that clearly

111
00:08:08,720 --> 00:08:15,120
took longer right with stranger behavior than before should we see what happens

112
00:08:13,199 --> 00:08:19,759
if we hit it again sure okay a different pin

113
00:08:17,840 --> 00:08:23,599
sure we want it to go off of what we hope is a data pin right right so then

114
00:08:21,919 --> 00:08:29,280
you should you should touch this part yeah okay so i'll hold it like this okay

115
00:08:26,400 --> 00:08:33,279
all right ready charge me sure is it is it good yeah

116
00:08:31,360 --> 00:08:39,200
okay you're trying i'm fully charged fully charged and i'm gonna touch one of

117
00:08:34,959 --> 00:08:40,719
these ouch oh is it running yeah okay

118
00:08:39,200 --> 00:08:45,839
then unplug it let's try it one more time okay so tell me something if it

119
00:08:43,519 --> 00:08:49,920
arcs anyway could we have it arc through a chip no not through the chip because

120
00:08:47,839 --> 00:08:53,440
this plastic stuff is quite uh non-conductive it will block the esd

121
00:08:52,000 --> 00:08:57,600
it'll probably go around it hitting something else got it already then well

122
00:08:55,519 --> 00:09:01,200
let's just let's just hit it then yeah just let's just feel the pain how long

123
00:08:59,360 --> 00:09:06,000
how long should we go i don't know man

124
00:09:03,760 --> 00:09:10,560
this is five hertz yes all right and it's gonna hurts

125
00:09:08,399 --> 00:09:14,050
yeah okay very good okay oh let's go ready wait wait oh my god is that what

126
00:09:12,560 --> 00:09:21,120
you're going to do yes kate oh my god

127
00:09:16,959 --> 00:09:24,959
if it's not dead it's quite a strong RAM

128
00:09:21,120 --> 00:09:27,120
oh holy [ __ ] it is back maybe it going

129
00:09:24,959 --> 00:09:30,640
through our body loses some of its power so it's much milder on the RAM what you

130
00:09:29,200 --> 00:09:34,320
can do is do just leave the board on your hand and i just zap the board right

131
00:09:32,480 --> 00:09:39,120
on the chips and see what happens like this oh or charge you and zap with

132
00:09:37,279 --> 00:09:42,160
my finger let me know if it hurts more when i zap here

133
00:09:40,720 --> 00:09:48,880
wait where are you zapping probably going to hurt more probably yeah i just

134
00:09:44,880 --> 00:09:48,880
okay i'll zap you and was that forever

135
00:09:49,120 --> 00:09:54,320
okay good fine ready oh my god

136
00:09:55,680 --> 00:10:01,920
oh my god it better be dead now

137
00:09:59,279 --> 00:10:06,480
damn it bloody hell it's posting wow this is some good RAM we can break it in

138
00:10:03,839 --> 00:10:11,200
half forget it then that module is magic in the meantime let's try another module

139
00:10:08,560 --> 00:10:14,160
so let's try to kill this one through us so that's this will be our last attempt

140
00:10:12,800 --> 00:10:18,880
at that okay 12 kilowatts

141
00:10:16,240 --> 00:10:24,959
charged how could you

142
00:10:20,640 --> 00:10:28,000
where are you how could i i trusted you

143
00:10:24,959 --> 00:10:28,000
you did no such thing

144
00:10:28,079 --> 00:10:34,720
okay that works fine what we've learned so far is that the weakest discharge to

145
00:10:32,640 --> 00:10:38,640
the module was when it was just sitting on the table because it's not grounded

146
00:10:36,480 --> 00:10:42,720
to anything and it reaches equilibrium very quickly

147
00:10:39,839 --> 00:10:46,079
then we have a human hold it and we get a much stronger discharge so that's

148
00:10:44,560 --> 00:10:50,959
because of the capacitance of the human body right yeah you have a much body of

149
00:10:48,160 --> 00:10:55,360
charge to transfer electricity but we can make it much stronger by grounding

150
00:10:53,279 --> 00:10:59,519
the human body so the charge passes much more easily through it

151
00:10:57,200 --> 00:11:03,839
um so that's what you so wait really this is your method okay so we've got a

152
00:11:01,360 --> 00:11:07,680
ground to your wedding ring and then we're gonna charge you with this one and

153
00:11:05,279 --> 00:11:11,760
then touch it with that one okay ready here we go oh my god

154
00:11:10,320 --> 00:11:18,399
ready where should i touch oh my god

155
00:11:15,920 --> 00:11:23,519
that was much more painful what the hell it's not dying we go

156
00:11:21,200 --> 00:11:26,880
through so much pain for nothing who designed this stupid RAM well how

157
00:11:25,279 --> 00:11:31,360
did we kill the first one did we just get lucky i think so

158
00:11:29,839 --> 00:11:35,839
we have a new plan what's the new plan so we're gonna

159
00:11:33,440 --> 00:11:39,760
connect it directly to ground so we won't feel pain the problem is that

160
00:11:37,600 --> 00:11:43,600
because we are in pain we let go quickly we connect it to ground and just zap it

161
00:11:41,519 --> 00:11:47,680
directly and hopefully it'll kill it ready

162
00:11:45,360 --> 00:11:47,680
die

163
00:11:49,680 --> 00:11:59,360
okay you think it's different i think it's dead i think it's dead is it coming up

164
00:11:55,120 --> 00:11:59,360
hold on no no i think it's dead

165
00:12:00,240 --> 00:12:05,519
just because we had to create such a contrived scenario in order to kill the

166
00:12:04,160 --> 00:12:10,399
memory module doesn't necessarily mean that you just

167
00:12:08,480 --> 00:12:13,360
shouldn't worry about electrostatic discharge

168
00:12:11,680 --> 00:12:17,680
let's show you something different this more realistic scenario is not that

169
00:12:15,519 --> 00:12:20,959
different from what electroboom just set up on the table

170
00:12:19,279 --> 00:12:25,760
because the module is plugged into a computer that is plugged into the wall

171
00:12:23,040 --> 00:12:31,600
it is grounded in a very similar manner now what we don't know is whether or not

172
00:12:29,040 --> 00:12:36,079
our lead was actually connected to like a data pin and obviously here none of

173
00:12:34,399 --> 00:12:40,720
the data pins would be grounded in that manner but this is still

174
00:12:38,480 --> 00:12:46,320
sorry but this is still way more realistic and

175
00:12:44,000 --> 00:12:51,600
not that different from what we just did so to test it we're going to charge me

176
00:12:49,200 --> 00:12:54,639
up and i'm going to so i don't know give me five hertz and

177
00:12:53,279 --> 00:12:59,120
then i'll reach in and take out the module how about one hertz

178
00:12:56,800 --> 00:13:02,560
one here so okay you are weak that way on okay sure

179
00:13:02,560 --> 00:13:10,639
okay yeah oh okay okay

180
00:13:07,600 --> 00:13:12,560
okay oh screw it let's just go

181
00:13:10,639 --> 00:13:18,000
dang it okay okay so the point of that exercise

182
00:13:15,519 --> 00:13:23,680
was to simulate me working in a very careless environment building up charge

183
00:13:20,720 --> 00:13:27,200
on my body while i'm working on the pc is that is that very reasonable that's

184
00:13:25,519 --> 00:13:30,639
right yeah okay but as you also saw it's very hard to

185
00:13:29,279 --> 00:13:35,360
get inside without touching anything else unless you're working on an open

186
00:13:33,120 --> 00:13:38,959
test bench for example in which case this is totally realistic i really don't

187
00:13:37,680 --> 00:13:41,200
want to do this again i really hope it's dead

188
00:13:44,480 --> 00:13:50,959
so how do we kill it with a finger oh yeah we could have it running yeah okay

189
00:13:48,959 --> 00:13:54,000
if the computer may crash it might not die though you might have to restart the

190
00:13:52,320 --> 00:13:58,240
computer and it comes back up all right here we go you wanna ground yourself

191
00:13:56,160 --> 00:14:01,519
first and i zap you with 25k and see how it feels

192
00:13:59,440 --> 00:14:05,920
not really it's a good opportunity for a good opportunity for

193
00:14:04,079 --> 00:14:11,199
a good opportunity okay well i actually okay can i have 15

194
00:14:09,040 --> 00:14:15,360
let's do 20 first ready where should i zap i don't know man ready

195
00:14:15,440 --> 00:14:20,399
okay you go straight for the super

196
00:14:18,720 --> 00:14:24,480
this is where you're supposed to check the baby's milk okay make sure it's not

197
00:14:22,639 --> 00:14:29,440
too hot he goes straight for the most sensitive spot on the heart that's the

198
00:14:26,079 --> 00:14:32,079
sensor for that purpose i'm on to you

199
00:14:29,440 --> 00:14:34,959
it wasn't super painful more shocking right

200
00:14:34,959 --> 00:14:39,040
so okay give me 25 give me 25.

201
00:14:39,279 --> 00:14:45,120
oh that one i could actually feel muscle contraction a little bit like that's

202
00:14:42,800 --> 00:14:50,639
good that's more oh yeah like one more no not just yet okay so here's what

203
00:14:47,120 --> 00:14:50,639
we're gonna do i'm gonna

204
00:14:51,279 --> 00:14:56,320
ground it try to bring your hand as close as

205
00:14:54,639 --> 00:15:00,880
possible to the data lines at the bottom maybe oh okay

206
00:14:58,560 --> 00:15:04,320
okay well hold on hold on wait

207
00:15:01,839 --> 00:15:07,040
i can't contain myself okay just a second

208
00:15:05,199 --> 00:15:10,880
just a second just a second

209
00:15:08,959 --> 00:15:17,199
i'm gonna charge your body and see what happens okay

210
00:15:14,480 --> 00:15:21,199
that was that was powerful nice okay how do you feel now i don't know if i got

211
00:15:18,880 --> 00:15:25,600
the RAM though you gotta be freaking kidding me

212
00:15:23,600 --> 00:15:28,560
see that's why they put all these grounds

213
00:15:26,800 --> 00:15:31,920
exposed right in the way of your touching so that it always jumps to

214
00:15:30,079 --> 00:15:36,399
ground first before anything else good design

215
00:15:33,199 --> 00:15:38,800
but it felt like it actually hurt more

216
00:15:36,399 --> 00:15:42,160
when it dumped multiple times why would that be

217
00:15:40,480 --> 00:15:45,760
well maybe because you were jumping directly to ground but i was jumping

218
00:15:44,240 --> 00:15:49,759
directly to ground when i was holding the ground let's see this was on one

219
00:15:47,279 --> 00:15:55,040
hair so maybe it was keeping it was charging you every time so you forgot to

220
00:15:52,800 --> 00:16:00,000
change it was i supposed to change it well i was only supposed to zap it once

221
00:15:57,120 --> 00:16:03,440
okay that explains why it hurts so much yeah but if i don't put it on one hair

222
00:16:02,160 --> 00:16:07,680
it just jumps to you once it doesn't charge you anymore you lose charge right away

223
00:16:05,680 --> 00:16:12,240
we could still directly discharge no wait wait

224
00:16:08,880 --> 00:16:14,079
okay i want to kill it with a finger

225
00:16:12,240 --> 00:16:20,560
after this you might have to go to a consultation electro boom

226
00:16:16,800 --> 00:16:23,560
therapy exactly right do it okay 20

227
00:16:20,560 --> 00:16:23,560
kilovolts

228
00:16:24,480 --> 00:16:31,560
okay no no hit me again

229
00:16:28,079 --> 00:16:31,560
oh my god

230
00:16:37,040 --> 00:16:39,360
ow

231
00:16:40,240 --> 00:16:45,920
it's alive no it's dead yeah

232
00:16:43,600 --> 00:16:50,720
[ __ ] you well reset your computer maybe the RAM

233
00:16:47,759 --> 00:16:54,720
is fine it's just crashed oh that is possible

234
00:16:52,320 --> 00:16:59,279
messing with data lines will crash your computer but doesn't necessarily mean

235
00:16:56,880 --> 00:17:01,680
that your RAM is dead so you we see is it back

236
00:17:02,320 --> 00:17:05,560
it's alive

237
00:17:07,120 --> 00:17:13,360
i can't do that again was that 20 or 25 20. oh

238
00:17:11,120 --> 00:17:16,799
my finger's like a little bit

239
00:17:14,559 --> 00:17:20,640
lost sensation yeah after a while it gets a little numb fine

240
00:17:18,640 --> 00:17:25,360
i do want to use the gun now oh okay there i have the score to settle

241
00:17:22,559 --> 00:17:29,760
it's ready now how do you know for sure no stop touching i didn't even get you

242
00:17:28,000 --> 00:17:32,400
well i was quick yeah okay it's working so that's one

243
00:17:31,520 --> 00:17:36,799
hertz okay well that's why i couldn't get you because it was way just at 12. i was

244
00:17:35,679 --> 00:17:40,640
thinking i was going to get you right away like i got yeah you have to get much closer like i got like this

245
00:17:39,360 --> 00:17:44,559
distance away and i thought it was good oh my god damn it

246
00:17:43,039 --> 00:17:51,600
all right i deserved that problem you did 100 okay

247
00:17:47,919 --> 00:17:53,440
oh okay well that was more immediate

248
00:17:51,600 --> 00:17:57,520
yeah computer crashed right away but again might just be a crash you got to

249
00:17:55,760 --> 00:18:04,320
be kidding me restarted that's a graceful ish crash

250
00:18:01,200 --> 00:18:06,000
well it's still alive somehow i think if

251
00:18:04,320 --> 00:18:11,679
you go from the side here you can walk that side okay all right does that look good yeah

252
00:18:10,080 --> 00:18:17,200
what nothing move it around

253
00:18:14,960 --> 00:18:21,280
for the love of god die no signal please check your input who's

254
00:18:19,200 --> 00:18:24,880
that the motherboard or the RAM when the RAM is in you zap the data lines it's

255
00:18:22,960 --> 00:18:27,919
also going directly to the rest of the motherboard right

256
00:18:26,640 --> 00:18:31,440
but the fact that the motherboard is giving us a beep code is a good sign

257
00:18:30,000 --> 00:18:34,640
that means the motherboard has at least initialized and knows hey there's some

258
00:18:33,600 --> 00:18:40,240
problem that doesn't mean though that the entire

259
00:18:36,720 --> 00:18:43,039
motherboard is working yeah all right

260
00:18:40,240 --> 00:18:48,960
this should be good okay it's alive yeah i think so kill the RAM okay good

261
00:18:45,520 --> 00:18:50,720
i am impressed by the resiliency of

262
00:18:48,960 --> 00:18:54,000
everything we tried today

263
00:18:52,000 --> 00:18:58,480
my finger is still a little numb i'm impressed by your resiliency i do my

264
00:18:56,640 --> 00:19:02,640
best anything for science i guess anything for the viewers

265
00:19:00,679 --> 00:19:05,600
ltcstore.com come on help me out here guys make it worth it yeah did you see

266
00:19:04,080 --> 00:19:10,000
the pain you have to buy his merch now buy a hoodie at this point i'm ready to

267
00:19:08,240 --> 00:19:14,440
kind of draw a conclusion here electrostatic discharge can it kill your

268
00:19:12,080 --> 00:19:17,840
sensitive electronic components abso-frequently

269
00:19:16,000 --> 00:19:22,160
i mean they wouldn't put warning labels on the things if there wasn't a chance

270
00:19:19,840 --> 00:19:27,039
that it was going to be destroyed but on the other hand in the real world

271
00:19:24,880 --> 00:19:31,280
is it necessarily a guarantee that if you forget your esd strap one time that

272
00:19:29,520 --> 00:19:36,080
you're gonna kill something by touching it probably not yeah not that often but

273
00:19:34,240 --> 00:19:39,600
you're rolling that die every time you don't ground yourself

274
00:19:38,160 --> 00:19:46,240
correctly while you're working on your components and if it does it's going to be an expensive failure right exactly so

275
00:19:43,760 --> 00:19:50,240
it comes down to what are you working on are you working on some old refurb thing

276
00:19:48,640 --> 00:19:54,400
where replacing the RAM is going to be literally two dollars then you know what

277
00:19:52,480 --> 00:19:59,760
i probably wouldn't inconvenience myself if i'm working on the latest rtx 3090

278
00:19:56,880 --> 00:20:03,760
that cost 1500 and i can't even replace if i did kill it

279
00:20:01,679 --> 00:20:10,080
i'm gonna be real super careful from now on that's my promise

280
00:20:07,280 --> 00:20:12,559
just like i promised to my sponsors to uh

281
00:20:10,880 --> 00:20:16,400
expressvpn what what's going on here this is my

282
00:20:14,240 --> 00:20:20,400
sponsor this is my show i have a sponsor too you know this is my sponsor fine

283
00:20:18,400 --> 00:20:26,080
i'll do mine at home see sonic power supplies high quality long warranties

284
00:20:22,720 --> 00:20:28,080
great efficiency and uh you know hey if

285
00:20:26,080 --> 00:20:31,760
you opened up the chassis and touched the internal components i'm sure it

286
00:20:29,840 --> 00:20:35,440
would zap you real good but that's not really a that's not really a feature

287
00:20:33,919 --> 00:20:38,960
don't do that that would legitimately probably kill you so

288
00:20:37,280 --> 00:20:42,400
go check out csun and get the link in the video description

289
00:20:40,400 --> 00:20:46,720
i might have wimped out but electro room told me that he's actually planning a

290
00:20:44,240 --> 00:20:52,320
follow-up video on his channel where he is going to continue to try to kill the

291
00:20:49,600 --> 00:20:55,520
stick with a finger so make sure you're subscribed we're going to have a link in

292
00:20:53,440 --> 00:20:58,000
the video description so you don't miss that
