adam savage here in my cave with a tool
tip
[3]
today it is about electronics
now i use electronics in my
[10]
work you know i i made these lights
a couple years ago they were successful
[16]
um but i am not an electronics guy i
just want to be really clear like i
[21]
understand what a resistor is and what
it does and
[24]
i can give you that waterfall analogy
and water pressure analogy of
[28]
amperage versus voltage and stuff like
that i kind of understand that stuff but
[33]
like i'm not a guy who could design a
circuit and i always need help with this
[37]
kind of stuff whether it's from
jeremy williams or other friends of mine
[42]
uh i'm not an electronics guy
but i have always worked with wiring i i
[48]
don't i mean i understand a lighting
circuit i know that if i have a
[51]
9-volt bulb and have a 9-volt power
supply i know how to wire it through a
[55]
switch
that's pretty straightforward and the
[58]
moment you are doing
that kind of operation wiring a light to
[62]
a switch
you should be the owner of a multimeter
[66]
an electric
electronic multimeter now this is a
[71]
digital instrument
that reads all sorts of aspects of
[74]
electricity and i want to show you
my first multimeter here it is
[80]
this is a fluke model 77 i bought this
in the early 90s at the foothill college
[87]
ham radio electronics swap meet
down off the moody drive exit off of 280
[93]
and i this was
a piece of unobtainium for me in the
[99]
early 90s this is probably
back then this was like a 175 dollar
[104]
multimeter
i i that was that was way more money
[108]
than i could consider
for something like this and i picked
[111]
this up at foothill i think for
40 bucks and
[118]
it's still actually i think the
battery's dead but
[121]
it's still operational almost 30 years
later
[124]
fluke they're i
just have a lot of loyalty with fruit
[129]
greenlee also makes great equipment
something about the yellow of a fluke
[133]
meter that just makes me
super happy uh and fluke still is making
[138]
electric meters um they can tell you
things like
[143]
how much current is going through uh a
piece of electronics you're doing i
[148]
want to find out how efficient that
motor is this can tell you you want to
[152]
find out
the value of a resistor that the
[154]
markings have worn off
on this can tell you want to find out
[157]
how much voltage is coming out of the
wall whether it's ac
[160]
or dc voltage this can tell you again
i'm not an electronics guy and i still
[165]
use these things
all the time but the fact is is that
[169]
flukes
even fluke's entry-level meters can
[172]
still be somewhat expensive so i'm here
for a tool tip
[176]
of an amazing thing i discovered while
making savage builds last year
[180]
and that is this fluke makes like a 50
version a little handheld version
[189]
of their multimeter this thing is
amazing
[192]
i would have killed for one of these in
the early 90s dude
[196]
it's same beautiful color scheme
uh runs on uh two aaa batteries
[203]
uh again i have a lot of loyalty for
fluke because i think i've changed the
[208]
battery on this maybe four times in 30
years like
[210]
seriously they make efficient tools
um notice here this is an artifact of
[216]
using this on television
see those white dots that's covering
[221]
over the name fluke that's the kind of
thing you have to do on
[224]
on on cable television i
as a side note used to drive me crazy
[230]
because you
when a producer sees a logo in camera
[234]
they say hey pa
production assistant will you cover over
[238]
that logo and the pa usually goes
and gets seriously the pa
[244]
will solve this problem like this
they'll get a piece of tape
[247]
and they'll see this logo and they'll
put the piece of tape
[250]
over the logo like this i'm not kidding
i swear to god i've had bas do this to
[256]
me so many times
and then you can't even see what you're
[259]
using the number of
bottles that i'm sure are still in
[263]
jamie's shop where tate went over the
label and jamie doesn't know what's in
[266]
that bottle because when you tore the
tape off it tore the
[269]
okay that's just a total side rant
bonus from this tool tip um
[276]
this is a fluke entry-level multimeter
and i'm here to tell you if you are like
[281]
me
you like you know you do some basic
[284]
wiring and you understand the rudiments
of electronics
[287]
get this this is amazing um and i will
show you
[291]
its most useful feature
continuity what is that well
[298]
if you're working on a circuit and
you're trying to figure out why it's not
[301]
working
[305]
you can tell often that one of the main
reasons it shouldn't work
[309]
sorry how do i say this let's say you
have a circuit and it's a battery with a
[313]
wire to a switch to another wire to a
bulb to a wire
[316]
back to the battery and you wire it all
up
[320]
and it doesn't work well something's
wrong in there
[323]
either your bulb is out or the switch
doesn't work
[327]
or the battery is dead if you make sure
the battery is good
[331]
and you know how do you determine
whether how do you work your way through
[335]
that problem
with continuity um and it goes like this
[338]
continuity is a feature on almost every
multimeter
[341]
you switch it to this little audio sound
and then i think you have on this one
[347]
yeah you have to
there you go uh so you switch it to the
[355]
audio thing you press this button and
now
[357]
when you connect these two leads
[362]
that's called audible continuity and
audible continuity has saved my life so
[368]
many
times so here you go to the switch and
[371]
you touch it
and you can tell whether the switch
[374]
works or not if you
get continuity when the switch is
[377]
supposed to be on then you know the
switch works
[380]
with that light bulb if the filament on
the bulb is out you won't get continuity
[384]
through the bulb
you can workshop your way through a
[387]
circuit or through your car to figure
out where the thing that is supposed to
[391]
be connected into the circuit
isn't audible continuity might be one of
[395]
the
i mean one of the most important reasons
[397]
to own one of these things
that and the beautiful color of yellow
[403]
but
please don't consider anything that i've
[405]
said as in
any way properly instructional about
[409]
electronics
i am a hack uh and not a hacker
[413]
i am a hack and i mostly don't know what
i'm talking about
[416]
but let me tell you audible continuity a
50
[420]
fluke meter this is every bit worth
putting in your kit
[425]
uh thank you guys for joining me for
this one day build
[429]
i'll see you next time this isn't a one
day build i'm on automatic pilot geez
[434]
i'm crow
thank you guys for joining me for this
[437]
tool tip i will see you next time
