DIY Privacy Display - Recycle your monitors in a badass way

so there's this really cool kind of

trick effect that you can do with an LCD

or LED monitor where you remove the

polarizing filter and then mount a

polarizing filter into a pair of glasses

very easy to do with some 3d glasses

that results in a monitor that looks

like it just emits white and nothing

else but if you're wearing the right

glasses you actually see what's on

screen let's check it out

10 keyless compact keyboard with

multiple Cherry MX switch variants as

well as 30 macro keys with five profiles

description to learn more so this isn't

an original Linus tech tips idea this

was posted by two different people about

two years ago on YouTube it was posted

by BrussPup and on Instructables it was

posted by de movi and there's also two

different methods of doing this they

both start with taking off the bezel of

the monitor and then using a knife to

cut a perimeter around the screen it's

very sketchy but oh well

and then by chiseling off the polarizing

filter getting rid of the glue somehow

with a solvent of some sort and then

mounting a polarizing filter in a pair

of glasses sounds pretty straightforward

so far the differentiating part is

whether or not you buy some polarizing

filters or reuse the polarizing filter

off of your screen buying them sounds

like more of a sure shot so I made sure

that I had some before we started this

but we're going to see which one works

best and we're going to go through the

whole process on camera okay so first

things first I need to clear this area I

need to get my eye fix it kit ready and

my screwdriver because I have to tear

the bezel off of this guy I'm going to

remove the stand one interesting tidbit

I've already kind of done this I used a

different monitor and it's super didn't

work and you might be wondering why I

would release this video if it like

super failed once already the problem

there was there was a pre-existing crack

on the monitor so when I'm trying to

pull off the polarizing filter this glue

under there the pre-existing crack

spreads and I just ripped the whole

thing in half so hopefully it doesn't

happen again and if not we'll probably

be good removing bezels on monitors kind

of super sucks I'm going to do something

that's not super visually appealing and

use just a flathead to pry it off

realistically you're supposed to use a

spudger but I just bent the whole head

off of one of mine because it wasn't

really working properly the problem with

this guy and the reason why it's going

to be pretty ugly is it's metal and it

doesn't give it all might be night

if you have something plastic so we can

give a little bit I might end up messing

up some of the plastic here so what I'm

going to do is start on the bottom that

way it's hopefully going to be the least

viewed part of the monitor

and see look at this my proper prying

tools don't really seem to be surviving

I just torqued the whole end off of that

one so rip I guess I'll go back to using

my probably not going to be as pretty

but screwdriver trick I ended up

starting on the top because the bottom

was giving me too much troubles you can

see the starting point is pretty rough

actually that's why I suggest maybe

taking a little bit more time with it

using a more proper tool and then from

there on it's not too bad they'll just

see little bumps here in there from the

flathead but it's not really the end of

the world I know people will care and it

will bug me so whatever

okay bezel is hopefully off what is

going on down here

oh dear hey some cables go to the

buttons I was kind of hoping that these

were just going to be button plates and

the actual button was going to be under

them and not on the bezel that is not

true as you can see the whole mechanism

is in here and then it goes through a

wire into the thing so I'm not actually

gonna be able to get this out which

super sucks

oh no yeah I'm not gonna really get it

out so I'm gonna have to get a support

for it and then I'll be able to work

around it one little tidbit that I

recommend I learned from the last

monitor that your initial perimeter cut

is actually pretty important I would

recommend a sturdier hopefully bit

sharper knife for the actual perimeter

because you want a nice clean cut

if that part makes it in the video

everyone's going to spear me for cutting

towards myself so right now I'm just

trying to connect the corners so I cut

for perimeter lines but they don't

necessarily completely match up so I'm

just trying to bridge them okay so our

perimeter lines have been cut we're

mostly done with the nice big knife now

what we need to do is try to get under

those lines that we cut and start

actually pulling up the polarizing

filter now remember there is glue under

this entire thing so while you can pull

it up sometimes you do really need to

chisel under there and separate the

polarizing filter from the actual panel

so the reason why you want a nice clean

cut with probably a nicer knife around

the perimeter is once you kind of get

started with your chisel as you go along

the side where you cut should just kind

of clump oh that bird shouldn't go in

the video that's bad I was just

commenting about how I shouldn't be

cutting towards myself

so the reason why you want a nice clean

cut with your probably sharper knife

around the perimeter is so that when

you're moving along with the chisel the

perimeter actually comes up so as you

can see here I'm pushing in and then

sliding out angling a little bit pushing

in again and just moving along and the

perimeter should just kind of come up

with my knife which is actually quite

helpful so that it keeps a clean edge

when you enter the first time with your

chisel it's probably going to be a

little bit messy but once you start

going everything does get easier another

helpful trick is to not necessarily pull

the polarizing filter all the time and

time to kind of rip it off but hold it

up so you get your chisel under there

more easily once you have some room like

I do now it's much easier to do this at

the beginning obviously that's not

really going to work so I've got this

whole side off and I've got a bit of the

top and a bit of the bottom off it

starts to go a lot faster now I will

note this might not be the experience

with every monitor I do believe the

amount of glue used on each monitor is

definitely different

but with this one it is going quite a

bit faster another thing that's helping

me is the clean sharp cut that I got all

the way around the monitor which will

feel super sketchy while you're doing it

but is actually totally fine so don't

worry about it so up here it started to

break a few times yeah I don't really

know what's going on with that probably

something's wrong with the cut I do

notice there's some strand of something

here so what I might do is grab the

knife that I originally did the

perimeter with and kind of rerun this

area a little bit just to make sure that

it's actually okay so this top bit for

me is pretty rough I keep getting cracks

constantly going down from the top but

my bottom line is super clean so

hopefully I'll have a lot of usable

filter and kind of this area and I'll

just have to ignore the top left I guess

almost let go come on there we go okay

so there's our polarizing filter we've

got kind of an ugly entry here where I

started and then some big cuts up here

which are pretty unfortunate but I have

a lot of usable space to cut out lenses

to replace on here or there the other

method which I'm also going to do which

is where we have purchased polarizing

filters for like I don't know not that

much off of Amazon and we'll try each

method see which one's better so just a

note is that this stuff on the screen

isn't actually slashes or cuts into the

screen this is all just glue residue so

I need to clean it up somehow hopefully

I can use isopropyl alcohol because

that's all I really have on hand but I

know people have been using goo begone

so we'll see what has happened there

hey do we have goo be gone do we have

goo be gone but I have been using a

shirt because the paper towel was

leaving a whole bunch of crap behind and

I wouldn't recommend that if you

actually ever want to wear the shirt

again so just a note Wow okay so yeah

using a proper thing that is designed

for removing glue probably a good idea

this is so much easier so one thing I

would recommend is making sure that you

let your whatever goo removal stuff you

use to sit for probably a while and then

kind of pad it off and take it off

nicely and then do it again and let it

sit and do it again and let it sit and

just keep on doing that to the point

where you can fairly easily just wipe

the glue off I as you guys saw use the

chisel blade which was recommended on a

few guides online saying that the blade

definitely wouldn't scratch the monitor

but there are lines going along the

monitor that you can see from just the

edge of the knife so a little bit just

point in that and yeah try to make sure

that your solvent solution does more of

the work than you do and I think we'll

be fine we're going to call it quits

there in terms of trying to touch up the

panel I'm going to try to get this

monitor back together I knew those wires

were going to be a problem all right

one thing again to take note of is you

can do this with pretty much whatever

panel you want but I recommend going my

route and buying some kind of cheap

panel off some dude who's moving on

Craigslist because it's not a perfect

method but we'll talk about that more

later now what we need to do is plug

this guy in make sure it's all white

which I'm sure it will be and then check

out the alignment for these filters so I

can cut them into some glasses can you

even see that right you want to plug the

lan show computer

okay so it works a kind of frustrating

thing happened while we were going

though nothing went wrong with the

actual removal of the polarizing filter

or anything but it seems like the

inverter on the monitor has ripp died at

some point in time so if I shove this

guy on here and change the source you'll

see it works but then goes away almost

immediately so we're going to go through

the rest of it I'm going to make some

glasses I'm going to test some things

but pretty disappointed at the monitor

died so I'm going to have to kind of

rotate trying to turn this thing on and

then try to figure out what orientation

these things need to go before I cut

them oh that's really close yeah

yeah that's good so now I know from does

not letting go of it that this part

needs to be going up use my lens that I

popped out of my glasses earlier squish

that kind of against the polarizing

filter and I'm going to use a thin

sharpie to outline it and then I'm just

going to cut on the inside of the

outline and then it should work

okay so I've cut my filter now it's time

to actually fit it into my pair of

glasses I think that works so far feel

like a hipster not having one of my

lenses there but now I just need to fit

one more of them and I think we'll be

good all right so my glasses are set up

and ready to go let's see if they

actually work

there we go all right so the glasses do

work sorry that the inverter is worked

so you can't really see it all that well

but something I'm going to do is

actually pass these to Brandon and then

hold those over the lens I'm going to do

this live and then I'm going to change

the source and hopefully you guys will

be able to see it better with that over

the lens give me a moment I'm going to

have no idea when this works because I'm

not actually gonna be able to see it

that good okay there we go so the

project worked the monitor didn't but

the inverter dying had nothing to do

with what we did for the project so poor

old like 10-year old flat Ron is is

gonna have to be retired and recycled

after this but oh well I would still

recommend getting an old monitor

I just wouldn't necessarily recommend

getting a very old monitor or one that

you don't trust I bought this one off

Craigslist's for 30 bucks or something

and I only tested it for about two

minutes two weeks ago and now fast

forward two weeks the inverters dead

things are bad another little bit that I

have to say is while being able to

remove the polarizing filter that was on

the monitor and using it again is cool

you also need to remove the anti glare

filter off of here and while it's

possible by soaking it in hot water and

then trying to peel it off like a

sticker and stuff it's really annoying

and the polarizing filters from Amazon

are super cheap and work really well one

thing to note on here is that they also

have a film on it a sticker like

substance which is just supposed to

protect them but it's super easy to take

off so not nearly the same problem that

we have with the anti glare filter

another thing is the goof off or goobie

gun or whatever the heck paint thinner

you end up using to remove your glue let

it sit on there for a while dry it off

let it sit again dry it off let it sit

again do that a few times so that you

don't have to scrape the glue off it

should come off much more evenly and

you'll have a better time I probably

should have done that but honestly it

wasn't that hard

it was scat

she it feels very weird bringing a knife

to a monitor screen it doesn't feel

natural but yeah if you guys do it

please post it on the forum I'd like to

see your projects Mack welding gear

ranging from underwear to undershirts

t-shirts socks sweats and they're really

easy to order and honestly they're

really easy to wear too I mean they're

boxers are literally cradling my man

parts as we speak and I do a great job

of it something that's pretty great is

that their products are naturally

antimicrobial but especially the pima

cotton with silver xt2 ones so I swear

to my girlfriend if you're watching this

these were cleaned before I put them on

but you in the audience should run an

experiment where you get the silver ones

and see how long you can wear them until

they you know like actually smell for

science anyways by the way if you hit up
