00:00:00.400 --> 00:00:07.200
freaking lasers whether they're coming out of a stormtrooper's blaster or

00:00:05.440 --> 00:00:12.160
they're mounted on the head of a shark they're undeniably badass and the go-to

00:00:09.679 --> 00:00:15.280
weapon for evil villains everywhere and

00:00:13.440 --> 00:00:20.800
now us in our quest to dominate youtube's

00:00:18.400 --> 00:00:26.160
tech vertical we will be harnessing the power of the laser so that we can

00:00:24.000 --> 00:00:31.840
wow guys really that's what we're using it for

00:00:29.279 --> 00:00:36.640
just like you'll be using Corsair's new hs50 if you need a wired three and a

00:00:34.559 --> 00:00:41.040
half millimeter headset it features metal structural components and 50

00:00:38.640 --> 00:00:49.029
millimeter neodymium drivers check it out at the link below

00:00:51.920 --> 00:00:57.199
you know you know what i i am i'm gonna wear them

00:00:55.039 --> 00:01:03.920
for over a year now alex has been trying to figure out how to make a laser cutter

00:00:59.840 --> 00:01:05.519
that's both powerful and cheap

00:01:03.920 --> 00:01:12.400
and that's where the good people at smart diy come in they had the smart

00:01:08.960 --> 00:01:15.280
idea to make a diy laser cutter kit

00:01:12.400 --> 00:01:19.520
giving you the capabilities of a prefab at a lower price by having you assemble

00:01:17.600 --> 00:01:23.520
it yourself so it's like ikea i guess

00:01:21.200 --> 00:01:26.799
and that's what we'll be doing today but first

00:01:24.560 --> 00:01:30.799
why do we want a laser cutter and what exactly is a laser cutter okay no i'm

00:01:29.680 --> 00:01:37.119
not gonna wear them the main things that people use them for

00:01:33.200 --> 00:01:40.479
are to accurately cut plastic or wood in

00:01:37.119 --> 00:01:41.759
two dimensions or to engrave basically

00:01:40.479 --> 00:01:46.479
any material and while we already have a 3d printer

00:01:44.240 --> 00:01:50.880
that can fabricate plastic parts in three dimensions

00:01:48.159 --> 00:01:56.880
because these parts get printed in layers they can only be their strongest

00:01:53.840 --> 00:01:59.360
in one direction at this time

00:01:56.880 --> 00:02:04.479
easily pulling apart in the other further contributing to their weakness

00:02:01.520 --> 00:02:09.599
is the time and cost associated with printing solid objects using fused

00:02:07.040 --> 00:02:15.040
deposition modeling so it's much cheaper and faster to make hollow stuff

00:02:12.480 --> 00:02:19.760
with a laser cutter though you can cut pieces of acrylic without giving up any

00:02:17.440 --> 00:02:24.560
of the strength of the original material this means you can build load-bearing

00:02:21.680 --> 00:02:28.560
things like drone components or computer cases using them

00:02:26.160 --> 00:02:35.280
so enough foreplay then let's meet the smart diy fabool c02 a 40 watt laser

00:02:32.879 --> 00:02:39.120
cutter kit hailing from japan we were initially worried this video

00:02:37.360 --> 00:02:44.480
wouldn't be that interesting then we opened up the packaging and holy

00:02:41.519 --> 00:02:50.400
frank look at that laser oh and also computer water cooling parts

00:02:46.959 --> 00:02:52.400
damn okay this should be fun the frame

00:02:50.400 --> 00:02:57.280
is made of aluminum extrusion that gets held in place using right angle brackets

00:02:55.200 --> 00:03:01.599
the instructions aren't perfect and you do have to pay really close attention to

00:02:59.519 --> 00:03:06.000
the text and pictures but if you follow them very carefully there's no reason to

00:03:03.680 --> 00:03:12.159
screw anything up now it's time for power there's actually one power supply

00:03:08.800 --> 00:03:14.720
already in here so that gives us one ac

00:03:12.159 --> 00:03:19.440
to dc power supply for the electronics then a switching power supply for the

00:03:16.959 --> 00:03:24.480
laser the next piece is the rail with the stepper motors once the tension is

00:03:21.680 --> 00:03:29.840
adjusted these tracks should allow our cutter to robot its way around the bed

00:03:27.120 --> 00:03:34.480
and then these big cable holder tank track chummies that i'm sure have a real

00:03:32.239 --> 00:03:39.519
name will keep it from snapping its wires cables go in the motor side then

00:03:37.599 --> 00:03:42.640
out on the bottom and over to the controller

00:03:40.640 --> 00:03:48.159
this can communicate to the outside once we have the i o panel attached which has

00:03:44.959 --> 00:03:50.239
usb ac power and also this weird fitting

00:03:48.159 --> 00:03:54.319
thing that i'm not totally sure what it does yet

00:03:51.519 --> 00:03:59.680
now it's time for water cooling the initial plan was to RGB it up and use

00:03:56.799 --> 00:04:03.920
our own lit af fans but unfortunately the fan controller uses proprietary

00:04:01.760 --> 00:04:08.560
wiring and we would need to do a fair bit of careful soldering to get power to

00:04:06.159 --> 00:04:13.439
our RGB controller so we decided to leave it stock although

00:04:10.879 --> 00:04:17.440
a hardline tubing upgrade is definitely still on the table down the line

00:04:15.519 --> 00:04:22.560
when it came time to mount the laser we realized that we didn't have a large

00:04:19.680 --> 00:04:27.280
enough allen key for these bolts so thank goodness for vice grips

00:04:25.280 --> 00:04:32.080
then we carefully put the laser on making sure not to tighten it down too

00:04:29.440 --> 00:04:35.919
hard or we could risk breaking it with the laser in wiring it up was pretty

00:04:34.000 --> 00:04:39.840
much a matter of following the diagram until everything but the pump is

00:04:37.440 --> 00:04:43.759
connected we'll plug that in once the reservoir is filled the only part of

00:04:42.160 --> 00:04:49.120
this build that didn't feel all that premium was the dampers for the top

00:04:45.919 --> 00:04:51.759
cover these long bolts are kind of jank

00:04:49.120 --> 00:04:55.280
but they do the trick and then with the acrylic installed on top it looks pretty

00:04:54.000 --> 00:05:01.440
good anyway okay but hold on a minute here if the

00:04:58.080 --> 00:05:03.840
laser is locked in place in the back

00:05:01.440 --> 00:05:07.440
how does it cut things ah

00:05:04.720 --> 00:05:11.600
well it actually gets bounced around to the desired location using front surface

00:05:10.479 --> 00:05:16.000
mirrors the first one goes back here on this

00:05:13.840 --> 00:05:20.800
piece of aluminum extrusion and then this is where this project

00:05:19.199 --> 00:05:28.080
started taking a bit longer than expected it would appear that a big part of the

00:05:24.400 --> 00:05:30.560
reason that laser cutters cost so much

00:05:28.080 --> 00:05:36.080
is because of how freaking long it takes to get them properly calibrated

00:05:33.199 --> 00:05:41.600
so the process is basically like this after putting on the protective not to

00:05:38.400 --> 00:05:44.080
mention very cool glasses that you need

00:05:41.600 --> 00:05:48.960
whenever the laser back is open you take the mirror and put a piece of masking

00:05:46.080 --> 00:05:53.039
tape over it then briefly radiate the laser which creates a burn mark on the

00:05:51.199 --> 00:05:57.759
tape to show where it's hitting you adjust until it hits in the center

00:05:55.600 --> 00:06:01.039
and then you're good to go no actually it's not quite that simple

00:06:00.000 --> 00:06:09.199
either since the laser beam needs to hit the center of all of the mirrors in all of

00:06:06.560 --> 00:06:12.800
their possible locations around the work area

00:06:10.080 --> 00:06:18.880
it actually was about a day of fine tuning before it was finally ready to go

00:06:16.639 --> 00:06:23.919
the last steps then were filling the loop putting on the final panels

00:06:21.440 --> 00:06:27.280
installing the software the process for which is conveniently entirely in

00:06:25.759 --> 00:06:30.800
japanese and booting it up

00:06:29.360 --> 00:06:35.520
and it works and it's in english actually

00:06:32.960 --> 00:06:41.120
so for our first test we'll engrave a dead meme on a dead pc side panel with

00:06:39.919 --> 00:06:46.880
okay so some small issues at first but we'll

00:06:44.160 --> 00:06:50.800
just turn vsync on here and uh hey the second half of the etching went

00:06:48.560 --> 00:06:55.840
without a hitch so guys as of filming this right now we

00:06:53.600 --> 00:06:59.840
just got this bad boy running and we definitely want to do a follow-up video

00:06:57.680 --> 00:07:02.960
so let us know what you want to see us do

00:07:00.720 --> 00:07:07.919
and uh we'll add it to the list of super cool projects that we have planned for

00:07:05.120 --> 00:07:11.520
the fabul co2 and on the subject of things that are

00:07:09.280 --> 00:07:18.000
super cool tunnelbear if you've been looking for an easy to use vpn app then

00:07:15.199 --> 00:07:22.880
tunnelbear is the first and last place to look it's super easy to use and

00:07:20.240 --> 00:07:26.880
they've got apps available for iOS Android they've got a chrome extension

00:07:24.960 --> 00:07:30.720
they've got it for pc they've got it for mac and it's got lots of great features

00:07:28.479 --> 00:07:35.360
as well one of them is what's called a kill switch so before you connect to a

00:07:33.360 --> 00:07:38.560
network your device actually starts to send information about itself and what

00:07:37.039 --> 00:07:43.360
it wants to do and a kill switch

00:07:40.319 --> 00:07:45.440
stops this from happening because during

00:07:43.360 --> 00:07:50.240
that time before you connect to a normal vpn all that traffic is unencrypted so

00:07:48.400 --> 00:07:54.319
in the few seconds it takes to connect you've probably already broadcast your

00:07:52.080 --> 00:07:58.639
ip maybe a few dns requests or a search query vigilant bear stops all this from

00:07:56.560 --> 00:08:02.240
happening by blocking all outbound and inbound traffic so nothing leaks out

00:08:00.560 --> 00:08:06.960
before you connect and if your connection goes down for some reason

00:08:04.000 --> 00:08:10.840
vigilant bear will kick back in and stop until the connection comes back so for a

00:08:09.199 --> 00:08:14.639
free trial of tunnelbear go to tunnelbear.com LTT we'll have that
