frickin lasers whether they're coming out of a stormtroopers blaster or they're mounted on the head of a shark they're undeniably badass and the go-to weapon for evil villains everywhere and now us in our quest to dominate YouTube's tech vertical we will be harnessing the power of the laser so that we can wow guys really that's what we're using it for just like you'll be using Corsairs new HS 50 if you need a wired three-and-a-half millimeter headset it features metal structural components and 50 millimeter neodymium drivers check it out at the link below you know you know what I am I'm gonna wear them for over a year now alex has been trying to figure out how to make a laser cutter that's both powerful and cheap and that's where the good people at smart DIY come in they had the smart idea to make a DIY laser cutter kit giving you the capabilities of a prefab at a lower price by having you assemble it yourself so it's like IKEA I guess and that's what we'll be doing today but first why do we want a laser cutter and what exactly is a laser cutter okay no I'm not gonna wear them the main things that people use them for are to accurately cut plastic or wood in two dimensions or to engrave basically any material and while we already have a 3d printer that can fabricate plastic parts in three dimensions because these parts get printed in layers they can only be their strongest in one direction at this time easily pulling apart in the other further contributing to their weakness is the time and cost associated with printing solid objects using fused deposition modeling so it's much cheaper and faster to make hollow stuff with a laser cutter though you can cut pieces of acrylic without giving up any of the strength of the original material this means you can build load-bearing things like drone components or computer cases using them so enough foreplay then let's meet the smart DIY fabulous co 2 a 40 watt laser cutter kit hailing from Japan we were initially worried this video wouldn't be that interesting then we opened up the packaging and holy Frank look at that laser oh it also computer water cooling parts damn okay this should be fun the frame is made of aluminum extrusion that gets held in place using right angle brackets the instructions aren't perfect and you do have to pay really close attention to the text in pictures but if you follow them very carefully there's no reason to screw anything up now it's time for power there's actually one power supply already in here so that gives us one AC to DC power supply for the electronics then a switching power supply for the laser the next piece is the rail with the stepper motors once the tension is adjusted these tracks should allow our cutter to robot its way around the bed and then these big cable holder tank track chummy's that I'm sure have a real name will keep it from snapping its wires cables go in the motor side then out on the bottom and over to the controller this can communicate to the outside once we have the i/o panel attached which has USB AC power and also this weird fitting thing that I'm not totally sure what it does yet now it's time for water cooling the initial plan was to RGB it up and use our only chance but unfortunately the fan controller uses proprietary wiring and we would need to do a fair bit of careful soldering to get power to our RGB controller so we decided to leave it stock although a hard line tubing upgrade is definitely still on the table down the line when it came time to mount the laser we realized that we didn't have a large enough allen key for these bolts so thank goodness for vice grips Ben we carefully put the laser on making sure not to tighten it down too hard or we could risk breaking it with the laser in wiring it up was pretty much a matter of following the diagram until everything but the pump is connected we'll plug that in once the reservoir is filled the only part of this build that didn't feel all that premium was the dampers for the top cover these long bolts are kind of jank but they do the trick and then with the acrylic installed on top it looks pretty good anyway okay but hold on a minute here if the laser is locked in place in the back how does it cut things ah well it actually gets bounced around to the desired location using front surface mirrors the first one goes back here on this piece of aluminum extrusion and then this is where this project started taking a bit longer than expected it would appear that a big part of the reason that laser cutters cost so much is because of how freakin long it takes to get them properly calibrated so the process is basically like this after putting on the protective not to mention very cool glasses that you need whenever the laser back is open you take the mirror and put a piece of masking tape over it then briefly radiate the laser which creates a burn mark on the tape to show where it's hitting you adjust until it hits in the center and then you're good to go no actually it's not quite that simple either since the laser beam needs to hit the center of all of the mirrors in all of their possible locations around the work area it actually was about a day of fine-tuning before it was finally ready to go the last steps then were filling the loop putting on the final panels installing the software the process for which is conveniently entirely in Japanese and booting it up and it works and it's in English actually so for our first test will engrave a dead meme on a dead pcs side panel with okay so some small issues at first but we'll just turn vsync on here and hey the second half of the etching went without a hitch so guys as of filming this right now we just got this bad boy running and we definitely want to do a follow-up video so let us know what you want to see us do and we'll add it to the list of super cool projects that we have planned for the fabula co2 and on the subject of things that are super cool Tunnel bear if you've been looking for an easy-to-use VPN app then tunnel bear is the first and last place to look it's super easy to use and they've got apps available for iOS Android they've got a Chrome extension they've got it for PC they've got it for Mac and it's got lots of great features as well one of them is what's called switch so before you connect to a network your device actually starts to send information about itself and what it wants to do and a kill switch stops this from happening because during that time before you connect to a normal VPN all that traffic is unencrypted so in the few seconds it takes to connect you've probably already broadcast your IP maybe a few DNS requests or a search query vigilant Bear stops all this from happening by blocking all outbound and inbound traffic so nothing leaks out before you connect and if your connection goes down for some reason vigilant bear will kick back in and stop until the connection comes back so for a free trial of tunnel bear go to tunnel bear comm /l tt will have that linked below thanks for watching guys if this video suck do you know what to do but if it's awesome put on some glasses like this get subscribed hit that like button or check out the link to where to buy the stuff we featured in the video description also linked in the description is our merch store which has cool shirts like this one and our community forum which you should totally join
