 So here is my new K40 Laser. Bought it from Amazon, about 400 bucks, and this is not an unboxing video, but I just wanted to show everybody what it comes like, how good the packaging is, so you can expect if things are broken, and then I was going to go through all the common things that people have complained about safety-wise and see if they're applicable to this and then fix them and then, I don't know, I'll just show you how I set this thing up for myself, where I feel comfortable using it. So I was surprised to see two layers of protection on this thing. It's got foam inside, then a box, and more foam. So that was good to see that hopefully that would protect this thing against jostling and getting it too broken before anybody's able to use it. But there you see there's the laser and it's three or four controls, and I'll start taking this out and see how it looks. Alright, so the machine was actually pretty easy to get out of the box. I was able to do it myself. Not a massive weight. Lovingly, they provide this ducting for the fan that they smashed in here, so that's great. I like it. And then here's the chintzy little fan, which I'm gonna have to open that area up right there and check to see what the wiring looks like, because apparently that is also one of the atrocious areas where they barely connect the wires and such. And yeah, this cord doesn't look up to snuff, but that's China for you. Other than that, so far it looks okay. I don't know how the alignment is, what the grounding is gonna be like back there, but I'll figure it out. They also had the aquarium pump in here to pump some water, and one thing I noticed, and I'll turn this around and show, is there's already water in the tube, so I guess they need to make sure these things don't get cold and freeze, otherwise you can end up with a cracked tube. So I'll keep chipping away at this and get back. Alright, here's the laser tube as they shipped it. It seems to be okay. I don't think anything is broken. And while the tubes, these tubes down here, they have water in them. It looks like whatever testing they did, they drained the laser tube correctly of any water. So that was nice to see. I don't know. What else I need to show in here? They had a little piece of, I'll figure you can see over there at the end. They had a little piece of padding that you might want to remove, but other than that, there's nothing in the way of the laser itself that would catch fire if you were to start this thing up. The other thing, this cover that sits on here, it's got these little things because apparently they understand if they had something to hold this open that would be useful. So that would be too much. So they just put these little spring-loaded, I don't know what you call them, posts to keep this on here. Normally, and then when you want to take this off or say doing anything with a laser, you can take it off. So that was at least nice of them to do that. But for a price point, I guess I can't complain too much. And really, you shouldn't be back here too often unless you're changing after two or aligning your mirrors, which I guess isn't going to happen too frequently. But anyway, everything looks okay back here. I was concerned I might get a broken tube. It doesn't appear that way. So I'll keep that closed and then I'll go look over here down this red grounding plug, see how the grounding is functioning. And I'll look down here. And it looks like it has some European outlets. So I guess I won't be using those. But from what I read online, you shouldn't be using those anyways. They're not properly grounded. Anyway, so if you plug something into them, you're not going to get any grounding. So I'll keep going. I'll take this thing off, see how the connection to the chassis or the case is, and give that some sanding love to get some electrical connection with the chassis. So if anything, short circuits or electrifies the case, the grounding works properly. Okay, I think it was worse than I expected. I wasn't expecting much, but you can't see it and I'll bring you down there, but you can see this. We'll see if that focuses. This is the outside. So the grounding plug, a little red piece on the outside. And here's a piece of plastic and another piece of plastic. And then the fasteners holding them together. So the case would be in between here, insulated between these two pieces of plastic. And I'm not sure how grounding the case would work in that case. Maybe I'm dumb, but this seems to do the exact opposite of what you would want to do if you want to ground the case from any potential major electric shocks. So yeah, I'm sure this keeps the paint looking nice, but it doesn't do anything for safety. And I'll take the camera off the tripod here and bring you down in the innards. I don't know, can you see? Can you see the flashlight flashing? But there's the hole for the grounding and there is no, and it's all paint. So the case is not grounded at all. So this would be pretty, pretty scary to use right out of the box. And that's why I wanted to go through and do this kind of stuff, because it's scary. Again, apparently they don't have much in the way of grounding as a standard in China. That's why they have the grounding plug. Whereas in the U.S. we have the three pronged outlets. So yeah, if you're going to get one of these, make sure to fix that, because that seemed pretty dangerous to me and I'm not an electrical expert. But I can, I can read and that, and that that's definitely something you want to, you want to fix. So here's the back of the machine. And I just started on this, but I figured I'd show you what I want to do. But first I'm just going to use this razor knife to clean out that hole. And I don't know if I can get any closer without it. And here we'll focus, but then just scratch on the paint here so that my sandpaper can get a bite. So I'm just going to do that until I get down to bare metal. And I'll do that on the inside as well. And then we'll have some actual grounding of the case. So any electrical arcs, arcing to the case, will actually go to ground through this top plug here. So I'll get on that and then I'll come back to you. I have to say the pile of foam that comes with this thing, you see it over there. It's very good as a working material to put your knees on. I'm on a low table so this is actually helpful to me. Maybe some people who have full-size tables, the elite wouldn't need this, but us plebeians, we need it. All right, so there's the sanding job done on the outside at least. So that will make me feel a little safer. It's fascinating how this is a commercial product. You can buy it on Amazon. And yet it ships and it could kill you. If you're not careful. I mean obviously it's got a laser. That could kill you too. Blind you, whatever. But this is like built-in design or lack of design. Just oversight. We're not caring. Anyways, I'm going to do the same thing to the inside. Then I'll put back on the grounding plug with the wires that were grounded to it. Sands the insulating portions that they put on there. And that'll be a little better. So I found that you could take this cover off just like you could the back one. So that was nice. So it's easier access for sanding inside there. There you can see. It's sanded. Metal's in contact with the case. Now I feel a little better. It was odd when I took these off, when I took those nuts off. It was like the factory workers knew that you're going to have to take them off and fix this. So it was barely hand tightened. Required very little effort to get the grounding components off. So I'm going to reattach those. Then I'll be looking inside this fan motor, which I don't expect will be very impressive. From what I've read, the best option is to replace your chintzy bent hose with some dryer vent hose and have the ability to exhaust your air but have the actual fan at the outside or the end of your vent run so that you're always, you've got negative pressure and you're always sucking air instead of pushing air. And I'll be venting out this door. I'll just cut a little hole in there. Put a dryer vent kind of thing in there. Let's crack into this. Let's see what awaits us. Oh, look at that. Well, yeah. There's no soldering or anything. I don't know if you can see that. I can illuminate us here. Yeah, let's just wrap some wires around each other and put if he's plus tubing and hope for the best. So that's pretty enlightening. Anyway, I guess I'll have to fix that. Just some soldering and heat-ring tubing. But yeah, this doesn't inspire too much confidence. I'll probably just do what I said and just get an inline duct fan and have that have that hook up directly to the door that I'm going to vent out of. Because this doesn't look like it would be sufficient to do much of anything. Anyway, I'll at least take care of this and see what it'll do. All right, after some soldering, we got rid of these chinsy little pieces of tubing and very loosely held together wires and heat shrunk them. The way these ones were just due to the ends, but they will hold together much better now and I don't have to worry about any electrical connections, arcing and sparking, because they aren't connected properly. And so I'll just put that back on and I thought to myself, now that I've got this together, should I try it out? Well, what's the point if I don't know how powerful it is? But guess what I have? An anemometer. Because why not have an anemometer? So I'm going to plug this in and then I'll uh, see what kind of power it has. Don't blow up, we'll get this cord. Only from China can you get these cords with no holes on the plugs. I don't know why. A finicky. This outlet, this power strip, it doesn't have problems. Really it doesn't. There we go. So now get out my anemometer. Change my 74 feet per minute. It seems to move a decent amount of air. Feels nice. There's that fan, use it at your own risk I suppose, after you fix the wiring in it. Maybe use it for some other project.
