1 00:00:00,080 --> 00:00:06,040 have you ever been in a situation where you might have broken a computer or 2 00:00:03,800 --> 00:00:09,440 maybe the computer broke itself and you don't have a way to access it 3 00:00:07,640 --> 00:00:13,440 fortunately for us most of the systems we work on here at LTT LMG ShortCircuit 4 00:00:12,000 --> 00:00:16,920 whatever you want to call it have something called ipmi or Remote 5 00:00:15,280 --> 00:00:21,039 Management it's like a mini computer attached to the main computer so if it 6 00:00:18,800 --> 00:00:25,599 freezes or something you can turn the power off and on again but if you don't 7 00:00:23,439 --> 00:00:29,160 have Hardware like that you don't really have a way to do that without physically 8 00:00:27,279 --> 00:00:33,520 going and pressing the power button at least until now or I mean realistically 9 00:00:32,399 --> 00:00:40,000 Solutions like this have been on the market for a while but this one the 10 00:00:36,399 --> 00:00:42,440 scied Nano KVM light and I guess this 11 00:00:40,000 --> 00:00:46,840 one's just the Nano KVM can do it for very 12 00:00:43,600 --> 00:00:49,440 cheap wow oh it's so cute this is like 13 00:00:46,840 --> 00:00:53,559 $30 or something like this this little Gadget right here you connect HDMI to 14 00:00:51,280 --> 00:00:57,480 your computer USB to your computer and some of these pins to like the power and 15 00:00:55,359 --> 00:01:02,680 reset switches and now you have full remote visibility and physical power 16 00:01:00,600 --> 00:01:05,840 switch control over any computer you want you also through that USB have 17 00:01:04,479 --> 00:01:11,119 keyboard and mouse now you might have heard of similar projects like the P KVM 18 00:01:08,600 --> 00:01:15,040 which is an awesome way to do that uh open source kind of community project 19 00:01:13,439 --> 00:01:19,759 but it's still pretty expensive even if you build the thing yourself you're talking an order of a couple hundred 20 00:01:18,119 --> 00:01:25,600 cheaper than an Enterprise solution which does exist but if you're trying to 21 00:01:22,360 --> 00:01:27,479 do this at your house $30 seems a lot 22 00:01:25,600 --> 00:01:31,680 more compelling let's get the the big boy unboxed here o look at that we got 23 00:01:29,520 --> 00:01:36,479 the little unit right there we got the little board this is like for the front 24 00:01:34,000 --> 00:01:40,479 panel header so the power button just a little bit cleaner way to do that rather 25 00:01:38,439 --> 00:01:45,240 than having to like run jumper cables off of this one oh look jumper cables 26 00:01:42,320 --> 00:01:48,719 that's helpful USB cable a two a to c cables okay naturally the fully fledged 27 00:01:47,320 --> 00:01:53,280 version is more expensive you're looking around $60 but it does have some little 28 00:01:51,240 --> 00:01:56,799 cute goodies uh we can't see it yet but there's an OLED screen under here that 29 00:01:55,040 --> 00:02:00,360 prints out the IP address of the device which can be helpful if you don't know 30 00:01:58,360 --> 00:02:05,240 how to get that it's got buttons that are accessible like power and reset it 31 00:02:02,880 --> 00:02:09,319 also comes with the little daughter board that you can plug right into the 32 00:02:06,759 --> 00:02:13,080 headers of a computer that way you can do the power situation a little nicer 33 00:02:11,200 --> 00:02:16,480 and it also comes with the jumper cables to plug that in ports wise they're 34 00:02:14,920 --> 00:02:21,200 pretty similar but you can see the fully fledged one has an extra USB port and 35 00:02:18,840 --> 00:02:24,599 that's for auxiliary power so the light is meant to run off of the computer it's 36 00:02:22,840 --> 00:02:28,440 controlling so it gets power and also supplies the mouse and keyboard signals 37 00:02:26,680 --> 00:02:33,000 to the computer through this one USBC Port but if that computer stops 38 00:02:30,599 --> 00:02:36,840 supplying power for instance then this stops getting power that's why there's 39 00:02:34,720 --> 00:02:40,400 an extra power cable on this one an example I could think of is like during 40 00:02:38,160 --> 00:02:44,239 a BIOS update let's say the computer by default doesn't provide power from the 41 00:02:42,200 --> 00:02:48,680 USB ports when it's off and you set the BIOS to change that and then you updated 42 00:02:46,280 --> 00:02:52,680 the BIOS well now you can't fix it with this on this one you'll have external 43 00:02:50,040 --> 00:02:57,080 power and you totally could I suspect that the pins on the light one there's 44 00:02:54,879 --> 00:02:59,959 probably a PIN to Supply 5vt Power separately um so you could probably 45 00:02:58,760 --> 00:03:04,599 still set this one up to have have external power it just requires a little 46 00:03:02,000 --> 00:03:08,840 bit more work oh this one has two extra type-c ports what is what you see this 47 00:03:08,000 --> 00:03:17,680 one two three oh I'm so silly oh that's so 48 00:03:14,920 --> 00:03:23,040 cool okay actually I'm wrong you don't connect the little control board with 49 00:03:20,560 --> 00:03:27,599 the jumpers you connect the control board with a USB cable that's what the 50 00:03:26,280 --> 00:03:30,680 third port is for and that's why it comes with two cables plugging into 51 00:03:29,519 --> 00:03:35,519 there you take this and you plug it into your motherboard chunk that's much cleaner I 52 00:03:34,280 --> 00:03:39,920 like that actually just reading this diagram on the side these connections 53 00:03:37,439 --> 00:03:43,560 here are for cereal and I have heard some Rumblings from Wendell that he's 54 00:03:42,159 --> 00:03:49,720 setting it up so you could plug one of his kvms into this thing and instead of 55 00:03:45,560 --> 00:03:52,120 it being a single computer KVM bam now 56 00:03:49,720 --> 00:03:56,439 it's a four Compu KVM I guess let's power it on 57 00:03:53,640 --> 00:04:00,519 boom Oh it has lights now you might notice there's a Micro SD card in here 58 00:03:58,159 --> 00:04:04,239 already the light version does come with an SD card they just provided one when 59 00:04:02,560 --> 00:04:07,959 they sent these to us while we wait for this to turn on and there is some 60 00:04:05,560 --> 00:04:12,040 undesirables regarding the Nano KVM we should probably mention specifically 61 00:04:09,879 --> 00:04:14,920 that the firmware is not yet open source and a hacker man's on the internet did 62 00:04:13,439 --> 00:04:18,880 reverse engineer some of it and found some things that are not that great like 63 00:04:16,680 --> 00:04:25,479 hardcoded secret keys for things which is not good and randomly a cat picture 64 00:04:22,720 --> 00:04:31,199 they are a Chinese company so once they open source the firmware 65 00:04:27,880 --> 00:04:34,080 and hopefully at some point Port Pi KVM 66 00:04:31,199 --> 00:04:38,039 software which is really great software to it then that stuff should be resolved 67 00:04:36,280 --> 00:04:42,639 and in theory you could roll your own software but for now you kind of have to 68 00:04:40,400 --> 00:04:45,840 deal with that being the case it is still like a beta and they have 69 00:04:43,880 --> 00:04:51,320 committed to like fixing the things that were mentioned by that dude but for now 70 00:04:48,400 --> 00:04:54,600 buy or beware probably run it on a VLAN if you're going to use these things 71 00:04:52,759 --> 00:04:58,560 thanks pulseway for sponsoring today's video they've simplified monitoring your 72 00:04:56,800 --> 00:05:02,720 network and systems by giving you the freedom to do it on the go just set up 73 00:05:00,400 --> 00:05:06,160 an automation or turn on notifications and you'll never have to worry about 74 00:05:04,160 --> 00:05:10,000 keeping someone on site again plus it works with practically any operating 75 00:05:08,120 --> 00:05:14,800 system you can think of start a free trial today and save 40% on all pulseway 76 00:05:12,880 --> 00:05:19,520 plans using our Link in the description this is um not looking great it's barely 77 00:05:17,919 --> 00:05:24,280 doing anything I have a sneaking suspicion it's like very out of date 78 00:05:21,400 --> 00:05:29,319 firmware or something see loaded the JavaScript 79 00:05:26,080 --> 00:05:31,520 hey okay it's working now I suspect that 80 00:05:29,319 --> 00:05:36,160 it was n getting enough power so I plugged in the extra power cable which 81 00:05:33,520 --> 00:05:42,319 was charging my laptop before and now it's working 82 00:05:38,479 --> 00:05:44,560 HDMI hey wow it's working look at that 83 00:05:42,319 --> 00:05:47,440 kind of I can't interact with it let me see if there's a firmware update before 84 00:05:45,880 --> 00:05:50,639 we go any further check for update there's a minor one let's let's run that 85 00:05:49,280 --> 00:05:54,000 and then we'll try it it's one of those updates that doesn't have a progress bar 86 00:05:52,520 --> 00:05:58,080 it just says update started in a spinning Circle for whatever reason the 87 00:05:55,560 --> 00:06:01,759 update seems to just get stuck it shows pending in the developer console for 88 00:05:59,919 --> 00:06:06,479 Chrome forever so I'm going to open this up and Flash the new image on the SD 89 00:06:03,919 --> 00:06:09,360 card that's in here and then we'll try it again and see if it works I mean I 90 00:06:08,000 --> 00:06:13,560 guess this is a good opportunity to see what's inside this one it's a bit 91 00:06:11,240 --> 00:06:17,319 strange that they didn't just leave a a hole in the mold so you could get at the 92 00:06:15,360 --> 00:06:22,319 SD card if you wanted like if it died and you wanted to replace it or something like that oh God yeah see like 93 00:06:20,360 --> 00:06:27,840 that's not that easy to get to it hits the this so even having it open this 94 00:06:24,680 --> 00:06:29,240 much I I still can't get at it wow cute 95 00:06:27,840 --> 00:06:34,080 oh look at that it's got a little more going on on in here the bottom and this 96 00:06:31,599 --> 00:06:39,199 is like you can see like how much is the same it's just got like a little hat on 97 00:06:36,720 --> 00:06:43,800 top with the screen and the extra USB ports I'm not going to lie and say it 98 00:06:40,680 --> 00:06:47,000 isn't kind of Jank that this screen is 99 00:06:43,800 --> 00:06:52,680 just literally vibing in there it gets 100 00:06:47,000 --> 00:06:56,080 held down a bit by the plastic on top 101 00:06:52,680 --> 00:06:57,879 but it's still free roaming well the 102 00:06:56,080 --> 00:07:02,199 screen says it's not working but I just accessed it oh yeah it's loading way 103 00:07:00,400 --> 00:07:05,479 faster now so there's two different versions we're talking about here 104 00:07:03,520 --> 00:07:10,520 there's the firmware image of the device which is what you flash to the SD card 105 00:07:07,919 --> 00:07:14,919 and then there's like the version of the web interface that you're interacting 106 00:07:12,840 --> 00:07:18,360 with I flashed the new image on there which seems to have fixed our internet 107 00:07:16,680 --> 00:07:22,680 problems and then I just updated the application that seems to fix our screen 108 00:07:20,680 --> 00:07:27,440 I think they borked something because every time I updated it says It's On 109 00:07:24,440 --> 00:07:29,800 2.04 Again and that it has an update to 110 00:07:27,440 --> 00:07:34,800 2.07 fast forward a few days and we got a response back from the C cype people I 111 00:07:32,879 --> 00:07:38,879 think that's how you pronounce it doesn't matter the people that make the 112 00:07:36,160 --> 00:07:42,560 Nano KVM which is what this thing is and uh it turns out it was a bug with their 113 00:07:40,520 --> 00:07:46,919 CDN where it was like caching an old version of the firmware so when you 114 00:07:43,919 --> 00:07:49,199 updated it was downloading and updating 115 00:07:46,919 --> 00:07:53,120 to the version it was already on they sent us a little script to update it 116 00:07:51,240 --> 00:07:57,800 properly which seems to have worked and look I have a computer output it's 117 00:07:56,360 --> 00:08:02,159 actually kind of better than I was expecting to be honest I I thought it 118 00:07:59,840 --> 00:08:07,199 was going to be a pretty choppy crappy experience like usable but not great 119 00:08:05,479 --> 00:08:12,720 that's because it's based on a super tiny development single board computer 120 00:08:09,879 --> 00:08:17,319 called the lchi RV Nano which is I mean the light version here it's almost the 121 00:08:14,319 --> 00:08:19,440 entirety of the unit but it's very small 122 00:08:17,319 --> 00:08:24,000 and it uses a risk five architecture so it's reduced instruction set and open 123 00:08:21,960 --> 00:08:30,159 source technically and that's what makes it so cheap but it's also only three 124 00:08:27,680 --> 00:08:36,440 cores I think technically one one major core one minor core and one low power 125 00:08:32,640 --> 00:08:38,279 core and then 256 megab of DDR3 memory 126 00:08:36,440 --> 00:08:41,399 on this little guy tail scale is great because you can remotely connect to it 127 00:08:39,719 --> 00:08:45,480 without port forwarding uh it's basically like a peer-to-peer VPN if 128 00:08:43,000 --> 00:08:48,760 you're not familiar and it is directly integrated I'm not going to set it up 129 00:08:47,080 --> 00:08:52,959 but we can click the login to see what it does the fact that that's integrated 130 00:08:50,600 --> 00:08:56,519 in is super nice oh yeah look at that login. scale click the button and log in 131 00:08:55,080 --> 00:09:01,200 I mean aside from that there's not a whole lot else you can do I could try oh 132 00:08:59,560 --> 00:09:06,600 look at that okay so one of the headers it connects to is a hard drive LED and 133 00:09:03,440 --> 00:09:08,440 if your hard drive LED is blinking uh it 134 00:09:06,600 --> 00:09:12,160 supposedly will display in here and I also could press the power button 135 00:09:10,240 --> 00:09:16,800 although that is not connected right now you can issue wake on land you can open 136 00:09:14,360 --> 00:09:22,320 a terminal you can run scripts oh you know what here let me try to mount an 137 00:09:18,760 --> 00:09:25,120 image let's try and enable virtual USB 138 00:09:22,320 --> 00:09:29,560 again does that oh hey look at that uh virtual USB just like lets you access 139 00:09:27,560 --> 00:09:33,040 the SD card so here's all my ubun two isos in here if I want a boot off of it 140 00:09:31,440 --> 00:09:38,480 I need to reboot it well let's try and reboot this computer and install Ubuntu 141 00:09:36,120 --> 00:09:42,720 on it or at least start the installer oh it's working look at that it does 142 00:09:40,200 --> 00:09:47,360 everything I would want in a KVM I mean realistically I'm not the type to like 143 00:09:44,680 --> 00:09:51,120 wire in leads for my power button even though I do like the implementation of 144 00:09:49,320 --> 00:09:54,040 it just like being a USB cable that makes it a lot less Jank than just 145 00:09:52,560 --> 00:10:00,079 having a bunch of random wires running all over the place it seems to do like 146 00:09:56,640 --> 00:10:02,480 KVM SL you know remote management 147 00:10:00,079 --> 00:10:06,920 control of a computer stuff just fine I mean I'm booting up the Ubuntu desktop 148 00:10:04,720 --> 00:10:11,480 2404 here it's probably going to take a little while cuz it's USB 2 but it is 149 00:10:08,880 --> 00:10:16,839 booting it's a little glitchy the update experience wasn't the best but for $30 I 150 00:10:14,560 --> 00:10:21,000 really can't complain I uh I think if you're looking for something like this 151 00:10:18,279 --> 00:10:24,920 and you're the tinkering type this is probably good enough for you and you'll 152 00:10:22,680 --> 00:10:29,320 probably like to screw around with it uh if you're more Normy and you like your 153 00:10:27,880 --> 00:10:34,120 stuff to just work well I probably probably wouldn't go with this yet check 154 00:10:31,760 --> 00:10:38,880 out a pi KVM those things are really robust uh but way more expensive and 155 00:10:36,800 --> 00:10:43,279 look at that there's theun to is staller beautiful it works if you do buy one 156 00:10:41,040 --> 00:10:48,040 make sure you flash the new firmware and then check their GitHub issues for how 157 00:10:45,600 --> 00:10:52,560 to flash the new software for the dashboard because that was a whole kurk 158 00:10:49,560 --> 00:10:54,279 buffle but overall pretty sick so thanks 159 00:10:52,560 --> 00:10:58,680 for watching if you like this video hit the like button check out maybe the 160 00:10:56,519 --> 00:11:02,560 ubiquity Cloud Gateway Max video that we did recently that was pretty fun
