1
00:00:00,260 --> 00:00:08,099
I got covered I'm better now mostly but

2
00:00:05,640 --> 00:00:12,780
I was stranded in a hotel for two weeks with absolutely nothing to do but watch

3
00:00:10,019 --> 00:00:18,660
YouTube and stick cotton swabs up my nose at least that's what I would say if

4
00:00:16,680 --> 00:00:23,279
not for this this unassuming little box let me

5
00:00:21,180 --> 00:00:28,740
connect back to my test bench at the office and do actual work from the

6
00:00:25,920 --> 00:00:33,899
comfort of my hotel room I can do crazy things like use my smartphone over 5G to

7
00:00:32,099 --> 00:00:38,280
power on this completely ordinary computer without wake on land it's not

8
00:00:36,120 --> 00:00:42,960
even plugged into the network and it's not just power I can also see the screen

9
00:00:40,620 --> 00:00:47,460
interact not only with Windows but even the BIOS as if I were sitting right in

10
00:00:45,780 --> 00:00:53,640
front of the computer right I could even overclock this PC

11
00:00:50,960 --> 00:00:58,020
completely remotely how does it work

12
00:00:55,379 --> 00:01:02,820
I'm glad you asked and I'm glad you asked about our sponsor G skill their

13
00:01:00,120 --> 00:01:07,860
Trident Z5 Neo ddr5 memory is built for AMD ryzen 7000 series processors and one

15
00:01:17,520 --> 00:01:23,220
meet Pi KVM V3

16
00:01:21,000 --> 00:01:27,000
is it open source hat for Raspberry Pi that launched as a Kickstarter and

17
00:01:24,659 --> 00:01:31,920
started shipping about a year ago let's try it on a laptop plugged in via

18
00:01:28,979 --> 00:01:37,079
Ethernet the delay actually isn't too bad like the cursor is skipping around a

19
00:01:34,680 --> 00:01:41,040
little bit but as good as it kind of is with their claim of 100 milliseconds at

20
00:01:39,240 --> 00:01:45,240
best like for a device like this that's amazing that's before you consider your

21
00:01:44,040 --> 00:01:50,399
network latency you're not going to want a game on it at all plus 1080p 60 is the

22
00:01:48,060 --> 00:01:53,280
absolute most you're going to get now if you're tied on bandwidth you can

23
00:01:51,600 --> 00:01:57,720
actually limit the frame rate by yourself in the system menu here and set

24
00:01:55,619 --> 00:02:02,460
the bit rate you'd like to use for h.264 encoding which I can switch to right

25
00:01:59,939 --> 00:02:06,420
there of course none of this requires anything special from the host PC here

26
00:02:04,680 --> 00:02:11,340
because it's completely out of the loop all we have is HDMI and USB plugged into

27
00:02:09,780 --> 00:02:15,720
the motherboard here for control and that's it with an inexpensive HDMI

28
00:02:13,920 --> 00:02:20,640
splitter you'd never know it was there oh and that reminds me the USB

29
00:02:17,520 --> 00:02:22,800
connection here that's for more than

30
00:02:20,640 --> 00:02:27,239
just the keyboard and mouse you can use it as a network bridge you could use it

31
00:02:24,360 --> 00:02:33,480
for a Serial port and even this one is really cool as a USB drive for

32
00:02:31,200 --> 00:02:37,020
connecting up disk images I could install an entire operating system

33
00:02:35,220 --> 00:02:42,300
without ever needing to physically touch this PC just upload the iso to Pi KVM

34
00:02:40,319 --> 00:02:46,200
choose the mode you want to use click connect and you're done it can even

35
00:02:44,640 --> 00:02:50,040
download images from the internet if you give it an address for you family it

36
00:02:48,540 --> 00:02:53,940
gurus out there that means you could remotely diagnose and repair just about

37
00:02:51,900 --> 00:02:57,900
any problem you're less Savvy relatives might have without having to guide them

38
00:02:55,920 --> 00:03:01,980
through the scary outside of Windows stuff that they've never seen before and

39
00:02:59,760 --> 00:03:06,780
I can't tell you how many times I've had to do that especially as a Geek Squad

40
00:03:04,140 --> 00:03:11,400
guy like trying to talk to somebody on the phone who had no idea what anything

41
00:03:08,580 --> 00:03:17,340
was I I didn't know who they were and yeah of course that might bring up some

42
00:03:15,239 --> 00:03:21,900
privacy concerns so maybe you could have them leave it disconnected until they

43
00:03:20,040 --> 00:03:25,500
need you to make a house call you can always configure it with tailscale vpn's

44
00:03:23,760 --> 00:03:29,099
free personal plan so you can access it as soon as it connects without having to

45
00:03:27,360 --> 00:03:34,920
worry about networking Shenanigans like static IP addresses or port forwarding

46
00:03:30,900 --> 00:03:36,379
but okay we've seen what it can do how

47
00:03:34,920 --> 00:03:42,060
does it work inside this unassuming little box is a

48
00:03:39,599 --> 00:03:47,040
Raspberry Pi 4 and a specialized hat that provides not only a USB connection

49
00:03:43,920 --> 00:03:49,860
and HDMI output but also three total

50
00:03:47,040 --> 00:03:53,040
RJ45 Network Jacks the one on the pi itself is to connect to your local

51
00:03:51,180 --> 00:03:57,720
network via Ethernet as you'd expect and Wi-Fi is also available though the steel

52
00:03:55,920 --> 00:04:02,000
chassis you have here is a little bad for signal strength but the other

53
00:03:59,760 --> 00:04:06,000
Ethernet ports on the hat are special the one directly above the pies can

54
00:04:04,680 --> 00:04:09,120
connect to a Serial port with a converter cable if for example you

55
00:04:08,040 --> 00:04:15,120
wanted to be able to directly control the pi KVM from the machine it's connected to or communicate with a

56
00:04:13,140 --> 00:04:18,299
battery backed UPS or other serial control device the port on the other

57
00:04:17,400 --> 00:04:24,660
side this is meant for this optional breakout

58
00:04:21,419 --> 00:04:26,340
board called the ATX adapter as you can

59
00:04:24,660 --> 00:04:30,780
probably tell by the lack of electronics on the adapter itself it's not truly

60
00:04:28,620 --> 00:04:33,780
Ethernet but instead it's breaking up the wires in an Ethernet cable to

61
00:04:32,520 --> 00:04:41,759
directly hook up to the motherboard's front panel connectors so you've got your power your reset and the power in

62
00:04:37,979 --> 00:04:43,740
HDD lids this secondary board has two

63
00:04:41,759 --> 00:04:48,000
sets of pins one set goes to the front panel header itself as you see here and

64
00:04:46,020 --> 00:04:51,540
the other goes to the cables from your case so you don't lose out on any

65
00:04:49,320 --> 00:04:55,020
functionality depending on how neat you want it to be there's enough length on

66
00:04:53,220 --> 00:04:59,940
these cables that you can actually use a 3D printed PCI bracket to mount the ATX

67
00:04:57,600 --> 00:05:04,080
adapter directly inside your case or you can just let it dangle and fish

68
00:05:02,280 --> 00:05:10,440
the Ethernet cable through a suitable opening like a PCI slot though some BHB

69
00:05:07,860 --> 00:05:15,000
tape will probably go a long way to both insulating the bare contacts on this

70
00:05:12,120 --> 00:05:19,680
thing and keeping it safely in place but all this is wired up you've got a

71
00:05:16,860 --> 00:05:23,580
perfectly functional normal PC that can be controlled anywhere

72
00:05:21,240 --> 00:05:27,360
or at least we're part way there if you bought the whole kit like this then

73
00:05:25,259 --> 00:05:30,900
you're already good to go but if you just have your pie in a hat you'll need

74
00:05:28,800 --> 00:05:33,720
to do some setup first flashing the memory card is a simple matter of

75
00:05:32,160 --> 00:05:37,560
downloading the image using our PI imager or your favorite Imaging tool

76
00:05:35,220 --> 00:05:42,240
inserting the SD card and hitting right pop the SD card into the pie attach the

77
00:05:40,259 --> 00:05:46,259
hat if you haven't already plug it into your network and power it up once it's

78
00:05:44,460 --> 00:05:50,340
booted you'll see um well not much while you might be able

79
00:05:48,960 --> 00:05:54,780
to get away with connecting your web browser to Pi kvm.local you'll probably

80
00:05:52,860 --> 00:05:58,860
have to find out what IP address the pi KVM grabbed the easiest way to do that

81
00:05:57,000 --> 00:06:03,900
is if you've got the whole kit or picked up the OLED display it'll save right on

82
00:06:00,960 --> 00:06:07,680
it but the next best thing is to take a look at your router's DHCP assignments

83
00:06:05,820 --> 00:06:11,639
if you don't have access to that or you're not sure how you can instead use

84
00:06:09,840 --> 00:06:15,240
this command to Output a list of devices on your network look for one with a Mac

85
00:06:13,680 --> 00:06:18,840
address containing these patterns and you'll find the IP address next to it

86
00:06:17,280 --> 00:06:22,440
punch it into your browser and you're Off to the Races you'll definitely want

87
00:06:20,820 --> 00:06:26,039
to change these default admin passwords before you go any further though and you

88
00:06:24,419 --> 00:06:30,660
can do that by going to the web terminal and entering these commands

89
00:06:27,780 --> 00:06:35,759
now comes the real magic from the main menu click on KVM and you'll be whisked

90
00:06:34,020 --> 00:06:40,979
away to a streamlined interface that might make it admins think of ipmi which

91
00:06:38,400 --> 00:06:44,880
is fitting because that's basically what we got here if you click on the ATX menu

92
00:06:43,380 --> 00:06:48,720
here you can see that you have power and

93
00:06:46,860 --> 00:06:51,600
reset buttons as if you were right next to the PC I can turn it off just like

94
00:06:50,340 --> 00:06:55,620
this and that it goes if you've connected

95
00:06:53,940 --> 00:06:59,940
everything right and you hit that button while it's all off you'll see the boot

96
00:06:57,539 --> 00:07:04,620
sequence right in your web browser it's pretty cool but what did it cost if you

97
00:07:03,000 --> 00:07:09,060
don't care for fancy things like a case but you also want everything all in one

98
00:07:06,660 --> 00:07:14,160
you can get just the custom hat for your pie for 160 us buckaroons

99
00:07:11,699 --> 00:07:18,120
but if you do want the whole package you can get them pre-assembled like this

100
00:07:15,479 --> 00:07:23,819
with the case cooler OLED display 2gig Raspberry Pi 4 and a 32 gig pre-imaged

101
00:07:21,000 --> 00:07:28,020
SD card for an extra 90 bucks for a total of 250 dollars is that a good

102
00:07:26,220 --> 00:07:31,560
price kind of feels like it to me commercial

103
00:07:30,000 --> 00:07:37,199
options from the big boys run between 500 and a thousand dollars US

104
00:07:34,860 --> 00:07:41,940
the only obvious comparison is the also open source tiny pilot Voyager 2. a

105
00:07:39,840 --> 00:07:45,840
similar Pi powered concept wrapped in a more polished commercial package with

106
00:07:43,919 --> 00:07:50,160
some extra features that sells for 360 dollars for the it manager looking for

107
00:07:48,539 --> 00:07:53,699
something for their server racks the commercial tiny pilot claims to have a

108
00:07:51,960 --> 00:07:58,500
superior support system and while I haven't used either support system

109
00:07:55,919 --> 00:08:01,860
I degree in principle Discord servers are great for building communities but

110
00:08:00,240 --> 00:08:04,860
bad for searchability and you can fight me on that the best part about all of

111
00:08:03,840 --> 00:08:10,319
this though you're not shy about getting your hands

112
00:08:07,319 --> 00:08:12,419
dirty you can build your very own Pi KVM

113
00:08:10,319 --> 00:08:17,580
or tiny pilot and if you don't care about bells and whistles like Ethernet

114
00:08:14,400 --> 00:08:19,860
support or the ATX power control you can

115
00:08:17,580 --> 00:08:26,160
actually build it with a Raspberry Pi zero two w with no soldering for around

116
00:08:23,099 --> 00:08:27,840
fifty dollars unfortunately Raspberry

117
00:08:26,160 --> 00:08:31,800
Pi's are still tough to find right now and the DIY route is significantly less

118
00:08:30,539 --> 00:08:37,860
polished than either of the other options which are still available

119
00:08:35,279 --> 00:08:42,060
so if you're not looking to DIY the full Pi KVM package here for my money anyway

120
00:08:40,260 --> 00:08:46,860
strikes an excellent middle ground it takes nearly every box just like our
