00:00:00.000 --> 00:00:07.200
pretty much everyone agrees that the convenience of having one USBC power

00:00:04.500 --> 00:00:11.460
adapter for all of your devices is a good thing but what about the year's

00:00:09.599 --> 00:00:16.859
worth of gadgets we've accumulated that don't support USBC there's a solution

00:00:14.280 --> 00:00:22.560
for that to demonstrate we are going to take all of these retro consoles and

00:00:20.279 --> 00:00:27.599
bring them into the 21st century using Gan Chargers with USBC from ugreen who

00:00:25.619 --> 00:00:32.099
sponsored this video no more bulky power adapters no more cable clutter no more

00:00:30.180 --> 00:00:36.899
struggling to find Reliable Replacements and what's really cool is that you can

00:00:34.440 --> 00:00:41.700
do this on just about any device that accepts DC power even if it has a barrel

00:00:39.480 --> 00:00:45.180
plug we're talking monitors laptops routers neck massagers electronic dogs

00:00:43.379 --> 00:00:48.719
small fans external hard drive security cameras picture frames Network switches

00:00:47.100 --> 00:00:51.140
electronic dog garage door sensors Networks

00:00:55.399 --> 00:01:02.219
USBC is understandably confusing there are multiple standards for data multiple

00:01:00.180 --> 00:01:06.960
standards for power cross compatibility that works except when it doesn't except

00:01:04.379 --> 00:01:12.720
when it does but unofficially and we endure this because ultimately it's

00:01:09.479 --> 00:01:15.780
still a lot better than the alternative

00:01:12.720 --> 00:01:18.000
the focus of today's video USB PD or

00:01:15.780 --> 00:01:23.159
power delivery is just such a perfect example of this because some of its

00:01:20.580 --> 00:01:30.840
features are optional it's common to run into products that support USB PD but

00:01:26.640 --> 00:01:32.640
not all of USB PD more on that later for

00:01:30.840 --> 00:01:37.020
now let's talk about how it's supposed to work because it's really really cool

00:01:34.680 --> 00:01:42.900
out of a single wall adapter and cable you can get output from 5 to 20 volts

00:01:40.140 --> 00:01:46.200
even 48 volts on the latest version and you don't have to worry about getting

00:01:44.220 --> 00:01:51.360
the voltage wrong because it just figures out what your device needs when

00:01:47.880 --> 00:01:53.159
you plug it in like magic right no not

00:01:51.360 --> 00:01:56.520
like magic magic isn't real and magicians are Shifty swindlers who steal

00:01:55.020 --> 00:02:01.560
your ear quarters what we need here then is science in

00:01:59.280 --> 00:02:05.460
order to determine the correct voltage a handshake process takes place between

00:02:03.060 --> 00:02:10.860
your charger and your device the charger says hey how many volts do you want I've

00:02:07.860 --> 00:02:12.900
Got 5 9 15 and 20 and the device says

00:02:10.860 --> 00:02:16.680
I'll have 9 volts please they synchronize their watches and Shake

00:02:14.400 --> 00:02:22.319
Hands completing their electric ritual but these old devices are to continue

00:02:19.980 --> 00:02:27.720
our handshake analogy completely handless they have none of the requisite

00:02:25.379 --> 00:02:35.040
circuitry to respond to our charger's inquiry so how do we give them a hand

00:02:31.680 --> 00:02:37.020
well 5 volt is easy if your wall adapter

00:02:35.040 --> 00:02:42.480
detects a certain resistance along the two configuration pins it'll just send

00:02:39.420 --> 00:02:44.700
back 5 volts so two resistors on a USBC

00:02:42.480 --> 00:02:48.840
Port is enough to get you going if you want any higher voltage though you're

00:02:46.560 --> 00:02:54.540
going to need some kind of logic board luckily unlike some competing standards

00:02:51.660 --> 00:02:58.260
like Qualcomm quick charge USB PD is royalty free so these boards are

00:02:56.220 --> 00:03:02.400
plentiful and cheap and it is an open standard so you could even build your

00:03:00.120 --> 00:03:08.220
own to suit your needs and it gets even better these boards can be so small that

00:03:05.400 --> 00:03:12.480
they will fit inside the plug housing of an otherwise normal looking cable like

00:03:10.260 --> 00:03:19.260
this one which is going to be extremely helpful for our use case the NES super

00:03:15.659 --> 00:03:21.720
famicom and Sega Genesis all use 5.5 by

00:03:19.260 --> 00:03:25.440
2.1 millimeter Barrel Jacks the worldwide Super Nintendo used a larger

00:03:23.640 --> 00:03:28.739
Jack for whatever reason I don't know Nintendo logic probably so if you have

00:03:27.360 --> 00:03:33.420
one of those you'll need this inexpensive adapter from console 5. with

00:03:31.379 --> 00:03:38.580
that out of the way these three consoles all use 9 to 10 volt input power and at

00:03:37.080 --> 00:03:44.340
most one and a half amps of current meaning that a solution for one should

00:03:41.099 --> 00:03:45.540
be a solution for all but wait there's a

00:03:44.340 --> 00:03:52.260
bit of variance in their power requirements is that legal actually yes

00:03:49.140 --> 00:03:54.060
if we look inside these consoles not too

00:03:52.260 --> 00:03:59.879
far from the power input we'll find the venerable 7805 voltage regulator 78 is

00:03:57.360 --> 00:04:03.299
the series and o5 is the number of bolts that it outputs and this bad boy which

00:04:01.920 --> 00:04:07.680
has actually been in production for over 50 years can accept input power from

00:04:05.819 --> 00:04:11.879
around 8 volts all the way up to around 12 volts usually or sometimes even as

00:04:10.260 --> 00:04:16.079
high as 20 volts if it has a beefy enough heat sink but then hold on a

00:04:13.739 --> 00:04:20.880
second this raises the question if all the power for the internals is 5 volt

00:04:18.359 --> 00:04:25.919
anyway why not just remove the regulator and then run 5 volt USB power directly

00:04:23.340 --> 00:04:30.300
into the system you actually can do that but you'll need to take some extra

00:04:27.360 --> 00:04:36.419
precautions a 5 volt USB power adapter can actually output anywhere from 4.4 to

00:04:33.380 --> 00:04:39.180
5.2 volt while still being within spec

00:04:36.419 --> 00:04:43.620
and perhaps more importantly that output voltage will fluctuate slightly because

00:04:41.160 --> 00:04:48.660
of the conversion from AC current this fluctuation is called Ripple and it is

00:04:45.780 --> 00:04:52.320
bad for your old electronics so you'd want a step up step down converter like

00:04:50.280 --> 00:04:56.340
this one if you want to go that route we're not going that route we're going

00:04:54.660 --> 00:05:01.680
to take a walk down easy street with one of those cables I showed you before these cost just a few dollars from

00:04:59.820 --> 00:05:05.940
Adafruit and use a built-in chip to request 9 volts from our USB PD wall

00:05:04.199 --> 00:05:09.120
adapter which will certainly be enough for these consoles regardless of what

00:05:07.860 --> 00:05:13.620
their original Power bricks might normally provide

00:05:11.100 --> 00:05:18.060
Gan power adapter not only smaller but it actually has two ports and it'll do a

00:05:15.479 --> 00:05:23.460
12 this is probably 45 Watts hey yep do a total of 45 Watts no movie Magic guys

00:05:21.900 --> 00:05:28.259
we're going straight out of that wall wart into this NES

00:05:26.400 --> 00:05:32.360
the power of this bad boy up shut up shut the front door

00:05:29.759 --> 00:05:32.360
sick

00:05:33.900 --> 00:05:42.120
don't play too long no no I gotta win the whole game yeah oh damn it get it

00:05:39.479 --> 00:05:46.560
together man get it together the people are expecting better from you I need the

00:05:44.820 --> 00:05:51.720
flute no

00:05:48.960 --> 00:05:55.320
no it's the first level the coolest thing about this is not only that we got

00:05:53.400 --> 00:06:01.639
rid of that giant sketchy power adapter but that we're actually able to plug in

00:05:57.539 --> 00:06:03.300
two consoles to a single power adapter

00:06:01.639 --> 00:06:08.639
and remember when I said Power delivery has

00:06:05.580 --> 00:06:12.000
some flaws well it's extremely common

00:06:08.639 --> 00:06:14.340
for PD Chargers especially compact Gan

00:06:12.000 --> 00:06:19.020
Chargers to pause power to their already connected devices when a new one gets

00:06:16.620 --> 00:06:24.600
plugged in they then perform a fresh handshake with every connected device so

00:06:21.960 --> 00:06:30.780
you can see this in action yeah short pause and power and it's back

00:06:28.139 --> 00:06:35.340
to be clear this is a feature not a bug it helps ensure that you can't ask a

00:06:33.360 --> 00:06:40.259
charger to Output more than its capabilities safety first but it is a

00:06:38.639 --> 00:06:45.600
little inconvenient for devices like these that don't have a battery in them

00:06:42.720 --> 00:06:49.500
since I lost my spot in the game we might as well swap out this 45 watt

00:06:47.639 --> 00:06:54.000
charger so we can power all three of these consoles at once super cool and

00:06:52.139 --> 00:06:57.419
it's actually smaller than that crappy adapter that was only able to do one of

00:06:56.100 --> 00:07:03.180
these consoles but wait there's more quick note while

00:07:00.660 --> 00:07:07.979
this super famicom in Genesis do share a barrel Jack size with the NES and their

00:07:05.460 --> 00:07:12.720
power bricks will work with the NES and with each other that comes with a slight

00:07:10.199 --> 00:07:17.880
caveat super famicon and Genesis Barrel Jacks are negative polarity so basically

00:07:15.840 --> 00:07:22.259
it means the positive and negative are swapped around from where they are on a

00:07:19.740 --> 00:07:26.520
typical Barrel Jack for this reason they will not work with these cables unless a

00:07:24.599 --> 00:07:30.720
polarity converter is used while discovering this did not damage our

00:07:28.139 --> 00:07:36.840
systems yours might not be so lucky you have been warned we've got these these

00:07:34.080 --> 00:07:42.539
newer consoles have AC power plugs so you might think surely they're not gonna

00:07:39.319 --> 00:07:45.419
yeah we are due to the nature of silicon

00:07:42.539 --> 00:07:51.660
transistors AC wall power must be converted to DC so all we need to do is

00:07:48.840 --> 00:07:56.039
remove that internal AC to DC power supply and replace it with one that

00:07:54.060 --> 00:08:01.199
accepts 12 volt DC power from our wall adapter and converts to the 3.35 and 12

00:07:59.280 --> 00:08:04.919
volt juice that our consoles drink conveniently there's a fairly active

00:08:03.479 --> 00:08:09.240
community of modders who are building exactly what we need and out of these

00:08:07.560 --> 00:08:14.880
ones that we purchased from game Tech us only the N64 one requires any soldering

00:08:12.539 --> 00:08:18.000
at all and even then that's only if you want to put it back to stock again now

00:08:16.680 --> 00:08:22.800
that they're all installed then they take the same standard Barrel Jack size

00:08:19.979 --> 00:08:27.660
that the other three consoles take which is kind of a dangerous thing proceed

00:08:25.740 --> 00:08:32.459
with caution here because while they're the same size they are not the same

00:08:30.240 --> 00:08:37.860
voltage you might have noticed that when I listed the voltages supported by USB

00:08:34.919 --> 00:08:43.200
PD earlier I didn't mention 12 volt specifically that's because while the PD

00:08:40.440 --> 00:08:48.899
spec does include support for 12 volt it's not required and a lot of

00:08:45.420 --> 00:08:51.180
Manufacturers skip it thankfully since

00:08:48.899 --> 00:08:55.200
we're using ugreen nexo Chargers we don't have to worry about that every Gan

00:08:53.279 --> 00:09:00.360
charger in their lineup supports 12 volt power delivery but you might say what

00:08:58.380 --> 00:09:05.640
about using other cables I mean one of the big selling points of USBC is that

00:09:02.940 --> 00:09:10.260
you can use one cable for a ton of different things and just plug that type

00:09:07.500 --> 00:09:14.100
c connector into everything well on these modded consoles you could achieve

00:09:12.120 --> 00:09:17.399
that by removing the barrel Jack and then installing a trigger board there

00:09:15.899 --> 00:09:22.140
are some resources online for 3D printing a triggerboard but that

00:09:19.500 --> 00:09:26.519
requires soldering and it's just easier if we find an alternative method the N64

00:09:24.839 --> 00:09:31.860
in particular has a lot of room for activities in its giant removable power

00:09:28.620 --> 00:09:34.800
supply so this is a panel Mount USBC

00:09:31.860 --> 00:09:38.160
Port just plug a cable into one end plug in a cable to the other end and it's

00:09:36.600 --> 00:09:42.000
done you just have to drill some holes tape up or shrink wrap the metal parts

00:09:40.680 --> 00:09:48.420
to keep them from shorting when it's jostled and install and now everything

00:09:45.300 --> 00:09:51.500
is running off of USBC

00:09:48.420 --> 00:09:51.500
we know this isn't everything

00:09:52.200 --> 00:09:58.920
enough we need everything running off of USBC

00:09:56.820 --> 00:10:06.740
monitors typically use anywhere from 12 to 20 volt power boom USBC network

00:10:01.920 --> 00:10:09.660
switch done this thing USBC okay

00:10:06.740 --> 00:10:15.120
everything is Type C now so why don't I feel complete

00:10:13.080 --> 00:10:18.720
probably because I haven't told you this message from our sponsor

00:10:17.279 --> 00:10:22.920
ugreen provided all of the power adapters and sponsored this video and

00:10:20.820 --> 00:10:26.640
they've got huge black Friday discounts that you guys are going to want to check

00:10:23.940 --> 00:10:29.880
out down below if you're not convinced yet and you want to see even more

00:10:28.200 --> 00:10:34.860
reasons why you should type CFI everything check out that time we made

00:10:31.800 --> 00:10:36.440
James manually plug USB cables in over

00:10:34.860 --> 00:10:41.360
and over again to test their durability USBC ended up being really awesome
