SONY non-official mods
I made an integrated PS4.
The name is PlayStation4 Unify.
Please call him "PS4U".
Same as my work PS2U, the concept of "All loaded"
Weight and size are greater than PS2U.
Ah... maybe it's bigger than your imagination.
Let's explain the function.
15.6" full HD IPS LCD

That's the laptop type this time.
Lightly small... I can not do it. So, I will make it possible to play without holding by hand.(Reflection point of PS2U)
On the other hand, since the theme of "integrated type" is absolutely abandoned, I made it possible to accommodate the controller.
In the later production series, please see the hardships to realize that.
Also, those who are not very good at electric construction... Enjoy the videos only in the atmosphere.
Don't worry! Even for me who made this, there is a part "I do not know well, but it is working.lol"
Let's start. The third volume of the KEI STUDIO MODs series. It is PlayStation4 Unify -PS4U-!
Kei...
Hey, Kei. Look this.
Grandpa, what is this?
This is called "semiconductor".
Semiconductor...?
so. This is a part that connects and disconnects electricity.
It conducts or does not conduct, ...half.
Because it is half, it is called a semiconductor. Interesting, right?
Hmm.
There is a "NOT circuit" in this IC...
I..C..?NOT...?
When there is signal does not flow electricity.
When there is no signal flow electricity.
"1" is "0"... "0" is "1"...This says so.
This is such a twisted person.
???
(It is difficult and I don't know well... )
I will give this to Kei.
I will not use it anymore...
(Even if I get such a thing... )
...How do use this?
Hey... Grandpa.
Huh...? Grandpa?
...!
Oops...
It seems that I have fallen asleep because my editing work on the video was painful.
I am old huh... I reworked my mind and started electric work editing.
Firstly from necessary items, but...
A status window is displayed at the upper left.
When PS2U, because there were many questions "How much did it cost?"
Let's go then!
PS4Slim(CUH-2000)
GeChic On-Lap 1503H monitor
PlayStationCamera
COUGAR 200K keyboard
Connect them and test them.
It is OK! Of course.
Power consumption is around 90 W at the peak.
It was roughly the same as the numerical value of the preliminary survey.
I want to reduce power consumption even a little. For that, I will convert from HDD to SSD. Transcend SSD 480GB
It decreased about 4 - 6W.
And PS4 main unit...
Because it is a very sophisticated packaging, there are few useless parts.
However, this parallelogram silhouette seems to have a little room for dieting.
Firstly disassemble PS4.
Almost all parts are installed in this intermediate frame as we introduced in the previous video.
Cut this frame further...
I dieted it.
Reassemble to the frame again.
I can not make it smaller any more. (... so, I think)
Once, it confirms operation. It is OK!
Umm... it is about 50W even at low load.
No match for PS2.
For example, how big a battery is needed to run this PS4 for several hours?
However, if I want to claim integrated type, it need to install a battery.
...Otherwise, it is much smarter to buy even a dedicated monitor.
Well, the battery is the rechargeable pond that is also in the smartphone as you all know.
If you run out of electricity from the battery you will not be able to use your smartphone.
When an external power supply is connected, power is supplied from there.
And it charges the battery with the remaining electric power.
Thanks to the battery backup circuit, it is possible to smoothly switch this power supply.
Let's do this with PS4.
I checked the PS4 power supply.
PS4 power supply is two lines.
One is 4.8V of a small connector of 4 pins.
The other is 12V of a huge connector.
This is a large capacity of 13A(ampere).
However, it is all about power supply to PS4. There is not enough power to charge the battery.
A large power supply that enables PS4 operation and charging to a large capacity battery is necessary.
For example, replacing the power supply with that for a large gaming note PC ...
Furthermore, a DC/DC converter is prepared. I call it "decodeco" here.
And what if I extract the necessary voltage from the AC adapter through decodeco?
If I enter them directly...
As a result, this alone does not work well.
why. Let's pay attention to the 4pin connector of PS4 power supply.
Breakdown of 4pins...
"ACIN_DET"is AC100V detection signal
"ACDC_STBY"is signal from PS4
"Ground"
"5VSB" is 4.8V sub power supply.
PS4 and power are exchanged by these mutual signals.
"Ah! Tell the PS4 to the outlet!"
"Oh? The signal came from the power supply"
Nothing particularly happens any more at this point.
Let's play a game♪
"Ah! Power button pressed"
"I have to prepare to startup"
Preparing to startup.
"All right! Preparation for startup OK"
"I have to inform power supply..."
"PS4 seems to be ready!"
"Yes! Yeah!"
"Let's stop it. PS4 power OFF"
"Oh! Power off was selected!"
"I have to termination processing"
"All right! Termination processing completed"
"Let's stop signaling because I don't need 12V anymore!"
"The signal from PS4 has disappeared! 12V stop!"
"Good night"
Without such interaction, PS4 will not operate properly.
4.8V may be supplied at all times, but ...
Control timing is required to supply 12V. "Control part 1"
This is the first task.
Another one task is battery operation.
These are battery, charge and discharge management boards.
Does it look like a car battery? Because PS4 is the target.
When the AC adapter is connected...
Two lines power supply to PS4 and...
It is charging the battery at the same time.
When the external power supply is disconnected...
Switch between input and output wiring of charge and discharge management board.
Like this
External power drive.
Switching...
Battery operated.
This switching seamlessly...
In other words, It need a circuit to control without power failure.
This is another one task. "Control part 2"
I will resume parts collection to fulfill that control.
msi AC Adapter for Gaming Note PC
Step-up and step-down decode deco (for 12V)
Charge and discharge management board
Battery fuel gauge
Well, I'd like to take out electricity from the AC adapter...
This male connector that looks like a DIN connector can not be found on the market at all.
I have to make something that does not exist. This was the first DIY in PS4U.
Tackle the junk connector I bought at the recycle store...
Voltage can be taken out from 330W monster AC adapter.
The key battery is Panasonic 's lithium ion which was also used in PS2U.
Capacity, safety, availability, price, manageability etc...
When considering balance, there were no other options.
The price was 990yen per one.
In the shop I bought this time, it enters 2 pieces in one box.
When it was PS2U, it was 8 pieces.
Eating big PS4 is not satisfied with this.
So, another one set!
eh! What? Are you still missing out?
How about this?
No good!? What? take it...!!
48 pieces!!
Umm... nice scenery!
48 pieces battery so... let's call it "BAT48".
Panasonic Li-ion rechargeable battery 3400mAh
I bought various besides these but...
Since it takes time to introduce everything, I will summarize the cost.
Miscellaneous costs related to power supply
This is off the topic, but...
PS4U is an integral type, and is a laptop PC type.
So, this is installed with a keyboard or equipping a controller.
I want to produce a fun gadget feeling.
But PS4 Slim's scalability is poor. Only 2 USB ports on which we can rely on.
They finish work with keyboard and controller.
So, install them via 3 mouths USB hub.
Then it can secure two free USB connectors.
I want to leave to some extent the usability of the actual machine even if it is difficult.
Those who are "Free part 2" will become via hub · · ·
I will secure the power supply separately, I want you to forgive it because it makes it self-powered. ...That's why I prepared a 3 mouths USB hub.
ELECOM USB hub(3 mouths)
Dismantle immediately...
Now this.
I said that the usability of the actual machine... but I also want to connect to the TV.
HDMI OUT is secured with the HDMI splitter.
AUKEY HDMI splitter
Output to the TV is also possible.
I will make a battery pack.
The weight per battery is about 45.7g. I don't want to talk about gross weight.
They challenge PS4 in 4 serial 12 parallel.
This time is a power control circuit using MOS-FET.
MOS-FET is easy to handle large current and switching speed is high.
Control part 1... It controls 12V and starts up successfully.
Dragon Quest Heroes 2 by BAT48!
"Control part 1 Clear"
"It moved firmly." It seemed that the production was going well.
It was MOS-FET that burned up. Those close to the charging connector on the charge and discharge management board.
Anyway it is high power.An erroneous circuit vomits a flame.
The burned MOS-FET can be replaced with a new one. The biggest problem than that...
I do not know what was wrong
...It is due to my lack of study.
There is no problem if only battery discharge. There is no problem if only battery charge too.
But when charging and supplying from external power source were done at the same time, it burned.
Why...?
...what!?
Resistors here...?
Discharge side ground and charging side ground. There is a resistors between them.
...Is there a potential difference between each ground?
Everything is an amateur of electricity. I was thinking that ground was 0V.
So simply join decodeco circuit and ground. ...The results is short circuit.
Well, at the time of charging, it is necessary to completely shut off the circuit with the discharge side....
That is, when disconnecting the discharge side circuit when connecting the AC adapter...
After connecting, stop electricity...
Don't output after inputting...
"0" is "1"
"1" is "0"
Is this a "NOT circuit"?
I have reworked the power supply control circuit.
Semiconductor sleeping in the tool box for about 30 years.
I incorporated my grandfather's NOT circuit IC.
And this time I personally used fast switching control with MOS-FET for the first time.
When switching between battery and external power supply. Even in a high-speed MOS-FET, there is a momentary blackout.
This electrolytic capacitor compensates for the power failure.
An electrolytic capacitor is a parts that can instantaneously discharge stored electric charge.
A large capacity of 35200μF prepares for power outage at the time of switching.
Even though it is a moment, the power of PS4 is quite different from that of smartphones.
...Now, preparation is complete.
Please! This time move it...
Continue to Part 2...
