Worklog An attempt to recreate the PS2 PCB

[Mister M]

¡El trabajo que hizo es increíble! ¡Me sorprendió 100%! ¡Ingeniería inversa y todo ese trabajo! Ahora mi duda ¿utilizará 7.3v en toda la placa? ¡He visto colegas que ejecutaron el sistema a 5v y funcionan bastante bien! así que estudie solo el dac de audio y el joystick usan 7.3v; Los motores vibratorios usan 5v aunque los joysticks llegan a 7v, el procesador envía 5v a una resistencia y esta baja su voltaje en un 40%, llegando al motor con un mínimo de 0,60v y un máximo de 3,08v. ¡Vibración! y lo negativo o masa es la variable!, lo positivo va directo! Y mi última pregunta, ¿se venderán las planchas o limas? ¡Tengo muchas ganas de trasplantar todo a tu creación! ya que tengo varios 90k para probar! Ahora mismo estoy armando uno pero recortado! ¡Y me resulta un poco difícil sin microscopio!

"The work you did is amazing! i was 100% amazed! reverse engineered and all that work! Now my doubt will you use 7.3v throughout the board? I have seen colleagues who ran the system at 5v and they work quite well! so study only the audio dac and joystick use 7.3v; The vibrating motors use 5v although the joysticks go to 7v, the processor sends 5v to a resistor and this lowers its voltage by 40%, reaching the motor with a minimum of 0.60v and a maximum of 3.08v. vibration! and the negative or mass is the variable!, the positive goes direct! And my last question, will the irons or files be sold, I'm looking forward to transplanting everything to your creation! as I have several 90k's to test! I'm putting one together right now but trimmed! And I'm finding it a bit difficult without a microscope!"

I'm using custom regulators created by @Gman, the board is powered via USB-C at 5V 3.1A, this power is managed by an IC IP2721-D, which in turn powers the Texas instruments BMS, as it is a portable PS2 , I prioritized reducing consumption and weight of the console, so I will not use engines. And I have a mod that lowers the EE consumption and consequently the EE temperature.

Vibration! and the negative or mass is the variable!, the positive goes direct! And my last question, will the plates or files be sold? I really want to transplant everything to your creation! since I have several 90k to try! Right now I'm putting one together but cut down! and it's a bit difficult for me without a microscope!

Estoy usando reguladores personalizados creados por @Gman, la placa se alimenta vía USB-C a 5V 3.1A, esta energía es administrada por un IC IP2721-D, que a su vez alimenta el Texas Instrumentos BMS, al tratarse de una PS2 portátil, prioricé reducir el consumo y el peso de la consola, por lo que no utilizaré motores. Y tengo un mod que baja el consumo de EE y en consecuencia la temperatura de EE.

I had translated it into English but my automatic translator had translated it into Spanish! apologies! now excellent when using 5v and already done consumption tests! ? in games like god of war? And regarding the DAC audio? And in its design are there options to pull a 5v voltage line to the joystick? I'm interested in the vibration option! Is it more immersive and can the pcb design be obtained? and what is the low consumption mod?

Driver layar, IC penguat audio opsional, dan STM32 untuk kontrol PS2. Ini hanya draf, banyak yang akan berubah.

Is this pcb finished? If it is finished, I would like to request the pcb file. I really want this pcb. Please, my friend. I have wanted to have my own ps2 portable for a long time.

The video driver board is on my Github, along with the mapping and reverse engineering, and production files. I talked more about it here on bitbuilt, in this post: https://bitbuilt.net/forums/index.php?threads/driver-lcd-rtd2660h.6493/

PS2 Development Has Not Stopped! New Projects, New Tools, and Much More to Come

I know I am years behind schedule with the development of my project, but that does not mean I have stopped or given up on researching, studying, and developing for the PlayStation 2.

I still do not know whether I should start a new work log or continue with this one. Since I have not completed anything yet and continue to work steadily on several projects involving the PS2, I believe I will keep sharing my progress here.

Well, I gave up on the competition, but I did not give up on working. On the contrary: I decided to challenge myself, started from scratch, and went after new knowledge. I learned how to use KiCad, since I had previously worked only with EasyEDA.

In addition, I am developing software that is becoming a reverse-engineering MCP and a complete digital-twin system for printed circuit boards (PCBs). The idea is for you to scan the board and take measurements using specific tools that I am also developing. At the end of the process, it will be possible to obtain an extremely accurate digital twin of the board, with all of its components and other elements properly represented.

The project is still under development, and there is no release date yet.

One of the tools I am developing is a bed of nails, which will make it possible to perform various measurements and tests directly on the board, without having to keep soldering wires or manually using tools for each measurement. The goal is to make this process much more practical, precise, and automated.

As I said, I have not stopped or given up! I would like to share some of the progress I have been making with you.

One of the projects is the development of a new video chip for the PlayStation 2: the NEXUS VISION. It will use a low-cost FPGA and feature numerous functions and improvements. At the moment, we already have video output via HDMI, but the idea is to go far beyond that. In the future, I want to expand compatibility to virtually all types of displays and technologies available, including MIPI, TFT, eDP, and others.

I am also developing a new BIOS chip using the RP2350B, called Nexus Core. It is already working, and a BIOS with USB update capability is now a reality! In addition, I am working on other features. My competition post is specifically about part of this work, although I decided to withdraw from the competition.

For now, I will leave you with some images so you can follow the progress.

The test bench is not the prettiest, but it is 100% functional, and that is what matters at this point. The video signal still has two RGB bit wires disconnected, which slightly affects the image quality. But that is merely a matter of soldering and adjustment.

The PlayStation 2 will not stop evolving! There is still much to explore, many improvements to develop, and many projects ahead.

This is only part of what I am preparing. There is still a lot of work ahead, and I hope to be able to share more and more progress with you!
