Hi, I have been lurking around the forums for a year now and have decided on starting my first portable. I have designed a custom PMS from TI regulators and using two transistors it should be able to turn on and off with a button press. These are my first ever boards I have ever designed so if you see anything I can do better I would love to hear it.
For the screen and audio I will be using the UAMP2 and the screen and driver board from 4Layer. I have the screen running off of 3.3v. For the controls, I plan on using a cheap aftermarket controller with custom boards for the buttons along with switch joysticks.
This is the DPAD board. It has a connector for the joystick, and a ATMEGA32p. I plan on using this for the screen controls and battery fuel gauge. We will see because I am a really bad programmer lol.
Here is the button board. It also has a connector for a joystick. I plan on using the buttons and membranes from a PS2 controller. I might look into casting my own buttons.
I am using the IP271 for PD control as well with Gingers circuit he posted a while ago to be able to access an internal usb drive.
For game loading I will be using the Mange Router (GL-MT300N-V2). MRKane did a bunch of research on it and figured out how to use it without the Ethernet ports or transformers. I through together a board based on the circuit he had..
I have started on designing the case in Fusion. So far I have the front pretty much done and have done a lot of test prints to get the controls right.
A lot of test prints lol.
I did print he whole front to get a feel of the layout and I am really happy with how it is feeling.
I cut up 1 PS2 so far and that is what I have been doing my testing on. I was trying to solder up the USB and I think I shorted something because it will not read the memory card now. I did test the card on another PS2 and it works so I guess I have to cut up another one. It looks like a mess but everything was working.
I have ordered all the PCBs from JLC and they should be here this week along with all the components required. I still need to trim another PS2 and get everything working on it, finish up the modeling and print everything. I still have not decided on a color for the case. There is still a lot of work to be done. I would like to redesign a lot of the boars to use ribbon cables to clean up the wiring but I am not sure if I will have the time. I hope I can finish this for the contest but I am moving across the country sometime in the middle of the contest so I will try by best.
Edit: I forgot a couple of things. For the charger ill be using IP2312. It says it can charge at 3A, we will see. I was looking into designing a charger into my pms but with the shortage, every IC I looked at was out of stock so this was easier. I have 2 3000 mAh lithium polymer batteries that I will be running in parallel.
