Once it goes into production the V2 should be pretty much ok (hopefully) added pins cc1 and 2 to test fast charging (the original module from aliexpress gets very hot at 20w), in that case solder a small resistor and block the module from accepting 5v 2.5a. added the 4th pin for the LEDs "just...

Ok, that's clearer now. I imagine you'll keep the card like this. If you have the skills to trim it, you can use a PMS to optimize battery life. If you want to leave everything like this, try: at the output of the battery protection circuit you start with the two regulators and not in cascade...

Hi, if you tell us your final goal we can help you better, do you need to build a portable or do you just want an external battery that will power up your PS2?

Hi all small update: I forgot that for the cc1 and cc2 lines you need a resistor of 5 or 10k but towards vbus (so 5v) and not towards ground otherwise the integrated "sleeps" also confirmed that you need mosfets with vgs 0.9v like the ones unsoldered from the original module that I currently...

Hi guys, let's say the table should be more or less like this: 1,25v --> max 0.95v The little "bestiolino" is set to around 0.975v which drops by 0.15v-0.20v under load. Both this and my 79001 work without problems. 1.75v --> max 1.5v (I'm testing it) 2.5v --> as said by legend at 1.8v NB: my...

Hi guys, last (hopefully lol) and small update: after the development of "bestiolino" I took the opportunity to order everything to go with U-amp and so I decided to do this update the u-amp seems to work correctly even without ivdd at 1.8v (disconnected) due to problems in passing 1.8v from...

Hi guys, some small updates on the trimmed 90004, with dualshock, 1 memory card and the mx4sio: Idle: 4,42V x 0,993A --> 4,39W Outrun demo menù : 4,42V x 1,043A --> 4,61W Outrun 2006 in Game : 4,42V x 1,082A --> 4,78W I'd say it currently looks like it's "broken" the 5W limit! obviously...

It's an N-channel MOSFET, model: AO4830. You can also get it from different PS2 Slim models.

Bestiolino "Full": currently in development / debugging ready for release "Full" beast as the word suggests represents a real all-in-one PMS, let's study it more closely: TPS62816 --> the heart of the "Nano" 6A maximum for cpu/gpu core TPS628438 --> the replacement for the ldo there are 3...

Hi guys, while working on my project lately I developed two options, one "custom" and the other "complete" for portable applications. It has currently been developed and tested on the PlayStation 2, but obviously if it reflects the settings for other consoles it can also be used for them. At the...

if it works don't touch it cit

Hi guys, it's been a while but it's time to reveal the end of the project: As per the previous preview, I purchased a used 3D printer, and it was the first obstacle I faced with all the calibrations, tests, and issues with the machine. Once I overcame these and after using a few kg of filament...

Hi guys, it's been a while. I'm hard at work on the case and the surrounding components. I'd say I should be able to finish everything by the end of the month at the latest (fingers crossed). A small spoiler photo: The new case will follow the old one in terms of button layout and style, but in...

Hi guys here is my update after about 20 days: Power regulator: The goal was to try to minimize losses (and there are still others but I'd say I'll be satisfied for now): 1V Rail: For the main power rail here is our protagonist, a board of just about 2.20 euros modified so as to be able to...

It's actually a lot of energy, if you want take a look at my worklog I'm just posting a pretty "massive" update for the regulators, I manage to stay between 8W and 9W, if you can do some tests to understand if you can for example use that PMS directly to the batteries so as to leave the 5v rail...
