The points highlighted in red should provide 8.5 volts

Good thinking!! I would never have thought of that solution. You're really smart!!

In general you can't go wrong with anything from Texas Instruments. I believe the PS2 PSM all TI

May I present, the network adapter and SATA bridge chip board: I am still trying to figure out if the CXD9731AGP chip will even work without the Ethernet chip attached, and whether i should ground the inputs, or leave them floating, or pull them high, or pull them low... It's a real...

@Mister M You're absolutely right!! I will need to length match the traces for the RAM chip bus. Thanks for making sure I knew about that. I probably would have run into some pretty nasty performance issues otherwise. You're the best!

So I know you said you don't care, but if you wanted to eliminated those little gaps on the front of your case, (I assume you print it face down) increase the initial layer flow by 10-20%. I find this makes for a cleaner surface when printing cases like these

Well here is the result of a little over a month's work. There's still a fair bit of place holding going on, but the majority of the core I/O has been routed. What I'm currently figuring out is power domains, which regulators to use, what base voltage to run at, etc. Since there really isn't any...

Hey buddy don't sweat that, if only you knew how many pieces of crap tech I've bought for my projects... Anyway you definitely want to use switching regulators (or buck converters, as they are sometimes known) as they are by far the most efficient, and actually do follow the rule that @Stitches...

DING DING DING!! That's right!! I'll post a preview of the work I've done so far soon, but my trial of DipTrace has once again expired, so I'll need to reinstall Windows before I can do anymore work on it. (And before all you KiCad and EasyEDA and Altium etc. users start telling me how silly...

Apparently even 20 plus years later, there's still a lot of unused chips floating around the market place

No, not quite, but that's a good guess based on what little info I gave

Hey everybody, been a little while, and I thought it was about time I posted what I've been up to lately, but rather than saying, I thought I'd let you all guess, so I'll just leave these here: I credit @Mister M for inspiring me

Ahh very good. Did you find a schematic or something, or are you just that good at board cloning?

Is that screen driver IC an RTD2668 or something similar?

I agree, but if you're set on using flat form factor prismatic cells, check out YDL battery. I bought two of these for my Pi-Boy https://ydlbattery.com/collections/1400mah-2000mah/products/3-7v-1500mah-803450-lithium-polymer-ion-battery

My guy!!! That's absolutely beautiful work!!! Brilliant case design, looks like it prints very nicely, do you use some kind of dissolvable support material? I can't say enough about how impressed I am by this!!!

Something wrong with the nozzle?

Nice!! Is that ABS plastic?

Can you show us pictures of the driver board the screen already has?

The thing about the stock regulators is that they assume the presence of a disc drive, where as PS2+ does not, and as a result doesn't convert as much power at once, which is much more in tune with a USB drive, so I would personally recommend you get one, it's the kind of thing I would have...
