I did the LED mod. I also recently added a switching regulator (it improved the battery consumption somewhat) as an exercise.Houdini wrote:did you do the LED mod?
If so then how would you connect the ps1 screen if you didnt do the LED Mod (pic?) Thanks a lot !!!!
The screen hooks up the same whether you modify with LEDs or not--it runs on 7.2 V (hook up the (+) to the 7.2 V spot on the board and pick a ground site anywhere convienient)--but without the LED mod, the existing light source will only give you a lot less gameplay time.
Only the great ones remember.

Since you won't need to save the expansion slot adapter--you can destroy it. I used solder wick to remove as much solder as I could from the back of the adapter. If you cut away the plastic housing on the adapter, you could remove the pins one-by-one, which is easier than trying to rock the whole assembly loose, where you will risk damaging the traces on the board.shmagoogin77 wrote:i have a question about the original snes board
how do you desolder the expansion slot
Only the great ones remember.

I'm interested in how you made the switching regulator for the 5v line. All I could see was an 8pin DIP... How could a switching reg. be integrated into such a small package? I was considering a MAX787 for mine but it needs too many passive components. (Inductors are also a pain to get.)
So, how did you work that out?

Posted new pictures!!!
The pictures that you saw were older pics. I just uploaded recent photos of my snesp. I was able to fit everything on small circuit board. I located it up towards the top curved section on the unit.marshallh wrote:I'm interested in how you made the switching regulator for the 5v line. All I could see was an 8pin DIP...

I bought the switching regulator from digikey--because they provided good documentation. Somewhere--it suggest what components can be applied and a schematic is provided.
I purchased all of the supporting components from allied electronics. It does add about 30 minutes of gameplay.
When I built the regulator--I first built it on the breadboard that you saw the chip on and testing it is as obvious as measuring the input and output voltage.
Important note: when you solder your final regulator together, make sure that you keep the wiring as short as possible!--I tried moving the large input capacitor, and it altered the output voltage to 3.2V.
