Vga Box For Xbox

I suggest you do a search for the Max4383 and LM1881, you should be able to find places to get free samples.  you only need one of each chip (a Max 4383 chip will have 3 or 4 op-amps on it).  The resistors take a bit of effort... try mouser.com.

cool.gif assembly - nope, was made in factory
c) the new schematic - most likely, when passing over the schematic in PDF to a real schematic in protel, i may have mis-connected some wire.


Anyone else built this unit and works ?

Since the 4383 is only available in a surface mount package, I found a company that sells surface mount to through-hole adapters.

I am looking for an updated schematic if anyone has one, i heard something about some corrections made to it if that is true. Also i am looking for a pcb layout cuz that would help, and maybe a parts list although that is not crucial as i can get them from the schematic.  Thanks, hope i can find the parts!

There is no resistor 23 or 26-29.  The "header 2" and "header 6" are 2 and 6 pin headers... I'm guessing ken gaspar used pin headers for connecting his design to the xbox avip.

Using the pin numberings from JaredC01's Guide...

VCC is pin 1.  on the advanced or HD a/v pack, this will connect to the middle of 3 pins on the optical audio out.

I don't know because I haven't actually built this thing yet, but 1080i should work...  the colors might be a little off (like it might be too dark or something).  The sync seperator will work for that resolution, though your monitor may or may not support the resolution.

Would the advice of someone else saying that adding another op amp (Max4383) may help compensate?  If so how may i implament this into the existing circuit?
