Turbo/PCE/Genesis/SNES RGB to Component Video (YPbPr) Mod Chip Now For Sale!!!

Going off topic - is there an easy way to take 5 volts and bump it up to say 9-12 volts?

The reason I'm asking is that Euro SCART TV's have an automatic switching mode in the Scart socket that changes the aspect ratio between 16:9 and 4:3 depending on the voltage presented to pin 8.

Currently I have the 5 volt line from the DIN going here, so it's switching to 16:9 everytime I power on. Could a simple transistor circuit do this?

You can try a voltage divider circuit to increase the voltage.

Thesteve confirm this will work on the nesrgb mod.

Don't know what you mean?

don't wire this pin on SCART and you'll have no trouble.

Yeah, very easy, tap a power contact after the power switch (best point), anywhere before the power line gets to the 5 V regulators! The power supply is rated 10 V, but it's a cheap unregulated design, and for me, it measures like 11.9 Volts, so no power inverting is necessary! I assume we're talking about a Turbo Duo console, but many others are at 10+ V as well.

Something tells me pnauts is right though, you never should've connected 5 V to this pin in the first place... It should just default to 4:3 with the video signals connected. Nobody else ever had this problem or talked about it (in my time here) and you shouldn't have to wire a 12 V line in a cable just to get a default video signal working. Regardless, I offer the solution with the assumption that you possibly have a picky TV that does it by the book when it comes to the SCART standard.

I'm currently working with thesteve on a totally redesigned new component video board.  The new boards will be better compatible with more TV's sets and will have a more universal application usage meaning it will work with more systems not just with the turbo/pce systems.  More to come.

Very cool!
The video qualitys improvement is amazing, over it's already good look.

Here is what the new board layout looks like with an optional composite sync stripper board.  I will do a final review this weekend.

[crans]

We will all be looking forward to your finding's.

Orders for the new revised boards and parts have been placed.  They should arrive in two to three weeks.

[turbokon]

RGB to Component version 2 boards are ready for sale.   Still waiting on parts for the sync stripper circuit.  The sync stripper circuit is not needed for the turbo and pce systems.  Note the main board will be slightly more then the previous version due to more components with the revised design.  New price is $37 shipped within US and the sync stripper will be optional available for another $8.


Some improvement over the previous version:
The signals are more stable with more HDTV that supports 240P (better sync)
higher clarity
better black level
better green purity
more consistent brightness over different sources and displays
higher contrast range (adjustable)
Better ground shielding to protect from interference
Reduce jailbars

I have not updated my website yet, so please pm me for ordering.

Do these add any additional latency to video output?  Have you checked?

[thesteve]

they cant as they dont buffer
all transcoding is done realtime
