Solution for external Flicker fixer?

[GWhizz]

I got my GBS 8220 and had it setup and running in a couple of hours including making a 23pin out of a 25 pin dsub connector. It works Great on most stuff some fast moving Pal games like Agony don't display too good screen does not update fast enough seems like. All in all a good cheap solution to replace our old 1084s.
By the way I am sourcing some 23 pin solder type dsubs if anybody is interested will take a couple of weeks before I have my hands on them but will list on forums when I do.

Hey guys I just blown the lastest GBS 8300 (Ver 4.0). I used a 5v 3A adapter and in a few secs smoke came from the SMD 470uH Inductor coil. I looked up the specs for the Inductor coil , and it's Maximum DC Current is 540 mA. Not even 1A, let alone 2A ARRRGG!!!!.. Now the board don't power up, so I bought a replacement. But it's not SMD (through hole) (Though I'll still be able to solder it in).. It's only handles 1A. Looking at the circuit, the power goes first through a 3A diode and then to the coil (In the pic).. Should the current drop before the 470uH Inductor coil???...

Hi all!

Any experience or comments about these RGB SCART to Component WITH RCA AUDIO Converters:

JS Technologies http://www.js-technology.com/store/product.php?id_product=14
or
ShinyBow http://www.shinybow.com.tw/pro/detail.php?pid=141&cid=79&f=57&pa=57

Thanks!

EDIT: My research seems to point to the JS Technologies unit for quality... Have you had any experience with this one @djos ?

EDIT: Purchased the JS Technologies unit so now just waiting for delivery and I will update with my experience!

Received the JS Technology RGB SCART to Component YUV convertor today and all I can say is: WOW!

The picture looks amazingly crisp and clear and the scrolling in games is smooth as! Runs absolute rings around the SCART to HDMI convertor (due to it's fuzzy de-interlacing which I just couldn't deal with)

I'm not sure if anyone can answer this but does an Amiga RGB port only output an interlaced signal or can it be progressive?

Hooray, another user that has confirmed the superiority of the YUV converter!

Amiga's can do interlaced and progressive output.

Pics or it didn't happen . Sounds like a great solution, but fairly expensive... What is the cheapest YUV solution that looks good?


-(e)

 

[djos]

Expensive?? They are about $40

 

[sweetlilmre]

Expensive?? They are about $40

The JST unit is: £99.00... Which is pretty expensive I'm guessing there are significantly cheaper ones on eBay?

[djos]

Lol, I hadn't seen that unit before - even the cheap units on eBay do a great job as they simply use a well known equation to convert RGB to YUV without scaling or messing with the picture.

 

[aZtOcKdOg]

Hi guys yes quite expensive but I wanted the audio from the SCART cable (for use with other units other than the Amiga) in one tidy box... I'd like to try the cheaper alternative one day too...

A quick pic or 2 sorry about reflection I'll get a close up shot later (but believe me when I say it's crisp, clean and smooth scrolling!)

lol it's proving harder to get a decent close up than I would have hoped! my camera phone doesn't capture what my eyes see that's for sure! Will dig out the DSLR and see if I can sync the shutter for a more accurate documentation of this for everyone...

EDIT: This photo turned out better than the others!

 

[sweetlilmre]

+1! Wow looks great!

Is there a way to generate scanlines from these YUV boxes for low res stuff like games and mega demos? A bit how the indivision AGA can do.

Not that I know of but here is an interesting read regarding the expensive options being tested with an Amiga:
http://www.videogameperfection.com/2012/06/28/xrgb-mini-framemeister-a-pal-torture-test/

I have also found that turning off the '100hz' mode and using '50hz' allowed for ULTRA silky smooth scrolling for things like text sine-scrollers in demos etc. It made a huge difference!

But sorry slightly off current topic of scanlines...

 

[Phipscube]

Yeah the xrgb mini is a dream, and don't worry, scanlines have come up in this thread before. I have made a custom box combining a gbs, slg3000 and sync seperator, but thats for vga, I was just wondering if the YUV boxes been talked about lately in the thread had such a feature.

The GBS need less than 500ma.
despite people continually claiming they need more current.

Found another great scandoubler solution.

Micomsoft XRGB2!


This is a old school scandoubler from the late 90's with JP21 rgb input on the front. It was really intended for japanese game consoles, however it supports anywhere between 50 and 60Hz.

The output by default is not frame locked, which means if the incoming signal is a 50Hz 15KHz signal, the output is 50 Hz 31KHz signal. Input 55Hz, output 55Hz. Same with 60.

So, that means you probably want to use it with a CRT for best results.

One thing that it does not do is flicker fix. So if you pump in interlaced video you will get out that typical bouncy, flickering associated with it. However, it still looks amazing.

Plus the unit has an option for enabling/disabling scanlines.

If anyone wants better quality photos, let me know and I'll post them up.

Doesn't this cost an arm, leg, eyeball and firstborn though? ☺

Yep

You can usually buy DVDO iScan VP30's new in a box for $250 aud or less for a used one and they have HDMI switching and high end 1080p scaling of analogue RGB etc sources!
