First a little backstory.....

What happens when all our CRT's die and when one is new to our hobby, and dont want to throw some 150 to 200 US Dollars after a +30 year old monitor?
We can always buy el'cheapo converters from China, however they are absolutely horrible. Then we can buy an OSSC or Retrotink at some 120 to 150 US Dollars including shipping. We can go even more expensive, and buy the ultimate called framemeister. Yet do the price justify fully what you get for the money? Well... Both yes and no, and depends on what you want in life.

Then there are this RGB-to-HDMI project out there. It is basically an adaptor, connected to an RaspberryPI-Zero and some freeware custom software on the SD card. The project is a work in progress, and is constantly being refined. Much like the TerribleFire series of Amiga accelerators. All open source.

A series of two video's have emerged on youtube, and it has already spunned an internal Amiga version. That is for standard Denise and then another adaptor for super Denise. (OCS a500 and ECS a500 machines).

The original project page is HERE Remember to read their WIKI
The two videoes are HERE (first video) and HERE (second video)
The Amiga Denise adaptor project is HERE

Now. What is this tread all about?
This tread is all about talk, regarding this RPI solution. What people's experience is with it and how they fine tune their adaptor. Or using the Amiga Denise adaptor. Talk about software updates to the project and everything else. Mostly it is about if people can recommend this solution and posting pictures of how they set it up, information on how to make special cables for the various systems. Possible posting screenshots of the picture quality. And so on, and so on...

I have a feeling that this will become the best solution for the money, as the SD-Card software matures. If it isn't already good enough to give the best bang for the bucks. Anyway. Feel free to post any findings and share experiences with this solution here in this tread.

I recieved the Amiga500/2000 RGBtoHDMI adaptor. I still need to recieve the RaspberryPI-Zero, that I have ordered.
Just wanted to let people know, how the Denise adaptor looks like.

I will give an update, once it is up and running on one of my OCS Amiga500's.

Installed, tested and works. (and made 4 videoes on my YouTube Channel
All I can say. This is an awesomme solution for the price of only 59 euro total including shipping.

Hi, good morning! 😀

Just watched the videos and I think it looks really good!
However, some part of me is a bit confused about all the processing power that goes into this task.
On the other hand, HDMI itself requires it, so it's okay.
A typical LCD has more computing power/through put than any vintage computer, after all.
Also, this solution could provide faithful simulation of, say, a spefic tube mask type, an amber/green monitor or a black/white TV in the future.

Thanks for sharing!

Sure there are a lot of computing power used, compared to old vintage computers. However that is something I really dont think about. The main thing, is that it is working. 😀

As far filthers and special stuff like scandoubler, then I really dont know yet. I have just recently gotten the adaptor in the mail, and the youtube videoes were made the same day I recieved the RaspberryPI Zero. However, there are a pinheader, that a push button can be connected to. If the button is pressed during power on, then it will force 60hz and not stock 50hz refresh.

During operation, a long press will enter the setup menu of the PI-Software, and short pres is for changing selection. I guess a long press in the menu, would be selecting the highlighted option. To be fair, then I have not tried it yet, so I am only passing on information that I have read in regards to the software menu.

Installed the adaptor in my 500-Desktop converted Amiga500 Revision 6a. Changed the picture from sharp to soft in the adaptor settings menu and are currently having it running through the DVI input of my Sony monitor. Using an HDMI to DVI cable. No problems, and the picture is so great with this setup. The best setup with this solution that I have tested so far. Although scan lines are not possible as of now, despite it being an option in the settings menu, then it is not working as of now in the latest beta version of the software. I might test the last official stable version, however the beta is working perfect and scrolling is super smooth. I am really impressed with this solution. On standard/default resolutions, this is even better than the IndivisionECS-V2 solution that I had previously on this machine. Absolutely no ghosting anymore, and for only 59 Euro total (included shipping) compared to the IndivisionECS-V2's pricetag of 99 Euro excluded shipping, then this is a solid solution for people.

I made a new video for YouTube, with the adaptor installed in my Amiga500-DesktopCase conversion machine, explaining and giving answers to a few important questions that I have recieved about the adaptor......

Uploading as of now.

EDIT:
Again... Sorry about my inferior English. I only speak English on my YouTube channel.
