The SCART2DVI is an open-source (CERN OHLv2) device, designed for 15KHz (240p & 480i) retro gaming signals. The gerbers, as well as the Eagle design files can be downloaded here. These boards are tested and confirmed working: http://retrorgb.com/assets/dvi/SCART2DVIv1.1.zip
Insurrection Industries has made the SCART2DVI available for purchase. Please read this page and in the video capture section before purchasing…this is NOT a scaler!: https://insurrectionindustries.com/product/scart2dvi/
This device is powered by USB, passes through audio and has toggle switches for both the LPF and sync stripper. My advice is to start with both switches off and toggle as needed. I’d expect in most cases you’d need the sync stripper on. If you’re not sure if your console already has a LPF (such as something modded with a THS7314) then try toggling to see if it removes noise. More detailed information on how to use this adapter can be found here: http://www.retrorgb.com/datapathcapture.html
3D Printed Case
A 3D printed case will soon be available for the SCART2DVI. This will be available as a free, open-source 3D print file and also available to purchase.
DVI-I Cable / Connector
This device connects to your capture card via a DVI-I cable or coupler. Make sure whatever your connection is using has the analog pins, otherwise it won’t work!
Other Cables & Accessories
If you’re keeping the SCART2DVI close to your capture card for the least amount of signal loss, you’ll want some short cables. I also like to use a cable tie, to help with strain relief when a coupler is used:
Full Bill Of Materials
Here’s some component links, to try and make your ordering easier! As an FYI, all small components are SMD 0603.
Here’s an all-in-one BOM (without the SCART connector) that was provided based on the below links (personally untested) that might make ordering easier: https://www.digikey.com/short/pqr5z4
7x Capacitor 0.1uF (100nF): https://www.digikey.com/product-detail/en/CL10F104ZO8NNNC/1276-1258-1-ND/3889344/
Cheaper links, but either long or expensive shipping (better for 5 or more though!):
2x Screws (need to double check): https://www.digikey.com/product-detail/en/te-connectivity-amp-connectors/5207953-3/5207953-3-ND/1121976
Note: If audio is too quiet for you, replace the components in R7 & R8 with 0 Ohm resistors: https://www.digikey.com/product-detail/en/CRCW06030000Z0EAHP/541-0.0SBCT-ND/2222749/
I’d like to look into improving this device any way possible. The first thing on my list would be to have a switchable low-pass filter that can handle multiple frequencies for use across all analog resolutions (240p – 1080i). I’d also like to see a VGA version, but held off on making one until the filtering options were solved, as most VGA uses would be 480p and up.
People with the necessary knowledge are encouraged to edit and modify this as they find ways to improve or change the design.
Voultar has also prototyped a similar product with dual DVI + SCART output designed for streamers. No pricing and availability though.
