Do you intend let the end user set stuff via an Arduino sketch, or perhaps consider a settings file like YAML/JSON, or even use an ESP8266 for web GUI/remote?
That AD chip can slice out CC - which would be nice to overlay on a scaled output to get rid of the jaggies, a TBC, and tons of other goodies to tinker with.
Metal box of course! Us tinkerers can probably come up with a 3D-printed enclosure or use a laser cut plexiglas sandwich if we need to access the pin headers.
Absolutely will be providing a commented sketch for the arduino where the important functions are noted and their default values.
Yes, the ADV will slice out CC but there is currently no hardware implementation to conveniently read and overlay the sliced data. FPGA IP is available for text overlay and scaling, but the cost is pretty outrageous.
One way I have considered is reading the data and sending it out as ASCII on RS232 to a Lumagen. I might actually give this a try just to see if its even a workable solution.
I do have some ambition to get a LCD display going and IR remote to adjust the 3D Comb filter settings, TBC enable, and interlaced to progressive conversion.
I had initially started out with an STM8 microcontroller but failed to get it working. The development environment(s) for STM8 is not geared toward tinkerers. I couldn't get i²c code to compile without any errors, arduino just worked. After using the arduino environment it became very clear that it was a decent solution to use because of the simplicity of downloading the program, loading/editing the sketch and uploading, and COST!
Web GUI has been on the list of things to include in a more fully featured box that handles component video, digital audio and possibly AC-3 RF demodulation.
Right now the goal is to get a 3 RCA to HDMI converter ready that allows users of the cheap adapters to experience what owners of the Lumagen 2124/44 rave about in a similarly sized package.
Sure, the Kramer VP-77x processors are available but they have some very strange quirks with audio muting and video motion detection. They also only do 480p. 480i is available as an output resolution but it is a reinterlaced output.
