Composite Out through TV Module
Much better:
VGA Out
After Composite wouldn’t work, I knew that I needed to get RGsB to the BMBT monitor. My first direction was to go through a HDMI->VGA converter. However, I later learned that many of these converters just work on a fixed set of input VGA resolutions, and that I needed a special resolution for the BMBT (more on that in a bit)
HDMI to VGA Video Path
VGA Resistor Ladder Path
VGA_Zero
I bought a VGA_Zero from eBay and soldered up the 40pin connector. It was the first time I soldered up anything that small to a PCB.
Altinex VGA to RGsB Converter
Next, I used an an Altinex VGA->RGsB box
I mounted the Alintex Box to the test bench with some Vinyl Siding J-Trim.
VGA Video Timing
This was probably the hardest part of the whole project.
Quick-Switch Relays
I wired in a set of relays to allow swapping the video source mid-frame
I needed to get high quality vidoe out
Source Timing
PowerStrip Timing
