      @tjohnson The idea is indeed the same as Gert -- the ICs are amplifiers are for mixing the RGB -> Component. Also there's a voltage regulator; I don't trust the PI to have clean outputs on the GPIOs.

      For the next gen, I was thinking of using a real triple video DAC but it looks like they're quite pricey. A R2R ladder would be better though, the problem with the current design is the need for binary scaled resistors which are also hard to find over a range of 8 decades.

        @IcyFever Haha, thanks! If I ever get there you'll be the first to know! Yeah, I really lucked out - found one on Craigslist yesterday for $30. I didn't even know about the FV310 until you mentioned it. I used to have an older WEGA but the FV310 really surprised me on how sharp it was.

          Hi Guys,

          Here's an update. Thanks again for all your help and kind comments! I figured out all the scaling issues and everything works nicely. I'm as happy as a cat :)

          Also designed generation 2:

          It should solve the noise problems, be easier to build and adds a NTSC encoder for S-Video and composite outputs!

              @mikechi2 not sure why i never saw this thread. I am very much i terested. As long as i dont have to do any programming i am ok with assembling it myself if it makes it easier for you. I have been obsessing about going crt lately. Since you mentioned a scope, i also decided to build a circuit to use one of my scopes as a tv. Just because i can. :)

                Thanks guys :) The next gen is done. It adds S-Video (which looks awesome and really makes it compatible with most higher end TVs) as well as composite (which is crap):

                Still need to shoot down some bugs. In the meantime, I might also suggest checking this out to get your 240p (via composite) fix:

                Will keep you posted!

                  @mikechi2 im going to need to buy some some video cables for my pi-station 1. I have the original video port still for composite. Now i am going to have to wire s-video and component to it as well. :) 😊

                      @mikechi2 can you post what settings we need to set/add in the config.txt or anything else we need to change to get this to output video?

                        @edmaul69 Good question. Argh, I don't have permission to upload a file. I'll post detailed instructions on the website this weekend along with some notes about how I'm configuring my emulator settings and get back to you ASAP!
