count me in for a Kit if possible as well!
I would take a pre-built or kit.
I’d be down for a prebuilt module!
I’d take a PCB + panel too, love the mock up :]
If you or someone else will be doing a built module I would be interested.
I could do a built module won’t be difficult, but keep in mind that you will need to mod your Visual Cortex, which is solder a 2x3 pin header.
Its not difficult but you will need to do it your self (or find someone close to you)
Yeah I’d be down for a prebuilt, Sure I could figure out fitting the header.
Hey, could a little header kit be sold w the modules? That would make things so easy!
the full kit im planning will have pcb panel, pots, knobs, jacks, components (ics, resistors caps etc) a 3x2 header for cortex and a ribbon cable for the rgb expander header.
@creatorlars Im gonna do a second flavor of the expansion with YUV outs. Was wondering if I can use the Lumma circuit that you kindly show me as the Y
or I must do another new lumma signal (I was going to go with voltage dividers of R G and B)
Y = 0.299R + 0.587G + 0.114B
My real question is if the Lumma of the YUV is different to the Luma schematic. Luma YUV vs Luma RGB (I would say no, but I’m in doubt.).
This lumma circuit is magix!
Great work on this @luix! I’m down for two kits. Curious as you’re planning a second breakout … could they easily be combined into one expander?
yeah should be easy to chain them.
@luix That circuit should work fine! For the U and V outputs you can follow a similar method. I generally use SPICE simulations to tweak circuits like this until output voltage readings are correct according to RGB input voltages. 5Spice has a free version we’ve used for years, although I’m using Tina more frequently now.
I’d be down for a kit to support the project. My cortex already has expansion headers soldered
I’ll probably want a PCB+panel at least. Wasn’t planning on getting a visual cortex, but I’ve run into a dead end trying to troubleshoot my cadet sync generator build–so I should probably just buy a vc.
Sign me up for one too!
I’ve been running the VC component output back into its Input Decoder, and then out from those 1v RGB outputs into the MemPal. Not so ideal, of course, as I lose that component input. :-/
I’d like to get a kit or prebuilt as well. This is a great project, thanks!
Def. in for a panel/pcb when you are ready to take orders
I am in for this! Would take a kit, or panel/PCB, or built version.
