I'm a bit confused by this.It looks like you use the pots to drive the video signals straight to GND, this is bad(tm), as you're adjusting the level by loading the game - set it up as a voltage divider instead.
I am using it as a divider, not a variable resistor?Sorry for coming on a bit strong, If you use the pot as a divider and not a variable resistor, I don't think you will damage the board - load should be 1K regardless?
Edit: input on the THS is probably super high impedance, so load would be between 1K and ~0. I would imagine this would make the adjustments a bit jumpy.
I still don't really understand.Don't forget that the signals need to return, so load is not constant at all. You can probably Imagine the THS being 1MOhm resistor to gnd..
SIGNAL -----> R1 ------> R2 ----> GND | | THS(1Mohm)
They are already pretty thicc. More vias is a fair point. Can't hurt, so I'll add that on later revisions (I have a lot of other changes in routing made already).I'd make the power traces wider and add multiple vias.
Just feeding the raw composite sync signal instead?This looks awesome! I have a v0.1 Betsu Betsu (made by evilsim) which I'm using with my Combo AV EX++ control box (which doesn't do RGB attenuation) and OSSC - works great!
One addition that would be really useful for me would be a switch to disable the sync attenuation. If I understand things right, that would allow a Taito F3 to be used with an (unmodded) OSSC via the AV3 input. Is that possible / does it make sense?
