Im curious what the power draw of the 3.3v, 5v and 12v rails are on a naomi system underload. Im thinking of designing a jvs io board with power and Id like to get an idea how much headroom it actually needs. From what Ive read online, the naomi sun psu is probably at least double what the naomi...

Ive been working on my own supergun design for a few years and its finally coming together. I'm calling it the Winchester and the goal is to create a supergun that is compact and functional by itself. The features are: Component video encoding LM1881 sync cleaning THS7376 video...

Hey all, Im working on a supergun design that uses a teensy 4.1 microcontroller. I want the button presses to come from the teensy but the pins are not 5v tolerant. Would using a level shifter, transistor or an optocoupler make the most sense? Or something else entirely?

If I wanted to use a microcontroller like an arduino or a teensy for my jamma inputs, would I need a level shifter up +3.3v to +5v?

Hey all, I am in the process of designing a supergun and I was wondering if its worth it to add a LM1881 on the sync signal? Or is it only used when you want to strip the sync signal from a video signal?

Im designing a supergun that uses the CXA2075 for composite and I want to use the THS7374 amp. Does anyone know if I need to use a pullup or pulldown resistor when connecting the CXA2075 composite out to the THS7374 CVBS Input pin?
