I still haven't made the sample video signal because I have been scared to connect the arduino without fully understanding this composite EGA signal protocol. Also, I haven't been able to analyize my arduino to verify if it runs at 25K..
No worries once we get the signal board in we can start at 15Khz and work our way up to see what the highest level we can reach is.
Well we got the board and the cable converter hooked up a raspberry pi and tested out on a monitor we got the monitor to recieve the signal but when we had the arcade monitor on there was a loud pop from the back and the monitor flashed off. Now the monitor just clicks instead of powering on. sounds like a relay we can't see exactly where it coming from and the schematics haven't been much help. SOOOOOO we are going to have to get a TV to replace the monitor. I was looking on craigslist and there are some free ones we can look at or some good ones for under $40 We need one that has a power return feature so I will try to find one that lists that as a feature. Gonna need a ride to go pick up the TV whenever we find one though.
So the plan is to use a CRT TV rather than a LCD? If so, I have a large CRT TV in my garage that I can donate to the cause.
I don't know if it has the feature you require, but it is a flat tube and was higher resolution than a standard CRT before high-def was a thing.
I say bring it in and we can see if it will fit the cabinet.
Ok, when in the next weekend for the Arcade? I'll bring it, but it's a one way trip for the TV, if you don't need/want it, I'm not lugging it back, LOL.
yea just drop it off anytime. If it doesnt work it will be taken apart and repurposed for something else.
Well its been awhile and many changes have occurred. Instead of a full size arcade we are going for table top Arcade box that can send out a video signal to whatever we want. I purchased 2 more joysticks and the rest of the buttons so we have hardware for all 4 players now. We are installing everything into the old joystick box of the full size arcade. but we had to replace the MDF with a new board so we could install more buttons.The holes for the joysticks and buttons are drilled and will be installed once the lab reopens. The edge molding needs to be sized and a proper sized channel needs to be cut into the edge of the control top board. Need to measure the thickness of table saw blade to see if it can be used otherwise it can be cut with the pull saws that were donated.
To Do List:
Will meetup saturdays in between classes or meetup. if anyone else wishes to help out or discuss the project
