Two day, 4 hour making a prototype, 3 hours for this, and 2 hour debugging

It's a very precise and sensitive machine, I found BRAY's live time is 30 frames during this. It won't work even if there's only a single frame delay.
Original one have a resolution of 12x12, but during debugging I found 3 pixel can't be sent properly because of the travel speed of spark, only 2 frames late. But I have to reduced the resolution to 12x11. Seems the biggest resolution without issues

Even now we have 99 channels in 44.7, I can't make it bigger due to the current speed
