@foone you can still do that if you want to bang out prototypes fast! or if you just find it cool to make your own pcbs
i do find it pretty cool and what i recently came up with is to use a dlp projector with the color wheel removed and a high-power uv led instead of the lamp, a'la photolithography
i found a cheap 1024x768 dlp projector and i calculated that if i focus that to an area of 81.92x61.44mm i should get 0.08mm pixels which is pretty neat (for comparison a tqfp144's leg is ~0.22mm wide) but we'll see how that goes lol
