Hi I already am subscribed to his channel for a while and I've already been watching all those videos you've linked :-) The problem is, that DMD chips from Texas Instruments are in general darn expensive, especially the ones which survive 329 nm light and don't die from overheating after a short while, or degenerate otherwise.

Hello List.

I found some video clips from a Dutch (ex Philips) Engineer who builds his own DIY maskless stepper :-)

Part 1: Optisc https://www.youtube.com/watch?v=_w0Z2Y5vaAQ Part 2: Mechanics https://www.youtube.com/watch?v=MdRwiI6VLmk Part 3: Electronics and Software https://www.youtube.com/watch?v=ebv_9cmLNqo

Part ?: Building a Small Cleanroom for Photolithography https://www.youtube.com/watch?v=bkmVmsMUsJU

I think all videos here are a great source of inspiration.
