One review on why people think they can make one... ( up to the person I reckon .. if you can make one that works for you .. then good )
Is this just a flashlight with holes poked in it?
Over the years, a number of customers have commented that this is simply a cheap flashlight with holes poked in it, implying that this would be something easy to replicate at a much lower cost. While this is indeed a cheap flashlight, the value of this item is not in the flashlight but in the pinhole mask in which the precision pinholes are 0.05 - 0.25mm in diameter. You cannot simply take a pin and poke holes in a substrate to get anything remotely this small and accurate. We once had a US supplier provide us with a quote for the pinhole mask provided in this artificial star. Their quoted price was $80 for each single mask!
Maybe it would be better for me to purchase one and be done with it ...!!
