This is such a simple hack. It's basically equivalent to the classroom transparency overhead projectors of the past. You could 3d print a similar device with a USB webcam and a proper mirror for pennies. Is there a market for this?
- bryanrasmussen 6y agoYes, there is a market for things that do this - it's the projector market, so if people don't have the money to enter the projector market they use hacks like this one - examples https://hackaday.com/2014/03/13/make-an-hd-projector-for-next-to-nothing/ https://hackaday.com/2014/03/13/make-an-hd-projector-for-nex... https://www.instructables.com/id/Convert-a-40-years-old-DIA-slide-projector-to-a-De/ https://www.instructables.com/id/Convert-a-40-years-old-DIA-... first couple of hits for me when googling "convert old olverhead projector" So market wise maybe there is a hacky way that allows you to get a cheap reasonably efficient projector thaat would make these hacks irrelevant, without naturally pushing to solve the problems of the projector market and thus pushing the product to have a projector type price. I certainly wish I could think up something that fell in that niche.
