I'm am starting a project where I would like to be able to project an image(a QR code, 2D Barcode) from a small handheld device. Preferably flashlight sized, maybe a bit larger and I'm trying to collect ideas. It doesn't have to be any thing awesome, just be able to project the QR code onto a surface (not far away) and the QR code be able to be read by a scanner/reader. I am thinking about trying to make something using a piece of transparency film with the code printed on it and a light source behind it, but I was wanting to see if any one else had any ideas or input on my current idea. Thanks.
