Science Buddies: "Ask an Expert"

Is there a way to block out the visable light spectrum and see things at infrared wavelengths at low cost

Hi dafender,

I found a few projects that seem to address what you're asking about:

as well as a starting point for more general resources:

If you have specific questions about what you read or building your own, let us know!
