I found a semiconductor electronic piece called photodiode at Thorlabs Catalog , extremelly wide range powerful sensivity and 11 dollars.
If you attach a Analog Digital Concerter , an ─▒ntegrated circuit and a memory card , you can build your camera. But you take single pixel image.
I read some people is thinking to put a mylar mirror and move it and get full image in 10 seconds.
Any idea , how can We take full picture with single diode.
