raspberry pi ir filter
Tonight at Reading Hackspace we spent a good hour or two dissecting the Raspberry Pi cameras and figured out how to remove the cameras IR filter, which makes it super fab for night time use with infrared LEDs, this opens up the opportunity to use it with security, wildlife and astronomy applications in mind.
Don’t try this at home, we did break a camera on our first go. We took both the lens and sensor apart and tested them to find the IR filter, it sits just above the CMOS sensor. it’s fairly easy to remove if you are very careful, very patient and have a good thin scalpel blade. Be incredibly careful and note all those normal H&S guidelines when using blades and also don’t take these instructions as gospel as there may be a better way!
The author obviously takes no responsibility for you trying this and recommends that you don’t! Thanks again to Barnaby who gave me a hand and really should get his own blog up nudge nudge!
