It only rains here maybe 7 or 8 times a year and an event when rains (funny to meet your neighbor after 5 years when he comes out front to look at the rain), hee hee.
So these in backyard are rare also……
No matter how long I live somewhere else, the rain always fascinates me. I grew up in the high desert of California, and similarly, we probably saw around half a dozen days of rain a year. It must rain 50-60 days a year here in Maine, but somehow it never loses its appeal. Can't wait for this weekend's snow! I'll have to get some good pictures and post them here, if it happens.

the device is optical (fairly obvious), but it is not a camera - and don't spoil it chris, since you already know... and I don't mind losing one of the [insert number] parallel running boards, as I plan to use only one, and maybe eventually the second, so far...

The last two are some pictures of the entire assembly from which my "larger" contribution to the junk box will come (being symmetric, independent board design, the rest of it will function hint) and take a guess what it is! - I posted one of the chips to help you out
Is it the optical modulation and beam combiner block out of a 3 chip DLP projector? I notice soldered/welded alignment thingies on each unit, and Peltier devices to presumably keep the DMD chips cool.

that's right! it is from a NEC SX-10000 tri-chip DLP projector (the assembly in question is known as a "Light Engine" I won't be throwing optics into the box due to their size, but the board and chip (laid flat, and only one of the three) should not have a problem fitting in... the projector was HD, at 1080i
I snagged this light engine from a local repair place: the apparent issue was that the optical compound on the chip got contaminated or something, anyway it causes the color palatte to shift over to a magenta like hue... otherwise it is supposed to work fine
To the Recipient: I challenge thee to make the DLP/DMD (however you will refer to it) and make it work on it's own, after making the included driver board work I will still have the other two boards for the future.
