An air to air heat pump struggling at -15 deg C air temperature, the efficiency is getting low with all the ice building up on the heatsink that has to be melted every 30-60 minutes. It is still able to save some electricity.

"photo diode? LED? IR LED? solor cell in epoxie? photoresistor?" Nope, nope, nope, nope, and nope. You are close. I will give you guys a clue. There has to be a reason why I put it in the cool pic thread.

Is it a photodiode casting its shadow on the plume of smoke eminating from the explosion of your breadboard in the background? (the explosion being why the photodiode is flying through the air?)
Or maybe an ultrasound of your left lung after your wife/girlfriend walked into the garage during "playtime" and told you that you were going to be a daddy
Or how about a photodiode being used as a spaceship prop (seen here entering Earth's atmosphere) in an ultra-"B" flick shot using your Fisher Price PXL-2000 video camera? (frame grab gotten by taking a picture of your TV screen during pause using your cell phone's 500-kilopixel CCD and JPEG'ed for minimum size, hence the spectral quantization artifacts)
Sigh...ok...enough with the outlandish suggestions. Maybe it's just a some radiotelescopy of a nebula that looks remarkably *like* one of the above
