I wish the author included a BOM with links to the parts needed.

Set up a Raspberry Pi meteor detector

Re: Set up a Raspberry Pi meteor detector
#22I'd be inclined to get a POE hub/switch cheap (30$ branded, unbranded and talking sub $10) and the adapter for the Rpi and run them both over that. Not sure how the cost balances for this and maybe a bit more going that option, but if you add a single other POE device, it would definitely pay off cheaper and certainly more flexible cable wise on Ethernet and as such power.
That's the same type of setup that is common for security cameras using PoE. It seems to work well. Depending on how resource intensive the video analysis is, you could have several cameras being analyzed by a single mini computer (Atom based $100). That might be slightly cheaper than a single Pi per camera.
Also, where are you finding those PoE switches?! I was looking for 8 port ones just a few months ago and they were about $50 for cheap ones and at least $80 for brand names.

#23I imagine this would capture meteor flares only in areas with minimal lighting. In urban (and surrounding) areas, the light pollution would render human (and I imagine, digital) eyes blind to the celestial tapestry. Are there cameras that can filter the light pollution out?
Could possibly capture the ultra red (heat) range that are usually filtered out by normal cameras.

There are filters[0] you can add to lenses that will filter out certain types of lights. While it will never replace finding an actual dark sky location, it will slightly improve what can be imaged.

#25Do you know if this would work over wifi assuming you power the Pi and camera via some other means?

I would very much like to know too. I would love to get some PoE equipment.

Amazon Warehouse was the best deal I found a few months ago.

#28I was kind of imagining this would use an sdr to look for meteor scatter from distant VHF transmitters (https://en.m.wikipedia.org/wiki/Meteor_burst_communications)

#29I've always dreamed of capturing good footage of UFOs, fully knowing that they are with 99,99...% likelihood just fiction.
The latest round of UFO buzz got me interested in how one would setup tracking network for UFOs, this might be an interesting starting point.

#30Technically, every server I run is an extremely localized meteor detector. The rate of false positives is horrendous, though…
