    I came up with a soltion to an age old problem:

    Q: How can you keep pigions from stealing all the seed?

    Requirements:
    a. The pegions can't feed at the feeder.
    b. The pegions can't feed from the ground below the feeder, where feed is placed and
    little birds knock the feed to the ground.
    c. The little birds can still feed with no problems.

    This would be a good interviewing question to test ones ability to solve design and engineering problems. I will post the solution in a few hours, or if someone comes up the same or equaly plausable solution. Hint: I came up with the solution because my Father started going nutz and throwing rocks at the pegions. ~TheArch :-D

    put feeder on island in middle of pool with sharks with freekin' lasers coded to auto fire at pigeon shaped/sized birds ..ha, you call this a challenge...

      The larger birds have to go on a diet. No one likes a fat bird around here.

      I have seen that on a sign in a pub, "No Fat Birds".

        Buy a Time Machine Go back 50-100 thousand years and through DNA manipulation and selective breeding, stop the pigeons from evolving. Come Back to the Present. Feed Birds. Wanna Buy a time machine? I have one here, I only bought it next week.

          Haha, I actually thought of this minus the sharks and pond. I was going to use CUDA to do the pigeon shape detector, based on 3D exsisting object libs, and face recginion.

                Okay but you return to find out that you have accidently help the dianasuars to evolve into man eating super freaks. They become the dominate species on earth.

                    Hmmm a little trouble with your time perception there. I am talking about going back 50,000 years. The Dinosaurs went extinct 65,000,000 years ago.

                        Any job to be done correctly requires some research and study before implementing a solution. 0) Capture or kill a number of birds that are the approximate maximum weight of the birds you want to allow at the feeder. It would probably better to kill them outright since they'd be trying to fly away or pecking at your eyes, thus preventing you from completing the 2nd part of the study. 1) Establish a maximum average weight of said birds (you need to be able to put them onto a scale, that's why they should probably be dead). 2) Construct a bird feeder that has spring-mounted metal perch. at each end of the perch connect an electrical contact in such a way as to be a complete circuit which will kill birds that exceed the weight of your pre-determined maximum average weight. 3) To solve the bottom-feeder issue, you could also connect up our friend - the wire mesh and electrocute any animal that happens to walk on it. Of course, you'd probably be taking out squirrels, neighborhood cats, and maybe even yourself if you forget about the mesh when it's time to go refill the feeder. If you wanted to have some real fun, you could make it so that the mesh is only charged when there's a heavy bird on the perch...

                          And what, pray, is wrong with Diana's Uars? She had a fine Pair of Uars if I remember correctly.

                                PETA approved version: acheive 100% employment of pigeons in the carrier business provide them with corporate cantina stamp book sooooo easy.... not like the question i was once asked "how do i determine the weight of a 747" i said, "rtfm or just ask the pilot" where the 'out of the box' answer was to chop it up into small pieces and weigh it on a regular scale....boy, did i learn a lot that day *no hijacking/off topic intended

                                Opium is my business. The bridge mean more traffic. More traffic mean more money. More money mean more power. Speed is important in business. Time is money. You said opium was money. Money is Money. Well then, what is time again? icalburner.net

                                    Any job to be done correctly requires some research and study before implementing a solution. 0) Capture or kill a number of birds that are the approximate maximum weight of the birds you want to allow at the feeder. It would probably better to kill them outright since they'd be trying to fly away or pecking at your eyes, thus preventing you from completing the 2nd part of the study. 1) Establish a maximum average weight of said birds (you need to be able to put them onto a scale, that's why they should probably be dead). 2) Construct a bird feeder that has spring-mounted metal perch. at each end of the perch connect an electrical contact in such a way as to be a complete circuit which will kill birds that exceed the weight of your pre-determined maximum average weight. 3) To solve the bottom-feeder issue, you could also connect up our friend - the wire mesh and electrocute any animal that happens to walk on it. Of course, you'd probably be taking out squirrels, neighborhood cats, and maybe even yourself if you forget about the mesh when it's time to go refill the feeder. If you wanted to have some real fun, you could make it so that the mesh is only charged when there's a heavy bird on the perch...

                                        Well, you have a choice. 0) Create and dance naked around a ceremonial bonfire while singing songs of the hunt 1) See if your dog will eat them 2) Skin the squirrels and sew their hides together to create a shield to fend off stabbing weapons. You can use their skulls (and the birds' skulls as well) to create a ceremonial headdress or necklace for your lovely bride. 3) Squirrels and cats are good eatin'. Don't waste the meat. 4) You can mount the humans on pikes at the end of your driveway.

                                          PETA approved version: acheive 100% employment of pigeons in the carrier business provide them with corporate cantina stamp book sooooo easy.... not like the question i was once asked "how do i determine the weight of a 747" i said, "rtfm or just ask the pilot" where the 'out of the box' answer was to chop it up into small pieces and weigh it on a regular scale....boy, did i learn a lot that day *no hijacking/off topic intended

                                          Opium is my business. The bridge mean more traffic. More traffic mean more money. More money mean more power. Speed is important in business. Time is money. You said opium was money. Money is Money. Well then, what is time again? icalburner.net

                                          You figure out how many USAF Grunts it takes to lift the front wheel. No kidding, the when we did this inforn of the Russians they really freaked out, they thought Americans were super humans. :laugh: Actually you would ask the load master of the airplane, ot the head sturat in First Class.
