Great idea!My own birds don't fly out. I actually leave the door wide open when changing their water dishes and they stay inside. Plus it is a huge aviary so it would be pretty tough for them to fly out when I am coming and going. Even if they did they don't fly very far. I carry mine around the house on my shoulder and they will fly from my shoulder back to the aviary sometimes. Once they got out of my outside aviary went somebody didn't latch the door. When I went outside they immediately flew to my shoulder. They aren't really prisoners around my place. The aviary is their home and they don't mind being in it. If it was a small aviary or a cage perhaps they wouldn't be as happy to stay in it as much.

Going on 8 years now since I built this and my two parrots are still happy and healthy and the vet says they have no heavy metals in their system. So you are just plain wrong my friend. They do not chew on the wire at all. They happily chew on the wood frame, they chew on boxes, chew toys, millet, and their ropes. They don't chew on the wire. Ever. I think you are just accustomed to smaller cages and smaller aviaries where the wings are clipped and there is nothing for them to do. My birds fly around, play together (a green-cheeked and a sun conure who are best buddies and even snuggle together at night - I bet your parrot books claim that doesn't happen either) People have used galvanized steel chicken coops since 1844. The chickens don't gnaw at the wire -- and neither do my conures.

Worked great for my DS1104Z-S scope. I used the DSFR option.

Sorry, I will fix it when I get a chance. Here is the new link:http://www.atmel.com/images/Atmel-0856-AVR-Instruction-Set-Manual.pdf

Point taken. I think I might do an experiment to see how much power is required to fry the battery.

I will do an experiment and see how much power it will take.

:) First, the total energy stored in this tiny battery is practically infinitesimal. It powers an LED. So it won't start any fires by shorting it. It won't even get hot. Next, it is charged with a current limited usb port, so no 'exploding battery' youtube videos are going to be made here.

That would be fun!

Nice Work!!

Love it!

The best thing about this is it helps stop the huge amount of styrofoam that we are dumping into landfills in the form of packing peanuts. Now that delivery times even across the nation are very short I don't think anyone need worry about rodents, other animals, or anything else. Great instructable! I will be using this every time I would have used packing peanuts.

This makes me very happy!

I am still in North Dakota but my "real" job is a Professor of Engineering and so it doesn't leave me a heck of a lot of time to start something like that. However, I suppose if there were only a limited number people who wanted them I could certainly build a few of them.

Often computer science types forget how they learned it and start to point fingers and dwell on minutiae with noses in the air. Much like an English teacher might complain about your grammar. Shouting "fire!" may not be a grammatically precise sentence, but it works, and it is much easier to teach to someone just starting to learn the language. They can learn the finer details of grammar later in my view.

Or even better, finish reading this instructable since that is what the whole thing is about. It explains, step-by-step, what that code does. Line-by-line.

Look up how the interrupts work. In particular the timer overflow interrupt. The main program loop just goes around and around unless there is an interrupt, in which case the preamble at the top of the program tells the program counter where to go in the case of any of a number of interrupts. When the timer overflows, the interrupt tells the program counter to go to the overflow label. Then it executes what is inside there and at the end it hits a reti command, meaning `return from interrupt' and it goes back to where it was when the interrupt occurred and continues merrily along, looping the main loop, until another interrupt happens.

Please read the other comments. We discuss this.

In reply to private emails I have received I wanted to mention this:You will hear comments all over the place from some bird "experts" saying that galvanized steel will kill your bird. I disagree. My birds don't chew on the wire and therefore do not ingest the zinc oxide. They use the wire all the time with their beaks and claws during climbing but you have to recall that birds don't use saliva in the same way that we do. For them the digestion is done in the stomach to a larger extent. So they would have to actually bite off and swallow the metal to be poisoned by it. They have plenty of things to bite and play with in the aviary and so ignore the wire.I have had parrots in my galvanized steel aviary for almost 6 years and my birds are just fine.

They fly around, land on my shoulder and snuggle when I enter the aviary, taunt the cats who sit around the outside and watch them, play with cardboard boxes and paper grocery bags that I scatter around the floor and listen to the music that I have playing for them in the background. In the summer I have a summer aviary outside on the porch which I put them in every morning so they can be outside and talk to passers by. They love it.You can make the decision for yourself, but I would never go back to putting them in a tiny cage with clipped wings so they are forced to sit on a perch and stare at the room all day. Mine love taking baths in their huge water dishes and flying around. They have lived happily together in the same aviary and they even snuggle together in their bed at night even though they are two different species of conure. My birds are happy and healthy and have a vastly higher standard of living than most birds I come across.

I only made one for myself. Here in North Dakota.

Beautiful idea!

My point is that the stack pointer initialization is not why your code doesn't work.Please go to step 9 of tutorial 7 and read it. That is where we introduce stack pointer initialization since that is the first time we need it.If you are not actually working through these tutorials step-by-step in order to learn command line AVR assembler then, yes, you should go back to using a studio.

Yes. Now I have been looking around and apparently some avr controllers are not initializing stack pointer on powerup as the datasheet guarantees that they should. Here is an interesting discussion of the issue:http://www.avrfreaks.net/forum/stack-setup-avr-asm

Volodya, so you are saying that nothing worked, then you added code to initialize the stack pointer and now everything works perfectly? :) Sorry, but I promise that isn't your problem.My point is that stack pointer initialization is not why your code isn't working.Please go to tutorial 7, step 9, and read it.That is where we introduce stack pointer initialization because that is the first time it is needed.

Thanks!! I am happy that there are et least a few people out there that want to get down into the fun stuff.
