Started my automatic feeder project

All,
In case anyone is interested I have started to post about an automatic feeder that I am building. I completed the food housing and a first round of testing today. It is very rough, very much a work in progress. Rather than post everything in multiple spots, here is a link to it on my website:
Aquarium Feeder Project
Since I have not bothered to put a forum/comment section on my website yet (and may never) I will gladly take constructive criticism/feedback/ideas here. Please keep in mind this is just the start of it all...

Well (Mike?), this looks great.
I can't set up a smart TV so you've completely boggled my mind!

Actually it is not too bad so far. I did not have to do much to the Arduino sketch that I based mine off of. The time consuming part was designing the housing(s). The whole thing should be cheaper once I have it a bit more finished. At that point I will be able to stop using an Arduino UNO and switch over to just using a basic atmega328 with just a few components. That is driving up the cost ~$20 in my estimate.

I had one person wondering how it worked a bit so I will try to give a bit more explanation about the rotation. Think of the face of the housing as a clock. The opening sits on the side of it at ~2 to begin with. The scoop starts at the bottom of the opening and curves up a little ways. When the Arduino starts up the opening rotates clockwise until it gets to ~8. That means the opening has already passed by the bottom, dumping what little food might have been in it. As it passes by that the scoop will collect some more food. Then the servo changes direction and the housing rotates counter-clockwise back to 2. This dumps out the food that got collected.

P.S.- It's Dave.

Oh Dave! (Sorry it's been awhile!)

You might be onto something with your design.
Feeders are one piece of equipment that definitely need improvement on!

No problem. I was "out" for a while and on the best of times I do not post a lot.

I hope it proves useful. I really like the idea of having it somewhat modular. I really wish Neptune Systems opened up the AquaBus so this could be better integrated but at the same time this allows more people to use it. The Apex is powerful and useful... But there are some things about it that always bug me.
