99: Dog Toy

I have a mad urge to build an interactive amusement for the left-at-home dogs in my extended family. Yeah, I know other people have-done/are-doing this. So what.

I figure on implementing the following features using both a Raspberry Pi and an Arduino Nano.

Things I could provide:

1. Call to the dog -- recorded voice.

2. Show pictures or video clips of owner.

3. Play animal video clips: e.g., squirrels, lambs gamboling.

4. Dispense treats when dog touches proper button. (indicated by voice and LED)

5. React to the dog via motion detector.

6. Take video camera stills.

7. Via smartphone web page:

   - Turn the system on or off.

   - activate different "programs".

   - Keep track of treats supply.

   - Play back today's history of access.

   - Upload images (low-res, B/W) image from the camera.

Raspberry Pi system -- $100

Arduino Nano (control motor) -- $10

Video monitor/speaker -- $50

Stepper motor -- $10

2 Photosensors -- $2

PIR motion sensor -- $2
