This device allows the dog to let us know when he is out of water, by alerting us with a sound and light. If we are out of the room and don't hear the tune, the light stays on until it is reset so we can see it as we walk by the kitchen/utility room and know Cody (our dog) has pushed the "button". Cody already has a push button to let us know when to let him outside, but he uses that one with his paw. I wanted him to be able to push this with his nose (he already knows the command for that, so I figured it would be as easy to teach him how to use this device as it was to teach him how to use the other one, which he learned in just a couple of days).
In true Instructables fashion, this device uses hacked and scrounged materials and a few tools. Please read through the instructions and you'll have a better idea of what types of materials you can use that you have on hand. Your device may vary in size and construction depending on the size of your pet and your personal preferences.
The two primary components are a poster sound recording device and one LED tea light with push button activation.
You will also need;
- tracing paper
- paper & pencil
- "hobby wood" scraps. I'm using left over pieces of Midwest products 1/8" and 1/16" basswood sheets and birch plywood sheets and 1/8" & 1/4" basswood strips of the type usually found in craft stores, and 1/16" hardboard.
- one or two hinges that swing freely
- cardboard - "regular" 1/8" corrugated cardboard box type, and thin cardboard or card stock (a cereal box or shirt/gift box will be fine)
- clear plastic - 2 pieces approximately 3" x 5". You can upcycle this from plastic food containers, it doesn't need to be sturdy.
- aluminum foil
- acrylic paint in whatever colors you choose
- sandpaper & files
- square rule
- soldering iron, solder, wire suitable for electronic components, wire nippers, shrink tubing
- masking tape and double-stick tape
- wood glue and white glue
- hot glue gun and glue sticks
- blocks with straight sides - I used legos, but you could also use a small box or other blocks.
- jeweler's saw (fret saw or scroll saw)
