Overview of the battery and speakers inside the box. The image shows how the speakers and the battery were attached to the box. We attached the speakers to the box's front and back for a 360° audio performance. We fixed the battery to the box's interior to protect it from inclement weather and to avoid its movement.

Acoustic cues (e.g., vocalizations or 'calls' in wildlife) may effectively change social behavioral patterns in certain species. There are very few published papers on how to create a device at a low cost that can automatically reproduce acoustic cues to carry on wildlife playback experiments or management. We developed the Automated Call Box (ACB)...

... price. The total unit cost, which includes cables and equipment The photos show how we set up the ACB in the field during the experimental test and the overview of the system encased in the waterproof box. We placed the microcontrollers in the box tray. We attached the speakers to the front and back of the box (the battery is inside the bo; see Fig. 3). required to manufacture (e.g., soldering iron), is less than $190.00 USD per unit. Non-original brand purchase of materials could reduce cost but can lead to loss of quality and ...

... two jumper wires to the output side and two strips of electrical wire gauge (red for + and black for -) to the input side. It is necessary to use the soldering iron to attach the wires to the step-down (Fig. 5). 2. On the other side of the electrical wires, it is necessary to attach female connectors using the vinyl electrical insulating tape (Fig. 3). The female connectors will help to easily connect and disconnect the 12 V battery to the system. 3. Attach the step-down to the box tray using double-sided tape; the best place is next to the tray handle (Fig. 2). 4. Fix the Arduino board to the box tray through the tape included in the microcontroller base. Locate the Arduino in a ...

Then insert the speakers into the hole and fix them with stainless screws to finish the installation (Figs. 3 and 9). Connect the speakers to the Mp3 player's SPK1 and SPK2 pins by using the breadboard (Figs. 4 and ...

When we require to set the ACB in the field, we only need to plug the electrical wires from the output step-down to the 12 V battery (Fig. 3), and the device will be ready to ...
