    <p>My project is an automatic cat food dispenser. The cat's food bowl is placed in a compartment protected by a lid. This compartment is attached via a power cable to a tower in the shape of a cat's head, which contains most of the electronics needed to operate the dispenser.</p>

    <p>The basic shapes for the tower and food compartment prototypes were created from existing templates on a <strong>laser-cut</strong> box generator website, <strong><a href="https://boxes.hackerspace-bamberg.de/" target="_blank">Festi</a></strong>. I modified these boxes according to the sizes and specifications I needed for my project by using <strong><a href="https://inkscape.org/" target="_blank">Inkscape</a></strong> and the laser cutter program, <strong>Gravostyle</strong>.</p>
