You recognize these massive metallic tins that your grandma makes use of to retailer stitching needles and random unidentified screws? A few of them really include cookies. However opening the tin to get on the sugary morsels is a ache within the fingers. To make his vacation gingerbread feasting extra accessible, The Skjegg constructed this cookie launcher.
That is precisely what it feels like: a contraption for launching cookies skyward, the place hungry folks can snatch them with out prying the lid off the tin. The launch triggers with a voice command for easy cookie consumption. And in a pinch, it may most likely be used to distract prowling polar bears.
The Skjegg hid all the working bits contained in the tin, so that appears largely regular for those who ignore the trapdoor on high. The working bits embody a radial journal mechanism, which drops the following preloaded cookie into the catapult. The catapult is spring-loaded, with a DC motor to retract the spring. One other DC motor rotates the journal utilizing an optical sensor for positional encoding and a servo motor opens the entice door.
That every one operates underneath the management of a Seeed Studio XIAO SAMD21 improvement board, with a DFRobot Gravity Voice Recognition Module for the voice management. Sadly, the module The Skjegg had appeared to have some type of bug that brought about it to fail after some time. So, he additionally added a button for emergency cookie conditions.
Now The Skjegg can command an incoming cookie volley at any time when he feels peckish this vacation season.
