Katy’s Final Project

This project was influenced by the increase in people working from home due to the pandemic. It is meant to signal that the workday is over and that you can now relax and unwind. With this tutorial, I will be taking you through the steps so that you can also make your own personal cocktail shaker that will turn on exactly at 5 pm, using a nodemcu. This project was inspired by the Crickit Shaker and utilizes the stl files from the Ruiz Brothers.

Through this project, I learned that an important step of any project is thorough planning. During the final assembly, I had to make many adjustments such as making a new button hole and using the previous hole for the power cord. Being able to fit the top on was also another challenge since I had not anticipated the new circuit assembly, I finally able to fit it on by clipping off some parts. I also learned how to video editing through shooting the video that promoted the product. 

In the future, I would like to incorporate more color into the project. Since I didn’t have the facilities to spray paint this project, I didn’t want to risk the uneven paint job that would result with acrylic paints.

Locked: final project

Parts List:


Locked is a device that measures the distance from a sensor to the locked position of a deadbolt and informs you if your door is secured. It is a cheap and fast way to set up a customizable lock detection system to old doors and buildings.

Katy’s Progress

Progress shot

1. Circuit Progress

Pictured above is the progress I made on my circuit diagram. Although this works through Tinkercad, I will need to add a motor driver to the next version of this.

2. Form progress

I am utilizing stl files from the Ruiz Brothers. I changed the box enclosure to fit the parts I got such as the illuminated button and patched up some other holes. I am currently in the midst of talking to two different people for printing, the vfl and another person.

3. Storyboard Description

The scene starts on the profile of a woman at her computer. She is typing and she starts reaching for her coffee mug, promptly knocking it over and creating a mess. The camera will follow her for more scenes where she gets food on herself, etc. Her frustration with the day becomes more evident until she looks over at the clock on the wall and she realizes its almost five. The look on her face changes from frustration to contentment and she heads to the kitchen. The camera zooms in on the profile of the shaker. It turns on now that is 5pm and the woman touches the button to turn it off. She grabs her drink, relaxes, and exclaims an audible ahhh. The last shot will be of her setting a glass into the shaker for tomorrow.

More IoT & Final Project Planning:

Final Project: a container that will lock your phone if you want to take a break from screen time or when you are studying to not get distracted. A text will be sent if the glass lock is open.

Number Light

The Number Light is a box with lights and a sensor that lets you know when someone is 1 foot away from your door. The number will be cut out of the main box frame. Behind it, will be a completely white compartment to disperse the light from the NeoPixel strip. A white canvas will be glued onto the cutout for smooth light distribution. Behind the LEDs will be the battery holder. The sliding side of the holder will face the back for easy battery change. The whole box will slide on two mountable sliding tracks.

This was a really hard project for me. As you can see from the video, I was not able to use a gemma, so I ended up using the arduino. Below you can see my tinkercad circuit.


The Petal Pusher

The final piece

I made a sunflower because I wanted a cute costume that utilized the zoom window, used old materials, and was something that I could then hang on my wall. This is a headpiece that will be converted into wall art. This project became more and more complicated as it was being made. The snaps were the most challenging part just because there are so many of them, but they work great. Originally I had intended to hot glue the petals onto the band but then I realized I needed to be able to move them around. For the improved version, I would tighten the elastic, I had left some room thinking I would need the space. but now with the weight of the stuffing and lights, it needs to be positioned further. Also, I would not attempt to incorporate 8 LED lights into a circle, it just gets too complicated and I would get a longer light strip. Through the process of making the petals, I learned that crinkling the petals could give more depth and that soldering directly to the micro controller gives a more stable connection.

I decided to take away the eight led lights since they weren’t working with the form and it also helped with the code as well.

For my code, I used buttoncycler since I liked the animations. To customize it, I changed the beginning colors to yellow, orange, and blue.

These are some of my process photos where you can see the evolution of the piece.

Tinkercad Circuit

My Halloween costume will have two circuits. The one viewed above will be sewn onto my cape. The lights will protrude the cape, and I will cap them with spiders. These LEDs will be orange, as the cape is black and purple.

The Gemma circuit is still a work in process. I will have the Gemma sewn onto the mini witch hat. I will use four 3V batteries, in a small carrier, a switch, and an LED strip. I am still working on the code, debating if I should just have the Gemma, or that along with the LED strip. I am excited about this project and how all the colors will come together.
