# Xenomorph Halloween Candy Bucket ## Overview ![](https://cdn-learn.adafruit.com/assets/assets/000/081/554/medium800thumb/3d_printing_Untitled.2019-09-26_17_35_25.jpg?1569627746) Why roam around with a **boring pumpkin bucket** when you can lay eggs in warm human intestines collect delicious candy with a robotic Xenomorph head? This robotic candy bucket shoots out a small receptacle to retrieve candy and bring it back into the bucket. Some 3D printing is required to create the linear actuator. Two servo motors controlled by a Circuit Playground Express, coded with MakeCode, power this project.  ![](https://cdn-learn.adafruit.com/assets/assets/000/081/548/medium800thumb/3d_printing_IMG_7731.2019-09-27_18_33_09.jpg?1569623615) ![](https://cdn-learn.adafruit.com/assets/assets/000/081/452/medium800/3d_printing_IMG_7670.jpg?1569515068) ## Parts ### [**Xenomorph candy bucket!**](https://super7.com/collections/alien/products/alien-superbucket-alien) This is a licensed product produced and sold by Super7.

If you've never used the Circuit Playground Express with MakeCode before, [this guide is a good place to start](https://makecode.adafruit.com/courses/maker/general/coding). ## The Code The code is shown below. For browser viewing, you may need to enable content. For example, in Chrome, click "Show Embedded Content" as the material is fed not from Adafruit but from Microsoft's MakeCode site. To download the code, click the download link at the bottom of the window. To edit the code in MakeCode, click the box with arrow icon in the upper right corner of the window. https://makecode.adafruit.com/04647-00178-84857-99936 ## How to Upload Code To upload code to Circuit Playground Express, follow these instructions: 1) Connect your Circuit Playground Express to your computer using a micro USB cable and **press the small reset button** in the center of the board. All the LEDs will flash  **red ** briefly **, then turn green. ** Your computer should now show a removable drive called  **CPLAYBOOT. ** 2) Click the  **Download**  button in the code window below to download the ** .UF2 file**  to your computer. 3) Now ** drag and drop the .UF2 file onto the CPLAYBOOT**   **drive**  in your computer's file explorer or finder. Once the file is dragged onto  **CPLAYBOOT**  the drive will automatically eject itself (your computer may give you a "failed to eject drive correctly" error, you can ignore this). The code is now on your Circuit Playground Express and ready to run! Note: If you get a drive named  **CIRCUITPY** , no worries! Press the reset button  **twice**  to get a flash drive named  **CPLAYBOOT**. The project will not run if copied onto the  **CIRCUITPY**  drive as it is for CircuitPython. ![](https://cdn-learn.adafruit.com/assets/assets/000/081/439/medium800/3d_printing_Screen_Shot_2019-09-25_at_5.04.44_PM.png?1569445514) ## Adjust Your Motor Adjusting a continuous rotation servo so that it stays completely still when inactive can be accomplished by adjusting the potentiometer hidden inside the motor. Take a small screwdriver and SLOWLY turn the potentiometer screw clockwise, then counter-clockwise, observing how this affects the direction of the motor until you find the spot where it stands still ![](https://cdn-learn.adafruit.com/assets/assets/000/081/534/medium800/3d_printing_IMG_1662.jpg?1569619811) ## Troubleshooting **Problem** : My motor doesn't move! **Solution** : Make sure that your Circuit Playground Express is connected to a power source (anywhere between 3V-5V is safe). If you're using a AAAx3 battery pack, check that the switch on the ** ** battery pack is set to "ON". If you are using the LiPo battery, be sure it is fully charged using the charger in the Featured Products.   **Problem: ** My Circuit Playground Express doesn't show up as  **CPLAYBOOT** **Solutions:** 1. Be sure you have a Circuit Playground Express.  The Circuit Playground Classic will not work with MakeCode. 2. If you get a drive named  **CIRCUITPY**  instead, press the reset button twice in succession to get to  **CPLAYBOOT**. 3. Some USB cables are "charge-only" and won't pass data. Try using a different USB cable and try using a different USB port on your computer.   4. With the Circuit Playground Express plugged into your computer with a micro USB cable,  **click the small reset button**  in the center of the board. The lights should all turn green. If they don't, try  **double-clicking**  the reset button. If things still aren't working, head over to the Intro to [Circuit Playground Express](https://learn.adafruit.com/adafruit-circuit-playground-express) guide for more suggestions. ## More MakeCode! If you enjoy MakeCode and want to continue exploring you can check out [lots more MakeCode projects on the Adafruit Learn System](https://learn.adafruit.com/category/makecode). ## Want to Get Back to CircuitPython? If you ever need to convert your Circuit Playground Express back to CircuitPython mode, you can do so by downloading the appropriate .UF2 file from [CircuitPython.org](https://circuitpython.org/board/circuitplayground_express/) and dragging it over onto your  **CPLAYBOOT**  drive. [See this guide page](https://learn.adafruit.com/adafruit-circuit-playground-express/circuitpython-quickstart) for the step-by-step instructions. # Xenomorph Halloween Candy Bucket ## Xenomorph Modification ## Access Port Start by using a pencil to trace the outline of the square you'll cut in the front of the bucket. Use a sharp hobby knife to \*carefully\* puncture the plastic and cut out a section large enough for the candy receptacle to fit through.  Check that everything will align correctly. ![3d_printing_IMG_7635.jpg](https://cdn-learn.adafruit.com/assets/assets/000/081/489/medium640/3d_printing_IMG_7635.jpg?1569535929) ![3d_printing_IMG_7632.jpg](https://cdn-learn.adafruit.com/assets/assets/000/081/490/medium640/3d_printing_IMG_7632.jpg?1569536041) ![3d_printing_IMG_7653.jpg](https://cdn-learn.adafruit.com/assets/assets/000/081/525/medium640/3d_printing_IMG_7653.jpg?1569606441) If you don't have an X-acto knife, the 3D printed handle used here can be found on [Thingiverse](https://www.thingiverse.com/thing:17551) and pairs well with standard utility knife blades to make an excellent hobby knife. ## Candy Receptacle Cut off the end of a cardboard tube, about 1" tall. A paper towel tube works great for this purpose. Trace outline of the tube on a piece of thin cardboard. Cut around this circle.  Glue this circular piece of cardboard to the end of the tube. ![3d_printing_IMG_7546.jpg](https://cdn-learn.adafruit.com/assets/assets/000/081/453/medium640/3d_printing_IMG_7546.jpg?1569515263) ![3d_printing_IMG_7548.jpg](https://cdn-learn.adafruit.com/assets/assets/000/081/454/medium640/3d_printing_IMG_7548.jpg?1569515815) ![3d_printing_IMG_7550.jpg](https://cdn-learn.adafruit.com/assets/assets/000/081/455/medium640/3d_printing_IMG_7550.jpg?1569515919) ![3d_printing_IMG_7551.jpg](https://cdn-learn.adafruit.com/assets/assets/000/081/456/medium640/3d_printing_IMG_7551.jpg?1569515965) ## Servo-Ready Now it's time to attach the tube to our micro servo motor. This will enable the receptacle to flip upside down inside the bucket, depositing its candy inside. Glue servo arm to the edge of the cardboard tube using plenty of hot glue. ![3d_printing_IMG_7627.jpg](https://cdn-learn.adafruit.com/assets/assets/000/081/457/medium640/3d_printing_IMG_7627.jpg?1569516047) ![3d_printing_IMG_7629.jpg](https://cdn-learn.adafruit.com/assets/assets/000/081/458/medium640/3d_printing_IMG_7629.jpg?1569516121) ## Xenomorph Makeup Using spray paint or a paint brush, paint the candy receptacle silver. Add the outline of teeth with a dark permanent marker, matching the teeth on the bucket as closely as you can. Once you're satisfied with the look, press the candy receptacle firmly onto the servo horn, and use some electrical tape (or black paint) to cover up the servo motor. ![3d_printing_IMG_7673.jpg](https://cdn-learn.adafruit.com/assets/assets/000/081/462/medium640/3d_printing_IMG_7673.jpg?1569517957) ![3d_printing_IMG_7647.jpg](https://cdn-learn.adafruit.com/assets/assets/000/081/465/medium640/3d_printing_IMG_7647.jpg?1569518403) ![3d_printing_IMG_7698.jpg](https://cdn-learn.adafruit.com/assets/assets/000/081/493/medium640/3d_printing_IMG_7698.jpg?1569536997) ## Install Linear Actuator Use double-sided tape to secure the linear actuator system inside the bucket, or use the holes provided in the linear actuator base to use two bolts to hold it firmly in place. Cable management is important! Use tape or twist-ties to keep all your wires tidy. Black electrical tape works well, and also looks great. ![3d_printing_IMG_7636.jpg](https://cdn-learn.adafruit.com/assets/assets/000/081/495/medium640/3d_printing_IMG_7636.jpg?1569537497) ![3d_printing_IMG_7652.jpg](https://cdn-learn.adafruit.com/assets/assets/000/081/496/medium640/3d_printing_IMG_7652.jpg?1569537511) ![3d_printing_IMG_7701.jpg](https://cdn-learn.adafruit.com/assets/assets/000/081/497/medium640/3d_printing_IMG_7701.jpg?1569537567) ![3d_printing_IMG_7650.jpg](https://cdn-learn.adafruit.com/assets/assets/000/081/498/medium640/3d_printing_IMG_7650.jpg?1569537641) ![](https://cdn-learn.adafruit.com/assets/assets/000/081/530/medium800thumb/3d_printing_IMG_7719.2019-09-27_16_15_26.jpg?1569615438) ## Alien Drool As a final touch, you can use hot glue around the mouth to add some attractive-looking Xenomorph spittle.  ![](https://cdn-learn.adafruit.com/assets/assets/000/081/492/medium800/3d_printing_IMG_7700.jpg?1569536935) ![](https://cdn-learn.adafruit.com/assets/assets/000/081/547/medium800thumb/3d_printing_Untitled.2019-09-26_17_35_25.jpg?1569623474) ## Featured Products ### Circuit Playground Express [Circuit Playground Express](https://www.adafruit.com/product/3333) **Circuit Playground Express** is the next step towards a perfect introduction to electronics and programming.
