A Snowman and Gingerbread Man Candy Cane Ornament

A Snowman and Gingerbread Man Candy Cane Ornament 

Candy canes are sweet treats that are loved by many children and adults alike.  In this blog posting, https://turtlestitch.blogspot.com/2024/12/embroidering-candy-cane-snowman-ornament.html  I 
coded a snowman and a gingerbread man in TurtleStitch to embroider on felt.  I used its design to create this paper version.  The paper version of the snowman and gingerbread man can hold two candy canes.  It looks adorable because the candy canes look like the snowman/gingerbread man's arms and legs.

I  used 65 lb. cardstock and foil cardstock from Michaels and a four inch piece of ribbon as a hanger.

Here is the PDF if you would like to print and cut with scissors.

Here is the .Studio file for the Silhouette cutting machine.

Here is the SVG for all other electronic cutting machine. The file goes beyond the viewable area.  Zoom out to see the entire file.

Bend all of the tabs of the body. Glue the two parts of the body together. Fold the ribbon in half and insert the ribbon in the center of the head. (I pulled the head apart at the top tab and added additional glue and then inserted the ribbon.). 

Glue on the embellishments. 
As an alternative to the glued on embellishments, it might be fun for a child to color on their own design.

Wait for the glue tabs to dry before inserting the candy canes.  I inserted the candy cane through the armhole. Gently expand the armhole and thread the candy cane through the hole.

A STEM Project: Using a Brown Dog Bit Board With A Microbit to Rotate a Christmas Carousel

Using a Brown Dog Bit Board With A Microbit to Rotate a Christmas Carousel

The Microbit has a limited power supply of 3 volts. Motors that are powered by the Microbit, do not run well or not at all because of the limited power draw. I used a Brown Dog Crazy Circuits Bit Board. https://www.browndoggadgets.com/products/crazy-circuits-bit-board to expand the capabilities of my Microbit to use a continuous rotation 360 degree servo https://www.browndoggadgets.com/products/brick-compatible-360-degree-servo

Using the Christmas Carousel that I designed in this posting, https://papercraftetc.blogspot.com/2020/11/a-christmas-carousel-with-color.html I added a Lego axle to the center column to attach it to a continuous rotation 360 degree servo to make this carousel move.

Here is a video of the Carousel in action.

Programming The Microbit

Here is the program that I used to operate my Microbit,


The program does a few things.  It streams the message "Happy Holidays" across the LED display. When the left button is pressed, the song "Deck the Halls" plays and the carousel rotates clockwise. When the right button is pressed, the carousel stops rotating.

Connecting the Microbit to the Brown Dog Bit Board

The Microbit is connected to the Brown Dog Crazy Circuits Bit Board as shown above.

I boxed in the battery power supply with Legos and added a glue dot to the bottom of the battery compartment so that the battery would not move around.

The battery is connected with the red and black wires to the bit board at the red connector, shown above in the middle of the photo. The red wire is positive and the black wire is negative.

The continuous rotation 360 degree servo is connected via the orange, red and brown wires to the bit board at the location of pin 0. The colors of the servo wires correspond to the colors of the pins. Check to make sure the servo works before continuing to attach the carousel.

Connecting the Carousel to the Continuous Rotation 360 Degree Servo 


I attached the carousel with a Lego axle and two gears to add stability at the point where the axle and the servo meet.  There is a little wobble as the carousel rotates.  The wobble is more apparent at higher speeds.  At a 50% running rate, the wobble is very slight.

A STEM Project: A MIcrobit Project For Christmas Using the Silhouette

A Microbit Project For Christmas 

Rudolph The Red Nose Reindeer and Frosty The Snowman characters are placed over a red LED light. The supporting box for the Microbit was cut with the Silhouette paper cutter.

When the Micobit is activated by pressing the left button, a song is played. When the right button is pressed, a different song is played.  Can you guess which songs are going to be played?

Here is a video of the Microbit in action.

A Microbit is an easy and inexpensive way of learning to program.  I purchased my Mictobit at Microcenter for $22.  I think the Microbit is a bargain because of all of its programming capabilities that are packed into this little device. The Microbit has an LED display, it can emit sound, it has light and temperature sensors, radio and Bluetooth sensors to transmit between two Microbits and two programmable buttons to name a few features.

The Microbit website, https://microbit.org has tutorials to help you learn programming using Microsoft MakeCode for beginners. Python and Scratch programming languages are also available to program the Microbit for more advanced learners.

In my previous blog posting, I make a wrap  for the Microbit to contain the battery to allow for easy access to the connectors  https://papercraftetc.blogspot.com/2024/11/a-stem-project-microbit-battery-holder.html. I used this wrap for my Microbit.

Box and Reindeer/Snowman Instructions

Cut out the box to contain the Microbit and embellishments.

Here is the PDF.  I used 65 lb. white cardstock for the design. 

Here is the .Studio file for a Silhouette cutting machine.

Here is the SVG for all other electronic cutting machines. I included a one inch square for reference.

Crease the box as shown above.  Apply glue to the two tabs at the left side of the photo.

Adhere the tabs and apply glue to the two small tabs as shown above.

Insert and adhere the small tabs into the bottom of the box. Apply glue to the side of the Microbit holder tabs.

Adhere the Microbit holder tabs to the inside of the box.

Insert the Microbit by wrapping the box around the Microbit's buttons.
Embellish with a paper candy cane.

Embellish the Snowman and Reindeer as shown above.

LED Light Instructions

Using a red LED light, (please note, the longer wire is positive), I made a holder for this LED light by using the following instructions in this YouTube video.  https://youtu.be/jmsu__UYTl8?si=dS8hfbSRW0h7QUfb 
Assembly Instructions


Once the red LED holder was made, I used two alligator clips; a red alligator clip was used for connecting the positive side of the light to pin 0 at the bottom of the Microbit .

A black alligator clip was used for the connecting the ground side of the light to pin GND at the bottom of the Microbit. In the photo above, alligator clips are attached at the back side of the Microbit.

Programming Instructions

Here is the program that I used to operate my Microbit, https://makecode.microbit.org/S41653-41913-44926-20051 The program does a few things.  It streams the message "Merry Christmas" across the LED display. The red LED blinks on and off. When the left button is pressed, the song "Rudolph the Red Nose Reindeer" plays. When the right button is pressed, the song "Frosty the Snowman" plays.

 
Side View

When playing the left button on the Microbit, use the reindeer embellishment for the "Rudolph the Red Nose Reindeer" song. When playing the right button, use the snowman embellishment for the "Frosty the Snowman" song.

A STEM Project: A Microbit Battery Holder With Accessibility For Edge Connectors

A Microbit Battery Holder With Accessibility For Edge Connectors

On the Microbit website, they feature a cardboard battery holder for the Microbit.  https://microbit.org/get-started/user-guide/battery-pack-holder/ While it is a great design to hold the battery pack.  I had issues with the bottom edge connectors. I added two alligator clips to the ground and 3v ports. When I stood the battery holder upright up, standing on the bottom edge of the battery holder, the Microbit tilted to the left side. 

My goal was to create a Microbit battery holder that would stand up at a right angle to the table for easy front viewing without the issue of accessing the bottom edge connectors. In my design, I used the original Microbit battery holder design and I modified it. I extended the sides of the battery holder and added a triangular corner to each side.  I made triangles at the bottom corners because triangles are the sturdiest structure.  It is a shape that can not be distorted by stress because the load is distributed evenly across all three sides of the triangle. The result is a corner that will not collapse under the weight of the Microbit. If you exert pressure at the top of this holder, the side will bend but not the triangular corners.

Here is the PDF.  I used 65 lb. white cardstock for the design. 

Here is the .Studio file for a Silhouette cutting machine.

Here is the SVG for all other electronic cutting machines. I included a one inch square for reference.


Crease all of the dotted lines with a valley fold. Apply glue to the two bottom tabs as shown above.

Fold the two bottom tabs with the glue inward to create a triangular pyramid on each side.

Insert the battery wire through the hole on the side.

Insert the tab into the center hole. 

Wrap the square hole around the Microbit button.  Repeat for the other button.

Apply glue to the bottom of the triangles.

Adhere the bottom piece to the holder.

The edge connectors can be accessed from the front.

Or the back of the holder while standing upright.

A STEM Project: A Rubber Band Pop-Up Gingerbread House

A Rubber Band Pop-Up Gingerbread House - Side View #1

Side View #2 

Here is a video of the pop-up in action.

 This rubber band pop-up card is an engineering marvel.  It combines a rubber band mechanism with a house which pops-up when removed from an A4 envelope. An A4 envelope is 4 1/4 in. x 6 1/4 in. The recipient of this card will be astonished when the flat card opens into this amazing three dimensional gingerbread house for Christmas.

The rubber band expands when the base is pressed down at the seam that is opposite to the internal diagonal.  When the side pressure is released, the expansion tension on the rubber band is released and the rubber band returns to its natural state  This phenomenon allows the form to deploy and become three dimensional.

For my papercrafting friends, no coding is necessary.  All the files for the pop-up gingerbread house are included. 

The entire gingerbread design with the embellishments were coded in TurtleStitch and then opened in the Silhouette program for cutting. 

Here is the PDF.  I used 65 lb. white and green cardstock, red foil cardstock and red glitter cardstock. I used the back of the red foil cardstock for the gingerbread man as it was brown.

A one inch rubber band is required for the pop-up base. (The rubber band is similar to the rubber band used on a Rainbow Loom.) I also used one glue dot. 

Here is the .Studio file.

Here is the SVG.

Make the Pop-Up Rubber Band Base - Here is the code that I used to create this pop-up rubber band base in TurtleStitch. https://www.turtlestitch.org/users/Elaine/projects/Rubber%20Band%20Pop-Up%20Mechanism

There are two sides to the rubber band base. Each side is folded over to create a two-ply base. Crease the paper as shown above.  

Glue the folded sides together.

Glue the tabs together. Make sure that the slits are going in the same direction.

Slide the one inch rubber band into the slit and align the rubber band with the round hole in the base of the slit.

Fold the base so that a square is made with a diagonal in the middle.  Slide the rubber band into the slit and align the rubber band as before. There is a gap in the diagonal.

Apply a Glue Dot into this gap.

Rubber Band Base
The base can be flattened when the corners without the diagonal are pressed inward.

Make the Gingerbread House - Here is the code that I used to create this gingerbread house and roof in TurtleStitch.  https://www.turtlestitch.org/users/Elaine/projects/Gingerbread%20Cottage%20-%20Rubber%20Band%20Pop-Up

Wrap and glue the velum to the pop-up base as shown above.  Do not use a lot of glue.  I glued just the base of the vellum.

Apply glue to the top and bottom of the vellum as shown above.

Fold the gingerbread house wrap around the vellum.

Apply glue on the roof beam and fold in half.

 Splay the side tabs outward as shown above.

Glue the splayed tabs to the peak of the house on both sides.  Allow the roof beam to dry before proceeding.  Apply a good amount of glue to the top of the roof beam as shown above.

Glue the one roof piece to the other roof piece.

Center the smaller roof piece to the center and apply a good amount of glue to the center seam.

Attach the roof to the gingerbread house.  Make sure that the roof is centered by looking at the overlap of the roof on both sides.


Embellish the Gingerbread House with a Gingerbread man, swirls candy, candy canes and a wreath with a bow.

 
Glue on the embellishments to the house as desired. 

The tree was created by gluing two trees together at the dotted center line with a thin line of glue.  Once the glue is dry, the top tree is splayed outward.

Here is the code that I used to create this tree in TurtleStitch. https://www.turtlestitch.org/run#cloud:Username=Elaine&ProjectName=tree 

Here is the code that I used to create the gingerbread man in TurtleStitch.

Here is the code that I used to create the swirls candy in TurtleStitch.


The candy cane was made by glueing two types of cardstock together. The one layer with the swirls was white cardstock and the other layer was red foil cardstock.

Here is the code that I used to create these candy canes in TurtleStitch.

The bow on the wreath was made with red glitter cardstock.  The center circle of the bow was glued on and then the entire bow was glued to the wreath.

Here is the code that I used to create this wreath and bow in TurtleStitch.

Oval Slice Form Pumpkin with Thanksgiving Scene Inside

Oval Slice Form Pumpkin with Thanksgiving  Scene Inside
To see the individual slices of the Thanksgiving scene, I recommend looking at the PDF file below.

The Thanksgiving scene can rotate as there is a gear in the base of the design.

I  used Neenah brand 65 lb Champagne Pearl metallic cardstock from Office Depot.  The lettering on the round base that says "Happy Thanksgiving" can be cut out from card stock, Foil Quilled or sketch penned.

Here is the PDF. 

Here is the .Studio file.

Here is the SVG. The file goes beyond the viewable area.  Zoom out to see the entire file.

The directions to make the slice form are in this blog post.https://papercraftetc.blogspot.com/2020/10/a-birthday-slice-form-sphere-that.html


The brown slices for the stem are slid into the yellow stem that is protruding from the yellow center oval slice. Glue on the leaves and the two strips that have been curled to complete the model.
