Emotions are everywhere, and they can attack at any time (Trust me. I speak from experience). But hey, that's life! And if you're anything like me, you want to find a way to deal with your emotions hands-free. Wow!
With the Crying Helmet, you can do just that! This helmet simultaneously wipes your tears, pats your back, and shows you encouraging messages, so you can leave your house each day with the confidence that even if emotion strikes, you WILL be prepared.
I got you, fam!!
Step 1: Gather Your Materials
Step 1 is to gather your materials.
You will need:
Laser cut parts (Download link: )— this file includes parts such as your motor holders and the pieces that allow you to mount parts to your helmet
3 x Standard Servo Motors
2 x 6in dowel rod
2 x 12in dowel rod
1 x Continuous Rotation Motor
2 x Micro Servo Motors
5 x 9v batteries/battery clips
1 x Arduino Uno
1 x Glove
2 x Popsicle Sticks
1 x notecard
1 x Screw eye (either metal or plastic)
1 x helmet
Double Sided Tape
Machine Screws of varying length
Single Edge Pull Saw
Hot glue gun
Step 2: Assemble Your Tear Wiper
Put Together Each Wiper Arm:
1. Drill three holes at the end of your 6in dowel rods in order to attach them to your motor arms
2. On the other end of your 6in dowel rods, drill two more holes to attach it to your acrylic micro servo mount
3. Place your micro servos in the mounts
4. Fold your paper towels into two 1in x 2in squares and hot glue them to the ends of your popsicle sticks
5. The other ends of your popsicle sticks can be attached to the motor arms of the micro servos
Attaching Everything to your Helmet:
6. Drill three holes in the front of your helmet to match the holes in the middle of your "Tear Wiper Base Plate"
7. Attach the base plate to the front of your helmet using machine screws
8. Using your cable ties, attach two of your standard servos to either end of the "Tear Wiper Base Plate"
9. Attach each of your tear wipers to your standard servos
Step 3: Assemble Your Encouraging Messages Reel
Put Together your Motor Reel:
1. Get your three circle pieces. Find the larger circle piece with five holes
2. Cut 18in of fishing line and tie one end of the fishing line to the two holes not in the center of the circle (refer to picture above)
3. Stack your three circles and attach to a motor arm using machine screws
Attach Your Motor:
1. Using machine screws, attach your continuous rotation motor to the c-shaped motor holder
2. Drill three holes in one of your 12in dowel rods and attach the motor holder to the end of the dowel rod
3. Attach your Motor Reel to the continuous rotation motor
Attach Everything to your helmet:
1. Drill four holes at the top of your helmet to attach the "Messages Reel Base Plate" to the top of the helmet
2. Attach using machine screws
Step 4: Assemble Your Back-Patting Mechanism
Attach Your Glove:
1. Fill your glove with cotton
2. Using a Cable tie, attach it to the end of your remaining 12in dowel rod
Attach Your Dowel Holder:
1. Find your two half-circle laser cut pieces
2. Drill eight holes at the base of your helmet. Each should be separated by the width of your acrylic. They should line up with the holes on each half-circle acrylic piece.
3. Using cable ties, secure each of the half-circle pieces to the back of your helmet
4. Thread a longer machine screw through the holes in your half-circle acrylic piece. This will act as the axle for your dowel rod (refer to picture)
Attach Your Motor Holder to the Helmet:
1. Using cable ties, secure your motor holder to the Back-Pat Base Plate
2. Cut the excess cable tie and drill holes to attach the base plate on top of the helmet, behind the existing "Encouraging Messages Base Plate"
Attach Your Motor:
1. Attach your motor arm to your Back Pat Cam (marked in the .dxf file)
1. Attach your screw eye to the dowel rod about an inch from the axle
2. Tie one end of your fishing line to your dowel rod right where your glow is cable tied. Thread the fishing line through the screw eye, and attach the other end to the hole in your "Back Pat Cam"
3. Take a moment to manually move your "Back Pat Cam" to see how the arm will move, and adjust the length of the fishing line accordingly
Step 5: Attach Your Arduino and Breadboard
Attach Arduino, Breadboard, and batteries:
1. Using your double-sided tape, attach your Arduino, batteries, and your breadboard to the "Arduino Base Plate"
2. Drill two holes in your base plate and attach to the side of the helmet using machine screws
1. Cut and solder wire from each of your motors to your breadboard
2. Wire according to the diagram
Step 6: Test It Out/Enjoy Your Emotions
Download the Arduino code and you're good to go!
Enjoy your emotions, my friend.....just do it.
