Introduction: Make a Fun Paper Planes Launcher

Hi everyone!
In this ible I'l show you how to build a fun Paper Planes Launcher for free.

I build it in less than an hour and I used just materials that I had already at home as a strawberry box, two CDs, two little motors and four AA batteries.

If you want to have fun YOU HAVE TO build this cool Paper Planes Launcher.

VIDEO: in this video above you can see it working. I filmed it with both CD options. Unfortunately when I put the transparent CDs on, the batteries were a little low so it seems like they are less powerful, but trust me that they work at the same way.

Step 1: Materials & Tools

MATERIALS:

- 1 strawberry wooden box

- 1 piece of wood (2cm x 4cm x 20cm)

- 2 CDs and a small piece of cardboard

- 2 motors (I took them by old Mini 4WD)

- 4 AA batteries

- 2 AA battery holders (0.14$)

TOOLS:

- handsaw, file and sandpaper

- hot glue gun

- black spray paint (optional)

Step 2: The Base

For the base I used a scrap piece of wood 2cm x 4cm x 20cm.

I initially cut it in two pieces of 2cm x 2cm x 20cm, and then I cut one of them 2cm x 2cm x 16cm.

In order to make a flat cross I made a groove 2cm x 2cm (deep 1cm) on both pieces using a handsaw and a file.
On the shorter piece the groove is located in the center, while in the longer piece it's located at 9cm from one end.

Since I made the grooves very precises I didn't used glue, but if you have any gaps or if you want to make the base sturdier I suggest you to apply a little amount of hot glue between the two pieces.

Step 3: The Structure's Pieces

For all of the remaining wooden pieces of the structure I used pieces taken from a strawberry box.

I cut them with an handsaw, and since I didn't like the words, I painted them with black matte spray paint. (This is optional! You can paint them or not. Do what you like.)

From the corners pieces of the fruit box:
2x (1,5cm x 2,5cm x 2,5cm)

2x (2cm x 2,5cm x 2,5cm)

2x (3cm x 2,5cm x 2,5cm)

From the borders of the fruit box you will need:
2x (3,5cm x 4cm)

2x (4cm x 4cm)

2x (3,5cm x 8cm)

2x (4cm x 8cm)

Step 4: The Rear Support

NOTE: this step is easier to understand in photos rather than in words. ;)

In order to built the rear support you will need (picture 1 from the left to the right): one (3,5cm x 8cm) piece, one (4cm x 8cm) piece, and one (3cm x 2,5cm x 2,5cm) piece.

Start to glue the smaller border piece on one side of the longer arm of the cross. (photo #2)

Then take the other border piece and attach it to the previous, and finally glue the corner piece on its center.

Step 5: The Front Support

Repeat the process of the previous step to make the front support.

This time you have to use one (1,5cm x 2,5cm x 2,5cm) piece, one (3,5cm x 4cm) piece, and one (4cm x 4cm) piece.

NOTE: the only difference from the previous step consist in glueing the little corner piece to left side of the (4cm x 4cm) piece as in photo #4.

Step 6: Finish to Build the Structure

Repeat the last two steps for the other side of the base, and you should get something like what you can see in the first picture.

Then take off the gears from the motors, and use hot glue to attach the motors to the remaining (2cm x 2,5cm x 2,5cm) pieces.

Step 7: The CDs - First Option

I used two of those plastic clear CDs from the bottom of a stack of discs, but you could use two old/broken CDs.

Cut two little circles of cardboard, and glue them in the center of the CDs. Then reverse them upside down and glue the gears in the center. Be very precise to place the gears right in the center, of the CDs will not spin correctly.

Be also careful to put the gears parallel to the CDs, to do this easily I inserted a motor in the gear, and I checked that is was perpendicular to the CD. (photo #4)

Finally I used hot glue to attach a rubberband around both of them. It will give a lot of grip to the CDs.

Step 8: The CDs - Second Option

A second option for the CDs is this one. A round craft foam sheet glued between two CDs.

I marked and cut two circles 3mm bigger than a CD.
Then I cut 4 small circles out of an old credit card, and I placed them in the center of the foam circles. As you can see in photo #4, now the plastic circle fit perfectly in the bigger foam one.

It's time to make the sandwich! ;)
Start by gluing the plastic circle in the center of a CD. Then apply more glue on the CD and press on the foam circle. Glue another small circle in the center, and finally glue on the other CD.

This second option it's sturdier but works perfectly as the "rubberband one". I made it too because I already had it in my mind so I was curious if it could have worked better (or not).

Step 9: Glue the Motors and the Ramp

I inserted the CDs (without gluing them for now) onto the motors, and I placed them on the structure. I moved them on the shorter leg of the base until they were centered and spaced about 3mm from each other, and I marked a line with a pencil. (photo #2)

Then I used hot glue to attach them in the right position, and I checked if was all ok by spinning the CDs by hand.

Finally I cut two pieces of 30cm x 3,5cm from the base of the strawberries box using a x-acto knife and a metal ruler.

As last thing I glued these two ramps at the structure placing them about 5mm from each other. (photo #5)

Step 10: Connect the Motors to the Battery Holders

Connect the wires of the AA battery holders to the motors, and glue them on the base as in these pictures.

Do not connect the wires with the batteries inserted, and be sure to connect them in the right way. The left motor should rotate counterclockwise, while the right motor should rotate clockwise. Only in this way they can suck in the paper plane, and throw it forward.

To correct the rotating direction you have to swap the positive wire with the negative wire.

Step 11: Final Touches

Once everything works as it should, you can put a little drop of hot glue to secure better the CDs to the motors.

In order to make it more stable I put 4 rubber feet under the main structure.

Insert the four AA batteries into the battery holders, and do some tests. If the CDs don't grab the paper airplane, you have to re glue them a little bit closer. (This also depends from the thickness of the base of your airplane, so you have to play with these two dimensions until everything works)

Step 12: Finish!! Build Some Paper Planes and Have Fun

You can obviously paint it as you want, and you can also change materials and dimensions. I suggest to add a switch so you don't have to insert and remove the batteries every time you use it.

If you build one, please post a photo of your result in the comments section below.

I hope that you liked this very cool project!

This was great fun to make, and finally works very well - the trickiest part is attaching the cd's centrally to the motor spindles, eventually plenty of glue-gun helped :-)

Also, we added a push switch, used pairs of cd's stacked on eachotehr to make the propellign discks, and used the glue-gun to put a grippy edging on the cd's.

Great project!

I might have to make one of these. I gave my little brother (actually he's 49, not all that little) a paper airplane remote control module for Christmas, but one of his arms is in worse shape than I thought, so he can't hold the control unit (smart phone) and throw a plane at the same time.

This might make flying things possible for him again.

Do we really need 2 motors?

Motor mounted on first disc can drive the second disc through friction right?

author

yeah but this means half power, which means that it throws the airplane almost half distance far (or probably less). and the motor is in that way subjected to double work... it may overheat and burn. In other words...I suggest to use two motors ;)

Awesome! I made a similar design from Sonic Dad, but used a large 6V battery to drive both motors. It kept them running at the same speed.

Word of warning though, don't let the motors run too long. Once the discs get up to speed, the motors will be running with virtually no load (the discs' momentum keeping them going). Once that happens, the resistance drops and current rises, causing the windings in the motors to overheat and possibly burning out. It happened to me on my maiden voyage after about 15 minutes of constant running. I installed a momentary switch so that you only ran them when you wanted to actually fly a plane.

Happy flying!

author
manuelmasc (author)yasko2015-05-21

Yeah! infact as i said in the last steps I'll add a switch to run motors just when trowing the planes. and in this way I'll save also power from batteries ;)

BrownDogGadgets (author)2015-05-18

Make a video of this! I'd love to see it in action!

author

I made it! But I had problems uploading it! ;) in the next days I'll solve this "problem"

author

When in doubt, just upload one to youtube. I've had issues uploading things to instructables before. (And a video ALWAYS helps your chances n a contest.)

This is really clever!

I especially like the idea to use rubber bands around the CDs for grip. Nice work!

author
manuelmasc (author)seamster2015-05-20

Check step 8 ;) That is the other CD option

Nice project. how did you make one motor work counterclockwise?

author
manuelmasc (author)ElNats2015-05-20

step 9 ;) I simply inverted the polarity in the connection! ;)

LEFT MOTOR: Right contact > red wire from battery holder

Left contact > black wire from battery holder

RIGHT MOTOR: Right contact > black wire from battery holder

Left contact > red wire from battery holder

Could you possibly use this same concept to make a mechanical crossbow or sort?

author
manuelmasc (author)Brinith2015-05-20

mmm yeah good idea! ;) but I think that in order to throw an arrow you will need more power... maybe you could use bigger and more powerful motors ;)

NathanSellers (author)2015-05-18

Great use of using things you have around the house. What a fun project. My son would love having something like this... Now to find some motors.

author
FriXs (author)NathanSellers2015-05-19

Great sources of motors: rc-cars, electric toothbrush, ol printer...

author
manuelmasc (author)NathanSellers2015-05-18

yeah! Your son will like it for sure!! If you'll make it, post here a "I Made It" photo. ;)

P.S. you could find them in "under the christmas tree" trains, in rc cars, or in cheap milk foamer!

OR EASILY you could buy them online http://www.amazon.com/TOOGOO-12000RPM-65g-cm-Electric-Hobbies/dp/B00TO7IF8O/ref=sr_1_18?s=industrial&ie=UTF8&qid=1431986016&sr=1-18&keywords=dc+motor
