Introduction: DIY: a Pocket Sized Cotton Candy Machine!
Did you ever have a random craving for cotton candy? Wanna impress people in school? Bored and hungry in the middle of nowhere?
Fear not, i made a guide for an ultra compact cotton candy machine!
Back when i was in the 5th grade i was inspired to build this cotton candy machine but i didnt have enough parts or skill either so thank you so much bangbang007 go check his projects out! he's got some pretty cool robots and taught me how to inflate dented pingpong balls! (i can play beer pong again hehe)
I'd like to thank my friend monty for lending me his frickin awesome camera
Oh, if you guys have some time please do vote for my entry in these contests, it would really help me out a lot if i had better tools and a decent camera so i could improve on my instructables. thanks so much!
anyhow, let's get started!
Step 1: The Gathering
- Long (nose) lighter
- Torch/Jet flame lighter
- 2 small 250ml cans
- short metal standoff with screw and nut
- 3 washers
- A large DC Motor
- 2 AA Batteries
- 2 AA Battery holder
- Soldering iron
- Push pin
- Screwdriver with an assortment of bits
- Clay epoxy or 2 part epoxy
- Drill (optional)
- Hot Glue gun
- Superglue or any cyanoacrylate adhesive
Step 2: The Chamber
Ayt, so the parts we need for this step woud be:
- 2 250 ml Cans
- A screw with a matching nut
- 3 Washers
- A Push pin
- Your Dc motor
- Short metal standoff
So, sand down the bottoms of your two cans and cut it atleast half an inch, be real careful cause aluminum cans tend to spring back and could cut you!
Using a push pin, prick holes at the corner of the can (see picture 4) then cut it off as well. then with your marker, find the EXACT center of the bottom of the can and drill a hole that the screw would fit on.
So this is the hardest part of the step....With the first half, take your cutter and try to remove as much of the bottom part as you can and then with your pliers, bend off any remaining pieces inward so you don't cut yourself.
Once that's done, install your screws and put both cans together!
With your metal standoff, secure it to the shaft of your Dc motor with some superglue. (See Picture 10)
Step 3: I See Fire (Heating System)
Ha haha hah see my reference to the song??......okay nevermind.
Anyway, in this step you're gonna need:
- A long nosed lighter
- A Jet flame / torch lighter
- an assortment of wires
So you'll need to open both lighters and once they're both gutted out, see Pic 2 for the parts you'll be needing....if the part wasnt mentioned, you will not be needing it so just put it in your scrap parts for another project.
Okay, did you check out the picture? Good. so glue the torch to its housing then look at image 5, see that hole? put the main ignition wire (the black wire connected to the side of the piezoelectric igniter) through that and bend it just like in image 7.
now you will want to glue the ignition wire (the wire connected to the metal base of the piezoelectric igniter) exactly like in image 8, DON'T block the hole above it!
once that's all done, give your igniter a squeeze and see if there is a spark gap between the orch and the wire. If so, connect your silicone fuel hose to the torch and fire it up!
Step 4: Electronics and Planning
So the electronics here are really simple, we're gonna need:
- Your 2 AA batteries and holder
- The Dc motor
- The Project enclosure (box)
- Some wires
- A switch
- A hot glue gun
- And a soldering iron
So first off, heat up your Glue gun and glue the switch to the other end of the battery holder and then take your box and plan wherever you wanna install it.
Solder your Dc motor with it's corresponding polarites and solder the switch.
Step 5: The Mark (Planning and Drilling)
Okay...so here's the kinda boring part of the process...We're gonna need:
- A marker
- All the assembled parts from my previous steps
- the project enclosure
- and a drill
So first off, take the top half of the chamber and place it on your enclosure, make sure its centered on the box. Then take your motor and place it on the Center of the can. Dont' forget to mark it! (See images 2 and 3 for reference)
Okay now that's done, take your large fuel tank and mark the top on the side of the box, make sure there is space for the fuel adjustment. (See Picture 4)
okay, now align the fuel tank to where you marked your top and then take the bottom of the tank and mark it's hole on the other side of the box. (See Picture 5)
Next, take your igniter and mark a hole for it on the top of the box. (See Picture 8)
Take your battery holder and switch, mark holes for the wires for the switch and the battery holder, (see pictures 6 and 7)
now drill all the holes you marked earlier!
Step 6: The Assembly
Wow, glad that's over. Now for the best part!
We're gonna need:
- Clay epoxy / 2 part epoxy
- Hot Glue gun
- All the assembled parts from the previous steps
Take a Chunk off your clay epoxy and knead it, then place it around the igniter, don't forget to put tape on the holes of the igniter! and then add epoxy around the motor (See image 3)
Then you're gonna want to hot glue the fuel tank to the project enclosure, just glue the upper part of the fuel tank, NOT the part where the butane is stored.
Once the motor is installed, screw the chamber to the shaft of the motor. now in this step, we're going to plot where the torch should be placed, you should make the flame touch the "x" mark on the can (See image 7 For reference) and then mark a hole for the torch for drilling. Once installed, add clay epoxy around it. (see image 10)
now take your battery holder and switch and thread the wires to it's corresponding holes. (see image 13) and hot glue the battery pack in place.
finally, connect the positive wire of the battery to the motor's positive and connect the negative of the motor to one of the switches' wires. then connect the batteries' negative to the switches' other wire. Insulate exposed wires with hot glue. (see the second to the last picture)
Step 7: How to Use Your Machine
Ah, time to reap the fruit of your labor, now here's how to use it!
First you're gonna want to make the collector, i just used some paper taped together to form a large tube! (plus points for being eco friendly?)
add a teaspoon of sugar to the chamber where the torch is, then turn on the torch to heat it up a bit then flick the switch! Boom. Cotton candy. Use a bamboo skewer to collect your prize!
Hey guys heads up for updates! Don't forget to leave a comment for your thoughts and suggestions or simply if you liked my project!
Coming soon: variable speed control
Camera used: Sony NEX-5
so yeah, whether you always wanted go start a business at the back of the classroom or simply just make your classmates kneel in awe, this is cotton candy machine does it's job well.
have fun flinging molten sugar!
