laser-powered light saber - white polycarbonate
Since I saw Star Wars when I was a child, I wanted to make a lightsaber.
A few decades later, I crossed it off my list.
This instructions will show you how to make your own laser sword/lightsaber using laser arrays, e-cigarettes, several fans, switches, and 3D print enclosures.
It's basically harmless and looks great especially at night.
Not as bright as usuallights-in-a-
Tube lightsaber, this one can fall into an object and burn dynamically, with the weightless blade you expect from the real lightsaber.
The idea is simple, it was born on a cold night when I rode home.
While waiting for the lights, I called out along the axis of my 2000 lumens LED bike lights, a bright white beam across the road.
When I got home, I had come up with a plan to make a laser sword.
The main idea is that if I focus some of the laser on a dispersed steam plume, the light output will be roughly stable to the focus, after which the beam and smoke will spread rapidly and therefore disappear, this makes the length of the beam actually Limited.
In the fall of 2016, I am a residential artist at Autodesk's amazing Pier 9 workshop, so what is a better opportunity to realize your childhood dreams?
The trickiest thing I quickly found was focusing on the laser and reliable real estate fog.
My first prototype uses dry ice and laser indicators (first photo)
, Although it proves the concept of sound, the beams are everywhere (second photo)
Dry ice is dirty and shortlived.
Shortly after I arrived at Pier 9, I made a 3D printed laser array (3rd photo)
Connect it to the power supply
Power fog machine (
The kind of party you have)
It looks cool and there is no darkness even outside (Animation above.
After a large number of online shopping for small batteries
Electric commercial fog machine ($800!
Not even so small)
I gave up and designed my own with small fan, 3D printed housing and e-cigarette.
The problem was solved, and then I designed a 3D print array of 12 lasers that can be focused on one point using screws.
It requires a lot of testing and more prototypes than I do for anything (
Except for my 3D periodic table).
The device focuses on 12 beams of laser, creating fog using powerful e-cigarettes.
This is not a toy for children.
If you do one, please use it carefully: do not point the plume of fog or laser to someone's face.
I don't recommend using a more powerful laser than I use to make one.
They are bright enough.
I deliberately don't focus the laser very carefully.
You basically get the same effect without converging all 12 at a particular point in space.
You need to purchase the following parts.
If you want to use a different version, you may need to redesign the 3D printed part (see next step)to suit. -

ScrewsI completed all 3D designs using Fusion360.
I'm new to a solid styling: Fusion360 is the only program I 've ever used, but it makes everything I want to do very easy (take jon-a-
3D printing course for tron if you want to know more).
The Create> pattern> circular pattern tool is especially useful because it makes it trivial to replicate the laser holder.
The rest is carefully measured with calipers.
The final design is the result of many iterations: There are various problems with the prototype, mainly airflow, layout, feel and wiring space.
There is no doubt that there is still room for improvement
It is public if you want to modify this file yourself.
I only ask you to share your adjustments again here.
If you are interested in the design process, please play the screenshot below to see how the design develops (
Jump to 15 seconds at the beginning;
I don't seem to have my editor).
Print two connected parts in 3D using any color and material you like.
I use Stratasys Fortus to print with black ASA and white polycarbonate.
The print is very strong, hard and durable.
Fortus prints the models and brackets with different materials, which means I don't have to worry about the brackets because I know it's trivial to remove them afterwards.
Consider adjusting the design if you are not too lucky.
Combine 3D printing very strongly (another jon-a-tron tip)
, So divide the print into more parts (
I use tasks like MeshMixer)
Then sticking them together might be better than trying to print and remove the stand later.
This part requires patience and certain welding skills.
This may not be your first electronic project.
Start with something simpler, like the instructures Electronics Class. 1.
Strengthen the connection with heatshrink tubing. 2.
Screw all 24 fixing screws into the hole. 3.
Put the laser module into the housing and tighten the screw to the position where it has just come into contact with the laser module.
Repeat 12 times4.
Connect all the red wires together.
I weld 4 sets of 3 wires in each quadrant, then connect two of them together, and then pair them all.
Protect all connections by heatingshrink tubing. 5.
Connect all the blue lines together like the red ones above.
Connect three wires to the switch according to the wiring diagram (
Note that it says 12 V but works fine under 5 V).
I only choose to turn on the LED when the laser sword is turned on.
Pass the wire through the three holes on the side of the sleeve and press the in-place switch.
I use a small rechargeable battery designed specifically to charge my phone.
This device outputs 5 v at temperatures up to 2a, so this app has enough capacity.
Remove the USB plug and weld two wires on it.
Plug in the USB and pass the wire through the gap at the end of the battery insertion; press-
Install the battery in place.
It can be charged while connected to lasword, so you can stick it in place with hot glue if you want.
Please note that there is a flashlight at the end of the rechargeable battery.
I didn't notice this when I bought it, but I kept its function by cutting
Go out and get the camera.
It can be operated by pressing the on switch twice.
It's convenient when you need to refill the fog machine and it's dark!
Wire the fan through the proper hole. Glue (or screw)
Fans enter their housing and be careful to let them go the right way (
Cage on one side where the air is blown out).
I used the E6000 and stuck the two parts together with rubber bands for the night.
Connect the red battery wire to the green switch wire.
Connect all the remaining red wires together and connect to the red switch wires (
I do this by adding the wires together in turn, two or three at a time, and reinforcing each wire with thin copper cleaned out of the scrap wires.
I used a chisel tip on the soldering iron to heat up the whole thing).
Connect all the black and blue wires together (
Blue of laser and switch, Black of fan).
Reinforce all joints with heatshrink tubing.
Test as you move forward.
Once everything is OK, tape all the wires down safely.
I used electronic tape, then black tape.
This step requires some patience.
You're trying to point all 12 lasers to the same place, about 3 '(1 m)
Stay away from the laser array. Use a 0.
5 "Alan key and thin
Don't tighten too much!
The laser rotates on the triangular wedge of the plastic, and both the laser and the wedge can be crushed.
Use a screwdriver to make sure the laser is straight and then align along the diameter using the fixing screw.
At the heart of the laser sword is a portable battery-powered fog machine. I made a proof-of-
This is a prototype of principle before moving forward with the final version.
Basically, you just need a small fan to blow (or suck)
Air is passed by e-cigarettes installed in a 3D printed enclosure.
But I don't need a fine stream for the laser sword-
I want a broad column.
So I put the fan on top of the mouthpiece and guided the fog through 12 holes, one hole per laser.
I also wanted a more powerful stream, so I used two fans: one to blow into the e-cigarette and one to pump out the fog.
Electronic cigarette just Press-
Put into the shell.
It is controlled by its own mechanism: you open it (
Press five times in a row quickly)
, Then press and hold the button for up to 10 seconds to produce a mist feather.
Set the power to a higher power to deal with the greater fog.
I usually set mine to about 25-30 W (
Up to 80 W).
The laser sword needs a specific sequence to operate, as does the childsafe. 1.
Press the battery button once.
The blue light will light up. 2.
Press the big silver button once.
The red LED will light up and the fan and laser will turn on. 3.
Press the electronic cigarette button 5 times quickly.
You're ready to go!
When you want the beam to be visible (
Of course, if you point 12 laser points to anywhere outside the sky, they are always visible)
, Press the big button on the electronic cigarette.
It is foreseeable that in the dark it is most effective when it is relatively static (
But, even with the wind, the "burning dagger" effect is cool.
