So you have decided to take the final step to embracing the force. Does your path follow the Light or the Dark side? (I hear the dark side has cookies).

What ever side you are on, what follows is how to make a Duel-Worthy Lightsabre. That means, you should be able to wield this sword and bash it against things and other lightsabers with little fear of actually breaking the lightsaber. You may end up breaking other things, but the lightsaber will remain intact.*

Total cost of this project is $60 to $1,000 USD. The wide range in cost all depends of how crazy you get with your design. The cost of lightsaber I built for this instructable is about $160.

These were my past creations and experiments.

I sold the lathe

Step 2: Parts and tools

You need PARTS.

Go to your local hardware store and buy parts (some parts will not be available at your local hardware store and must be special ordered). If you have a local Surplus Electronics Recycling store near you (Weirdstuff, Electronics Goldmine), go there and rummage around at the old electronics. Gather anything that looks "cool", geeky, futuristic, funky, hi-tech, or would seem useful later on.

Go to The Custom Saber Shop to buy specialty parts:

OR Ultrasabers

Also go to

If the parts do not make sense now, don't worry, I will explain each section of the lightsaber in detail in the steps to follow.

The Blade:
1 x 30-36 inch long Polycarbonate (pc) tube, thick wall 1 inch outside diameter (OD). Wall thickness should be 1/8 inch. This is the blade.
1 x end cap for the pc tube (blade tip)
1 x blade film ("corbin" film is great)
1 x reflective material with a diameter smaller than the inner diameter of the PC tube.

The Hilt:
1 x blade/LED holder (aka the emitter)
1 x 1.5 inch chrome sink tube. 12 inch long
1 or 2 x sink tube adapter. 1 to attach the blade holder to sink tube and 2 if you have opted for a machined pommel.
1 x switch or button
1 x pomel or end cap

What ever else parts you want to attach to the hilt body - grooved section, plates, gold trim, jewels, tapered section, leather. BE IMAGINATIVE. MAKE IT DISTINCTIVELY YOUR OWN.

The Electronic Guts:
1 x High power LED (luxeon III, K2, V, Rebel; seoul P4, or any LED with a lumen output above 60). Decide if you want to buy an LED emitting a certain color or a white LED and use color filters. The lightsaber I built for this instructable in theory should be pumping out over 300 lumen... In theory. You will see later how I accomplished this.

1 x compatible optical lense to focus the LED to 10 degrees or less.

1 x method to control the current going into the LED - for the example a BuckPuck was used. A Resistor can be used but that method is less efficient.

Sound: Optional, but without it you just have a stick that lights up. At the very least consider pulling the board out of a Hasbro toy.

Batteries, battery holder, speakers, sound board, lots of screws, vibration motor, crystal chamber, and wires.

Solder iron 45 watt or higher and some good quality solder.
Hack saw
Rotary tool (Dremel) with sanding drum, cut-off wheels, grinding and shaping tools.
Drill and drill bits
Jeweler's files
a screw tap set
screw drivers
allen wrenches
Glue for metal or epoxy
Elmers glue
Graph paper
Sand paper, course and fine assortment

Step 3: Make Plans

First thing is to consider what your lightsaber will look like. What color blade" how long is the blade? how long is the hilt? do you want it to look intricate or just a plain chrome flashlight? Where do you want to place the buttons or switch?

To help you out use this useful tool called the Modular Hilt System (MHS) Builder: http://www.thecustomsabershop.com/mhsbuilder/ 

Not only is it great in helping you visualize your concept, it also will provide you with a parts list. Below is an example of a hilt created in MHS Builder.

Step 4: The Blade

The blade is made out of four (4) parts;
the polycarbonate(pc) tube
an end cap (blade tip)
a small reflective disk
a light diffusion film.

You can build the blade yourself

Or you can order the blade pre-made from TCSS:
Or you can order a premade blade from Ultrasabers:

Details on each part:
The PC tube should be 1" OD with a wall thickness of 1/8" and CLEAR. It should be 30-36 inches long. Longer than that and the blade is harder to use and does not light up evenly.

The end cap and the reflective disk go on the end of the PC tube. I use an adhesive backed foil for the reflective disk with a small hole cut out the center. I then stick that to the bottom of the end cap and glue the end cap to the PC tube. You can also buy a small bag of assorted round mirrors at your local hobby shop. The only issue with using a glass mirror is that you are using a GLASS mirror inside your dueling blade. The end cap with reflective material does two things; give you a rounded end for your blade and reflect some of the light back down the blade to make it brighter.

The diffusing film I use is "Corbin" film. This is named after Corbin Das, the username of the person who perfected the use of diffusion film. Without this film the clear pc tube will just let the light inside pass through and will not look bright. The film reflects and spreads the light for a bright even blade. Role the film into a tube that is the same length as the PC tube and slide the film inside the PC tube. The film will then unfurl a little and press against the inside wall of the PC tube. Static cling will hold the film in place inside the PC tube.
Corbin Film is purchased from TCSS.  Item description:

"The special refractive qualities of this blade film are such that they produce the optical illusion of a central beam of light within the blade when illuminated. This "core" is surrounded by a more colorful "aura" that appears to taper towards the tip." -TCSS

On purchasing corbin film, you specify your blade diameter and wall thinkness. Then you specify if you want one layer, two layers, or four layers of Corbin film. I used 2 layers on the green lightsaber in the video. TCSS sent me enough film to cover a blade 40 inches long. I trimmed the length to fit my 34" blade.

NOTE: when rolling the film, make the area as lint and dust FREE as possible.

Ultrasaber also sells a white polycarbonate blade. No blade film needed!

Step 5: The Blade Holder

The blade holder is the emitter section of your lightsaber hilt - the business end. It can be made into various styles and shape but it needs to have a hole in it for the blade to go into. It serves three purposes:
1. It holds the blade securely.
2. It holds and aligns the LED and the Optics under the blade to light it up.
3. It is the heatsink that prevents our LED from burning out.

Choose from the different styles on this page:
Mine is LED Blade holder style #3 with a stack of rubber o-rings and part of the sink tube overlaid on it.

A small hole needs to be drilled in a spot somewhere in the middle. That hole then needs to be tapped to accept a machine screw. A screw then needs to be put into that hole so the end just barely juts out the inside wall of the blade holder. This screw is the blade retention screw. Now when making a blade retention screw you want it small and inconspicuous. OR you want it to blend in with the rest of your hilt design. Thumb screws work well in blending in with the design. a small 6-32 screw works well for being inconspicuous. On my example, the blade retention screw was incorporated into the brass accents decorating the hilt.

Step 6: The Hilt Body

This makes up the bulk of your hilt. Not only is this the place where you can add a lot of personal style but this is also where most of the internal parts reside. How roomy or cramped this area is really depends on  how long the main body is and if you use machined aluminum parts or a chrome sink tube.

The main body can be a single aluminum tube chosen from here (mhs main body):
These are 7 inches long and just under 1.5" in diameter. They are machined and have female threads on the ends to allow the attachment of other MHS parts like the blade holder, pommel, and extensions. They also fit perfectly inside a chrome sink pipe. There is a predrilled hole for a switch. This provides the second most roomy internal space for electronics.

Or combination of the above and parts from here (mhs extensions):
Extensions could be plain, milled, slotted, ribbed or taper to a narrower outer diameter (choke). They add length and design elements to your hilt. It could provide you with the extra space for more batteries or give your hilt a completely different look and feel. If you really wanted to, you can build the entire hilt body out of several extensions. Internal space however is very limited on these parts. Some extensions barely have enough space inside to pass wires through. Something to keep in mind. Like the Main body, these are perfectly sized to slip inside a chrome sink pipe.

Or combination of a Chrome Sink Tube and this piece (mhs sink tube adapter):
The sink tube can serve two purposes. It can server as the main body tube Or it can serve as a sleeve/overlay that slips over your MHS parts. Using a sink pipe as the main body tube provides the greatest amount of space inside since the pipe diameter is 1.5" and the walls are much thinner than the machined aluminum MHS main body or MHS extensions. Using this method, you will have a main body tube that is smooth chrome that you can add design elements to like screws, jewels, leather strips, grips, cut holes and slots into. Just use your imagination.

OR The sink pipe can serve as an overlay - a sleeve - over the aluminum body tube and extensions purchased from TCSS. You can build your hilt using the MHS main body and extensions above and then cut and shape your chrome sink tube to slip over hilt to add additional depth and design. The contrast between aluminum and polished chrome is also quite amazing.

An endless combination of cuts, slots, extensions and main body combinations are available to you when all three components above are used. All you need is a dremel, some files, a drill and some screws.

OR you can shape your sink tube to serve as BOTH a main body and an overlay. To do this, take your 12" sink tube and select a portion that will be cut and shaped into a design and leave the rest intact. This is the method used for the example lightsaber in the video. For the hilt I used for this instructable, I used a combination of 1 extension, 2 sink tube adapters and 1 sink tube I cut into a design I wanted. The sink pipe acts partially as a body tube and partly as an overlay.

So the next step is to show you how to cut the sink tube into your own personal design.

Step 7: Cutting the chrome sink tube

Cut your sink tube to the desired length. Next get your graph paper. Cut out a section big enough to wrap around the sink tube with maybe a 1/8" overlap.

Now remove the paper and draw your cut out design.

when you are happy with your design wrap the paper back onto the tube and check for fit and aesthetics. Looks good?

Take the paper off again and put a thin layer of elmers glue all over the sink tube. Stick your graph paper back on. Wait for the glue to dry.

Once the glue is dry get out the Dremel and cut-off wheel.

CAREFULLY cut away the unwanted metal from the sink tube. DO NOT cut directly on the drawing lines you made on the paper. Cut maybe 1/8" of an inch from it. A vise or a pipe clamp really helps during this process.

Once the design has been roughly cut out, switch to your sanding drum and grinding bits. SLOWLY and CAREFULLY grind away closer and closer to the drawing lines. Remember, you can always take a little more off, BUT if you cut or grind too much you can not put it back on.

For intricate areas of your design use the metal files to carefully take off metal. Sand the edges with course sand paper to remove burs (metal splinters hurt a lot).

Sand the edges with fine sand paper to round out the edges so you don't cut yourself. When you are satisfied with your work, remove the paper and wash the tube with warm soap water.

Step 8: Intergrating the MHS with the sink tube

Now you have a sink tube that does not look like it should be connected to the bathroom sink anymore. You should have something that looks like a work of art, or at least a piece of machinery.

Take your Sink Tube Adapter(s) and slide it inside the sink tube with the threaded section facing towards the edge of the sink tube. With your sharpie pen, mark the sink tube with dots in the locations where the screw holes are going to be.

Remove the sink tube adapter. Drill holes a little larger than the screw being used in the sink tube.

The sink tube adapter comes predilled and tapped for 10-32 machine screws. All we need is two holes on the sink tube to secure the adapter to the sink tube.

Put the adapter back in the sink tube and secure with the screws.

Test fit the hilt parts.

Video of the hilt put together but no electronics yet (except for Crystal Chamber LEDs):

Collect random parts. Keep them in a bin. Go get some thumb screws, LED bezels, leather studs/spikes, machines screws, etc. What ever you can think of to dress up your hilt body.

Step 9: The Electronic Guts

How bright do you want it? Do you want sound? How about some extra stuff like fake electronics, a crystal, feedback motor, or accent LEDs? This is when it could get expensive.

Lets break it down in the next few steps:
* Basic with NO sound
* Basic with advanced LED control
* Basic with Sound
* Mid Level (with sound)
* High Level (with sound)
* Premium (with customizable sound and MP3 Player!)

For my example I went with THREE (3!!!!) Rebels mounted on one Star as close as possible. All are green. This was purchased from Xwingband who has made an investment to be able to produce these custom mounted Rebel LEDs. Powered by one buck puck and three Li-Ion batteries. Each Rebel I think puts out 130 lumen at 700 mAmp. I have three so i think I am over 300 Lumen. More lumen equals brighter blade. i have been told my blade hurts the eyes when you look at it too long.

A fourth Li-Ion battery is used to power the sound board and accent lights. The sound is from a 616 board. There is a crystal chamber, and a feedback motor.

Here is what the functioning electronics look like outside the hilt:

Try to get as much technical specs on the LED you want to use. A good example to start is here: http://www.philipslumileds.com/products/luxeonk2

Read the Datasheet. Important things to know about the LEDS are:
1. Minimum, normal, maximum Forward voltage.
2. Minimum, normal, and max Amperage
3. Light output in lumens at min, normal and max amperage
4. thermal management requirements
5. Size and mounting methods.

Note that white, blue, and green take a higher forward voltage than red, yellow and amber.
Also note that LEDs respond more to current than to voltage. Feeding your LED with current (milliamps) as close to what the datasheet states will provide the most optimal performance.

Picture 1 shows my 3 REBELS mounted on one STAR. Besides the challenge of how to power these beast up was having a solution for the optics. Xwingband provided the solution by mounting the LED emitters as close as possible to each other and providing a collimator with a large enough opening underneath to ALMOST encompass all 3 Rebels.

Picture 2 and 3 shows how the lense (collimator) would normally fit on top of a star with 1 LED emitter. Not shown is the Optics Holder which keeps the lense centered.

Step 10: Electronics - Basic Lightsaber, NO sound

Basic - No Sound.

For the High Power LED we have: Luxeon Star in III, K2, V, and Rebel; Cree; Seoul.
There are others but I leave it to you to do the research. Which ever LED you choose, you have to make sure that there is OPTICS available for it that it will fit in the very small space we have inside the blade holder.

For the basic lightsaber with NO sound we will need the high power LED(s), Optics, batteries, a resistor or a buck puck, battery holder and a switch.

That's it. Easy. And this method leaves lots of space inside the hilt. Space that can be used for a larger battery capacity or more voltage. If you want to have an INSANELY bright bright lightsaber, this would be the best way to achieve it. "Class III laser warning" bright = higher voltage and amperage reqirements. Plus there is heat management to take care of, i.e. larger heatsink. Not having sound and a speaker means more room for batteries and a larger heatsink.

You also have to find the right kind of Switch. For the basic no sound lightsaber you will need a switch that must be pressed/flipped/moved to turn it on and pressed/flipped/moved again to turn it off. This can be a slider, toggle, push on/push off, or latching switch. You must consider the size, mounting hole requirements, voltage and amp rating and look of the switch.

About Battery Choices:
A standard 9 volt battery is not going to cut it.  You need something with decent capacity (measured in mAh - milliamp hours) and voltage. The best choice would be rechargeables.
-- Three AA NiMH is a good choice for powering a single LED. The mAh of most rechargeable AA battery is above 2000.
-- The next choice is a battery pack for RC remotes and airsoft guns. These also tends to be NiMH technology and can be purchased in different mAh/voltage/size configurations. Using a battery pack means you can install a recharge port on your lightsaber and just plug your saber to a charger to be recharged.
-- The newest technology is Lithium Ion (Li-Ion). Li-Ion batteries pack a lot energy density in a small space, that means that 1 AA size Li-Ion battery puts out the same voltage as 3 NiHM AA connected in series (3.6v). So you can get away with buying ONE battery to power 1 LED. This makes wiring much simpler and saves on space. The thing to note about Li-Ion battery is that they are VERY sensitive to overcharging and discharging. Overcharge a Li-Ion and they tend to EXPLODE into a fireball. Overdischarge a Li-Ion battery and it will not ever charge again. There are special chargers and protections circuits used to prevent both cases. Often times the circuit is built into the battery. Li-Ion battery sizes are designated by their diameter and lenght in millimeters. So a size 16340 means the battery is 16mm in diameter and 34mm long (remove one trailing zero - thanks for catching that Dr. dB). A 14500 is equal in size to a AA battery (14mm x 50mm).

Current Control:
To control the current going into the LED we have two methods. 1) Have a resistor between the LED and the battery. 2) Use a Buck Puck.

If you go the RESISTOR current limiting method, you must calculate the correct resistance needed to limit the current going into the LED. Get this wrong and you either get weak light or a fried LED.

Go to this site to calculate the correct resistance:

If you go the BUCKPUCK method, then you just need to purchase the buckpuck that comes closest to the mA of your LED. Buckpucks come in 350mA, 700mA, and 1000 mA. The 350 is hardly ever used in our hobby. Again, look at the typical mA of your chosen LED and match it as close to one of the buckpucks above.

The higher level lightsabers build on the principals on this page of LED, current limitter, switch, and battery.

Step 11: Enhanced Basic - LED Control Board

A step up to just light with no sound is having a Controller Board provide the power to the high power LED. http://www.thecustomsabershop.com/Luxeon-3w-driver-V2-P230.aspx

This board was also an innovation of Corbin Das.

Brief description:
* the board ramps the light up for ON and ramps down for OFF.
* Shimmer effect * Flash on clash and flash on lock up.
* can handle input voltage up to 30v
* can be configured for Momentary or Latching switches
* can be integrated into a sound board (hasbro or MR).

What does all of the above mean? Well, it adds some flexibility in our design. We can use different high power LEDs, different types of switches, different voltages. We can even configure the look/feel of the light being emitted. There are also options to connect this to a sound board.

Step 12: Basic with Basic Sound

For the budget minded, you can purchase a plastic lightsaber toy (with sound) at your local big store (wal****, Tar***, ToysR**, etc). gut it and use it to power the LED and provide sound.

Here is an example of the Hasbro toy electronics powering an Red/Blue/Green (RGB) LED.
The purple blade lightsaber is using the hasbro toy sound board in this video:

How did I get purple? Well, I put 4.8 volts through the soundboard and split the positive wire going into the LEDs - one wire to the Blue LED and the other wire into a resistor then to the Red LED (remember, Red needs less voltage than Blue, hense the resistor). Both LEDs use a common Negative wire. Green was not used. Blue+Red = Purple.

See Picture 2 on how to wire a Hasbro toy circuit board.

Step 13: Mid Level - Force FX Based

For higher sound quality and better light control, people have stripped the electronics out of Force FX Lightsaber previously produced by Master Replicas (MR). MR lost the license to the Star Wars brand but the Force FX product line was picked up by Hasbro.

The most popular sound board to use is the one in the now discontinued product called The Force FX Lightsaber Construction Set - AKA, the 616 or "Joe Jedi". This was sold exclusively at Radio Shack. Why this one? Well with a flick of a switch you can go from lightsaber sounds based on Jedi to Sith (yes, there is a difference). Heck, the set gives you the ability to switch the blade color from Red to Green to Blue. They only place I know to get them now is Ebay. I got two refurbished ones for $40 each.

The MR sound board can only handle 6 volts MAX. Any more and you fry it. The board requires a latching switch similar to the one used for the Basic lightsaber. Using this board to power the LED will limit your choices of high powered LED. Basically if your LED choice requires a forward voltage of more than 6 volts, this board can not do it alone (example would be the Luxeon V , or multiple LEDs like I did).

This is the board that I used. Huh?? I know... I just said that this board can not handle over 6 volts. And my 3 Rebels in series would need 9.45 volts. In fact, the voltage put out by my three Li-Ion batteries is at 10.8v. How did that work?

Well with some applied electronics you can regulate the power going into the board and have the board just provide sound. Then have the rest of the electricity go into a buckpuck. That way you can have the MR board getting less than 6 volts and the LED getting what ever it requires (7.2, 10.6, 12 volt what ever).

Another method is to use a double pole/double throw switch and have two battery packs. One battery pack with low voltage to the MR board and another battery pack with higher voltage going to the buckpuck/resistor/led. Press the button and two different voltages are sent to two circuits isolated from each other.  This is the route I went with.

Step 14: High Level - Ultra Sound Board

Hardcore lightsaber makers are busy making other sound board solutions in the mid-to-high price range.

Ultra Sound Board 2.5 is currently available and more people are developing new boards. If the trend continues, soon there will be several to choose from.

The Ultra Sound Board is found here:

It is also sold by TCSS.

Brief description:
* the board supports most of the available high powered LED
* Has an overdrive function to send extra amps to the LED
* Supports multiple low power accent LED.
* Has multiple Sound Options
* Supports an auxilary button for clash lock and blaster block.

Wiring of this board is very customizable and feature rich. The maker of the board provides instructions on how to wire it all up. As mentioned earlier the Ultrasaber website also sells completed blades (or complete hilts if you don't want to build your own).

Step 15: Premium - Erv's Crystal Focus

Well, if you have the money and the luck, Then the Crystal Focus is the way to go.

The Crystal Focus can be pruchased from here:

Follow the link to the "Electronic Modules". Just to warn you, these boards are pricey and they are very limited in quatity. Erv sells them in batches of about 80 boards and they sell out in about 5 minutes. He is currently on version 4.x.

To give you an idea what this board can do here is a link to the Crystal Fucus 3.0 Manual http://www.mediafire.com/file/hznmeummyyn/CrystalFocusSaberCoreV3.0-GB.pdf
(I put the file on a different website so as not to overload Erv's website).

A brief description:
* The CF can handle different types of high lumen LEDs. In addition it can provide power to multiple low power accent LED and make them blink in different ways.
* The main LED can be controled to gradually power up, gradually power down, shimmer, and flash on clash.
* Auxillary buttons can be used to add extra functions like blaster blocking, and lightsaber clash locks.

* The true power of the CF is the customizable sound "FONTS". Basically, you can create or download your own unique lightsaber sound. The master mixer of lightsaber sound fonts is NOVASTAR. Here is a link to his YouTube Channel to see the many things he can do with lightsaber sound fonts: http://www.youtube.com/user/greytale.

* The Crystal Focus CAN PLAY MUSIC. ANY music. Just copy it to the SD card.

The sound fonts are stored on an SD card. Thats right, the board has an SD card slot. I will not go into how to wire the Crystal Focus. The instruction manual Erv Plecter provides does a great job with that already. Download the PDF above if you really want to know how it all works.

Step 16: Final Assembly

Well, by now you should have a really fancy metal tube between 10" to 15" long. Perhaps 20" to 22" if you decided you wanted a Darth Maul type of lightsaber. The most common length tends to hover around 11.5".

You also have a plastic "blade".

And last but not least a pile of electronics parts - LED, circuit board, puck, battery, switch, speaker, low power LED.

Ohh, and wire. A spool of it. preferably two colors.

Well, lay them all out on your work table like the picture above and measure out your wires. Remember that space is a premium inside these hilts and a little extra wire here and there tends to eat up all that space.

Where it makes sense, go ahead and solder up parts and wires together.

When it does not make sense to have parts permanently soldered together, use corresponding male and female connectors. Use as small a connector as you can find. I used male and female Header Pins like these:

~~~~~~~~~TEST IT FIRST!!!~~~~~~~~~~~
While the electronics are OUT of the hilt, connect up all the parts and power it on. Does it light up? Is there sound coming out the speaker? Yes?

Ok, now comes the most frustrating part...

Disconnect the wires that are on connectors. Now cram all that stuff inside the hilt. Each lightsaber is different. The layout of wires, switches, and electronics is as unique as finger prints. So I can not really tell you how to do it. Just cram it all in there one way or another. Sometimes a compromise is needed, or a part needs to be abandoned. Or maybe your lucky and there is tons of room.

Reconnect the wires.

I have built several lightsabers and I can tell you that even though I learn a lot from each build, something I have NEVER had is plenty of room.

NOTE: MHS parts screw into each other. Be mindful that you are not twisting up your wires and breaking solder points as you screw in the parts.

Tightens the screws, bolts, nuts. Put in the blade. Tighten the blade retention screw. Hold your breath and move your finger to the ON switch...


Have fun.

UPDATE 11/20/2010:
I accidentally fried one Li-Ion battery on the lightsaber last Monday (11/16/10). I took it a apart to make sure the rest of the electronics was OK. It is. (I should have taken pictures). Total time to take apart 5 minutes.

On putting it back together, it took me an hour! Keep in mind this is the lightsaber I assembled. I had hemostats holding wires in place while I used a needle nose pliers to manuever the connectors and plug parts together. I had so many wires going every which way that I forgot what goes to what! Thank goodness I thought ahead and color coded everything (all negative wires are black, clash sensor is orange wires, speaker wire is brown, switch wires are yellow, etc)

While working I looked at my wife and asked her "Why do you let me do nutty things like this?!" She just laughed...

It is tricky and it is confusing and it can get frustrating.Just step back, take a deep breath and try again when you have cooled off.

<p>Hi All. I have a 3 month Pro membership I want to give away. First person to reply with a lightsaber picture built using this instructable gets that 3 month pro membership.</p>
<p>I built a saber using a Rebel Star MHSV1 white LED and got some color discs because I was indecisive about the color I wanted my saber to be. However, once I finished all the wiring and tried it out, the light barely reached the end of my blade, and was very dim in daylight because of the color discs I used. I'm planning on scrapping my wiring and re-doing it with a Tri-Cree LED W/W/W from <a href="http://www.thecustomsabershop.com," rel="nofollow"> www.thecustomsabershop.com</a> , but I didn't want the same result. Would a Tr-Cree LED W/W/W be relatively bright (I know, not a very scientific measurement) when using colored discs? Also, would the wiring necessary for the Tri-Cree fit in my hilt? It's 7&quot; long with a 1&quot; diameter.</p><p>Also, your instructable was very helpful when assembling my saber because all the forums I've been on are so complicated. Awesome job! </p><p> and was very dim in daylight. </p>
<p>Hi,</p><p>Thanks for the compliment. I know this instructable is getting old and many improvements and innovations has happened since I first published it. I am glad that people still find it relevant.</p><p>On fitting it all in, since you are having to power three LEDs, battery requirements may change unless you already had a beefy battery in there to begin with. Also, if you run the diodes in series, you may need a buck puck which will take up even more space, unless you are running a sound board that can manage the LEDs power requirements (i'm not sure which one). Too many variables to know for sure, but I think it will be very cramp.</p><p>On brightness, if you manage to drive each LED at around 700 mA, you should be able to get about 630 lumens output. The general rule is that adding 1 color filter cuts the lumen output in half (but it really depends on the color filter used). So a little over 300 lumen output. </p><p>A single Rebel white would have put out about 300 lumen at 1A. Cut that in half with a filter. So I guess with three Cree LEDs you can expect to double your output. I think that is one of the more frustrating aspects of electronics, physics and light, that you have to triple your effort to get a double gain in results. </p>
On your led and tristar did you put the LEDs on the tri star or did they com one it.
<p>I got lucky and someone on the saber forum did a limited run of stars where the solder pads were next to each other so close that I was able to use a collimator designed for a single LED rebel on a star. He reflowed the LED dies on the star for me. limited run, never happened again. sorry. This just illustrates the value of being active in a forum or two.

ok thanks just trying to get ideas before I build one.
<p>hi im just starting out, and I have a few questions about the inner workings.</p><p>I've looked online, but luxeon seems to be out of stock of their main 140lm rebel leds. are their 420lm tri star led's too bright for a lightsaber, and do they require more power? if so, where else can i buy star leds?</p><p>Also, I'm very confused about how to wire a soundboard into the system. I have one of those sound-effects toy lightsabers from hasbro, but it seems that either the speaker or battery pack inside is fried and wont work. I know you gave a diagram on the connections of a hasbro soundboard, but i am still REALLY confused on specifically where i need to wire one thing to another. </p><p>Additionally, i've looked in the comments and have seen multiple posts about having both a lithium-ion rechargeable battery AND a AA or AAA battery case in the same saber. Do you need to have both in order for this to work?</p><p>Finally, do you have any specific way to keep all the parts inside the hilt from banging around when you twirl and swing the finished saber?</p><p>Thanks.</p>
<p>Hi,</p><p>Lots of questions. Many of these questions have probably been answered on the many forum dedicated to lightsaber creation. Places like FX-sabers, thecsutomsabershop, rebellegion, and ultrasabers just to name a few. With the upcoming Star Wars movie(s), these forums have become very active again. Become part of those communities. In addition, i highly recommend that you also learn as much about electronics as time will allow.</p><p>If you are using a hasbro board (that works) and a single High power LED, you can get away with a single power supply. Just run the sound board and the LED in parallel. You probably want to keep your voltage below 5 volts. A single li-ion puts out 3.7 volts, so that should be good. </p><p>For purchasing an LED, I am not affiliated with any store so I cannot tell you when inventory becomes available. I highly recommend that you contact the vendor and find out when they will get more.</p><p>On tri-rebels... Too bright??? no such thing. The green lightsaber I built for this instructable is tri-Rebel. 420 lumens was easily achieved. I found myself in the Grand Canyon one evening without any gear (tent, sleeping bag, flashlight.. weird back story). BUT I had my green lightsaber. I used it to light my way. Kept me from falling off the edge... True story.</p><p>On too much room inside the hilt, banging around and all that. Nope... If you built a lightsaber of the proper diameter and length (no wookie sabers) with sound board, batteries, speaker, switches, charging port, accent LEDS, heatsink, and yards of wire... and you have room in it for the parts to bang around, then you are a very gifted sabersmith.</p>
<p>Ok thanks. I have found a good site that has the parts in stock. However, I am still wondering something. If I choose to use a tri-led, do i have to buy a special optical lense for the lights to fit? If so, where? Also, how much power will i need with a tri-led compared to a single led?</p>
<p>Oh wait forget about that last part. I would need around 9.7 volts for the tri-led.</p>
<p>You will need a special lense. They sell optics for tri-rebel that are same dimensions as single LED lense.</p><p>On wiring it up, you can go series or parallel on the LED. In series, you will need to add up the forward voltage of each diode. That is roughly the voltage you will want out of your power source. If using a resistor to limit the current, a single resistor in series with the LEDs is all you need. In parallel, the diode forward voltage would be the same as a single but each diode needs its own resistor to limit the current. In parallel, you can get away with a single li-ion for example. Of course, there is always the trade-off, which is a shorter operational time since. Plus make sure the battery can put out a lot of current.</p><p>I recommend you google LED resistor calculator. Find a calculator that handles multiple LEDs. This will verify what I am telling you as accurate or not.</p><p>In series you will need three li-ion batteries or 11.1v. In Parallel, you will need a single 3.7v li-ion battery with a high discharge rate and a high mAh. Someone has asked this before and I did some research. The Panasonic 18650 seems to match the required specs.</p>
<p>oh, I don't think you specified the color of your lightsaber build. But based on the voltage you mentioned I am thinking it will either be green, some shade off light blue, or white. It can't be a deep blue or purple because you mentioned lumens and those shades are measured in mW. Red, orange, yellow and amber tends to have a lower forward voltage.</p>
<p>Yeah sorry i didn't mention that. I am planning on using an amber Tri rebel led, which happens to have a specially made narrow optic for it :). One final question: (sorry, i just really need to know all there is to know), with the Li-ion batteries, are you able to use, say, a AA battery holder with them? In other words, just replace a AA setup with some Li-ion batteries and just hook them up to a buckpluck? I would very much like to know how to handle and use these things without making them explode, thank you very much.</p>
<p>li-ion tend to be a little larger if they have a protection circuit. it's what i used and they made the AA battery holder crack. Maybe cut the springs shorter.</p>
<p>So I've pretty much figured out what I have and what i need to do and get. There's just one more thing I'm trying to figure out, and that's the soundboard. Again, for the reason of budget, I am using the board from a hasbro toy, which includes hit and swing detection. </p><p>I've chosen, due to my setup, to run in series, however I don't know how much voltage I can put through the soundboard. </p><p>Since I'm using 4 Li-ion batteries in the same holder, do you know if there is any way to split the power going from the buckpuck to have some go through the soundboard and then to the led and the rest just go directly to the led? Or would that not work?</p>
<p>the sound hasbro board can handle 5v max probably. ideally, you would want to run it at 4.5v since I have fried my fair share of hasbro boards using just 4 AA batteries. </p><p>My suggestion and the cleanest setup would be to make a 5V regulator. All the 5v voltage regulators I have built output around 4.8v for some reason. I can drop the voltage even lower by adding a small 5mm LED on the output side of the regulator. The easiest way to make a 5V voltage reg is to us a L7805 and a couple of capacitors. They don't take up much room and they will regulate your power supply to something the hasbro board can handle. It will also limit the current to around 1.5 A max. If you want to play it even safer, build a 3V regulator using using a L7803. This will limit the current to an even safer 800 mA max. There are plenty of instructables on making both regulators. Split your power source + line two ways - one going to the buck puck, one going to the voltage regulator. Buck puck goes to LED, voltage regulator goes to sound board.</p><p>Learn as much electronics as you can and learn to read the datasheet of the parts you are dealing with. I cannot stress this enough. The buck puck you are using should have a data sheet. It would have told you if it outputs a lower voltage for other uses like microprocessors. Since I don't know what buck puck you are using, i cannot tell you what it can and cannot do. But my GUESS is that no, it will not. But if you want an informed answer on the component you are using, get your answer from the manufacturer who often is nice enough to provide a data sheet on their products.</p><p> I also bring up data sheets because you said you needed 9.7 volts, which made me guess a green, blue, white or purple lightsaber. You then surprised me with &quot;amber&quot; as your blade color. as as I mentioned in my guess of color, Amber, red, and yellow tend to have a lower voltage. If you read the data sheet carefully you will find that the typical amber forward voltage is 2.9v, so your voltage requirements is actually 8.7 volts.</p><p>Something about electronics I have been told many times by &quot;experts&quot; and pass on to you, it is not the voltage that will kill your parts, it the current. If you hook up your sound board in series with your LEDs, it will not be the 16v that will fry it, it will be the 2.1 Amps that surge through it the moment you turn it on that will make it go poof and release the magic smoke.</p><p>Last thing, because this is getting long. Why 4 Li-ion batteries. If you buy the kind that put out 3.6v, that's 14.4v. A fully charged Li-ion is typically above 4v which means at full charge, your power source is 16v. I think that is over-kill. Three Li-ion will get you 10.8v, fully charged more like 12v. I mentioned before that space inside a hilt is a premium. That extra battery is going eat that space. Also, if you're LED needs 8.7v and your hasbro board needs 4.5 v, what do you think happens to all that extra voltage? It gets turned to heat. This is especially true for voltage regulators. Just something else to think about.</p>
<p>Thank you for telling me this. I have chosen a 700mA buckpuck (the one you used) because the LED said maximum mA is 1000. I chose to play it safe so i don't overload the led. However, if you think it would be ok to use 1000, then i might go with that.</p><p>So basically, is this how you think i should wire this? (very rough idea)</p>
<p>ohhh ok I see that now. Thanks for the drawing, im a very visual guy. </p>
Where is good place to get a sound board and crystal focus.
<p>check plecter labs</p>
<p>Can you use the V4 Infinity Edge blade (the one Saberforge makes) in blade holders from the Custom Saber Shop?</p>
<p>According to the blade description &quot;-Thick walled frosted optical grade Polycarbonate tube 36&quot;x1.00&quot;</p><p>And CSS blade holders hold 1&quot; OD blades. So yes, they are a match.</p>
<p>Thankyou! </p>
<p>Can you use a blade holder without a hilt? They're out of stock and looks like that might not change.</p>
<p>yes, you can get an adapter to connect the blade holder to a chrome sink pipe. That is the method I used for the lightsaber build in this instructable. It actually give you more room inside plus you can make your own design on the hilt. I think the part is called a &quot;sink tube adapter&quot;.</p>
<p>Also, what web store you going to? I went to the custom saber shop and they have hilt bodies in stock.</p>
<p>It has always been my childhood dream to construct a lightsaber. I am glad you can help me achieve this dream of mine. I have found all the parts I need online, but I have a few questions that I would love your help answering. Firstly, I am getting a Luxeon Rebel Tri-Star LED from http://www.luxeonstar.com/SinkPAD_c_4699-1-1.html. I found a 20mm Triple Optics For Rebel LEDs, but I do not know what beam I should choose (Narrow, Wide, Medium, or Elliptical). On to my next question: I am planning on getting a Canadian TrustFire Protected 3.7V 900mAh 14500 Lithium Battery with a Nitecore D2 universal smart charger, and was wondering if it was a good choice. And if so, what should I use to encompass the batteries inside of the lightsaber hilt. I was thinking of using a 4AA Battery Holder with a JST connector to hold three of the batteries which power each of the three LEDS, and just to negelect the 4th slot. Thank you so much for your time, I really appreciate it!</p>
<p>Hi,</p><p>On optics, use narrow or medium. I prefer narrow.</p><p>On power supply, a protected lithium battery is a perfect choice. I use the same. As for holding the battery, i use AA battery holders as well. It's a good fit. Are you going to charge the batteries through a charging port? None of my hilts have charging ports, but I think it is a great idea and would be really convenient. I'm hoping to find time to make a new lightsaber for the upcoming Star Wars moving coming out December 18, 2015. If I find the time to make one, i will install a charging port and update this instructable with lots of pictures.</p>
<p>I finally finished my Lightsaber! It is powered by four 1.5v AAA batteries, a 2.7 Ohm 10 Watt resistor, an amber Luxeon Rebel, and PLENTY of wires! I thought you might like to see some pictures! </p>
<p>WOW!!! I mean... WOW!!!</p><p>Great lightsaber. So bright. Is that yellow or amber? What ever color it is, i really like it. Great craftsmanship. Thank you for sharing.</p>
<p>Thanks! It is an Amber rebel. I plan on making a second saber as well! This one will have 3 or 4 white LEDs on a single star. But I can't figure out how to wire the tri-star LEDs. Could you please advise? Thanks again so much for your help, I could have never done it without your aid and inspiration! </p>
<p>My green one is tri-rebel on a star. It is wired in series which means I needed 10 volts. This was the reason why I used a buck puck. I connected 3 li-ion batteries in series which gives just over 12v when fully charged. the buck takes care of voltage and amperage regulation. You don't have to do it that way though, it is also possible to wire them in series and just supply 3.7 volts with a resistor on each led. But you will need a battery that can put out a lot of current that way.</p>
<p>I meant in PARALLEL. Wire three Cree or Rebels in parallel and use one 18650 li-ion to power all three at 3.7 volts with a 1 ohm 1 watt resistor on each LED.</p><p>I'm thinking I need to redo my green lightsaber...</p>
<p>Thanks for all the help and information! I will be using this specific LED from TCSS. http://www.thecustomsabershop.com/Custom-Tri-Cree-LED-P1035.aspx If I am correct, I believe each white LED puts out 266 lumens at 1000mA. When you multiply this by 3 you get 798 lumens. Just below 800! Any recommendations to specifically run this LED (Battery choices, wiring tips, etc.) would be greatly appreciated!</p>
<p>I would wire them in parallel. 1 ohm 1 watt resistor one each LED. According to the LED calculator I found on line that will run each LED at 700 mA. This is important since drawing too much power from the battery may cause it to burst. Three LEDs parallel equals 2100 mA draw on the battery. That should last 1 hour for a good 18650. </p><p>Now, at 700 mA, the LED will be emiting 209 lumen based on the Cree XP datasheet. So, three LEDS would be 627 lumens. that's still dangerously bright to look at directly. </p><p>Here is the datasheet link.</p><p><a href="http://www.cree.com/~/media/Files/Cree/LED%20Components%20and%20Modules/XLamp/Data%20and%20Binning/XLampXPE2.pdf" rel="nofollow">http://www.cree.com/~/media/Files/Cree/LED%20Compo...</a></p>
<p>Is one 3.7v 18650 2600 mAh good enough to power a white tri-cree?</p>
<p>OK, this one will be long...</p><p>I spoke to the head of engineering about this. He has over 3 decades experience in electronics engineering, so i hold him in good authority to know these things. But we can do the math ourselves just to see how it will work.</p><p>I pulled the specs of a 18650 Li-Ion battery from batteryspace.com. One of their generic ones.</p><p>Battery: 3.7 v with a capacity of 2200 mAh, max discharge of 4.3 Amps.</p><p>I then pulled the specs of a neutral white Luxeon Rebel from LEDSupply.com</p><p>One Rebel LED: Forward current of 700 mA, forward voltage of 3.51 volts max.</p><p>In parallel, the three Rebels will draw 2.1 Amps. Compare this to the batteries max of 4.3 Amps and we see that the battery will not explode when you turn the saber on.</p><p>Since the Rebels will be wired in parallel, voltage will be at the LED's forward voltage of 3.51 max, just below the batteries 3.7 v nominal voltage. So again, we are good there.</p><p>Next question is capacity and run time. The battery's nominal capacity is 2200 mAh, which means in one hour the battery can put out 2.2 amps before it is totally drained. It just so happens our three LEDS in parallel will consume 2.1 amps. So your lightsaber can stay continuously ON for 1 hour before the battery is exhausted. </p><p>The head of engineering I consulted confirmed the math above is correct. Basically, it's almost like the 18650 and tri-Rebels were made for each other.</p>
<p>OOPS! i just caught that you said &quot;TRI-CREE&quot;. My mistake. The math still holds IF you current limit the CREE LEDs to 700 mA. Drive the Cree LEDS to it's full 1000 mA and your run time will be about 40 minutes if your lucky.</p>
<p>Hilt dimensions really depends on what you are trying to make, what you have available to you, what you are willing to order, and from where you are planning to order from. The first big question is where are you? - for example, if you are in Europe or Asia, i cannot recommend for you to drop by Home Depot and purchase a 1.5 inch chrome sink tube for $9.97. That advise would not make sense to you. There have been a multitude of websites created that sell ready made lightsaber parts since this Instructable was created six years ago. My go-to place is still The Custom Saber Shop though. There and my local hardware store.</p><p>Other resources include: <a href="http://www.ultrasabers.com/" rel="nofollow">http://www.ultrasabers.com/<br></a><a href="https://www.saberforge.com/" rel="nofollow">https://www.saberforge.com/</a><br><a href="http://www.ledsupply.com/" rel="nofollow">http://www.ledsupply.com/</a></p><p>I am not affiliated with any of the above companies. I may have just purchased something from them in the past or have seen their products somewhere. </p><p>Feel free to ask more questions.</p>
<p>I wanted to congratulate you and ask that diameter, section and tube thickness is asked because I want to buy and have no idea of the diameter measurements and stuff</p>
<p>I have a few questions about this. Firstly, would you recommend having just one LED for the light source or multiple LEDs? And second, where can you purchase the &quot;Corbin film&quot;? </p>
Actually, scratch the Corbin film question, (just looked a second time) but my other question was what exactly is the heat sink used for?
I meant Buck puck not heatsink...
<p>the buck puck is not totally necessary if you are properly match the battery pack, a resistor and the LED. In my application the buck puck is just a more reliable, more stable LED driver since it uses electronics to feed just the right amount of current into the LED compared to a resistor which is passively limiting current. LEDs are very current sensitive. Even if you give the LED the exact voltage it needs, if not enough current, it will be dim or if the voltage is low, but the supply can pump out a lot of current, the LED will fry. The buck puck regulates all of this. </p><p>But again, not necessary. Today's Li-Ion batteries, paired with the latest sound module like the Petit Crouton, Nano Biscotti, Obsidian USB, Prism, Naigon's Igniter, and a proper resistor should prevent your LED from giving up the magic smoke.</p><p>Thanks for the great question.</p><p>Oh, i know you figured out the answer to the original question, BUT...<br>I am a GUY. 1 LED vs multiple LEDs? I only put 3 in mine because that is all I can cram in there. If I can cram a dozen in the hilt, trust me, I would. and my blade would blaze like a green supernova.</p>
<p>Thanks alot for the guide, it was very helpful! Had fun building my first lightsaber and I'm sure there will be more ;)</p>
<p>That looks beautiful. Great workmanship. Truly a work of art.</p>
