This an ongoing project to build a laser light saber with a retractable blade,

Step 1: Starting point

A battery powered tape measure! :)  If you extend a tape measure, fold it back on itself, it can be pushed in and out and remain stiff....

<p>PS: no distinct humming sound or the crackling sound struck way back then. Hope you make with the humming &amp; crackling sounds!</p>
<p>Hi, Rog. Cool stuff. I was able to make a light saber using an old car's motorized antenna way back 1991! LED's (green &amp; white mix - where you attached the laser) were used alternately to produce the color hue of Luke's saber. I covered the antenna (glueing the tip) inside the saber's toy that extends when flipped, then glued the other end at the base. It extends &amp; closes faster! I made one for my cousin using red LED's (he wanted to be Darth Vader - since he has the &quot;mask &amp; voice synthesizer). Handles used were old metal flashlights (I needed the switch with the red button), since i'm a penny-pincher, had no work then). Sold our Saber toys at ebay for $50 (Luke's) &amp; $40 (Vader's). Now my son (12 y/o) is into electronics, he wanted me to help him build the same model of Luke's saber. Hope I would have the time to build another (since I'm busy at work). Hope you could build the same &amp; upload the video here. &quot;May the FORCE be with you!&quot;</p>

&quot;Light Sabre&quot; is spelled Light Saber.
Thanks for letting me know....life changing moments like this are so rare.....
they truly are.
Awesome! Now.....it just needs to be finished and 'punk'd'.
that is awesome, did you machine all of it?
Yes, all done from raw materials machined to my own design. I am in the fortunate position of having full workshop facilities at home. <br> <br>I could not survive without a workshop :)
If you've ever read any Larry Niven, He had a far more workable solution (and even before George Lucas's &quot;Star Wars Ep. IV&quot;) to the &quot;lightsabre TM&quot; although not quite as pretty. It basically involved a mono-molecular chain that was extended by a magnetically suspended ball (which I believe was accented in 'safety orange' or some other way so that you knew where your 'blade' was located. It was also sharper than nearly anything. Larry also had adjustable 'flashlight lasers' that are probably closer to modern reality than any other &quot;weapon&quot; in sci-fi. But the best tool/weapon he had envisioned had to be his &quot;digging&quot; tool, which resembled a shotgun and tore apart the molecular bonds of nearly any material, making rather nice big holes in, well, nearly anything.
awsome, it's much better than the lithsabers toys at sale, it's a shame that companies don't look for durable toys
It's a great approach to a &quot;realistic&quot; lightsabre. I'm aware it's a work in progress, but have some questions and suggestions.<br><br>Rather than install a larger and heavier motor for rotation, have you tried increasing the voltage to it so the rotation speed is increased? Perhaps LiPo batteries (smaller, lighter, more power). I ask this because there's a noticeable black &quot;stripe&quot; or strobe effect happening.<br><br>Also same question/comment/critique for the tape measure extension speed. To my eyes it looks a little slow to extend.<br><br>Last question: after you folded back the tape measure for increased rigidity, did you test its resistance to G loading by whipping it about? Like jab, parry slice moves etc? I wonder if it might fold briefly before straightening again.<br><br>I'll be following with interest!

I ask this because there's a noticeable black &quot;stripe&quot; or strobe effect happening.<br> <br> <strong>The rotation speed of the lasers is quite high, the camera struggles with filming it, to the eye it looks much better due to persistance of vision.&nbsp; Speed of rotation is not a problem.</strong><br> <br> Also same question/comment/critique for the tape measure extension speed. To my eyes it looks a little slow to extend.<br> <br> <strong>The tape measure is extended and retracted using a friction drive with a rubber wheel against the tape, I tried increasing the speed but I just got drive slip.&nbsp; I have yet to look to see if I can increase the friction pressure.</strong><br> <br> Last question: after you folded back the tape measure for increased rigidity, did you test its resistance to G loading by whipping it about? Like jab, parry slice moves etc? I wonder if it might fold briefly before straightening again<br> <br> <strong>No, This was never going to be a fighting device, the only thing I knew was that if you&nbsp;extend&nbsp;a tape measure and double it back on itself it is quite rigid.&nbsp; I had seen a motorised version and thought &quot; I wonder if I could make a light sabre out of that :)</strong>
He he - I will stick to my steampunk laser blaster myself thank you! Cool project though!
<em>Oooooooo.......</em><br><br>I am <strong>so</strong> looking forward to the finished product!<br><br>Are you going to polish the markings off the tape?<br><br>Oh! Does it stay rigid when you wave it around and say &quot;zhuum, zhuum&quot;?<br><br>
I am looking at painting the number side black as it is inside the loop and hardly seen. <br> <br>As to the Zhuum Zhuum.... It is not stiff enough for serious waving about but it is sturdy enough that you don't need to treat it with kid gloves.
Instead of painting it black, what would happen if you used reflective paint?<br><br>http://store.newlevelmotorsports.com/nilirepa.html
cool and as usual Rog you make some cool stuff I'm still around too and still playing with my lasers just no time for LPF lately.
Nice to hear from you TJM, I enjoyed being a part of the laser community at a very exciting time and still enjoy building laser related stuff, I just find I need to steer clear of the forums as they took up too much valuable time. <br> <br>Regards rog8811
Rog ! Good to see you are still into lasers after all this time - long time no see, bud ! AWESOME instructible - simply amazing what you do with your mind - I am perpetually impressed with your projects, I had no idea you are on here !! I do so hope you win the contest, this is the most unique lightsabre I htink I have ever seen !
Hi Greg, nice to see that you are still around also! :) <br>I am no longer active on the forums but yes, the ideas keep coming and, if the idea is there, it has to be tried! <br> <br>Thanks for the possitive comments <br> <br>Regards rog8811 <br>
GENIUS!!!!!!!
I was thinking about making a lightsaber using a laser, a beam expander, and a small smoke machine. the only problem piece would be the small smoke machine, but one could easily be built with a battery (or butane for more heat) powered soldering iron, an aquarium pump, and some copper tubing.
whats the difference between a saber and a sabre?<br>
One spelt correctly one spelt wrongly, I know I should have corrected the drawing but at least it gives you something to point out, well done!
awesome, reminds me of a chainsaw light-saber!
awesome now go finish it!!
Great idea. Awesome. I can't wait for this!
This is pure genius
