Help request- cheap, presentable, illuminated lightsabers?

[hammer326]

after thinking about this over night, I thought about maybe a rechargeable batt setup. You can use a single 18650 3.7 volt 2500 mah Li-ion battery, this will power the main LED for a theoretical 2.5 hrs, or a 14500 AA size at 3.7 v 1000 mah for 45 minutes run time,

here is the calculated breakdown:
Calculated resistance: 0.1Ω
Nearest lower 5% resistor: 0.091Ω
Nearest higher 5% resistor: 0.1Ω**
Power dissipated by the resistor: 100 mW
Recommended resistor Wattage: 1/4 W
Power consumed by the LED (PLED): 3.6 W
Total power consumption (PTotal): 3.7 W
Efficiency (PLED/PTotal) x 100 : 97.3 %

with this calculation, again you really do not need a resistor , the LED will consume whatever it needs to run at full power

here is a link to a saber I made a while ago showing that a 20 ma RAINBOW LED can be run off a 1500 ma source driving the main LED at 3 volts ( as I stated above, they only use what they need )

Interesting, very neat job. I too pondered that but am trying to minimize aggravation and am not sure I have the room. The hilt is made of 1" PVC, the absolute maximum amount of room I have to stuff things inside. I decided I'm replacing the 2AAA with the 4AAA pack and going from there, confirmed it should really crank up my output so we'll see how this goes.

As an aside, most sabers made today are made using a pipe (PVC, stainless, or most often 6061 aluminum) with a diameter of 1.5".

It's small enough to fit comfortably in the average hand, yet large enough to allow the driver board, battery pack, and speaker to sit within.

hello again,
good choice , you should get about 30 minutes of a very bright blade and it will drop from there ( hence why I like NiHm or Li-Ion batts).
remember to wire it up with the 3.3 ohm resistor on the + wire to the LED and your good to go

Stay as far away from ultrasabers as possible. They make the worst sabers on the planet. Here is a load of evidence.


The above is a picture of an ultrasabers heatsink and LED removed from one of their sabers. It is covered in HOT GLUE. These LEDs easily melt this glue and blow out, and can even spray the overheated glue out of the emitter because the emitters are not exactly 1" ID. This is not a proper assembly.

Also, their Obsidian soundboard uses STOLEN sounds. Ultrasabers had a contract with someone and they violated it to steal all the sounds.

As well, they use unprotected lithium ion batteries in their sabers, I had one actually explode in front of me from one of their sabers I was repairing. It was like a fire bomb.

Bud, we get the point--saw your other post.
Let's not start bogging down every saber thread with this...please.
Halloween is over, the OP made the sabers and Ultra Sabers were not involved.

Yes, it sucks what they are doing!
But let's keep it in relevant threads.....

Suffice to say, that was quite enlightening and will be staying away from them for the time being, I'm actually glad he posted. though I'm not getting in your way when you say to keep it relevant. Anyway, thanks to everyone for swinging by!
