Parts List Check

[jmannelson]

Hey guys,

I am getting ready to build my first lightsaber for my son as a Christmas present. I would like to get started on it soon, as I don't know how long it will take me to do it, being a noob. Before I order all of the parts I wanted to get some feedback if I have everything I need to get started. Here is what I have sitting in my wish list right now:

White shouldered 1" thick walled blade tip with reflective disc
1" Thick walled Trans White PolyC 40" long (36 inches +$0.50)
1.25" Sink tube LED/Blade holder
8-32 x 1/8" Set screw
8-32 x 1/2" button head screw
1-1/4" x 12" Chrome sink tube
1-1/8" Chrome end cap

Rebel Star LED & MHS Heatsink Module- Deep Red
MWS Short Latching 16mm AV Switch
1ohm 2w resistor
82ohm 1/4w resistor
MWS Pre-Wired Nano Biscotte Sound Module
MHS speaker and 2x AA battery holder
2x Tenergy Li-Ion 14500 Rechargeable AA size 3.7V 800mAh
TrustFire TR-001 All-in-One Charger

Thanks for taking the time to look this over

First off, Welcome to the Forums.

From what I have seen of your list, here's what I see as the "issues":

The NB only takes 3.4V - 5.5V for power, meaning you can only use 1 14500 and a dummy cell, not 2 14500's (though you could buy a second as a spare). Also your resistor calculation looks off for the main LED you would need a 2 Ohm 1 W resistor for a deep red. You also need some type of chassis system (or something) to prevent everything from rattling around within the hilt, since you're using going the sink tube route.

I don't do sink tube sabers, so while your hardware list looks pretty good to me (meaning I don't see anything glaringly wrong with it), I'll wait for SS or some others who have done sink tubes to comment on that part.

Thanks for pointing out the chassis system I hadn't noticed that yet. Could I use the 700 mA buck puck instead of the resistors?

No, you would need the resistor, as a buck puck needs more than 3.7V to work.

Ok gotcha. After reading a little bit more I realize I may need a second momentary switch for the NB, is that correct?

No, you only need one momentary switch.

No, you only need one momentary switch.

I don't need a latching switch for the main LED?

No. Since you are using the NB as a sound board, all you need (all it requires) is 1 momentary switch. You may want to download the manual from the store and go through it carefully

Haha ya that's a good idea. Thank you for all your help, I appreciate it!

Now I may be making a second saber, with the same components (with the changes you noted), except I want this one to have the cyan rebel star. Will that change my battery situation? Will one LiIon 14500 be enough power?
