Introduction: Illuminated Bullets

By
About: i'm 35. With 23, i started with a stage in taylorship, did sum time-work, changed to saddleryuntil now, worked in a middle-age-onlineshop. Three years ago, i started mailing; a major part of my friends are jug…

I recognized new followers notifications in my mail inbox and decided to prove myself alive and come up with sumthin i'm actually workin at, so this is just a small gimmick and part of the uniform i'm makin for a jugglin girlfriend (btw i'm also building a new illuminated holder/toolbox for her levi-sticks and i'm planning to publish that sum day).

Tools:
5,5mm drill
drill rig (recommended)
soldering iron
file
cutter/scissors
side cutter
12mm-holepunch (optional)

Mats:
1000μl/1ml pipette cap
.30 bullet casing
5mm-LED
resistor
glue
piece of black(?) cardboard

About materials:
- Those caps are commonly used in chemistry-labs for one-uses. They're put on a pipette to transport a special amount of a lotion from one container to another. After use they're contaminated and thrown away. The caps are sold in packs of 1000 pcs; costs via ebay are about 20-25€. I got my first half pack from the lab of a local company of wastewater plants, wherever one needs continous control of anything that got to do with health and nouridge you find these, so go and ask the peeps, if you don't wanna pay for it.
- Bullet casings can be re-used that's why there's a market for it. I got mine from a guy that own a goth-store producing these bullet-casing-belts. He told me that you got big chances to get that stuff from a firing range, though i guess ppl from imperial states of america won't have any problems to get these anyways
- LEDs: Well, i dunno too much about electronics myself, but my neighbor told me sum useful facts: 1. the voltage of the battery should be at least as high as the voltage of the leds, (amps is just an amount of energy and not very useful for this project). If the voltage is lower than the led, the led will be lesser shiny, if it's bigger you burn out the led - but that's no problem as long as you use a resistor. 2. To know what resistor you need, check the stats of the led (not the battery) and multiply its voltage and amps - this way you get the Watts; the solution is the min of watts you possibly need, lower is unhealthy. For example: i used leds with 3,2V/20mA and a resistor with 0,25W (could've used 0,1W, but bought a bigger one).
3. The pins of leds got two different lengths, plus is the long one, minus the short one. 4. Resistors don't have a minus or plus.

Step 1:

Howto:
1. Use the 5,5mm-drill/drill rig to drill the percussion cap of the bullet casing.
2. Solder the resistor to the minus of the led and cut the overlength with the side cutter.
3. The pipette caps got 4 lines on the big end to stabilize the opening, i cut this part off (this shortens the cap by ~2cms)
4. File around the cap so that it fits into the bullet casing, put sum glue around to make things firm.
5. Put sum glue around the led and put it in the back of the bullet casing.
6. punch out a piece of cardboard, cut it almost into two pieces over the middle.
7. Put again sum glue on the led (this time i used construction glue as it's not transparent and more pasty) and coat over the piece of cardboard

Now if you solder cables to the led's pins you can make yourself a necklace using a coin cell.
I connect it with a special copper conductive thread that i can sew onto fabrics and that i can solder to, but that stuff cost me 110€ for a spool with one kg - though it's awesome thread, i wouldn't recommend you to buy it. Luckily i got it in my own country Germany, it's the 2nd time i buy such a thread and it really thrills my mind, so if you wanna know about it, feel free to contact me.
