12' - polyethylene tubing
1x tubing connector
6x LED's (or more if you like)
6x 69ohm resistors (calculate for your LED's)
6x LED holders
14'x2 copper wire
1x mini switch
1x AAA battery holder (2xbatteries, 3Volts)
assorted heat shrink
Step 1: Make Your Own Hoop
When making your hoop, there is one modification that needs to be done to the JasonUnbound version: File/cut off the ridges on one side of the tube connector. Cutting off most of the ridges as shown in the pic will allow you to take the tube apart when you need to replace the batteries, but still keep the tube together while hooping.
Step 2: Drill LED Holes
Once you've drilled your holes, run a pair of copper wires through the length of your tube, leaving about 2 feet of extra length. I used a twisted pair scavenged from some old ethernet cables for this.
Step 3: Running Wires Through the Hoop
With the wire pulling tool, fish around in the tube and pull the wiring through the first 1/4" hole. Since this is the end of the wire, pull it all the way out . . . an LED/resistor can be directly soldered to the end (next step). The rest of the wires should be pulled out only a few inches, enough for you to work with.
Once pulled out, cut the positive(+) wire, and stripped a section of the ground (-) wire. Strip both ends of the cut +wire and twist them back together. I didn't want to cut both wires, for fear that they'd accidentally pull back in the tube and cause me wire-fishing stress. The auto-wirestripper shown is one of the handiest tools I've ever bought!
Step 4: Soldering the LED's
Now slip a 1" length of heat shrink tubing over the twisted pair of +wires. The heat shrink should be able to fit over your resistor. I use a clip to hold the heat shrink in place, since it'll start shrinking if it gets too close when you're soldering the lead.
Next, solder the +wires to the other end of the resistor (see pics), and the -wire to the ground lead of the LED. I calculated my resistor value to be 75ohms, but the closest I could find was 69ohm. You may need a different value depanding on your LED's. Here's a quick LED resistor calculator that I used.
Clip the leads, and pull the heat shrink tubing over the entire +wire assembly (LED lead, resistor, +wire) as you don't want your +/- shorting together while hooping!
Step 5: Mount LED's
Then, snap the LED holder into the 1/4" hole you drilled. Now, while making sure the LED holder doesn't pop out, use a small rod (I used an old drill bit) to snap the LED into the LED holder from the back. This is where the hole through the entire hoop comes in handy! You should feel the LED snap into place.
Feel free to test your LED wiring at any time . . . you don't need to wire up the whole circuit before testing!
REPEAT STEPS 3-5 for all the LED's you plan on putting in
Step 6: Wire Switch and Batteries
For the switch hole, I drilled a 3/8" hole, then filed it square with a set of mini-files.
Next wire, the switch (don't forget heat shrink!) and the batteries. The batteries should be wired to original 2ft excess end, out the end of the hoop as shown.
As always, feel free to test as you go! Sucks to wast heat shrink!
Step 7: Finishing Up
The switch should be snug in it's spot, but just to be sure, place some electrical tape around the tabs and hoop to keep the switch from flying out.
