Step 5: prepare wire connections

The lights are then joined together in parallel, with one set of flexible wire links between all the (+) leads, and a second set joining the (-) leads.

First, make a chain of wires to connect all the (+) leads. Cut the wires in the lengths you will need, allowing at least 10-20% excess length (more slack may be needed for stretchy fabrics). Strip about 1/4" of the insulation away from each end of each wire and twist them together tightly in pairs, end to end in the order they will be joined to the lights. This step is easier if the spacing between all the lights is uniform. If your light spacing is variable, keep track of where the segments belong as you make them.

Pre-solder the twisted junctions, making a decent sized solder blob adhere to each twist. This step is much easier if you can clamp the twisted junction with a set of helping hands or similar device.

Make a second copy of this chain for the (-) leads.

As noted in the list of materials, it is strongly recommended that you use stranded insulated wire. Solid-core wire does not withstand repeated flexing very well, regardless of wire thickness. If you use non-insulated wire or conductive thread, you will risk short-circuits when the wires move and touch each other.
<p>Thank you so much for showing exactly how you wired the LEDs. So many people just put up the schematic and leave you to your own devices, which, in reality, isn't all that helpful.</p><p>And what an awesome scarf! Can't wait to make some franken-version of this. :)</p>
Congeniuos! Looks good, is working perfectly... BUT: Can you give me a hint where to get this very special faux fur? I have not found anything else which would be appropriate to this project. Thanks A Lot! With best regards, Anna
hi- I'm sorry, I've looked but have never seen that particular fur online. I found that type while shopping in the downtown LA garment district (one of the main places with big rolls visible from the street). -Janet
I just moved to Cali and was thinking about going down to LA to buy some fabric. Any recommendations of stores down there? Thanks! Erin
The corner of 9th St and Maple Ave in downtown LA has a few good fur shops, and there are many other fabric shops in that general area.
Hi Janet, thank you for your answer. I will have a hard time to get an appropiate faux fur for that. I alread planning the scarf to be powerde by a lithium polymer accu which causes some difficulties ... the burst into flames occasionally. When I get a solution working and tested it would be a pleasure for me to provide it to you - such a lipo accu has less weight and much more power. Have a nice evenig - it´s around midnight here right now - and with my best regards, Anna
All the color-changing LEDs I can find have three leads not two. Where did you find the LEDs used in this?
&nbsp;thats epic<br /> <br />
What about resistors? Or at least one resistor to restrict current? You may be able to get a more effective scarf with longer life if you try that out.
For a single-color LED, yes, resistors are a good idea. However for the type with built-in color-changing, they work fine with a direct 4.5V power source. I have some pieces built by this technique that are several years old, and all the LEDs still work.
great repurposing of buttons! i've done some led fabrics and a few buttons would have really helped to keep them aimed properly. thanks for the ingenious idea.
That is both wild and very well done......thank you for this
the RGB blinkers @ ALL ELX actually have more than 1 mode... they will cycle thru a quck-snap (or bump) but with them also cycle thru a xfade mode. I used a bunch of them for my light up santa camp marker @ Burningman 07 bonus points for crashing the microcontroller in them and getting them to 'stick' in a mode or color...
AMAZING thnx for the enormous amount of detail!!! really well put together!
this is katya!! omg i loove your work on this one the leopard... and the lights...and the furriness!! omg i loove it!!!! youre amazing! :D
Awesome job! Nice fur pattern ;)
Great job! I love all the detail you put in here.
This looks great! Very nicely done, and carefully explained.
Awesome! I would so do this if I had that scarf... nice scarf by the way.
