This is a simple project. You do not need prior knowledge of electrónica.La idea is to start with prototypes made easily, so you can familiarize yourself with the techniques, and then, stir in more sophisticated items such projects become more interactive. This article is based on the instructions of
Leah Buechley, a researcher at the University of Colorado (USA).
Following the instructions described here: learn to make your own "electronic garment, using LEDs and other electronic components that will be sewn into the fabric with thread. In this example, we use a shirt like the one pictured.
- A fabric or garment
- thread (This is hard to find, but below you will find links to places where they sell this thread)
-
- Needle Lights: 2 LEDs 2 AA
-
- A battery case for two AA batteries
- clamp pliers tips
-
- network fabric (optional button)
- A plush corduroy cut fine (optional cloth button)
- sewing machine (optional)
- Multimeter or tester (optional)
- electronics soldering and tin (optional)
Electronics Shops: In Buenos Aires - Argentina, there are several places where you can get the items to make your "electronic piece." For example, on Calle Paraná between 100 and 300, there are several houses electronics. Among the businesses that have a variety of stock, Paraná are 180 or Paraná 220. All the elements used are basic and can be obtained in any of these houses electronics. The only element difficult to acquire is the thread that even where it has to be ordered abroad. At the end of this article, leave scored some links where you can order the wire.

several circuits with LEDs
If this is the first time you facing an electronic circuit, seríaprovechoso understand some basic operation of this before starting the project. As an introduction to electricity, you can use a basic book electronics or electricity.
I leave you some links to see the basic concepts of electricity: Direct Current
English. Circuits in general:
Electronics Club - Electricity and the Electron Doctronics - Circuits Doctronics - Circuits LEDs (light emitting diodes) are a special type of lamparita.Un LED lights up when electricity flows through it in the right direction. Typically, LEDs have two metal legs: on the one hand, the positive leg (+), called "anode" and the other, the leg negative (-), called "cathode." In the above figure, you can see the LEDs in one leg is longer than the other. The longest leg corresponds to the anode. I give you some links to understand how the LEDs: LED Diode
Explain: English LEDs. LEDs:

Design
1. Choose a garment or fabric. 2. Circuit designed to display from the garment. Choose the number of LEDs you want to use, and each position or their location on the garment. Choose a location for the power supply.
In this example we will use 4 LEDs. The batteries will be placed near the edge of the garment, in such a way that they can carry the batteries in your pocket. Remember that each LED must reach two seams of wire.
In the next article in this series see how to make buttons on and off the LEDs. For this reason, please leave the site design for position buttons.

garment Right : Wiring diagram
Note: You must plan the circuit so that the legs are connected to the LEDs directly to the batteries. Because using the AA batteries as a power source, you can choose a configuration of LEDs in series (not reached the required voltage), and one should choose a setting of 4 LEDs in parallel (as shown above). 3. Transfer the design onto the fabric using a pencil to areas where they will tela.Delimita LEDs, batteries and buttons (optional to complete in the next article.)
Armed
1. Sew the circuit according to the design drawing. Can be sewn by hand or sewing machine. If you're using a sewing machine, place the coil of wire as you would any sewing thread. Follow the lines drawn, leaving enough room to place the LEDs and other components.
2. LED is now preparing to sew. Using needle nose pliers to create two loops sewn LED, rolling a metal part of the leg on itself (is best understood by seeing the photo.) Leave a mark visible to know which leg (+) of LED. Try not to exert force on the link between the metal leg and the body of the LED to avoid damaging the internal connection.
screwing the leg of the LED for the slot 3. It is time to mount the LEDs. Place the LED so as to leave in the back of the fabric legs. You can pierce the fabric slightly by placing the LED from behind to pass off as the body of the LED on the other side. Another way to mount it can be without having previously twisted legs. Place the LED on the front of the fabric, passing only the legs for the reverse side of fabric and then make the eye with the paw.
must be taken into account properly align the legs in relation to the stitching thread, respecting the (+) and (-).
Left: Turning the LED through the fabric
Right: Method of section 3 to pass the legs and then the eye With a needle and thread are going to attach the grommet done with the leg of the LED and the previous seam. The purpose of this is to achieve a good electrical contact between the seam and the leg of LED to be sewn carefully that achieving a good surface contact between the elements connected.
LED Sewing
seams (knots) of the legs of the LED
Note: The electricity must flow through the LED. If it had been a piece of thread between the leg (+) and (-) of the LED is not lit. After reaching the seam, secure and cover the thread (of the previous connection) using fabric glue. This is an important step to prevent future descosa.
Pasting the seam (node) between the LED and
thread
4. We will now prepare the battery case. Remove the plastic wire insulation of battery case, two to three centimeters. Once the copper is visible, creating a tightening eyelet cable repeatedly. These loops are the ones who sew the fabric and must bear the weight of the batteries. It should be as firmly as possible.

Right: The battery case connector with twisted wires 5. It's time the cable tie holder leaving piles ready grommets. Remember that the red wire connector battery case should go to the seams (+) and negative at the seams (-). Remember to make a good seam to ensure good electrical contact.
6. Add the finishing details. Probably need a patch in the place where the legs of the LEDs so they do not bother to wear the garment.
Shopping
protection for the garment does not hurt
7. It's time to try!. Put the batteries in the battery case. The LEDs should light.
If the LEDs do not light, review this list of possible problems.
- LEDs are sewn so that the (+) and (-) were reversed. Try turning the LEDs.
- Check that there is no short circuit. Check seams with thread to make sure that there is between the (+) and (-) without passing through an LED.
- Check any thread sewing the cut
- Try new batteries
The garment can be washed with mild detergent and air dried.
In the next post I'll put the instructions to build a web button.
