Textilo is a simple board in fabric with an oscillator circuit made with a couple of components and a 555 timer. The purpose of this board is to allow people to have a small board ready to use to make some experiment with eTextile.

The components :
5×5 cm Flectron conductive textile http://www.lessemf.com/1212.pdf (Thickness: 0.08mm (3 mil)- Weight: 80 g/m² (about 35% Copper)- Surface Resistivity: 0.05 Ohm/sq. )
5 x 5 Neoprene textile
5 cm fusible glue paper
Mild Adhesive
10 uF polarized capacitor
100 uF polarized capacitor
100 Ohms resistance
NE555 timer IC in DIP (dual inline package)

1. Cut a 5 cm neoprene disc (lasercut it or use a punch or scissors)

2. With a CNC machine (plotter, lasercutter) cut the Flectron circuit with fusible on it after sticking paper tape to it. Here is the source code for the cut https://github.com/WhiteDileckNoise/hardware/blob/master/textilo-master/schematics/textiloBIG.svg . Please credit accordingly, remix & share.

The laser cut that i use i use a preset call balistic nylon (+50% of cutting force)

3. Remove unwanted parts of the circuit (intermediary traces) with tweezers

4. Place the circuit on the neoprene and iron it

5. Solder the 4 components (555 IC, 100 ohms resistance, 10 & 100 microfarads capacitors) according to the schematics at the bottom of this page (available here as wellhttps://github.com/WhiteDileckNoise/hardware/blob/master/textilo-master/schematics/textiloBIG.png )

6. Test by placing a 3v to 15v battery on the PLUS & round pad underneath it, THEN a resistive sensor on the two upper pads (INPUT) and THEN an actuator (8 ohm speaker for instance) on the two lower pads (OUTPUT). dscn4398_22112490459_o 22124920961_6efe271b63_o

7. Connect any sensors and outputs, imagine your creations.
