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