Sequencer

Un séquenceur simple basé sur un 4017 que je prévois d'utiliser comme un distributeur de courant sur plusieurs circuits, alternativement. Il envoie 1 volt de moins que le courant qui l'alimente (entrée pile 9v = sortie à 8V). J'ai choisi de ne pas mettre de LED pour éliminer les repères visuels et favoriser une "surprise sonore".

Assembling bits of fabric

Preparing the chip to be sewn onto fabric

To me, the 4017 sequencer chip looks like a scorpio like this !!!! psssshshhhhhhhh !!

Sewing zig-zag lines with regular thread

The lines will be used to canalize conductive thread.

Making connections...

Conductive thread is being held in place using the blue zig-zags as 'insulator'.

Sequencer steps : done !

The 10 steps are sewn, ready to proceed with the rest of the circuit.

Preparing the diodes that will be soon at the end of each 'output' step

Little hooks are made with the legs of the diodes, and soldered to ensure durability.
