    Solar T-Shirt

    Neck-stroking wearable for sunny days. The components for this solar driven circuit are integrated in this decorative t-shirt, exploring the possibilities of textile electronics and interaction with the sun.

    >> Solar Necklace T-Shirt Instructable
    >> more on www.KOBAKANT.at

    The circuit and this project were inspired by the Overheadbots. The complete circuit that harvests the energy from a 0,5V 100mA solar cell, storing it in capacitors and then releasing it to drive a motor, is split up into modules and integrated into a t-shirt.

    The circuit is referring to SUNEATER circuit. >>http://www.solarbotics.net/library/circuits/se_t1_fled.html

    The solar cell (which can also be replaced by a 3V button battery) is combined with two capacitors in a necklace that can be attached and detached from the t-shirt via poppers.

    The motor (a force-feedback motor taken from a Playstation controller) is situated on the shoulder, and is also connected via poppers. The force-feedback is removed and replaced with a feather that strokes the neck of the wearer every time it turns full circle.

    The remaining components are soldered together to a cluster (maintaining the correct circuit connections) and sewn to the t-shirt directly. Optionally this module could also be made removable or even encapsulated in resin, making the t-shirt fully machine washable.

    The final part of the circuit are the conductive traces that connect the components in the individual modules. These traces are made by fusing (iron-on) strips of stretchy conductive fabric directly to the t-shirt. The traces can finally be isolated using stretchy fabric glue. This keeps them from coming loose as well as stopping short circuits or otherwise unwanted connections caused by folding of the fabric.
