The next step of the PET(ch)air evolution is going out to the external space: the terrace, patio, the garden. The idea is that they will gain freedom of electricity net by using solar panels to load their tiny batteries, which can handle up to 3hour lighting. It could be done by a simple timer inside of the cube, but we wanted the visitors to play around with them and also to have control over the the cubes from a remote place, so we used wifi access point in order to switch them on and off e.g. from Prague. Now the installations is running in its initial state, the wifi access point in the pavilion could not be properly installed on the roof, but this experiment proved applicability of the concept, together that it was really installed and working one evening in the pavilion. We changed 9 cubes into independent solar rechargeable objects, while preserving their initial functionality. So now two types of lights are positioned inside: IKEA ready made lights with electricity plug and led light stripes with solar panels and remote control.
In the first step of installation we implemented all the electronics inside of one of the bricks an put solar panels into the top layer. The panels are placed vertically, which is not optimal, but that can still catch enough light in order to shine for several hours at night.
