energy : final pitch

  sol a drawing machine that takes one year to achieve completion For the final project I will build a solar powered system that will use the length of a full year to draw a circle. I wanted to work on a project that was disconnected from the grid and could live almost on its […]

solar challenge : progress

The goal of this solar challenge is to keep it simple and stick to the requirements. In my opinion this is a great way to learn various tools that will be extremely useful in the future. The idea is to log small variations of the Earth’s movement and its atmosphere – I don’t even know […]

Bk VIII:183-235 Daedalus and Icarus

Meanwhile Daedalus, hating Crete, and his long exile, and filled with a desire to stand on his native soil, was imprisoned by the waves. ‘He may thwart our escape by land or sea’ he said ‘but the sky is surely open to us: we will go that way:Minos rules everything but he does not rule […]

Hearing The Grass Grow

Mycelium, the vegetative part of fungus and the fruit of which are mushrooms, form fungal networks that can cover as much as thousands of acres, […]

50ft of self expression : tests

This work consists of a receipt thermal printer constantly printing the waveform of the sound it is producing captured by a microphone that, in the final version, will be inside the printer. For test purposes I kept the microphone out of it. In the beginning I was having some trouble adjusting the space between lines, […]

energy final : tests

I started putting together some components to see how the circuit for the final may look like. To begin, I connected the stepper motor to the EasyDriver and Arduino. At first I thought the easy driver wouldn’t be enough to run my motor (400 steps/rev 3V 1.7A) because it can only output 750mA, but surprisingly […]

the paradox of sisyphus

* The myth to be discussed in this text narrates the story of Sisyphus, the king of Ephyra, who was convicted to roll an immense boulder up to the top of a mountain. As he was approaching the summit, the rock would roll back to its initial point. Thus, Sisyphus didn’t have a choice but […]

kinetic challenge

objective // Generate and/or store energy by converting Kinetic energy (for a maximum of 30 seconds) into electrical energy in order to power a light source for as long as possible. process // For the kinetic challenge I worked alongside Craig Pickard.  Our initial concept focused on the conversion of gravitational potential energy (GPE) to […]
