The Aerographer: Arduino Project #ArduinoMonday

Via CreativeApplications.net

Created by Luiz Zanotello during his ongoing master studies on Digital Media at the University of the Arts Bremen, The Aerographer is an installation that explores the state of uncertainty in times of ubiquitous technological mediation, borders among territories and boundaries among bodies. Designed both a system and an individual, the Aerographer is “trapped on groundless air, seeking to sustain a place inside of the clouds”.

The installation reacts to subtle changes of airflow within a room. Conceived to be mounted temporarily and through serendipity, the installation can adapt to different spaces and situations modularly. Each module contains a fixed center part, and one to three fixed probing parts. Each probing part works as a disassembled hot-wire anemometer, grasping constantly micro changes of temperature between itself and the center to measure airspeed. In between them, a node travels by converting the measured airspeed difference into mechanical linear motion, which shifts retractable bands that can be connected to other nodes. A map unfolds, from a tree-like structure of fixed parts, to a networked kinetic map of differential measurements in motion.

The project was extensively prototyped with Arduino-based basic electronic components, and Processing for visualisation / simulation purposes. PCBs were produced using DIY techniques combining laser cutting on painted copper plates and etching. Installation uses Arduino Uno (stand-alone with an ATmega328p micro controller) and sensing is achieved using custom hot-wire anemometers, developed with inexpensive 1N4148 diodes working as temperature sensors – PCBs to hold the sensor parts. Motion is achieved by stepper motor drivers: DRV 8825 and NEMA 17 stepper motors. The installation includes custom 3D Printed white ABS pulleys and PLA holders, small cases and adaptors and well as custom laser cut cases of white and transparent acrylic plates. Retracting bands were made by grinding metric retracting bands enclosed on a 3d printed case. Finally, standard ball bearings, steel cables, threaded rods, nuts, and aluminum tubes complete the install.

As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email circuitpython2022@adafruit.com to let us know about your post so we can blog it up here.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
