Over the past several years Oakland-based artist Jesse Houlding has created a variety of incredible kinetic drawing devices using magnets and iron fillings. As a series of magnetic components move in various patterns behind the paper, the iron fillings leave a gradual residue that reveals a visual representation of the magnetic field holding them in place. Houlding says that he is interested in the accumulation of marks, specifically how time is evidenced in artwork and the relationship between process and end-results
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
