Camera: Canon 5D MkIII with Tokina 11-16mm lens (the only APS-C lens I know of that will still work on frame). 4-stop ND filter to lengthen exposure. This was a 4 second exposure with yellow sparks from a steel grinder on scrap metal and steel wool in a kitchen whisk spun in a hand drill behind the flag, and white sparks from titanium (from the right). I manually popped the flag with a handheld strobe set to 1/4 power a couple times during the exposure (you can see a couple white rectangles hovering in the air above/left of the flag.

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.
