Great project from Mark Waller! Check it out on YouTube.
I am not sure why I made this. Just a bit of fun during lockdown and to satisfy my natural curiosity!
It’s an opportunity to try to photograph some cool images of airflow in different situations. I am not expecting to make any new discoveries!
I have already found that the slo-mo feature on my smart phone takes interesting shots of the smoke but the best pictures are stills taken with 1/4 or 1/2 second exposures. In these pictures the smoke trails are smoothed into lines which are clearer to see.
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.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
