Badges are available in all styles and sizes, however a badge that draws on a stack of Post-It notes is unquestionably a brand new one. The design makes use of three of the smallest, most cost-effective interest servos moderately out there and has a drawing high quality that creator [Bart Dring] describes as “adorably wiggly”. It began when he determined that the CNC and mechanical design world wanted to be higher represented within the grassroots demo scene that’s the badge world, and a small drawing machine that may very well be cheaply constructed from available parts appeared simply the ticket.

Two arms management the place of a pen, and a 3rd motor lifts the meeting to be able to elevate or decrease the pen to the drawing floor. Gravity does many of the work for pen strain, so the badge must be hanging on a lanyard or on a tabletop to be able to work. An ESP32 utilizing [Bart]’s personal port of Grbl does the work of movement management, and a small stack of Publish-It notes serves as a writing floor. With out the 3D printed elements, [Bart] says the invoice of supplies clocks in someplace below $12.

We’ve seen related designs doing issues like writing out the time with a UV LED, however a compact DrawBot on a badge is unquestionably a brand new twist and the truth that it creates a bodily drawing that may be peeled off the stack additionally units it aside from others within the badgelife scene.
