QR Code Stencil Generator and QR Hobo Codes
Yep, it’s a QR code stencil generator! The F.A.T. Lab is pleased to present QR_STENCILER, a free, fully-automated utility which converts QR codes into vector-based stencil patterns suitable for laser-cutting. Additionally, we present QR_HOBO_CODES, a series of one hundred QR stencil designs which, covertly marked in urban spaces, may be used to warn people about danger or clue them into good situations. The QR_STENCILER and the QR_HOBO_CODES join the Adjustable Pie Chart Stencil in our suite of homebrew "infoviz graffiti" tools for locative and situated information display. ABOUT THIS PROJECTQR codes are a form of two-dimensional barcode which are widely used to convey URLs and other short texts through camera-based smartphones. Closeup of a QR code lasercut in 1/8"-thick fiberboard. Accompanying the QR_STENCILER are the QR_HOBO_CODES (see below), a set of 100 lasercutter-ready QR stencil designs created with the QR_STENCILER software. Examples of 19th- and 20th-Century "hobo signs".
