Really cool project from Jose Alcérreca – thanks for sharing! Check out tons more images here.
Autograph is a machine that produces an image using nails and a single thread. Almost all pieces are 40cmx40cm (16″x16â€ ) and are made with between 2000 and 3000 nails and about 500m of thread on a 50cmx50cm canvas.
The algorithm uses multiple-criteria decision analysis to make the resulting work as similar to the original image as possible. Nails are placed using corner and edge detection algorithms and voronoi diagrams to fill empty areas in a natural and pleasing way.
Placing thread without collisions is achieved with a combination of hardware and software. Every segment is placed at a specific height.
The machine is similar to a 3d-printer or a CNC machine and uses a Raspberry Pi to run the software. It has evolved a lot since the first iteration four years ago which required weeks and a lot of manual labour to complete a job.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
