Autograph: A gallery-worthy nail and thread artwork printer driven by a Raspberry Pi #piday #raspberrypi @Raspberry_Pi
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.

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.
