Digital water wall, Water Fall #piday #raspberrypi @Raspberry_Pi
Didier Briand shared with us a project created by students:
Here is my student’s last year project from Château-Gontier in France, a digital water screen control with a Raspberry Pi and custom Attiny boards. 4 students built it for their Baccalauréat with major in Engineering (saSASage 17), from start to end. The main difficulty was the money, that’s the reason why there’s only twenty servo valves but program in python should pilot hundreds of valves next year 😉
Total cost didn’t exceed 250$ without water pump. (read more here – in French)
The initial objective of this project, led by a group of four students, was to mix art and technology. Exchanges and visits, in close collaboration with their teacher of Philosophy, were conducted around the work of contemporary artists, particularly those of Arnaud Fabre and Pierre Besson.
The selection of students is then focused on the construction of a digital water wall. There are in the market for similar products costing them suitable for the exclusive use of professionals (salons, malls, shows, theme parks, etc.).
They developed a solution for 70h accessible to the general public in terms of cost, implementation and ease of use. The water wall, of a width of one meter, is constituted by a plurality of individually controlled jets 20 through as many valves.
Control of each valve is provided by a series of e-cards developed for this project and coupled to a Raspberry pi. The management software is coded in Python, it provides processing and sending a user-selected picture. It appears in “black and white” on the water wall in the manner of a screen to scroll vertically.
The prototype is built around a modular architecture and only the cost allocated to the project has limited the number of nozzles.
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!
Adafruit has had paid day off for voting for our team for years, if you need help getting that going for your organization, let us know – we can share how and why we did this as well as the good results. Here are some resources for voting by mail, voting in person, and some NY resources for our NY based teams as well. If there are additional resources to add, please let us know – adafruit.com/vote
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.
