README
README.mdripple tank
Ripple tank remote laboratory funded by Royal Academy of Engineering Ingenious grant 2025-26 for high school outreach activities. The ripple tanks automatically maintain water depth by filling from a reservoir and are pre-configured with different setups, including one or two wave sources, various water depths and different optics (reflectors and refractors). The user interface enables control of wave frequency and amplitude and the measurement of wavelength, supporting students to perform in depth investigations of wave properties beyond the typical classroom use of ripple tanks for demonstration and observation of wave behaviours only.

Questions
How big is the Ripple tank pcb PCB?
It measures 100 × 100 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Ripple tank pcb use?
111 parts, built around the AL8860WT, BME280, LM2596S-5.0 and PAM8403. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Ripple tank pcb KiCad files?
From the practable/ripple-tank repository on GitHub, at the commit this page was made from: the board is hw/ripple-tank-pcb/ripple-tank-pcb.kicad_pcb and its schematic hw/ripple-tank-pcb/ripple-tank-pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ripple tank pcb design in my own project?
Its repository publishes it under the AGPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
