The pico wave maker
thingiverse
Here is the original text rewritten in American English with active voice: A Wave Maker Module for Reef-Pi. The Circuit is a Copy of the Doser Module, Which Uses a L293D IC to Control Up to Two Wave Pumps. My Prototype Setup Features Two Ordinary 12V DC Submersible Pumps from Amazon (Under $12). PWM Control is Provided by Reef-Pi 3.0's Arbitrary PWM Profile Capabilities. The Unit is Powered by a 12V 3A Power Adapter, Runs on a Pi 3 Model A with Perma Proto Hat and Nylon Standoffs (M2.5) for Mounting. An LM2596 Converts 12V to 5V for the Pi.
