Whether it’s expensive tropical fish, delicate reefs, or humble goldfish, you need to keep your aquarium clean for your aquatic pets. dosing pump That’s all.created by Yojoebo Solo According to (Joe Stiff), this small $18 (14 pound) pump project microdoses chemicals to maintain your aquarium.
A pump system is a peristaltic pump that uses mechanical actuation to move liquid through tubing. This pump system is commonly used in medical and scientific applications where accuracy and hygiene are critical. Since the fluid does not pass through the pump (it is massaged through the tube), the tube can be easily replaced and replaced with another fluid. Yojoebosolo uses it to microdosage various chemicals into your aquarium.
The power source for the project is the Raspberry Pi Pico. Based on the lower bill of materials, you can tell it’s a Pico and not a Raspberry Pi Pico W. The details are scattered in a rather lengthy comment section. You can see that a 2-channel relay controls the pump. Only one input, a micro USB port, is visible on the back of the 3D printed case. The relay connects directly to the Pico’s 5V power supply, and the Pico’s GPIO pin controls the open/closed state of the relay contacts.

The case made with a 3D printer is simple but beautiful. It must have been printed on his one of the best 3D printers as it looks pretty. Glitz PLA Emerald Green FilamentThere is a pump on the front of the case, which is secured with a machine screw. Looking inside the case Downloadable 3D model Sliced for the Elegoo Neptune 3 Pro, you can see where the Raspberry Pi Pico can be fixed (left) and where the two channel relays are housed (right).
Is there a use for this project other than making your waterside friends happy? Of course! Watering plants is the most obvious use. A soil moisture sensor reports the conductivity of the soil. The drier the soil, the lower its conductivity. Pico then controls a peristaltic pump to water the plants. If you are not good at gardening, how about a drink? You can also use the same technology to create a robot bartender. A menu can be presented to the user with several pumps linked to different drinks. After choosing your drink, Pico triggers the appropriate pumps to mix your favorite drink.
