Hi guys, I wanted to share with you my Arduino DIY Dosing Pump.I worked on them for some time so i have many versions of it, but the final one is great and can dose with a great precision (0.1 ml).Here a pic of the finale work: Build on Nodemcu, a ESP8266 chip based they are controlled via Web: You can also log all your test results on the website and have graphs You have an alarm when your containers are going out of liquids: And you have alarms on power failure too: You can find all the step by step instruction and the software at: JoyreefFeel free to ask for details, or help.
Hello, I am finally starting up another 10 gallon nano-reef after a couple of years out of the hobby. I am building my own LED system and was hoping to get a couple of knowledgeable/experienced forum members to check off on my design. Specifically, I think my drivers and power supply should be sufficient to handle the load of the LEDs in this configuration, but I would be more comfortable getting another opinion. My hope is that this system can support a bubble tip anemone and SPS corals. Thank you for any help you can offer. There are three "strings" of LEDs, each one controllable by a PWM-dimmable driver. The three drivers are then powered by a single power supply and controlled by an Arduino Uno. Below are links to the components followed a screenshot of the schematic. LEDs Royal blue, blue, and red Violet Neutral Whites Driver LDD-L Series Mean Well Step-Down Mode CC DC-DC LED Drivers ("Wires", 700 mA, 9-36 Vin, 2-32 Vout) Power Supply LRS-150-24 Mean Well LRS Series Enclosed Style Switching Power Supply (24 Vout, 150 W)
Kraken-Tech posted a topic in DIY ProjectsHello and happy holidays! First of all, we're new to the forum... so we're presenting a project we're working on: http://kraken-tech.com/ It's a custom controller and we're working on some points we think are pretty important: -compatibility, we want to support all the common models of aquarium equipment out there (like pumps, sensors, lights, etc.) -modular, we want it to be scalable and configurable. In this way the complexity, costs, size, and other characteristics of the system can be tailored to the user needs. -remote management, we want to control, configure and monitor the system remotely, through a web interface. As you can see from the blog link above, we're already experimenting some versions of the controller, with different configurations, sensors, etc. Let us know what do you think! Also, it would be great if you could tell us what kind and model of pumps you're using in your aquarium. In this way we'll do some research, to plan our compatibility features in that direction. Thanks! Matteo & Francesco
