Ez Robot community I wanted to introduce my latest application of this system. Some members hear already know I keep two salt water aquariums one coral which unfortunately died off and my predator tank. Sea life needs delicate balance maintained in their little ecosystem. Things like light spectrum , temperature, ph balance , current of water , nitrate and ammonia levels and calcium levels. These things take a practiced hand to maintain. I am building a new system and using ez b to monitor salinity, nitrates and ammonia, temp , water current flow and the ph. The ADC ports are useful for these and EZ board can control the current and switching to a backup power supply ( a apc for computers inside the cabinet to keep ezb and pumps powered). Also the ezb can turn on and off night , morning , day , and evening lighting settings. With a custom injection device im designing ezb can provide nutrients , calcium and even medicine if levels are out of wack. I started the build today and I am very excited!
Ok i had to strip the epoxy off because it didnt gel smooth and look as good as I wanted. Bright side is i started installing the filters. I found that I need a male to male 1/2" pt plastic fitting to the canisters as close together as possible.
A fitting this short should allow me to easily fit three canisters side by side. I already attached the mounting hardware to the top of the canisters and somehow I managed to loose one of tje brackets! Seriously? Thats soo frustrating.
Tommorow in my spare time at work I will start designing the servo actuated liquid injection system for the nutrients , buffer and other fluids. I did however find today a machine I can hack to automatically feed my fish pellets. All but two of my fish like pellets so thats a plus!
Since I really only need the mechanism and not the daily timer I can hack it. I will look on ebay for a used on or cheaper model since I am going to hack it anyways.
Ok here is my idea using 4 of ez robots high torque servos connected to 150cc syringes.
If I use live injectables like photo plankton for example the syringe needs to be refrigerated
Maybe you could use a peltier cooler to keep it cool.
Thats a possible idea. I will research them and see if it is a practical option.
Ok I had to custom make fittings called a 1/2" male to male pvc pt (insert name here later) I took two straight to thread adapters and put a 3/4" section of pipe between them. I used weld on 750 hotweld pvc glue.
The goal here is to make connections close together so I could get three canisters in the left half of the stand. Heres a pic showing about 5 inches of play plenty enough to get a 90 degree elbow on the left end
Next step is getting 2 90 degree 1/2 pt ends and 2 ball valves also one at each end.
