looks sweet! When you are done you can put it next to your boxes of salt and 5 gallons of kalk. lol

Noooooo!  This baby is going live.  I sure prefer peristaltic on the Calcium Reactor!

Looking forward to seeing this in action!  Might even convert me to a peristaltic for my CA reactor if it can be done at a reasonable price 😄

Everything about this project I really like!  They claim it can be built for around 100 bucks, we shall see...  That is a steal though compared to a new masterflex.  Is it as good as masterflex?  Maybe not quite, but so much better than most other DIY reef peristaltic pumps out there.  It's in a class of it's own.

It's not hard to imagine building a dual peristaltic automatic water changer with this platform.  Granted they are not on the same shaft, but being stepper motors they might as well be.  Gotta try that too...

I can see allot of things with the electronics that would be nice to do differently.  Use a nano instead of uno, use oled instead of LCD, simplify wiring with a nano shield etc...

The code builds!  The code runs!

Good sign, just had to grab a few well documented libraries. 

However, still missing key hardware.  I have no encoder, and the wrong stepper driver, but was able to simulate it by blinking the LED and hardcoding the motor pulse.

Good progress for one evening.

couldn't you put them on the same shaft? I know some of those dual pumps just stack heads... but the heads are EXPENSIVE plus the flow rate has to be pretty massive.

You sure could, just get a stepper with a longer shaft or a coupling.   it is intriguing thinking about all the possibilities!

Another interesting idea would be a flow meter on it, so it can shut off if the peristaltic tubing breaks, maybe beep or something (APEX could also monitor and alert, but this is more standalone)....

Update while waiting on parts.

I have been running for a couple of days.  Stepper motor gets pretty hot at 2.0 amps / 12v.

Did some googling, sounds like it is perfectly normal.  Also, apparently they have a 10 year rated life at 8 hours per day.  So I should expect at least a few years out of it running 24x7 at less than full speed.

In the pic you can see it is about 127FDFD78C52-8BE8-4EC5-8FAA-D52EA5A246B5.JPG
