DIY dosing pump, better than Jebao for less than half price.

[fr3n0z]

Hi guys, just to put it out if anyone need it. Not myp roject but i made one and is actually pretty impressive.

I had a jebao 3.4 but for a 10g nano it was not enough precise. I found this project ( https://www.joy-reef.com/en/dosing-pump-diy-part-1-hardware/ ) and made a 3 head doser for 30€ with 1*3mm hose and now is super precise.

Is a wifi pump with free web interface that is really well done. In the tutorial there is all the part list needed and it can go from 30€ for a 3 head up (it all depend on the head you buy), i've used kamoer NKP for like 6€ a piece and to me is enough.

Project is actually used a lot in italy and could not find bad review about it so i did it too...

If you do it, remember to tip the designer if you find it usefull.

Thank you for your support my friend,
I did a post a lot of time ago:

Arduino DIY Dosing Pump with blackout alert and containers alert

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...

I am building one of these with 4 heads in a couple weeks.

I planned to follow this guide and interface too.

Now I am definitely pulling the trigger on it.

yeah definetly worth it, just a couple of weeks using it, but really happy till now

Just finally built mine, calibrated it just now to finish off the night, will begin dosing tomorrow.

I know it shouldn't be surprising how acurate it is, but I was super stoked to see it hit all my marks in testing.

What a fun, fairly easy project. I had to buy a solder iron and have never soldered more than a single capacitor at most in the past.

For anyone else, if the electronics seem daunting, give it a shot.

Now I have a ton of spare chips because they are all sold in packs, shockingly cheap things.

Huge thankyou to @joyz76

Now I can stop pouring in a ton of stuff all at once.

My tank is what I like to call a hybrid nano. It’s a 29 x 29 x 25 cube, 90 gallons. It certainly has the properties of a nano and a bigger tank at the same time. I’m going to see if I can scale this up to work for my system and if it would give a price advantage scaled up. Cool project. Thanks for sharing it with us.

it all depend on the head you buy. Also the build price it is dictated by the head. The base hardware it cost not even 10bucks, but the head the can range from 20 for 3head to 250 for 3 head. You can add as many head you want with as much flow you want. It's very adaptable

I went with the IC chip that will allow for more pumps without the extra chips.

I started with 3 pumps, but plan to expand to 6 eventually.

The cost of upgrading wouls only be the cost of the pumps themselves, i only need to make 2 connections to the chips already there, making it a painless upgrade.

The best part about this diy pump is, I don't have to worry about it breaking, i have backup parts for every single components. The only reason I didn't have a dosing pump already is I kept getting scared away by reviews of breakdowns where waranty was a massive pain, or they were totally out of luck and had to buy a new unit. Now, this is an issue I will never have to worry about.

Very cool. I use the same jebao on a im15 and just dilute everything for the doser.
