Auto PH EC controller Build

[Nanook]

Right you dodgy bunch! I managed to aquire one of these off egay yesterday cheap ( rrp is something mental into the thousands! )



Now... this is a controller without pumps etc and outputs 240V AC - first thoughts were peristaltic pumps.... however on a small grow I can imagine over dosing is easily done. ( I have no idea how refined the controller is, some only allow 5-30mins frequencies - so other than a majorly diluted solution this is not an option )

Second thought.... Hospital IV pump - VERY precise however with a controller kicking in and out, they usually require setup per dose, and have a battery backup so when the controller cuts the feed, it would continue - NO USE!

Third thought - Syringe driver.... swaying towards this tbh, trying to find one that will autostart when power is applied with no manual buttons to be pressed - possibly rewiring a hospital one but I might also need a pot to limit the speed it works at on full voltage!

Anyone got any ideas? Anyone done anything mad like this before?

It's like talking Chinese to me. Got no idea. Like I am listening to Musk speaking about artificial intelligence.. you better get in touch with him mate surely he will sort something out for this situation :laugh:

hahahaha bulls, B.G ( the ugly fecker ) is going to have a word with a mate for me regarding this also - fully automated yo!

What does the unit use as a standard if you bought it as an all in one kit?

gmo its not like that, it plugs into pumps. I want fine controll pumps mate, not 300L/h etc. I can make it control any speed/type of pump

Ahh yea, I get ya. I was just thinking if you knew the standard option you could reverse engineer the specs to meet your requirements

I think its a universal depending on the scale - when I get it I can see how refined you can make it as well, it might do 1 second bursts meaning a bigger pump could be suited etc - I personally want a 1ml/H or similar pump so if it asks for an hour thats all it gets if that makes sense. Over engineered both ends for safety :)

I get what ya mean mate. You almost want just a portion doser with a single dump and refill

The smallest single stage pump I could find was 5v 100l/h pump

I'll need to look into it further really but I'd be looking for something like gravity fed 1ml syringe doser with a servo actuator

Medical syringe drivers do 0.1ml/h but... I'd have to modify one to auto start stop and throttle down as max is like 100l/h
