Hello my fine fellow ganja farmers.

 

im looking for some help with some diy .

 

im looking to build a DIY flood and drain brainpot., to save having to spend 150 odd quid on a built one. Its for a mate who has killed 2 bought ones, and doesn't fancy more loss.

 

Now how hard can it be I asked myself?

very, if you are a electro-tard like myself.

As far as I can see the bought ones probably just consist of a segment or digital 24 hr  timer, 2 float switches, step down transformer ( mobile charger)na small pump and a couple of relays,a solenoid or 2  er maybe....

 

Any one ever built one?

or got a wiring diagram and parts list for a DIY job?

 

so far

 

or fancy helping a brother out?

 

cheers

Here is what im thinking about. 

From the wall socket, a 13A plug into a trailing lead. From trailing lead, plug in phone charger. Use phone charger ends topower small circuit board,  activate relays from float switches, but I don't know how. . and then....god knows...…..

maybe using something like this for relays

You mean like the IWS systems, @bigbadbillybob?

I can kind of see how they work by looking at them and their instructions, but I reckon making one would be a lot more expensive and involve a lot more faffing about than some other setups (and they look like they could flood the house, too ;) )

I could probably put together a diagram similar to the one @Marcus found (although perhaps with just one pump and three float valves) if you like, but I'd go for something simpler if it's an option (space for a reservoir under the pots), and one that can't do any damage even if the pump stays stuck on and everything else fails :)

I would prefer a separate brain pot, not under the level of the pots more like the iws systwm , 

why would it need 3 float switches, would it not just need a hi level for when pots reach full, and a low level in brain to tell pump to stop pumping back to res>/I was thinking 2 pumps, one in the brain pot and 1in the res.

res one to fill brain, and obviously pots, and brain pump to  return nutes to res.

not had a proper look at Marcuss diagram.to be honest, im a bit baked

You could use two, but I'd have three in the brain - One high level to switch off the the fill pump when the brain and the pots are full; one low-level to switch off the drain pump when they're empty; and a backup/fail-safe on the fill pump to reduce the chance of emptying the entire contents of the reservoir all over the floor.

I wouldn't have one in the reservoir.

You could use one pump if you made the fill inlent low-level so that it works under gravity, and you could use a motorized valve or some sort of solenoid-operated thing to open it, but there's maybe not much advantage to be had there.

Here is what im thinking about.

 
That could work :)

The only thing that sticks out is that the board is 24 Volts and a phone charger won't do that, and 24 Volts is pretty unusual for a plug-in adapter so might be difficult to find/pricey.

Maybe look for a 12 Volt version instead and get a cheap mains adapter to run it, and I'll draw it up for you tomorrow :)

If you could find at least one float switch that operates the other way (so it's on when the arm is bent) then you might be able to drain a bit closer to the bottom of the brain/pots.

Well, I said "the only thing", but that's two, and here's a third... The resolution of the timer will determine the minimum flood time, and that one looks like it's 15 minutes, which seems long to me.

The timer doesn't have to be 240 Volt or carry the pump supplies though so you could get a 12 Volt digital panel-mount thing instead if you wanted finer control (and perhaps a better appearence, depending on your taste).

Keep an eye out for the number of switch times they can manage per day though - Most of those seem to say 16, which I suspect means "8 on/off cycles" - That's probably enough, I think, but you may have other plans :)

I will see if I can find something suitable maybe something like this?

I will have a look for one. I know what you mean, the float switch in the down position at the bottom of the bucket will probably take up about 30mm of space, meaning there will always be 30mm of water in the pots, not ideal.

Well, I said "the only thing", but that's two, and here's a third... The resolution of the timer will determine the minimum flood time, and that one looks like it's 15 minutes, which seems long to me.

 

15 minute flood times will be fine. I am planning adding an airstone to each pot so it will turn on when the pump starts to fill and turn off when it starts to drain. because it will be oxygenated, then 15 minutes full will work out ok. I should have said this before

mains adaptor like this maybe
