Title: DIY Controller (for under £15) Instructions...
Post by: Tom White on January 22, 2015, 06:33:26 pm
I've just made another DIY controller - a spare - for under £15.  These are class, they only require calibration once (the air temperature doesn't affect them), and they don't require a battery in good nick to work either; they'll run on any old 12v battery.  

I've included an on/off LED switch - though I think that's superfluous to requirments; it would work without it and be even simpler to produce.  An LED on/off switch lets me know if it's on at a glance, and it also means I don't have to turn the dial to turn it on (I'm very lazy).

(http://www.cleanitup.co.uk/smf/1421950765_Tosh4.jpg)

Anyway, these are the parts I purchased:

12v LED rocker switch £2.00
http://www.ebay.co.uk/itm/261513977084?_trksid=p2060778.m2749.l2649&var=560391577650&ssPageName=STRK%3AMEBIDX%3AIT

Waterproof Project Box 115*90*55mm £4.52
http://www.ebay.co.uk/itm/201212241692?_trksid=p2060778.m2749.l2649&var=500405437151&ssPageName=STRK%3AMEBIDX%3AIT

10A 12V~40V PWM DC Motor Speed Control Switch Controller Volt Regulator £7.00
http://www.ebay.co.uk/itm/10A-12V-40V-PWM-DC-Motor-Speed-Control-Switch-Controller-Volt-Regulator-Dimmer-/121250426718?pt=UK_BOI_Industrial_Automation_Control_ET&hash=item1c3b16af5e

I drilled the holes for the voltage regulator and the switch and a hole at the rear for the wires that go to the pump and the battery:

(http://www.cleanitup.co.uk/smf/1421950849_Tosh1.jpg)

Then I wired it up; soldering the wires on the switch (first time soldering; which why it looks rough):

(http://www.cleanitup.co.uk/smf/1421951024_Tosh3.jpg)

I was unsure how to solder or wire a rocker switch, but it's all on youtube:

How to wire a rocker switch:
https://www.youtube.com/watch?v=cQpQWFYX524

How to solder:
https://www.youtube.com/watch?v=BLfXXRfRIzY

The wiring on the voltage regulator is easy; on the rear it tells you what's what, with regards motor +- and battery +-.

I quite enjoyed doing it too.

If anyone fancies a bash, don't be shy to ask questions, though it's pretty straightforward.

And if anyone can suggest any improvements, I'm all ears.

Oh, Ionics sell a similar, with VAT and delivery, it's £210.00

(http://www.cleanitup.co.uk/smf/1421951528_Tosh1.jpg)

And it doesn't even have an LED switch on it!  :'( :'(

Looks good mate, good post


When you say only needs calibrating once, how do you calibrate it?
I'm assuming it runs off the pumps pressure switch, so wouldn't need 'calibrating', just a pressure change on the p/s itself?

Impressed Tosh. The only niggle for me is the soldered wires. I would have used a little bit of heat shrink. Doubtful they will ever touch BUT they said the titanic wouldn't sink and seanK wouldn't post 4000 replies on vision.

Thanks; yes, you're right - thanks for clarifying my post.  Just the pump's pressure switch would need calibrating.

For those who don't know, just connect hose reel to pump, and pole to hose reel and turn it on.

At the bottom of your pump (on a Shurflo anyway) there's a hexagonal 'nut' where the arrow is pointing:

(http://www.cleanitup.co.uk/smf/1421952326_Tosh1.jpg)

Just adjust that so the water flows nicely - your normal working flow - yet when you 'dead end' the flow (whichever method you use to stop the flow), the pump shuts down pretty much straight away.

I've only ever had to do this once, unlike my old electronic flow controllers, which made me do it if the temperature changed.

Great info thanks Tosh. The only downside to this setup could be someone running their battery right down and potentially shortening its life. If you charge them daily they should be fine. For an extra pound or two i think it would be enhanced by putting one of these on the box...........
http://www.amazon.co.uk/dp/B008KY5ULW

That way you could make an informed choice not to run your battery below say...11 volts ?

Cheers, Clean, I've just ordered one and I'll add it to the controller I've just made.  The only downside to it is that it's square shaped - it means cutting the box rather than being able to drill through it.

But cutting through it won't be that difficult.

Thanks, top tip.

Never knew that!!

You can waterproof any electrical circuit that doesn't get hot. I can use my trolley system in the pouring rain without worrying about water getting into the pump or the box with the voltage regulator in it and have done for a good few years.

The links for the voltage meter - have just ordered. Thanks.

Off topic, but candle wax is a simple water proofing solution for so many things.

Even red matches (swan vesta's). If you go camping or such like, coat the heads in candle wax and they'll still light even if soaking wet or in the rain.

Tosh, you may remember back that i posted about trying some PWR motor controllers. Ours burnt out the boxes they came with, with hindsight and now looking at the amp rating i realise ours where not up to the job fully. Although they are still fitted and still work !!
 Can you confirm you've had no overheating issues ? I've noted your linked ones are rated to 10 amps, not sure what ours where, but judging by the very thin wires we had i'd guess not ten amps !! I'm oredering my stuff now and hope to make two up for a start. Keep you posted, thanks again. I'll add to this thread once i've made them.

No overheating issues and we've been using ours for (I don't know exactly) 6 to 8 months.

No issues what-so-ever.

One thing to note is that you should only use candles that are waterproof.  If it doesn't say on the packet, ask the vendor if they're the waterproof candle wax ones, or not.

To stop heat building up inside the box especially on hot days just add a small fan for a pc. They're 12v DC, draw almost no current and cost £2 or £3 from maplins.

I cut a hole out on one side of the box, screwed the fan on and drilled a few small hole in the other side of the box and wired it in with the switch.

Job took 10 minutes.

The very best candle wax is the the wax from candles meant for under water use. Army surplus stores sell them.

So, flow controllers at about a tenth of the price.
Anyone want to invent/concoct/manufacture/cobble together an auto charger/split relay thing for charging the system battery from the alternator?
I paid £130 for my flow reg & auto charge. Flow-pukka. Auto-poop.

Would you mind saying what your mileage & water use is per week?
And do you have to auxiliary charge at all?
Title: Re: DIY Controller (for under £15) Instructions...
Post by: Don Kee on January 25, 2015, 07:36:00 pm
Around 60miles a week (tops)
(Mileage is sort of irrelevant mate, as its more about the time spent with the van on. Although i guess they are usually linked)

400litres a day (ish)


Had to bench charge my bat once in the last year, and that was more as a just in case rather than out of necessity

Sounds like a goer!
I use more water but I'm doing 60odd miles a day.
This'll be 3rd time lucky but I'll give it a go.

I've gotten around to installing the voltage meter and I tested it out on a battery:

(http://www.cleanitup.co.uk/smf/1423158838_Tosh1.jpg)

Seems to be working great.

I'll stick it in the van at the weekend.  I think the voltmeter is surplus to requirements; it's just a gimmick, but I do like the light-up led switch on the top.  With my current switches I find myself double checking them to make sure they're switched off, so a light on the switch will be helpful.

Not bad for under £20!  As someone who thought of himself as cack-handed when it comes to this stuff, I quite enjoyed doing it too.  I surprise myself sometimes.

Any suggestions or improvements would be welcomed.
Title: Re: DIY Controller (for under £15) Instructions...
Post by: Tom White on February 05, 2015, 06:04:19 pm
I just had another thought; if I installed a voltmeter on the output wires, would that reading vary as I increased or decreased the flow with the dial?
Title: Re: DIY Controller (for under £15) Instructions...
Post by: Don Kee on February 05, 2015, 06:15:01 pm
(I think) you'd get the same reading mate
The controller you've made controls the volts to adjust the flow so (again, i think) the draw from the battery would vary, and so the output would be the same as the input...

So that screen you have put in the controller should show the varying voltage differences without the need for another voltmetre...
(I'm assuming in the pic, your battery is on charge?)

(Spruce or ian sheppard may be able to tell you for definite!)


It looks good mate, you've done a good job
I was going to do one of these myself after your post, but i managed to get a varistream for £25, but definitley one for the future!

I reckon it'd be easy to flog these for £50 on ebay, and easy to 'mass produce' too.

But no.  However, they're dead easy to make; some poor Chinese child - hand-cuffed to a work bench - did the hard stuff when he/she made the voltage regulator circuit board.

I have a controller very similar to this (company who supplied it no longer trading). It is 9 years old and has not given me one day of trouble. I find it bemusing the amount of posts about the more common type of controller with calibration, dead end issues etc, plus they seem to pack up within a few years and need replacing. Over complicated IMO.

Used mine for the first time today, well impressed with it
didn't go for a volt meter as i wanted to keep it simple like me
Should save me alot of water as i used to control the flow from the tap but ever time i was moving the tap was dragging on the floor and increasing the flow.Just need to find an easier way to turn the water on and on instead of looking round for the tap.
might try cable tying the tap to the bottom of the pole.

Spot on, Rob, glad you like it.

As for a tap, I use my pole hose externally, and I use the kind of pole hose you can easily bend and it turns off the water straight away.

There's loads of advantages to using external pole hose:

1.  It's easier to extend or contract the pole (you can rest the butt on your foot too).
2.  You don't get dirt inside the pole.
3.  You can easily remove the brush head (I sometimes - if there's a lot of ground floor work - swap the brush head onto a short aluminium pole - it's just easier).
4.  And the BIGGIE - when you want to stop your flow, you just nip a handy piece of pole hose.

I've tried taps and aquadapters, but I find this the best method.

Job jobbed.

You will need to wire up your pump's pressure switch (if it's not already done); it's this that needs calibrating.

If you need more info, give me a shout.

You no what i've never try'd the hose on the outside and im always standing/tripping over the hose around my feet, i'll give it a whirl on monday.

I tried adjusting my pressure switch but it didn't seem to make much difference so just left if  ;D

Tosh, i'm just about to order a voltmeter for mine. Did you get a two wire one or a three wire one ? Either way could you say how you wired yours up ?

It was two wire, and it was dead easy to solder to the switch. 

1.  The negative to the negative post (which will be the same one the negative from the power supply goes to).

2.  The positive to the positive post; the one that takes the power to the circuit board - not the post that the positive power lead goes to.

If you wire the positive to the other post, the one from the battery, your voltage regulator will just stay on, all of the time, even when the controller is switched off.

It's simple; though you may have to just look at it for a while.

It's simple; though you may have to just look at it for a while.

Ok got that. There's some three wire ones advertised. I'll steer clear and get the two wire. Voltmeter essential for me as i'm lazy and hate charging them untill i have to. So that'll give me the heads up when it needs charging. I carry a spare battery too. Cheers.

(I think) you'd get the same reading mate
The controller you've made controls the volts to adjust the flow so (again, i think) the draw from the battery would vary, and so the output would be the same as the input...

So that screen you have put in the controller should show the varying voltage differences without the need for another voltmetre...
(I'm assuming in the pic, your battery is on charge?)

(Spruce or ian sheppard may be able to tell you for definite!)


It looks good mate, you've done a good job
I was going to do one of these myself after your post, but i managed to get a varistream for £25, but definitley one for the future!

Yes you will. You are exactly right Don.

The controller Tosh has put in is a PWM controller (Pulse Width Modulator.)

It will send pulses of your current battery voltage to the motor. (Pulses = on and then off.) The slower you run your motor the longer the off section of the pulse.

Flat out     = on -----------------------------------------------------

Not so fast = on --- off --- on --- off --- on.

Slow         = on -- off ------------ on -- off ------------ on.

(Hope that makes sense).   :D

The guage will be on if you 'splice' or join it between your switch and modulator. It will be off when you switch the pump off as Tosh says.

If you 'splice' it after your modulator the display will flicker when the pump is running, but I wouldn't know if your eye would see it or not as those pulses are very quick.

Here you go.  I think it looks a bit confusing, but it's pretty straightforward.  The meter wires are the thinner ones bottom right of the picture as you see it.  You see the black one goes to the post on the far right (with the other negatives) and the red one goes to the middle post. 

The red wire on the far left is power in post (from the battery) and if you attached it to this one, the meter would be on all the time, even when the pump was switched off.

Mine cost me £37 for two. The volt meters where almost £4 each. Whats that, £18.50 for each controller? I never fitted a split charger, although i did look at the ones someone linked to back in this thread, they look good.

Nice work

It's dead easy, Poleking; you just make sure you get circular switches and voltmeters; then it's just a case of drilling (not cutting) the holes where you want your items to go.

These - seriously - do not give the same problems that off the shelf flow controllers do.  There's no re-calibration needed, just because it's warmed up a bit (or gotten colder) and it's quite happy to run on a sub-standard battery without cutting out.

My original one must be about a year old now; not one single problem; it just does what I want it to do - control the flow.

Title: Re: DIY Controller (for under £15) Instructions...

Ive just got my flow controller back from my mate who's repaired it.
Gratis.

Its about 3 years old now and I've not a problem other than this.
I'll see how it goes and if it packs up, I'll do what you & CC have done.
Still unsure on the split charger.
I'd like to use the one I've bought. I'll try it at the weekend and see how we go.

I can think of a few improvements for my next one though.

I wired one up, and done same as your diagram. I found it a bit of a pain putting two then three wires together on the switch terminal. Then it dawned on me, after the event (normal for me !! :-) ), the voltmeter wires can just go to the terminals on the switchboard itself (the two right hand ones), it'll be much easier this way.

Also the controller in my van today was flashing up "batt", still working ok, but still flashing up. It also showed a voltage of 12.4v. I brought the battery in to test this new controller out and the voltmeter on the controller i just made showed 12.7v . I tested the accuracy of this with a multimeter, and the multimeter showed 12.7V. I realise my van controller may need rewiring with good contacts, so the point i'm making is just them small voltmeters are accurate.

 I'm very happy with the result, and just about to order a few more bits to make some more up , cheers Tosh !!   :-)

Post by: DeLuce on March 22, 2015, 12:57:22 pm
Looks good mate, good post


When you say only needs calibrating once, how do you calibrate it?
I'm assuming it runs off the pumps pressure switch, so wouldn't need 'calibrating', just a pressure change on the p/s itself?

Thanks; yes, you're right - thanks for clarifying my post.  Just the pump's pressure switch would need calibrating.

For those who don't know, just connect hose reel to pump, and pole to hose reel and turn it on.

At the bottom of your pump (on a Shurflo anyway) there's a hexagonal 'nut' where the arrow is pointing:

(http://www.cleanitup.co.uk/smf/1421952326_Tosh1.jpg)

Just adjust that so the water flows nicely - your normal working flow - yet when you 'dead end' the flow (whichever method you use to stop the flow), the pump shuts down pretty much straight away.

I've only ever had to do this once, unlike my old electronic flow controllers, which made me do it if the temperature changed.
I've got my box working OK, the only niggle being that I'm having a job calibrating shut off. I've tried adjusting the allen key at the base but can't get it to shut off any quicker than 14secs, with screw fully in to fully out! What do you think I'm doing wrong? I have the wires attached to the pressure switch connections. Any thing I've missed do you think? ???

Have you tried winding the hexy screw all the way in and work outwards from there?  Yes, you have.  I think mine is about halfway.

Are you sure your pressure switch is okay?  They cost about £2.50 to replace and they're very easy to do.

Title: Re: DIY Controller (for under £15) Instructions...
Post by: Tom White on March 22, 2015, 01:16:45 pm
Another tip would be to take the pressure switch apart, the plastic housing.  Do it carefully over something so if any bits fall out, like a spring, you don't lose them.

Then you can see what effect the turning of the hexy screw has on the switch.

I don't think it matters what wire you use to run to your pressure switch; it just breaks the connection when the pressure builds up.

Sorry, I never saw this; no I don't but I just bought a little connector from Wilkinson's that unplugs from the wire that comes from the battery, so I can just unplug it, disconnect the hoses and take the pumps and controllers into the house.

Buy two of everything, to use as a spare, however my first controller is still going strong and it's about 18 months old now. 

I NEVER have a problem - not one - with my flow controllers; no messing about, no recalibrating them because it's gotten colder  or warmer; no problems at at.  My pumps are about four or five years old too; no problems with them either.

A simple tweak to this design,.. when you're choosing your speed controller off ebay - find one with 5 wires going to the dial instead of the standard 3 wires - - that means it has the on/off switch built in & you don't need to bother wiring in a separate one. 

Something like this: http://www.ebay.ie/itm/MAX-10-50V-2000W-40A-12V-24V-48V-DC-Motor-Speed-Control-PWM-HHO-RC-Controller-/201399689235?hash=item2ee45b6013

I put a voltmeter on mine for the specific reason i did not want to run the battery on less than 11 volts. If you run less, or run until the battery is dead you'll kill your battery pretty quick. If you're breaking the numpty off, make a protective cover to go round it so you don't break it off.

Not particularly knocking it off Clear, They just don't last keep altering flow as it is  very flimsy. You just need to be heavier handed the odd time and it snaps off

Tosh I have found the nob/ dial call it what you will..tends to break off very easily.
Had a similar set up in my van but just used normal togle switch

Ok mate, i've never had a prob with mine. I fitted two on my mates van, and he's a yardstick for being thick, and his co worker is off the scale of thickness. I.e you can't even let him connect a battery up he'll get it wrong, anyway all ours are still intact with no issues.   ;D

Which reminds me, i'm not suggesting anyone goes and does it but we've found if you do connect the battery the wrong way round it just doesn't work. But also, does not blow a fuse nor scupper your controller. All is fine. Well after you discover you've got it wrong and connect correctly !!  ;D

No problems with the nobs on mine!  Must be about two years old, or older now; still going strong.

I've just made another DIY controller - a spare - for under £15.  These are class, they only require calibration once (the air temperature doesn't affect them), and they don't require a battery in good nick to work either; they'll run on any old 12v battery. 

I've included an on/off LED switch - though I think that's superfluous to requirments; it would work without it and be even simpler to produce.  An LED on/off switch lets me know if it's on at a glance, and it also means I don't have to turn the dial to turn it on (I'm very lazy).

(http://www.cleanitup.co.uk/smf/1421950765_Tosh4.jpg)

Anyway, these are the parts I purchased:

12v LED rocker switch £2.00
http://www.ebay.co.uk/itm/261513977084?_trksid=p2060778.m2749.l2649&var=560391577650&ssPageName=STRK%3AMEBIDX%3AIT

Waterproof Project Box 115*90*55mm £4.52
http://www.ebay.co.uk/itm/201212241692?_trksid=p2060778.m2749.l2649&var=500405437151&ssPageName=STRK%3AMEBIDX%3AIT

10A 12V~40V PWM DC Motor Speed Control Switch Controller Volt Regulator £7.00
http://www.ebay.co.uk/itm/10A-12V-40V-PWM-DC-Motor-Speed-Control-Switch-Controller-Volt-Regulator-Dimmer-/121250426718?pt=UK_BOI_Industrial_Automation_Control_ET&hash=item1c3b16af5e

I drilled the holes for the voltage regulator and the switch and a hole at the rear for the wires that go to the pump and the battery:

Then I wired it up; soldering the wires on the switch (first time soldering; which why it looks rough):

(http://www.cleanitup.co.uk/smf/1421951024_Tosh3.jpg)

I was unsure how to solder or wire a rocker switch, but it's all on youtube:

How to wire a rocker switch:

How to solder:
https://www.youtube.com/watch?v=BLfXXRfRIzY

The wiring on the voltage regulator is easy; on the rear it tells you what's what, with regards motor +- and battery +-.

I quite enjoyed doing it too.

If anyone fancies a bash, don't be shy to ask questions, though it's pretty straightforward.

And if anyone can suggest any improvements, I'm all ears.

Oh, Ionics sell a similar, with VAT and delivery, it's £210.00

(http://www.cleanitup.co.uk/smf/1421951528_Tosh1.jpg)

And it doesn't even have an LED switch on it!  :'( :'(
  can you do a D I Y footage of how to do it because I'm very interested sick of paying a lot of money for these controllers thanks

LOL that's one of the reasons why I work by myself as I only have to worry about my own stupidity.

ive been making these and knocking them out for £25 plus £5 postage, they dont have a voltage display but they have a flow display, i stopped making the controllers with voltage display as they took me longer to wire up!!
yes we know you can make them yourself slightly cheaper but i've put a little bit on for my labour etc and they're still cheap, i have one of these fitted in my van now and they look and work a treat!!

quick question guys
these 10A 12V~40V PWM DC Motor Speed Control Switch Controller Volt Regulator
you have have two wires on the pump one red one black and a wire from the pressure switch in to the pump on a shurflo
so i have connected the red black to the speed controller board wer it states motor and the battery ones to the battery all good switches on pump runs 
but the controller wont slow the pump down
should i hear a drop in the pump as it is turned down and once its fully turned down should the pump stop?
Thanks

Yes you should be able to hear it going faster or slower. And i think you can slow it down so much that it stops. If yours is wired correctly, and from what you say it sounds like it is i would suspect a faulty motor controller.

My flow controller went pear-shaped on Friday morning, so I fitted a small switch to it (I had got this from Wilkos a long time ago, just for this kind of problem), so I could turn it off and on; using the pump's pressure switch for the rest of the day.  It meant working at 'full blast', but that's fine by me.

And I've just fitted a spare controller that I had ready made; it took about ten minutes to connect it up.

No downtime.

I'll order another two volt regulator and another two switches and re-make the one I've just taken out of the van.

It's very simple because the boxes already have the correct holes cut in them and I just re-use the wires; they're already cut to the right length.
