Hi all
I'm about to have to quarantine in the UK for 14 days. So I thought that was a good opportunity to advance a project I've had in mind for a while. I'm calling for collaborators if anyone is interested.
The project is a hobby level pool management system. The features would be
pH measurement
pH dosing
ORP measurement
Liquid chlorine dosing and
SWCG control
SWCG (the whole thing other than the cell).
Outside of the cell I'm targeting a price point roughly as follows
Peristaltic pumps *3: £15ea
ORP sensor: £25
pH sensor: £15
Depth sensors for the acid/base/chlorine tanks: £5ea
Components and board fab: £25
Toroidal transformer 230vA. No idea of price.
Probably also need a flow switch and maybe an optional pressure transducer. Because why not.
So roughly £120 + transformer + cell
These are one-off prices. I'm quite sure the price point could be pushed way down in some quantity.
I've got replacement plates for my 1440cm2 cell which are costing £175 delivered incl tax. Against the manufacturer replacement cost of £1100
Additionally there would be
* Design files for housing
* Web/mobile interface design and coding
* Firmware coding
* Sample Alexa skill to query and control the interface vocally.
My intent is to make this entirely open source. So providing all files in usable and modifiable formats.
I've got the time available to get a long way into the design of all this in early September, if not finish it. but I'd love collaborators and people to help answer questions about the electrolysis chemistry, UX and UI design etc. And if anyone has microelectronics expertise, to collaborate on the design of the circuitry.
I can also add control of standard vfd devices too (either by modbus or the usual four switch method), if that's thought useful.
I'm not trying to disrupt the market at all. But this might be something that the tinkerers amongst us might enjoy building. And that way you could make it yours.
When I say hobby grade, I suspect that it will function and be as safe as the stuff I've currently got. I've taken that to bits and it's a very basic design. The fundamentals are all ok but these days we can be much more efficient at.much lower energy costs.
Any interest let me know. Looking forward to chatting.
