Subscription needed????

Not for the build lol

OK I get it the connector on the led dimmer is a bit flakey, but putting it in a 1000% bigger box???
Why not just hot glue the connector to the unit.

I added an inline female socket to the input line, so I could just plug in a wall wort with a 5.2mm plug on it. You could do the same on the other side but reverse the plug/socket so if needed you could bypass the dimmer.

I no longer have the unit so can't post pics though.

The dimmer works a speed controler for the pump its done that way so all in one unit !!!!

I just hard-wired mine to a 12v DC supply and control the flow via the ball valve.

The idea of the post was to show people wot you can do with a sky router !!!! As it just looks neat and tidy plus no wires on open like on speed controler

Yeah but you didn't use a sky router, just the box Could have been any box.

Fffs talk about picking faults nowt else better to do

If you wanted to build it cheaper, you could just buy the pot - they're about 50p. The other bits on the dimmer are superfluous.

No it is a pwm controller not just a pot for fan speed control.
If you put a pot in series it would just burn out after the first second or so.

@tazuk if I put up a howto using a SPECIFIC item then I expect to use the item not just the shell of it. You say sky ROUTER, not sky router box.
I thought you had somehow reprogrammed the router to do speed control, that would have been interesting this is just a box.

These solar pumps run on a 12v dc supply - you're not gonna burn up a pot like this by putting it in series with the supply voltage - I've done it countless times with guitar pedals.

I'm not seeing anything except a pot attached to a PCB through to a wiring terminal - are there any components on the PCB?

Underneath is an NE555 (timer chip) and assorted bits to do the pwm. I DID check mine out when it first came, wondering how they could supply it so cheaply. I couldn't even buy the bits for the cost of it.

Yeah that is the purpose of a pot, the purpose of the led dimmer was just that dimming leds. That you can't do by just lowering the voltage. Using pwm they supply the full 12V at all times, just sometimes not very often (Mark to space ratio of the 12V line if you are interested in electronics)
