Pump power

[mhewitson]

Hi... I did search...but struggled to come up with anything.

Any suggestions on what to use to power a 12V DC solar pump. Ideally I'd live variable control, at a small size and cheap cost.
If possible something that can be built into a project box at some point.

Many thanks,

fwiw i use an off the shelf tattoo gun psu with my lil brown solar pump, circa £10 from ebay some time ago, it also doubles up as the psu for my pcfan magnet stirbar solution

be mindful that they can deliver upto 18v at full power iirc but mine has a nice easy dial and led display to control and indicate output voltage, and i find i generally run it between 8-10v

wow they have gone up in price.. https://www.ebay.co.uk/itm/Tattoo-P...11:m:mWzNYkuq0cOORBb_rCKScbg&var=620665665295

Homebrew builder has a 12v supply for small pumps.
For flow control just add a tap on the outlet of the pump. This will control the flow rate.
