[QUOTE="steelPHASE, post: 469700, member: 13488"] Easiest way (and cheap) is just to buy a dc - dc converter module, remove the pot on the board and replace it with an external one. Using a meter add resistors to the pot so that the range of the pot corresponds to the voltage range required. I would probably also add a decent electro cap on the output of the module. something like this : [url]https://www.ebay.com.au/itm/3x-DC-DC-Adjustable-Step-up-Power-Supply-Voltage-Converter-Module-35V-Heatsink/281281361505?epid=15023470767&hash=item417dacf661:g:yqIAAOxy3HJTGu20:rk:27:pf:0[/url] [img]https://www.prospectingaustralia.com/forum/img/member-images/13488/1549489651_s-l1600.jpg[/img] [/QUOTE]
