Dami":1i0pxa1m said:Didn’t want to go for some expensive power unit so got six 9V batteries and a cheap voltage/current modulator that allowed me to adjust the voltage between 0-50V. There’s a lot of good advices on this on the web but all of them were with only batteries (hard to adjust voltage) or with those expensive dc power units. So just tried to find a good combination of both.
