Foam cutter - variable voltage power supply

[Tsunami33]

Can't seem to find an inexpensive, fit for purpose AC to DC variable voltage power supply. Wanted to start experimenting with foam cutting.

I've tried Sim Lim Tower and some other places along Jalan Besar.

Does anyone know where I can get one? Can be 2nd-hand / used too.

Else, I have a DC 12V regulator for my Triton, was going to vary the distance of contacts.

Hello Dave;

Link a servo driver to a 3 cell brushed ESC. 3 cell brushed ESC has 2 leads, one positive and one neg. These go to your croc clips.

Check out this article here.

Anyway how this works is that the brushed ESC output varies according to the throttle, and the throttle varies according to the inputs by your receiver..... anyway read the article, it should give you more insight.
