Is it possible to modify this watt dial to work with less current? Answered
I've got a few of these watt dials that I would love to use in a project, however, they will not be reading wattages and will rather be controlled with Arduino. Right now they are set up to read up to 3750 w at 125v, which is much more power than I can source with an Arduino or would be achievable with this project.
The way it is set up is that current goes through the magnetic coil and creates a magnetic field perpendicular, attracting a small magnetic block (slightly visible in the photo). Would simply rewrapping the coil with thinner magnet wire in more coils work?
