So that previous coil was about 4 layers, unknown number of turns.
Using the Microwinder I was able to get 6 layers, very neatly wound, not perfect, just neat, on a 2mm core with 791 turns. Inductance was 5.95mH. Outside Diameter was 3.13mm.
For reference, I’m trying to fit into these glass tube specs.
Need more turns. But no room for it. Gonna try smaller cores, but having difficulties holding on to them. I have ideas, need to explore some more.
