From 3D model to actual prototype, here’s the Infinity Driver v0.93, front and back views. The coils are 16Ω gauge 35 magnet wire, with Neodymium N42 core. The 5mm high coils are shielded by 2.5mm thick permalloy rings. The rings focus the magnetic field and minimise electro-magnetic fields leaking out from the coil. The amplifiers are 3 pairs of high-efficiency 2.4W Class D amplifiers: MAX98302. The entire assembly fits inside a standard humbucker.
