5uH Short Wave Coil

thingiverse

The input coil for the short wave tube receiver. Inductance is roughly five microHenry and can be altered by adjusting the number of windings on it. If needed, I will make available a detailed design plan for the receiver, including an example setup such as a simple regenerative Audion amplifier circuit. Additionally, I have installed a unique, aesthetically pleasing (spider) coil, which serves as an upgrade to this basic setup. Later on, more elaborate designs and models will be showcased here once they are complete. Currently in progress is the machine for manufacturing cross-coils, including the device needed to accurately wind them into their precise forms. Here is a video demonstrating its operation during still preliminary stages: https://youtu.be/e3_o3FKZH5o https://www.youtube.com/watch?v=fZ88H5ARjQY&feature=youtu.be
