Tbh this was somewhat underwhelming… I expected using a microcontroller+motor to replace the mechanisms of a regular cassette mechanism, or some other uses of modern tech for the cassette.
Instead, it’s just… a tape recorder connected, in a somewhat convoluted way, to spotify.
Installing a Linux distro on a laptop is frontpage material so this sounds about right.
Flagging seems extreme, but this is a very low information post about audio adapters, with a smidge about amplification. I went in expecting some kind of arduino-to-electromagnet jiggery-pokery, but I suppose that just means set myself up for disappointment.
