Post memes here.
A meme is an idea, behavior, or style that spreads by means of imitation from person to person within a culture and often carries symbolic meaning representing a particular phenomenon or theme.
An Internet meme or meme, is a cultural item that is spread via the Internet, often through social media platforms. The name is by the concept of memes proposed by Richard Dawkins in 1972. Internet memes can take various forms, such as images, videos, GIFs, and various other viral sensations.

I always thought these things were brilliant but was never sure how they worked. They basically had a recording head that sat against the playback head of the tape player and sent a signal into it, right? I was never even sure of that.
So normally the magnetic tape would spin by the reader in the player. However instead of a tape they put an electro magnet there. Then they use the same technique to simulate a magnetic tape. Tadaa you made digital audio into electromagnetic audio
There's actually no digital audio involved anywhere in this process. It's all analog.
A magnetic tape cassette holds raw wave data of the sounds it records. Just like a vinyl record, except the groove is in the magnetic field instead of physically etched into the surface of the tape, and the needle is an electromagnet instead of, well, a needle.
An audio cable using a standard 3.5mm jack also transmits raw wave data. It has to, because the electromagnetic pulses in the cable are what directly drive the electromagnets in whatever speakers they're hooked up to. If it's coming out of a digital player, the player has to convert the signal on its own using an onboard digital-to-analog converter (a DAC).
The neat part is that since a tape deck read head is looking for an analog wave signal, and an analog wave signal is what an aux cable carries, the two are directly compatible with one another. If you actually crack one of these tape deck hacks open, you'll find the whole thing is completely empty, save for the audio cable wires going directly to the write head that mimics the tape. Beyond that, there's no conversion equipment, no circuit board, nothing. It's a direct pass-through.
The body of the thing is nothing more than an elaborate way to trip all the mechanisms in the tape deck to trick it into thinking it's holding a valid cassette, while simply holding the write head fixed in the proper spot.
I'm sure you already know all of this. I just think it's really cool and I enjoy talking about it. Analog tech is amazing.
And the best part is, because the signal is so clean, and there’s no crappy tape grinding across the head adding noise, the audio quality is damn near on par with just connecting the aux directly to the amplifier.
This is my favorite thread of the day. I learned something, and it brought back memories of plugging one of these into my parents '87 Buick LeSabre wagon. Complete with wood grain panels. Yeah, I didn't date much back then.
That's what I always thought - I think it would work to use a recording head as the electromagnet, treating the player's playback head like tape.
Gonna drop this here for those interested.

Holy Crap at first I thought that was Chandler. Great video tho, and I'll be damned, those things work exactly like I always assumed. I really thought that explanation would turn out to be too simple. Never thought about also having to make both spools turn so the player won't think the tape has run out.
I saw that thumbnail of the table and immediately knew what channel it was.
