I'm moved by all the supportive emails, donations and pledges that have come in since I published the last video. You guys have basically changed the entire equation over night and have given me a lot more hope for the near future! Thank you all so so much!

Very good! I want to do this to my old stereo which also has 2 RCA line in connectors

[dozerjohn]

You sound much, much more cheerful and energetic in this video, good stuff man, good stuff.

well done! I had never seen a Nokia cassette player in my life!

"the 2 open 2 close" switch configuration is called "double pole double throw" or simply "DPDT" here in the USA but I just watched all three of those videos and can't remember from which one the switch was incorporated... ahaha anyways, great videos, the intro to them are awesome as well! peace.

Thanks for sharing this. I just finished adding bluetooth to a Sony CFS-930 as a birthday present for my sister. I used (I think) the same bluetooth module, with an LM317-based regulator to drop the internal 9-10V down to 3.7V, and 4-pole dual-throw (4P2T or 4PDT) switch to handle the connections. The tape deck still works, the radio still works and, with a flick of the new switch on the back, the bluetooth works! (with some noise from a ground loop somewhere). Your videos were a great guide and I found them very helpful. Thanks again!

i found this video and im fucking glad, this is exactly what i need cos earlier today my neighbour just asked if i could help figure a bluetooth option for his old Sony mp3/tape player he loves dearly.
as a sort of Yes guy i did but i knew i was in trouble as soon as i realised the line-in/Aux missing, not even an RCA connectors at the back🤣.my hope was to simply get him a 5.0 bluetooth module from Amazon to serve as the middle man between SONY and his SAMSUNG smartphone .
well anyway its a blessing to find GEMS on YT from time to time like some brilliant, overly generous person sharing a library of wealth of knowledge..just priceless and inspiring!!

The name "RCA" connectors comes from the name Radio Corporation of America, which was the company that basically began the age of radio and then television, and then color tv, in the United States. They were located in New York City, and literally created the radio and television broadcast industry, by either buying up every electronics-related patents and inventions, or inventing them (as in the case of NTSC color tv) in their own laboratories. They also invented the 45-rpm vinyl record format, in 1949.
They invented the connector as a simple method of making internal connections in their radio and phonograph consoles. The connector became very popular, and has been called the "RCA" (or "phono") connector ever since. There is a wikipedia entry called 'RCA connector' where you can find its entire history.

I loved this project - there is far too much useful stuff that gets discarded even though it could be upgraded like this. Just set up my Patreon account so I can help support your videos - keep them coming!

In Belgium we use the name Cynch too. and the certain microphones you talk about that need to be pre amped are only condenser microphones.

Another great video. Glad things are looking up for you.
Maybe on day, you can buy you're own home( a fixer upper) and have a lot more projects to share w/ you're subscribers.

Its not too often I hear RCA these days with the move towards HDMI and Digital Audio, but the term still gets used (though sometimes people drop the name in favor of what the function of the RCA jacks do, like AUX for AUxilery inputs or Phono for Record Player inputs on stereos/amps)

Dude, those soundtracks are something else!:)

I've learned some new things! I've done a few of these hacks before. All with the TDA7492P 50W+50W Wireless Bluetooth 4.0 Audio Receiver Digital Amplifier Board.

I have been experiencing some wierd noise (tied to the rpm of the engine) when I use that card in my car stereo. Maybe it's because I'm using a shitty 12v cigarette plug? Are those plugs giving bad dc?

I would like to add Bluetooth in Panasonic RX-DT690. There is no in-line/Aux port. What should I do?

[TheloniousBosch]

In my part of the US they are either "RCA" connectors, or some older guys call them "phono plugs", as they old connections from phonographs often used the same type of plug, although they were usually black and mono, so only one cable carrying a single channel of audio. Some older systems used the same connector style as RCA for things like the antenna, loudspeakers, etc.

very nice audio inputs hacks - I really like how you explain and do the hacks. 10+

[davidjenkins]

RCA in the UK. Cinch are a connector manufacturer...

[Resqueda]

Hoping you can help. I have a security camera that has a weak speaker. I only have access to the black and red speaker wires. The camera is not able to be opened. Is there anyway to connect these two wires to a Bluetooth transmitter as an audio output?

I love this! Gonna try it on my old hifi speaker, thank you!
