How to Add a Line-In and Bluetooth to Old Stereo Systems (3)

[@ThePostApocalypticInventor]

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!

[@OzmoMac]

your welcome

[@sheep1ewe]

I hawe not yet found a single one of Your videos that i not love. (and i hawe watched hem all since the beginning, most of them several times)

[@Skyefuego]

The Post Apocalyptic Inventor hey I'm trying this hack with my 2004 dodge neon stock radio how do I find the diagram?

[@sonnybrecken3818]

I guess it is kinda randomly asking but does anyone know of a good site to stream new movies online ?

[@connorjameson3152]

@Sonny Brecken lately I have been using Flixzone. You can find it on google :)

[@dozerjohn]

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

[@seyyedsabet4547]

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

[@fredtumusiime3852]

hahahaha

[@differentlyhairy]

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!

[@joeeastman]

"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.

[@johnrenwick5464]

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

[@cjay2]

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.

[@deadheadliving]

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!!

[@Dylan_Lanckman]

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.

[@voneschenbachmusic]

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!

[@nekomasteryoutube3232]

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)

[@modmen.]

The name "Cinch" is also used in Poland. Cinch is also used to name a peace of a horse saddle (the strap you put around the horses belly). No idea how those are similar.

in Slovenia is also called činč

[@ThelBosch]

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.

[@Torsan1977]

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?

[@Torsan1977]

+simontay1984 Thank you my friend! I will look into this and try to make a fix!

[@Torsan1977]

Yeah! I'll see what I can find! Thank you!

[@notionSunday]

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.

[@tilleytristan]

Your videos are amazing! I was wondering if I could bypass the AM radio, since no one really ever listens to that anyhow, and place a line in AUX there? I don't like adding switches to my faceplate, so using the AM radio setting switch is what I'm trying to accomplish. Are there any issues with AM being amplified strangely or something? I would be fine with pulling the AM guts.

[@davidjenkins7611]

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

[@ManosHalikis]

Dude, those soundtracks are something else!:)

[@cherryturbojames]

just wanted to say a massive thanks I've managed to do this on an 80s boom box and it worked perfectly even without implenting switches and you don't need to press play . thanks again

[@19BuffaloStreet]

Some models of cassette players require the play button to be pressed before allowing any audio to pass from the heads. And then, some don't.

[@vincentleeadams]

And I also love American and Japanese engineering to, and this channel is excellent!

[@coki1389]

Činč name for RCA is used on Balkan also

[@willcampion4057]

Thanks for the inspiration, AUX line-in and usb power added to an old Sony hi-fi. It is now the speakers for my PC!

[@MJ12475]

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

[@Resqueda01]

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?

[@atzkey]

I tend to believe, that "cinch" has Spanish origins, and denotes a strap that encircles the horse barrel in order to hold the saddle. And after this word has been adopted in English and some other languages, it obtained a more generic meaning "to tightly encircle something". Like, for example, a type of corset - "waist cincher".

[@211teitake]

Is it possible to show us how to modify an existing line-in RCA which is only for tape recording so that external audio sources can be played on such boombox? Thank you.

[@ilank43]

Where is the link to the Bluethooth device you bought in Ebay?

[@krakonoszkrusnychhor400]

Cinch is actually used in Czech Republic as well (or at least was when people still used it, ...).

[@JA-qi1fb]

And now I see you have already retro-fitted Bluetooth to an old boom box!

[@bestofbritish4998]

?would it be diffrant thing to highoutput and low out put speakers ect do you think ?

[@Seegalgalguntijak]

What is the music from your phone that you tested the line-in and bluetooth with?

[@jethrowomber]

I'm in the process of doing this to my 20yrold aiwa boom box...I just discovered I can use the mic input as aux (yes 20yrs ago Aux input was not a thing on all radios ) if I push play on the tape deck...yeah no more radio..I even took swapped out the speakers for some Kenwood's and now I gotta get inside to bypass no RCA so I can add an eq a amp and some boom.

[@q12x]

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

[@rhoodj]

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

[@PunjabiMK]

Hallo sir ham Bluetooth ki jo internal sound hote ha who hm change kr sakte ha example = Bluetooth smooth, jb on hota ha

[@dodgeman777]

I have a very similar Stereo (Hitachi TRK-W530E) which I have been meaning to modify with an internal bluetooth module such as this, but it runs from 8 D-cell/IEC R20 batteries which is inconvenient and expensive. I'm planning on replacing them with a single 12v rechargeable power pack but I'm confused as to which variety of battery would be appropriate for this application considering the runtime needed as well as the available space inside the compartment. May I ask what you would recommend?

[@jarispe32]

Where can I purchase the bluetooth receiver used in this awesome video? Can you share a link or give model name

[@joseyneighbors5230]

Nice job and I love your accent

[@abeleballestri612]

I enjoyed this video very much indeed. I have a question for you. I have heard that in Norway the FM transmission have ended and have taken its place the DAB system instead and all the receiver with FM are now practically dead. Do you know if it will be possible for us still eny

[@abeleballestri612]

Still enjoying fm if we can in some way create a device likeyou have done with the I phone, to be able to convert and make the dab possible to receive in Analogie system for all our nice old fm receivers ? I am curious to know your opinion about it. Thanks very much for your advice.

[@kimschan2642]

abele ballestri

[@robgrune3284]

good vids. how would you add an isolated female mini audio trrs socket to a boom box?

[@byzhrad]

"cinch" (for rca conecotrors) is also used in other post-comunistic countries like Czech republic or Slovakia

[@dizzolve]

I Love your videos. I have purchased one of these exact receivers. Is there a way to hack the range of the device? it's range is 10m. Can it be improved to say -... 20m?

[@qasimshabir4236]

Sir where did you conection wires of Bluetooth audio in old tape area?? Please reply must

[@dharmang]

i have a tape like that of Sony and i cant separate two speakers from both sides, it has two wires out from one speaker and its detachable. Is there any way i can use those speakers?

[@frankrumble6754]

PLEASE TELL ME; how can I hook up my MP3 player to my boombox speakers without soldering anything around inside.. I don't need Bluetooth device just a simple MP3 player to Boombox wiring connection.

[@lostgroovemusic8494]

Great information here loved the video just one thing with a hi fi cd system where it has a line in RCA red and white and you have a separate cassette deck can you record CDs on to a blank cassette

[@backgambit3475]

How would you Install a Bluetooth into a radio from the 1920s with tubes in them

[@Rainbow__cookie]

Lol

[@HelloKittyFanMan]

Not only do you not want to have to worry about the internal battery of the BT receiver being unchargeable after so many years, but even having to charge it separately would be a pain in the butt; it ought to act like it was part of the boombox all along. But then you could use the boombox's power supply to recharge it either from mains or from the boombox's batteries, but even that can present at least one overcomplexity problem: that the eventual nonrechargeability of that battery will come back to bite you. So yeah, I agree, ideally this would be best... but then of course there's that problem of audio noise that can come back to bite you as well. So hmm... "6 vs. half a dozen," eh? I like that you used the USB charger to keep charging receiver's battery while the boombox is powered by mains, but that doesn't address trying to get it done with the D cells, nor does it fix the eventual nonrechargeability, so it would be good to still find a more elegant/permanent solution. I guess there's still the buying of a modern combo boombox that already has these features, but there are only like maybe 2 models like this, if I remember right, so our choices are pretty limited. Although... maybe only 2 choices are all we need if they're good machines.

[@IntoTheDirtshop]

whats the range of the bluetooth for that unit?

[@hanvroman]

In holland it's mostly called tulips connectors or interlink cables..

[@shurdi3]

Here in Bulgaria, we call them чинч, which is pronounced the same way. When I was working as an IT in Croatia, they also called them chinch

[@Piotr94L]

+The Post Apocalyptic Inventor In Poland RCA connectors are also called "czincz" probably from German.

[@KnaufL]

We also use the same term for RCA here in Croatia.

[@rn2489]

my home DVD player has VCD,DVD AND USB options but I want an AUX connection how to modify it

[@mihkus]

Guys guys... Those 2 dollar bluetooth receivers are total crap in my point of view. Am I the only one finding them to have very poor highs and no low end? Werent those meant for old bt headsets or handsfree devices? Better get the 4$ CSR8635 module. You will be impressed by the quality of the sound. I promise.

[@shana_dmr]

These cheap 90s boomboxes are crap enough that it won't make big difference;)

[@mihkus]

Maybe..

[@aml_dv]

how can i unplug one speaker from a radio like this and convert to to 3.5mm?? is it possible..?? please help

[@powerzx]

In Poland it is also Chinch, and nobody would call it RCA :)

[@M0ntaroo]

that last song/music sounded like what Cyriak would use in his videos lol - freaky

[@poptartmcjelly7054]

In Lithuania we call RCA connectors "tulips" because the RCA plug looks like a tulip.

[@mrbigtbonevissoc]

Perfect!

[@donnaforsyth6818]

Will this work to connect Bluetooth headphones

[@H4mst3r.]

in Slovakia we call it "cinch" as well :)

[@robgrune3284]

Great ! Could you think of a way to hack my car stereo, so I can play music and video from a usb stick? My car has a DVD player. thanks!

[@yorudzhov]

Hey, guys. Using this tutorials, I was able to let the line-in work in my old Panasonic RX-DT37. (However, I just replaced the radio with line-in there) But now I am digging into a Sharp WQ-750HT(BQ) , couldn't find manual online, but it's OK. So I was able to understand, what's going where (thanks to this tutorial and 2 previous parts) but when I connect the line-in, instead of a tape this time, the sound is so distorted. Tried with radio as well - the result is the same. May it be, that I miss something? Like, mb, some resistors must be included for some models?

[@yorudzhov]

So actually, I found the reason soon after that comment. In Panasonic pre-amps are located on Tuner/Tape boards. And i easily modified several Panasonics, just connecting the line-in into the main board instead of the Turner/Tape boards. In 198X Sharp basically pre-amps are located on the main board. So it was also easy. I've connected the line-in into the "input" of Equalizer board. That's all.

[@sgtcrabfat]

I will give this a try, I have decent stereo system which maybe will soon get used again, Thank You.

[@avrahambrea1919]

I'm using only the speakers when I wired an auxiliary cord straight to my phone it's very quiet the phone clearly doesn't make enough power how can I add a plug-in power supply

[@ThePesmat]

they sell headphone amplifiers fairly cheap on amazon or theres schematics to make them all over the internet

[@catweazle62H]

Great video, thanks a bunch! I will try the same on a Panasonic RX E300 soon....

[@Letsexploreentomology]

what is the use of adding an mobile charger in the system 🤔🤔🤔

[@VictorAlexandrov]

We call them exactly the same in Bulgaria - chinch ;)

[@Zorz-PapaDubi1290]

In Serbia too :D

[@poorchava]

same in Poland :)

[@DreStyle]

dunno.. In Germany I just say RCA in.. cinch is also used in Netherlands.. it's just an abbreviation for RCA or tulip plug

[@adamj91]

Also in Poland. Actually I doubt than many people heard RCA name here.

[@DreStyle]

+Adam Jurzyk well RCA is global.. What I know.. Cinch is more European... That's what I understand

[@slugaool]

I also know them as tulp connector, (tulip)

[@canadapainter658]

will I able to use MP3 player to connect with Bluetooth receiver? or only Ipone or notebook.

[@cookieblunt6428]

Nobody asked

[@biff1tannen]

Nice video. Is it possible to add a dab radio into a old stereo like this?

[@vincentleeadams]

Damn! I love German engineering! Subscribed!

[@kindarhaz8429]

In Czech we are using "cinch" too.

[@welcometomychannelswelcome7261]

Great explanation.

[@funwithry1320]

Dood you are pro! Just subbed 💯

[@pajcov]

Sorry to be a pedant but thought you might like to know that "backside" in common English (UK) usage means bottom, butt, arse , buttocks etc. Commonly, the expression you need is "rear", "rear side", "reverse", "reverse side" or just "back" (without the side!). Not that I'd want to really change your charming and idiosyncratic way of speaking.

[@gaberrs2331]

It's different in English (America) where rear also means butt

[@ThelBosch]

Thank you for doing this!

[@jameslucas6589]

Makes sense to me; now can you tell me how to hack my Bluetooth so I can put a boom box in it? Is that a McIntosh boom box? Sounds soooo cool.

[@sowndefex]

Love this channel. I will for sure donate at the end of the month when I get paid. PLEASE TELL ME THE SYNTH MUSIC. Is it kraftwerk? please tell me!

[@jusb1066]

likely his own music, so as not to have copyright issues

[@John_Ridley]

I understand it's a more accessible project when you use a simple USB charger on AC to power things, but I think I would have preferred using a DC-DC buck converter to go from the unit's internal power, then it could have run the bluetooth from either AC or battery. Then again, the unit will probably never actually be used on battery. I think if I were using a unit like that much, I would put some 18650 lithium cells in along with charging circuitry - rather than buy C or D cells or whatever it is using.

[@jonnoMoto]

I guess that could be another project, 18650 conversion.

[@Seegalgalguntijak]

Quite the project. If you want to put 18650s in series, you'll have to balance their charge and so on.

[@John_Ridley]

Seegal Galguntijak Heck, charging multiple Liion cells is an off-the shelf, super cheap module. No design work necessary.

[@Seegalgalguntijak]

John Ridley You'd still have to get the right voltage and stuff. But yeah, I guess it's doable, and 18650s are commonly available (if you don't want to buy them, just harvest them out of some old laptop batteries).

[@John_Ridley]

Seegal Galguntijak You don't have to do anything. You can buy the module to handle the entire thing for dirt cheap. I have 18650s lying around, I use them in projects all the time, they're the easiest to deal with given the chargers and boost converters you can buy for about a buck on eBay these days.

[@amdhd6990]

we use "cinch" in slovakia too.

[@cookieblunt6428]

Nobody asked

[@zx8401ztv]

The Rca jacks are nicer to use than some connectors, a 5 pin Din was typical on older systems, not used so often now.

[@jusb1066]

i think German.French equipment used the 5 pin din a lot later than we did, in the UK it seemed to die out on the 70's systems.

[@zx8401ztv]

Your right, i just got used to the standard. Perhaps if i had been born in the 80's then the rca would be all i knew. The 5 pin din had a habit of not being a standard pinout, the earth was allways the middle pin, but the inputs and outputs could be at eather end, if you didnt have the correct cable you didnt get anywhere, a 1-1 cable or 1-5 cable, annoying at times lol :-D

[@jusb1066]

zx8401ztv ahh the days of having to solder your own wires and connectors! that continued well into the 80;s when it was cheaper to solder my own spectrum tape cables than to buy! yeah the din pinouts were trial and error, then they go and use it for midi as well!

[@zx8401ztv]

Yes i bought connectors from maplin, then tandy, i did much the same. Long live the speccy :-D, i still have a few on a shelf, wont get rid of. Also the 5 pin din was used on the back of ye-olde vcrs, i made the cables to rip off.... err make personal copys of videos lol :-D.

[@jusb1066]

zx8401ztv grumble,,,there was no tandy, and no maplin in my day! it was a matter of finding an electrical supplier, and back then it was trade accounts only, so you have to find a friendly one for a few bits and bobs, its where i got my first multimeter, an old avo , but the ranges were made for industrial electricican use, not low voltage, tandy was a revelation when i think we got one in about the mid 80s.

[@Mathozi]

How can i do it on myDVD

[@BitBerlin]

I live in Germany. I'm used to calling these RCA/Cinch connectors "Bananenstecker" (= Banana connectors). Don't ask me why. seems be some remnant artifact from way back when phone operators were using plugs to switch phone connections on a switchboard. I only use Cinch when shopping around because it specifically means this type of RCA connector. Where as Banana connectors refer to a bunch of similar connectors. The whole Connector terminology landscape is a whole clusterfuck. A mish mash of English and German official names and their colloquialisms. Sometimes it's hard to know WTF you are talking about. I prefer the Englisch terminology. #WelcomeToGermany

[@pauldow1648]

Will this charge your phone while it is on ?

[@unbekannter_Nutzer]

Via the audio plug? Most probably not. :)

[@MrSherifmattar]

Great idea 💡💡

[@cannabine413]

wow i wish i had someone like you near me i would pay you to do this with my sony

[@PGE564]

Hmmm, how about adding Blue Tooth to an old Sansui amp?

[@hkaditya]

Buy receiver

[@Michalmas64]

In Poland we also pronounce "cinch" in the same, incorrect way ;P - so that name is used outside Germany ;).

[@engineerdeluxe]

Cinch-Klinke-Kabel.... wichtigstes Kabel ever ❤😉

[@jo31b]

Those USB chargers can be crazy noisy on both HF and VHF frequencies even when the battery is fully charged.

[@danieldudas9026]

In Vojvodina, Serbia it's also called chinch.

[@dablife8321]

How you remove speakers from radio

[@Astolfo2001]

Nokia (yes, the same Nokia [in]famously known for their mobile phones) made and sold hifi stereo equipment? I bet they must be ultra durable then. It's a shame that they never got released here in the US though.

[@arthurvanparijs6121]

We also say cinch in Belgium

Will you offer a custom AUX installation service if I just mail my car stereo to you? And if not, why?

[@EricJones]

This would work well with a Chromecast Audio in place of the Bluetooth too.

[@overbuiltautomotive1299]

very good i need to do this

[@HelloKittyFanMan]

"...Laptop or computer"? FFR (for future reference), that didn't make sense. What _is_ a laptop, supposedly, if not a computer itself (pre-emptive defense: with that as their original primary function, as opposed to a smartphone, so don't go there about what smartphones are too)?
