This is Hacker Public Radio Episode 3,794 for Thursday the 16th of February 2023.
|
|
Today's show is entitled Retro Cariochi Machine Restored.
|
|
It is hosted by Archer 72 and is about 8 minutes long.
|
|
It carries a clean flag.
|
|
The summary is I fix the cassette tape mechanism to a resale shop Cariochi Machine.
|
|
Hello this is Archer 72, welcome to another episode of Hacker Public Radio.
|
|
In this episode I found an NTEX Electronic Singing Machine Cariochi Model 1820 in the
|
|
thrift shop.
|
|
From worthpoint.com it was made in Taiwan in the late 1970s to the early 1980s.
|
|
It incorporates an 8-track player and a cassette tape recorder.
|
|
It also uses the Bucket Brigade Device, BBD Echo, Power Supplyed by 120 volts AC.
|
|
It also uses 10 D cell batteries or alternatively 12-15 volts DC.
|
|
As a side note, NTEX made handheld games and they have manuals on the internet archive
|
|
and I'll leave a note for that.
|
|
The first thing I noticed when I tested this machine in the store is that the control
|
|
knobs were pretty noisy.
|
|
So I picked up some contact cleaner and worked especially the volume knob.
|
|
So that helped a lot with consistent playback so it wouldn't be static when I turned
|
|
the volume up and down.
|
|
Besides that the 8-track tape did play right off but the cassette side of the machine
|
|
did not.
|
|
So I figured based on what John Colp had said in a previous episode about cassette players
|
|
that the belts might be bad.
|
|
There were about 8 screws holding a panel in to access the back and when I first looked
|
|
in I saw that there was only one belt in the cassette side and it was just hanging there.
|
|
Initially just thought I would need one set of belts so I ordered those off I Amazon.
|
|
To get to these belts on either side there were 3 screws holding the tray in place.
|
|
In other words the assembly that held both the 8-track and the cassette electronics together.
|
|
The two thinner belts were easy enough to install without pulling the assembly further
|
|
apart.
|
|
When the tape player still didn't turn I realized that there was a flat 4mm belt that fed
|
|
around the flywheel and also to a spindle which looking back I probably should have cleaned
|
|
up with alcohol because in this porting picture you'll see that it's a little bit gummy.
|
|
There were 3-4 screws holding the cassette assembly together to where I could replace the
|
|
flywheel belt.
|
|
I had to be careful getting it back together though because there were 3 pulley wheels
|
|
in an assembly that led to a switch on the PCB and also when I put it back together
|
|
I couldn't forget to put back the connecting rod to the cassette tray and before I started
|
|
taking this apart there was a cover for the cassette tray that was held in by two thumbs
|
|
screw.
|
|
The final check to make sure the cassette side turned freely now that I have it put back
|
|
together I can show you what the 8-track side sounds like.
|
|
Unfortunately I can't actually play music off of it to show you because it's copyrighted
|
|
but I can demonstrate the mechanism and the button that changes the tracks.
|
|
I can play something from the cassette side.
|
|
I pre-recorded this from the free music archive.
|
|
The title is Cyborg Lost by Modern Monster.
|
|
Now I'm ready to capture audio from the line out which I noted on the back that there
|
|
were both the line outs were red in color so that kind of indicates that it was made
|
|
quite a while ago before the standard became red on the right and white on the left.
|
|
I used a sabrent audio capture device because on the netbook that I repurposed from a previous
|
|
show it only had a single channel for the microphone input and also this capture card captures
|
|
at a higher bit rate and it's unknown as to what the microphone input bit rate was on
|
|
the netbook.
|
|
I'm using a record to capture the flack output and I thought it would be a nice play on
|
|
words to name the script capture the flack.
|
|
If you have an idea what this is a play on words from then feel free to leave a comment.
|
|
This is captured using the a record utility.
|
|
It names the file with a time and date stamp and the command is as follows.
|
|
A lot of audio capture.
|
|
A record L find device to use this works for finding the microphone input or the USB external
|
|
sound card.
|
|
Soundcard system fault code and card equals device USB audio device USB audio default audio
|
|

|
|
Capture the flack.sh.
|
|
File equals dump, dollar, date plus percent f percent h percent m percent s sabrent sound
|
