    Retro cassette player gets modern MP3 playback and RFID functionality

    Arduino Team — November 9th, 2020

    When creator mattb_138’s parents were cleaning out their house, he came across an old cassette player and decided to upgrade it with MP3 capabilities and an RFID interface.

    The newly-enhanced device uses an Arduino Nano for control, along with a DFPlayer Mini module to play songs stored on a microSD card. An RC522 reader enables him to select tracks based on RFID cards, printed with their appropriate album art.

    The cassette player’s internals are kept largely stock, using a potentiometer to adjust the volume of the original speakers. Two buttons are also implemented with long and short press functionality, allowing for pause/play, skip, shuffle, and selection between A/B “side” of each card.

    Build your child a wooden MP3 player for $100

    Arduino Team — December 30th, 2019

    If your young child wants to listen to music, what better way than a beautiful wooden MP3 “radio,” with an array of buttons that select the album? After being inspired by a similar commercial product, Redditor “DerThes” decided to make such a device for a fraction of the cost using an Arduino Uno for control, along with a Music Maker Shield to play tunes off an SD card.

    The toddler can select songs from a grid of 16 input buttons, which are sent to the Uno via a pair of shift registers. There’s also a “parent’s mode” with the ability to choose from up to 99 albums, and a volume knob for… adjusting the volume. 

    Finally, the unt features a beautiful enclosure made out of oak and black walnut, with corners softened by dowels to reduce collateral damage “after the player has gone airborne.” More details can be seen on Imgur here and on GitHub.

    This is an easy to use MP3 player for small children. I made this for my 2 year old for Christmas. Each of the top 9 buttons will play an album. The black buttons on the bottom are prev – play/pause – next. The player also supports an alternative playback mode that can be activated using a special key combination. That combination will turn the buttons into a 10 digit input matrix allowing playback of up to 99 albums. That way the player can be used by parents as well. 😉

    See GitHub for more details, the schematics for the button PCB and the firmware. https://github.com/MichaelThessel/arduino-stoerbert

    This is heavily inspired by Hoerbert: https://en.hoerbert.com

    When I first saw the Hoerbert at a friends place I wanted it for my child. After I heard of the $400 price tag I knew that I needed to spend 50 hrs and $100 to build my own.

  • Cassette MP3 Player Tutorial by BrittLiv

    Cassette MP3 Player Tutorial by BrittLiv

    Reading Time: 5 minutes
    Picture of Cassette MP3 Player

    In this instructable I am going to show you how to house a MP3 player in a cassette tape. I had the idea to build this quite some time ago, but while I was still waiting for the parts to arrive, instructable member lonesoulsurfer posted his version here.

    So I decided to concentrate on other stuff and somehow forgot about it. After moving recently, the parts fell into my hands and decided to give this project an other shot, since my approach is quite different from lonesoulsurfers. My idea was to actually use the cassette tape wheels as buttons to select the songs and adjust the volume.

    The cassette I used for this was broken and I decided to give it a new, more modern life.

    Btw. I know that you can buy cassette MP3 players e.g. here or here, but I wanted to build one that looks completely like a normal cassette.

     

     

    Step 1: What you need

    Picture of What you need

    Materials:

    • Cassette (that is held together with screws)
    • Block USB MP3 Player (e.g. from amazon.com or a lot cheaper from ebay)
    • Glue (jb weld, faster setting 2 component glue)
    • Enameled copper wire (e.g. from amazon.com)
    • Two M3x20mm screws
    • Micro SD/TF card (max. 8GB)
    • Solder
    • 4 miniature snap action switches (e.g. from digikey)
    • Shipping labels (if you would like to change the label)

    Tools:

    • Soldering iron
    • Rework station (not a 100% necessary, but certainly helpful)
    • Sharp knife
    • Screw driver
    • Diamond file

    Step 2: Take the MP3 player apart

    Picture of Take the MP3 player apart

    Start by taking the MP3 player apart. The bottom can easily be lifted off with anything sharp. There is a single screw next to the SD card, holding the board in place. Unscrew it and take everything out of the shell.

    Remove the sticker from the buttons and unsolder the battery. You will also have to remove the audio plug, the on/off switch and the micro USB jack. A rework station is certainly helpful in fulfilling this task. Make sure to keep all the unsoldered parts, you will need them later on.

    Step 3: Preparing the cassette

    Picture of Preparing the cassette

    IMG_3292.jpg

    Take the cassette apart in order for it to house all the components. Afterwards you will have to create the openings for the headphone plug, the USB jack and the switch. I decided to place the opening for the audio plug at the side of the cassette, so that I would be able to carry it around in my trouser pocket and to use the two already existing holes at the top of the cassette for the other two components.

    Step 4: Creating the push buttons

    Picture of Creating the push buttons
    IMG_3282.jpg
    IMG_3399.jpg
    IMG_3505.jpg
    IMG_3512.jpg
    IMG_3516.jpg

    I decided to keep the magnetic tape, because removing it felt as if something was missing. Since I couldn’t fit it in there entirely, I had to cut it to the correct size. To prevent the tape from unreeling, I used quick setting two component glue, as shown in the pictures. Before you do so, cut off an around 10 cm long piece, since you will need it later on.

    Cut a small slot into the wheels and glue the screws into them (You don’t have to cut the screw heads off, like I did). You can of course use any other type of pin, but I found that a M3 screw has the perfect size.

    As you see in last step, the space is very restricted. You will have to cut some of the plastic from the wheels in order for them to fit (as shown in the pictures). Remember that you will have to move them later on, so make sure that you are able to do so. Afterwards glue the miniature snap action switches in place so that they can be operated by the pin. Connect them to the board, as shown in the pictures. If you have not worked with enameled copper wire before, don’t worry it is quite easy to use. Simply use solder to burn the protective layer away. If you are still unsure, it is explained in this video.

    Step 5: Assemble everything

    Picture of Assemble everything
    IMG_3543.jpg

    Solder everything back in place as shown in the picture. Make sure that the SD card fits and that everything moves fine. Use the JB weld to hold everything in place.

    After the JB weld is set, glue the magnetic tape you prepared before back in place, as shown in the second picture. Make sure, that the wheel can sill be moved without any interference. Use the 10 cm piece of tape that you saved before and glue it to the two small wheels at the bottom of the cassette.

    Screw the cassette back together and change the label, if you want to. Songs can by added with an USB cable, so you don’t have to open the cassette every time.

    I added a pdf of the label I made so that you can make your own Guardians of the Galaxy version. Upload the Guardians of the Galaxy: Awesome Mix Vol. 1and you are ready to safe the universe.
