Intro: Giving Teddy His Voice Back - Repairing an Old Teddybear With an Audio Recorder

It must have been just before Christmas, when I went for a walk with my dad and saw this teddy bear in the shop window. He could listen, speak and let his heart shine. I was immediately enthusiastic and wanted to have it. Santa Claus meant it well with me and so the teddy bear lay under the Christmas tree (As you can see on the photo above ^^). I was overjoyed with my gift. :)

Over the years and my burgeoning curiosity as devices work, the electronics of the bear unfortunately fell victim to the same.

Despite my age, I still love the little guy and associate it with a positive memory. Meanwhile, I'm a bit older and experienced in dealing with electronics. Time to undo my act ...

Step 1: Tools and Parts

Tools:

  • Soldering iron
  • Hot glue gun
  • Cutter
  • Screwdriver
  • Pliers
  • Needle and Thread
  • Scissors

Parts:

  • 1x ISD1820 Soundrecorder Modul
  • Case for Soundrecorder Modul
  • Some Prototype circuit board
  • 1x Batteryholder (with On/Off Switch)
  • 4x Tactile Switches
  • 1x Red Led
  • A little two-wire cable
  • Socketstrips and Sockets
  • Teddybear fabric

Step 2: Opening and Removal of the Old Electronics

Since I do not really have any sewing experience, I have decided to open it below. Here you should see mistakes made at least. :x

After removing the cotton wool, I turned the fabric over and removed the old buttons and the heart. As you can see, the old buttons have been fragile due to their age.

Step 3: Closing the Holes and Cracks

After a long bath all holes and cracks were closed.

Since there was a lot of damage on the front, he got some sort of a mane there. I think that suits him very well. :D

Step 4: Electronics

First, I worked on the housing for mounting the board and then screwed it in.
Since there was only one pin for Vcc, but more was needed for the buttons and battery, I made a small strip.

Then I removed the onboard LED and soldered to the corresponding solder points a socket strip. Here you can connect the Led from the heart later.

After I knew where the cables came in the case, I cut / drilled corresponding cutouts in the lid for them and the microphone.

Since the enclosed speaker was too quiet and too big for me, I exchanged it for a smaller one from my crafting box. To make it a little louder and protect, I then stuck it in a film can, which I had previously edited a little.

The old light bulb was removed from the heart and replaced with a small red LED.

I tried to make the buttons as big as the old ones.

Step 5: Attaching the Buttons and Led

With hot glue, the buttons were glued to the individual paws. The heart was also clamped again.

So that the cotton does not get stuck on the circuit boards / solder joints, I covered them with a piece of cloth, which was also glued.

Now I was able to put the cotton back in the teddy bear and help him to his old form. :)

Step 6: Assembly

The top two paws I have assigned to the recording function, the lower right with play-once and the lower left to play-while-pressed.

The cables were now connected accordingly and to prevent them from pulling out of the sockets, I secured them with hot glue.

After this the case could be closed and everything stowed away in the teddy.

Step 7: Finish!

The work has paid off, he listens, speaks, and the heart also lights up again. :D

    Oh you had to operate on him via his bottom. I feel so sorry for him. LoL

    Any time you can bring back such a memory, you did good. Make sure you pass it on to some other caring kid. They can enjoy it as well... Thumbs Up!

    Yes, but I was able to sew it well again and as you can see he can sit on a chair again. ;D One day I will definitely try to find a child that can enjoy him. Until then, he will continue to keep me company. :) Thank you very much!
