Teardown: The Audi R8 V10+

Now in it’s second generation, the new Audi R8 regains its mantle atop Audi’s storied performance car portfolio. Of the several models offered, I’ve chosen the flagship R8 V10 Plus. But since I couldn’t get my hands on a real R8, I’ve chosen the next best thing: an RC car.

The teardown took about 45 minutes in real time (20 of that was spent driving the car around the studio), and it was very simple aside from the odd glued and taped bits.




Yamaha PortaSound PSS-16

This is an old keyboard that my family has had for many years. I decided to tear is apart because I was curious what kind of technology existed inside of it. I came to find out that there actually wasn’t as much internally as I would have thought and it only required a screwdriver to disassemble.




Here is the list of what I found:

  1. Lots of screws (actually it was all screws to take it apart)
  2. Multiple touch sensitive boards 
  3. Rubber molded buttons
  4. Two speakers
  5. A metal plate and plastic molded keys, as pieces of the part you play on.
  6. And last but not least the brains of the system, which includes the YM7137-3D chip made by Jotrin.

Everything Together


Unfortunately, I couldn’t find anything about some of the board components. Maybe it’s partially because they are built by the company and the schematics are not released. All the boards said Yamaha on them.

In conclusion I think this was an exciting project. It gave a good deal of insight into what went into a small keyboard eighteen years ago. Today, I’m guessing that a bunch of these parts would probably be smaller and able to fit better into the casing. (There was some bending of parts on the motherboard to get them to fit). I look forward to trying this process again on something else in the future.

Zoomer Zupps Teardown


She’s Bubblegum.  Well, she was.

  1. Outer shell: Plastic 1 | Plastic injection molding
  2. Speaker component: Plastic 4 | Structure between the speaker and the outer shell
  3. Speaker: Includes magnet, copper wire | Produces sound
  4. Cover for eyes
  5. Batteries
  6. Sensor: Copper
  7. Chipboard: located inside the dog’s head
  8. Chipboard for nose
  9. Rubber cushion for nose button
  10. Structure holding together all components in head: includes LEDs for the eyes
  11. On/Off chipboard

The plastic shells are made by plastic injection molding. Then, all parts are assembled, wires soldered into boards and plastic parts screwed in.




I took an interest into how the eyes of Bubblegum are designed. Instead of one piece of solid plastic shell with an iris painted on, her eyes resemble the interface of a digital clock. I thought this was rather appropriate for a battery-powered dog, as this design choice makes the dog look even more like a robot dog. One might even say that the eyes are the single visual feature that makes this toy undeniably a robot.

Another interesting feature I found was a sensor inside the head. The designer might have come up with this design based on the insight that children like to pet and stroke dogs. Putting the sensor there so every stroke or tap produces a different response was rather fitting for a toy like this.

Teardown – Nintendo Zapper

tear down 1

Nintendo Zapper

I bought it in the E-waste Warehouse in Brooklyn. The Zapper allows players to aim at the television set display and “shoot” various objects that appear on the screen such as ducks, clay pigeons, targets, cowboys, criminals or other objectives. The Zapper is used on supported NES games, such as Duck Hunt and Wild Gunman. The Zapper could also be used on the title screens of games to move the cursor—done by pointing the device away from the screen and pulling the trigger—or starting the game (pointing at the screen and pulling the trigger).

This gun is pretty classic and stylish. When people hold it, it seems like you are holding a real gun, perhaps because of the Bob-weight. There is several components in it. The trigger structure is interesting and through the Teardown I realized this structure. And the trigger connect the sensor (kind of flip-floph) and activate the circuit board and laser light.

Walkie Talkie – Teardown


I chose this Walkie Talkie for kids to teardown. I did not expect the insides to be complex, although I thought the way some of the components were fixed to the walkie talkie’s main body was rough (some taped parts and cables). However this is a children’s toy and was probably design to be as affordable as possible, without putting much emphasis on the quality of materials, manufacture or function.

I used only a screwdriver to take it apart and did not need to break any parts in order to see all the components. Here are some of the parts inside the walkie talkie:



TEAR-the guitar-DOWN



The first thing I love is the simplicity of the parts of the Guitar. The assembly of the plastic connector parts is easy and none of them have complex mechanisms. These parts are snap connectors. At times when complex systems and parts were needed in order for something to work, the designer decided to add more but still simple parts.
As the retail price for the game is low – $8.50, it seems like they chose easy assembly over minimal material.
The other thing I like are the silicon rubber conductive button pads. This is the first time I’ve seen such a thing. It’s form at different locations is what makes it fascinating! When pressing a long button – in this case – the Hero Power button, 3 button pads are used to make it work. Whereas, the tiny buttons like – the Pause button – only use 1 conductive button to complete the circuit.
