Bop It BLAST Teardown

Pre-Teardown

What I teardown is bop it. It was originally a talking and glowing guy, and the way to interact with it was mainly pressing the center part, pulling the blue feet and twisting the green feet. A round head contains the most important circuit boards and springs, and its two feet are mainly where batteries, some extended wires, buttons, small circuit boards, and mechanical parts are placed.

The Teardown

I first removed the shell on one side with a screwdriver and found that the battery is on its legs, not on its head. The buttons are located above the left leg and touch a small circuit board.

When I removed all its shell, I can see that the main chip is placed on its head. On the head chip board, there are various circuits extending to its legs. The ports of the circuit are connected with battery, buttons, lights and beads.

Next, I started to disassemble its head. When the plastic fixing piece was removed, a spring jumped out. This is why the head can be pressed.

When I further disassembled its head, a speaker was pasted on the back.

At this point, it still has the other half of the head that I haven’t removed it yet. You can see that the orange button corresponds to the button on the chip.

There is still a spring inside this half of the head, and a red lamp bead behind it.

Next is the teardown of the two feet, I will use a video to illustrate.

Manufacturing technique used to make it

Injection molding

Chips Sheet

  • Debounce time setting(when you press on your standard mechanical switch, it hits the contact and then it bounces briefly from momentum of you hitting the key/switch, sometimes the momentum can be enough for the contacts to touch again and cause a double click. Debounce time is basically and amount of time that the switch doesnt register another click.)

Tools used

  1. Screwdriver
  2. Scissors

Design elements I am interested in

  1. Put the battery on its legs not in its head. (In addition to the realization of the function, the internal parts distribution must also consider its appearance. Its legs have just enough space for the battery, and it is easier for users to teardown.)
  2. Use the user’s pull and twist to press the button. (Make full use of the user’s behavior and use mechanical buttons to save costs.)
