LIS753 - Exercise 1

Extending the life-cycle of an electronic shaver for under 5 dollars. - By Humberto E.

Introduction

One of the greatest pollutants of our generation and most difficult to recycle is e-waste. The amount of electronics such as cell phones, televisions, tablets, computers, and plenty of more devices that are treated as e-waste has grown exponentially in our society. Unfortunately, most of these electronics are discarded due to their built-in obsolesce or because the repair cost is greater then the actual device. As individuals there are plenty of ways to help with this issue. I hope that you find my (small) contribution useful.

The Project

Philips Norelco BodyGroom Trimer, battery replacement. In this project I will provide step by step instructions for how to replace the internal battery for the trimer, and list the tools and the parts you need for the repair.

Tools and Parts:

• Small Screwdriver
• Magnifying Glass (optional)
• Needle Nose Pliers
• Electrical Tape
• Soldering iron (optional)
• AAA Ni-MH Rechargeable Battery

Steps:

1. Remove the trimmer head and locate two small screws.
2. Using the screwdriver, proceed to remove the screws and the metal clip.
3. Eject the two chrome panels from the housing by pushing with your thumb. Slide out one at a time.
4. Locate and remove four screws from the center of the trimer that hold the on/off controller.
5. Remove the plastic cover using the needle nose pliers.
6. Swap the battery. You can use electrical tape to reattach the two wires to the battery or solder the wires to the battery.
7. Proceed with the reassembly. Test the unit and make sure it is charging when in the charging cradle.

Congratulations! Give yourself a pat on the back. Not only have you extended the life of your trimer, you are also contributing to the reduction of e-waste.
