Inside A Bluetooth Earpiece - Amazing Parts Salvaged - Free Vibrating Motor+

See how a Jabra Bluetooth Earpiece works & what’s inside as I carefully dismantle and demonstrate the salvage process for some amazing parts. Inside you will get a FREE vibrating motor, FREE mini-microphone, FREE mini speaker (which has a FREE neodymium magnet inside), FREE rechargeable battery pack with attached charging chip and more. I almost forgot to mention, you also get a complete Bluetooth circuit for FREE that is just waiting for use in another project! After I dismantle the earpiece I demonstrate the operation of the vibrating motor which is also known as an Eccentric Rotating Mass (ERM) motor; it’s essentially a mini vibrator. The ERM is roughly the size of an eraser from a mechanical pencil and that makes it perfect for many future projects.

The great thing about taking things apart to salvage pieces is not only the cool, FREE PARTS you can get. It’s also the great opportunity you get to learn how things work which also teaches you how to make other stuff! I often get project ideas from seeing how stuff was built and designed to work. Call it salvaging, dismantling, repurposing, reverse engineering or even trashing stuff… in the end you get some great parts & materials for use in other projects and if you do it the way I do, then the parts are 100% FREE (I get old items from family, friends, acquaintances, etc. and they think I am doing them a favor by taking their “trash” off of their hands). There have been many times that I have been given “broken” stuff that was actually very easy to fix and make work like new with a simple tightening of a screw, reattachment of a wire or possibly replacement of a part. You will be amazed at what people throw away!.. which is why they are usually happy to give it to you for free.

ADDITIONAL INFORMATION ABOUT BLUETOOTH FROM D.I.D.:

Bluetooth is an amazing technology that is a vast improvement over standard use of radio wave or infrared transmissions. Bluetooth works by way of wireless, short range technology for communication. The transmission works in an unlicensed ISM band (ISM stands for Industrial, Scientific & Medical Devices) which runs on a 2.45 gigahertz (GHz) frequency. The actual range is more like 2.4 - 2.48 GHz. This same frequency is used by many other applications such as Wi-Fi, microwaves, baby monitors, garage door openers and more. Bluetooth, however, does not have a major interference issue when it comes to crossing paths with other devices because of the way the signals are sent. The process is called Frequency Hopping (AKA spread spectrum frequency hopping) and it works allot like how it sounds. In short, there are 79 frequencies in the ISM band and Bluetooth devices use a somewhat random pattern of switching around within those frequencies. The primary device is referred to as a master and it sets the timing and pattern which all connected devices mimic. This primary device cycles the transmitted frequency many times per second. Because of this no two non-connected (not paired together) Bluetooth devices will be on the same signal at the same time but if it did happen it could only last for a fraction of a second. You can actually connect / pair up to 8 devices in the same grouping (ex. 1 master and 7 connected devices) which forms a Personal Area Network (PAN), also referred to as a piconet, that operates in a close range circuit. Because the signal is a low power radio transmission the effective range is about 10 meters. This also facilitates that lack of signal interference from other Bluetooth PANs or devices. Newer efforts in the technology continue to improve upon the signal clarity by further reducing the possibility of signal interference. Some such efforts include Adaptive Frequency Hopping (AFH), Bluetooth Interference Aware Scheduling (BIAS) as well as Channel Estimation.
