Picture of DIY Bluetooth Headset (BK8000L Chip) 3D Printed
DSC_0093 (2).JPG

Hi there!

Here i would like to show you how to make your own wireless bluetooth headset. My motivation for doing this project is the fact that there are a lot of bad bluetooth headsets that i bought recently, so by doing my own i can tweak and develop each stuff i would like it to be. Besides, i also have a personal 3D printer which make this project more exciting and even more customizable.

This headset (BK8000L Chip) features are bluetooth 2.1+EDR compliant, A2DP v1.2, AVRCP v1.0 and HFP v1.5 which is not quite amaze me by looking other modules online that supports bluetooth 4.+ such as qualcomm CSR chips. But the end results satisfied me because it just connects quickly, works like a charm, practical, and of course the most important thing, sounds better than i previously bought. Enjoying movies is also possible because the latency of this bluetooth is approx below 100ms. Some test measurement will be attached below

Given the fact that this project is quite difficult for beginners, i suggest you to be patient when doing this because this requires knowledge like 3d printing, pcb making, soldering, and 3D modelling. Let's dive in!

Step 1: Prepare the Stuffs!

Tools:

  1. 3D Printer
  2. Laserjet Printer
  3. Screwdriver (-)
  4. Solder
  5. Scissors
  6. Iron
  7. Multimeter



Materials:

  1. BK8000L Chip (From Aliexpress, etc.)
  2. Wired Headset/Earphone (Get the best that you can afford)
  3. Lipo Battery 260mah (customizable)
  4. TP4056
  5. Push Button (smd)
  6. Toggle Switch (smd)
  7. Resistor 110 ohm size 1206 (3x 330 ohm paralleled)
  8. Resistor 10k for TP4056 current treshold
  9. Photo paper
  10. PCB Board (1mm thickness)
  11. Soldering tin and flux
  12. PLA Filament
