== Introduction ==
 
General information and tips about PineBuds Pro.
 
=== Buttons/touch sensors ===
 
==== Buds ====
One capacitive touch sensor is located on the outward facing surface of each bud near the logo.
 
==== Charging case ====
When the buds are shipped they may have stickers covering their contacts, preventing contact with the charging case. These need to be removed before the buds can be used.
 
The charging case has a reset button in the center under the lid (between the seats for the two buds,) which is hooked to the ThinkPlus Semi SY8821 integrated circuit and that button resets it from the safety off mode.
 
=== Cleaning ===
 
PineBuds Pro only have IPX4 rating, so they are only splash-proof and cannot withstand immersion in water. Clean the charging case inside and out with a damp microfiber cloth. Inside, be careful near the pogo pins! The cloth easily sticks to them and may tear them. You can use a microfiber cloth at the end of a stick to immerse of the buds, but a cleaning tool made for this can help. When cleaning the buds, carefully remove the tips, place the buds on a damp microfibre cloth and one by one wipe it from all sides. Be careful with the protective mesh. If there is dirt in the mesh, you can carefully clean it with the brush of the previously mentioned tool. Wash the tips with soap and water, but be careful, they easily drip from your hand to drain. After drying them, carefully put them back to the buds.

The PineBuds Pro

The PineBuds Pro are open firmware capable ANC wireless earbuds. Some of the notable features include their light weight, 3 Microphones, ANC (Active Noise Cancellation), ENC (Environment Noise Cancellation) and high fidelity 6mm speaker. It is a fully community-driven side-project which anyone can contribute to, allowing you to keep control of your device even though hardware is proprietary.

Introduction

General information and tips about PineBuds Pro.

Buttons/touch sensors

Buds

One capacitive touch sensor is located on the outward facing surface of each bud near the logo.

Charging case

When the buds are shipped they may have stickers covering their contacts, preventing contact with the charging case. These need to be removed before the buds can be used.

The charging case has a reset button in the center under the lid (between the seats for the two buds,) which is hooked to the ThinkPlus Semi SY8821 integrated circuit and that button resets it from the safety off mode.

Cleaning

PineBuds Pro only have IPX4 rating, so they are only splash-proof and cannot withstand immersion in water. Clean the charging case inside and out with a damp microfiber cloth. Inside, be careful near the pogo pins! The cloth easily sticks to them and may tear them. You can use a microfiber cloth at the end of a stick to immerse of the buds, but a cleaning tool made for this can help. When cleaning the buds, carefully remove the tips, place the buds on a damp microfibre cloth and one by one wipe it from all sides. Be careful with the protective mesh. If there is dirt in the mesh, you can carefully clean it with the brush of the previously mentioned tool. Wash the tips with soap and water, but be careful, they easily drip from your hand to drain. After drying them, carefully put them back to the buds.

You need:

  • A microfiber cloth
  • A cleaning tool like this or this

Community projects

The following community projects are currently being worked on:

  • Wireless charging, bringing wireless charging to the PineBuds Pro case using vacant contacts
  • Silicone case, a transparent silicone case with an improved grip to the case
  • Straps, to add straps to the PineBuds Pro

Disassembly / Assembly

Disassembling the charging case:

Note: A video tutorial regarding the disassembly can be watched from Linux Lounge here
  1. First open the lid and then try to press the case from the front edge with a plectrum or a thin card. There are two clips on each side. Soon the case will snap open.
  2. Carefully unscrew and remove the PCB from the case.

Assembling the charging case:

Note: A video tutorial regarding the assembly can be watched from Linux Lounge here (at the 3:50 minutes timestamp)
  1. Screw the PCB back into the place.
  2. There is plenty of space, glue the coil to the bottom of the case.
  3. Close the charging case.
