Adding Bluetooth to Vintage Headphones @MicrochipTechnology
A great post over on the Pick and Place blog – Jean describes in detail adding bluetooth into a pair of classic headphones. Part 1 describes the design process, including keeping the original manual volume knob. In Part 2, with custom designed PCBs back from China, Jean gets all the components fitted in.
Because I wanted to keep the headphones as much in their original state as possible, without adding holes, I decided to use the original potentiometer for control and volume. This means I had to find a way to detect a press on the potentiometer. For the bluetooth part I will use the Microchip BM62 Bluetooth module. It’s really cheap and has everything already built-in (Bluetooth LE, a serial interface for control, pins for LEDs, a battery charger and an audio amplifier).

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
