Mightyohm gave a broken phone handset new life in the form of bluetooth functionality – by repurposing a discarded, semi-functional headset –

Upon receiving it, I proceeded to rip the headset apart, interested to see what was inside. I found a fairly simple PCB with a discrete bluetooth module in the center. The PCB is not labeled, but given that this is an older headset (3-4 years old) most of the connections are large enough to attack with a pencil iron and solder wires to.

This headset was begging for a project.
