I have a PlayStation Gold wireless headset, for chatting with people I play video games with. It usually recharges via a USB cable but I wanted a recharging stand for it, so that the USB connector does not suffer from wear-and-tear and I don’t have to worry about managing yet-another-USB-cable.
The stand itself is made of 9mm thick clear acrylic plastic, laser cut and laser etched by Ponoko. I used copper foil tape to make a connection from a DC barrel jack to the headset. The headset has two patches of conductive velcro that connects with the copper foil tape. Inside the headset, I installed a simple lithium battery recharging circuit. There is a LED that will glow red during recharge, and glow green when the battery is full.
The circuit is made with spare parts soldered to a piece of protoboard. The circuit itself is protected from all sorts things. Self resetting PTC fuses prevent damage to the power supply and the circuit. A schottky diode to prevent damage from reverse polarity. A zener diode provides a crude over voltage protection. A TVS diode (not shown in circuit diagram) is used to protect against static electricity. One way that I could’ve improved the circuit is to use a full bridge rectifier.
In simple words, I can’t break it by placing it on the stand backwards, or by using the wrong wall-wart, or by short circuiting anything, or by having too much static electricity from my hair.
