wooden handmade dock
I tinkered a wooden charging dock. Therefore i bought pogo pins, a DC power supply. Pieces of wood, glue, solder and needed tools I found in my father's garage
I decided to take:
a 5V/DC power supply with a current of 2000mA and 10W ~10€
Pogo pins: F70211B130G015 by German brand Feinmetall ~ 4€ pair
The pogo pins have a low spring force of 15cN. If I remember physic lessens well and my considerations are true you shouldn't go with much higher spring force. I soldered them on a piece of circuit board and fixed it at the frame. It works great and charges fast as you would aspect with 2A.
It's not that devastating to interchange the polarity - the phone reboots.
