Nikon BULB mode USB control cable
This is my version of a USB corded shutter control based on the ccs_hello's CN forum user project (here the reference thread).
List of components:
- MD-DC1 compatible connector and cable (added a 3.5mm stereo jack for multi-purpose use)
- BC557 PNP transistor (be aware, this transistor has different pinout with respect to the transistors suggested by ccs_hello in the above CN thread, the BC557 is however equivalent to the 2SA1015 regarding functional characteristics)
- 1N34 germanium diodes (x2)
- 4.7K resistor
- PL2303HXD USB to TTL 6 pins module
