Would you make a DSLR USB shutter control cable for me?


Recommended Posts


After trying to make USB shutter control cable for an EOS 20D and failing (soldering skills and eyesight failing) I am asking the community to help me finish this. I already have an FTDI USB to TTL cable for the job and I have converted the 20D shutter control to 2.5mm female audio jack. The circuit needed  is like this one


except it will be driven by the GREEN/BLACK wires of the FTDI cable instead of the pin-7/pin-5 of the serial port in the diagram. If you can help, please get in touch.
