#Arduino Flash Trigger - Update 1
Here are two pictures of the first prototype board for the Arduino flash trigger. Things that I have changed from the last scheme are:
- removed triggering 3.5mm female connector, instead I have 3-pin connectors to connect wires on one or two flashes
- added 6 pin programming header so that I can program Atmega chip without removing it from the board every time
- added 3 pin jumper header for power selection (usb/external)
Here are two pictures of a fresh etched board, not perfect on the corners because of bad mixing of the acid but good enough for the first attempt.
P.S. Updated schema coming soon.
