Attached is a photo of my Flash Controller Box up and running. In the photo the mode used was “Fire All”.
Might be able to post photo later of it in use against a wall if the weather allows me (unsure if I have enough sand bags to weigh everything down for shoot). Attached is also a view (unpowered) of the top and a third showing inside the “lunchbox”
The wire in the bottom left is the camera sync lead. The four flash sync leads plug into the four “flying” leads (as can’t get these from Jaycar - had to cannibalise some sync leads to get the female ends.
It currently has four modes 1) fire all flashes at once, 2) fire one specified unit, 3) fire all sequentially with a specified delay between each, 4) fire each flash in turn, cycling through them firing one unit per camera trigger.
It consists of a Yourduino board with a freetronics terminal shield for connections and protoboard space for the analog voltage ladder for the switches (as the lcd onboard buttons were too small), A Freetronics 16x2 LCD Module and a YwRobot 5v 4-relay relay board to switch the flash sync trigger lines. along with 7 m/o push button switches and an on/off switch.
Power is via USB when programming updates and 6v battery cluster when in use.
