I've begun working on a speedlight flash unit that will be attached to the frame. My main reasons for wanting to make a couple flashes for it is convenience and cost. It will save me from having to readjust them every time I wish to use the insect rig and save me some money. I removed a bunch of capacitors from disposable cameras to make a capacitor bank for the flash. The tube I am using is from Electronics Goldmine and is about 10". I am also using a trigger coil from them. The flash works well manually triggering it. My next step is to add an IGBT to control the flash duration. This will also short the trigger coil to a capacitor to initiate the flash. This allows me to control the flash duration with 1 pin on a micro controller.
