DIY'ed High Speed Photography Controller
This is the controller I designed and fabricated (it is not that easy to solder surface mount components). It has three inputs, namely, X, Y, and A (bottom one) and two outputs, one for water valve (or camera in cross beam detection mode) and one for flash. The knob is for changing various parameters, it is a rotary knob, so it rotates forever, unlike potentiometers. The red button is used to change edit mode and select parameters to change (by the knob).
It has following functions:
1. Water collision mode. This mode allows me to specify number of water drops, delays between drops (up to first four drops) if more than one drop, (unified) drop size, and delay to flash after the very first drop is carried out.
2. Delay mode. This mode allows me to do time delay between triggering and flashing. Input can be either X or Y, but not A.
3. Sound Trigger mode. This unit has an amplifier with amplification around 500. It can detect weak signals, such as sounds, photo-detector pairs, etc. The input is A (for Amplified) and I can change delay between detection of signal and flashing.
4. Input pulse measurement mode. This mode allows me to measure pulse width on either input X or Y. I have used this mode to measure duration of a few electronic flashes, namely, SB600 and YN560.
5. I also can trigger a camera when both X and Y are triggered at same time for cross laser beam situation, but so far, I am not able to get rid of camera shutter lag, so this feature might not be useful.
Anyways, I am waiting for an aluminum case for it. Yeah!!!
