This is my first tutorial on this site, so feel free to give me some feedback or clues what can be done better 😉
Today i will show example project with photographing some paints splashes using PiXPi with speaker/vibration module.To do this you need flash lamp and camera of course, also because we will do “high speed photography” You will need darkroom = room without external light.
Okay so if we got scene ready, no we will need to program sequence usin app, but first connect PiXPi to power supply and wait for it to boot up, it will make sound to tell it’s ready.Next open app and, create new project, setup choosen port as output, and create sequence:
-camera shutter control should be in “bulb” mode
-flash should be set on lowest possible power if we want to freeze motion perfectly, this is because flash duration is shorter on low flash powers
-any external light is undesirable during running sequence, this is because camera is in bulb mode so from beginning of script it has open shutter, and external light will reduce sharpness of image, proportionally to external light power, so do this in night or find place where You can cover windows etc.
