Prototyping an arduino based macro focus stacking contoller.
Stackduino is an Arduino based controller for automating focus stacking.
A stepper motor moves the camera/ subject between pictures and the controller sends a shutter signal to the camera to take each picture. For safety, the camera is electrically separated from the controller using opto-isolators.

Ermine Moth Caterpillars
The caterpillars live communally and cover their surroundings with silk webbing to protect themselves and their food plant. This is a sub group of a larger colony of several hundred.
150 images, 14mn spacing.
I’m guessing the ‘tongue’ protruding from the end of the needle would be retracted in a living specimen and then protruded into the body of the victim once it’s pierced. Do they turn their food into soup like spiders?
Males are required to present a dead insect to the female as a mating gift. It’s a touching moment.
