TBD:

• start button/tumbler;
• better/faster stop mechanism;
• replace wire hell with custom PCB shield;
• bigger motor;
• better on-shaft fixation;
• replace kolhoz.

Machine for determining the fatigue strength of samples with different patterns (so-called "living hinge", which makes sample exert flexibility) produced using a laser machine.

Hardware:

• Amperka Iskra Neo (Leonardo);
• Amperka Motor Shield;
• Amperka Troyka Shield;
• Hall sensor (involved into counting cycles);
• Amperka Quad Display.

Features:

• autamatic cycle counting;
• automatic stop (altough with delay).

Grasshopper definition was designed to make it easier to create different patterns:

The process of generating new samples:

If you wait long enough it breaks (either sample or machine):
