Assignment requirements
Group assignment
- Do your lab's safety training
- Characterize your lasercutter's focus, power, speed, rate, kerf, joint clearance and types
- Document your work to the group work page and reflect on your individual page what you learned
Individual assignment
- Design, lasercut, and document a parametric construction kit, accounting for the lasercutter kerf
- Cut something on the vinyl cutter

1) Introduction
My main goal: survive
2) Equipments and materials
Digital multimeter PR-75
Type: Portable digital multimeter. The PR-75 is a general-purpose handheld digital multimeter designed for basic electrical measurement tasks in electronics and electrical work
Main features:
DC / AC Voltage Measurement up to 600V, Resistance Measurement (Ω), Continuity Test with Buzzer, Diode Test, Current Measurement (mA and 10A), Digital LCD Display, Manual Range Selector
Practical use:
Verify power supply (3.3V and 5V), check continuity between traces, and rule out short circuits before taking measurements with an oscilloscope
Digital oscilloscope (GW Instek GDS-1152A)
Type: Two-channel digital oscilloscope (150 MHz, 2-channel model) for electronics labs. It captures and stores waveform data, letting you view, measure, and analyze electronic signals visually
Main features:
2 channels (CH1 and CH2), autoset function (for quick signal adjustment), VOLTS/DIV and TIME/DIV controls, trigger system (for signal stabilization), waveforms and measuring values such as voltage and frequency
Practical use:
Verify signals over time (for example, a square wave or a PWM signal), test: microcontroller's output pin, digital signal (square wave), microcontroller code and pins
