ESP32 & Sensors - Session 2: Soldering Foundations

​Building on Session 1, we're getting hands-on with the fundamental hardware skill: soldering. This is where components become circuits, and circuits become devices you can actually use.

​What We're Doing:

• ​Soldering fundamentals - technique, tools, safety

• ​Practice connections: wires, headers, through-hole components

• ​Prepare ESP32 boards for sensors and peripherals

• ​Solder sensor connections for our chemistry sensing projects

• ​Build confidence for future projects (mesh networks, voice assistants, custom robots)

​The Format: Peer exploration continues. Stewart brings soldering stations, components, and years of burn marks. You bring curiosity and steady hands (or shaky ones - we all start somewhere). We'll practice together, troubleshoot together, and prepare our hardware for the year ahead.

​What You'll Leave With:

• ​Hands-on soldering experience

• ​At least one completed ESP32 board ready for sensors

• ​Understanding of what makes a good vs. bad solder joint

• ​Confidence to solder your own projects

​Who Should Come: Cohort members from Session 1 preferred. New members welcome if space allows (max 6 people).

​Bring:

• ​Your ESP32 from Session 1 (if you have one)

• ​Laptop

• ​Any sensors or components you want to connect

• ​Safety glasses if you have them (extras available)

​Safety Note: We'll work with hot tools (300-400°C) and small amounts of solder fumes. Ventilation provided. Not suitable for those with respiratory sensitivities.
