Build a home wet lab with AI as your lab partner

Overview

DIY biology is having a moment. People with no formal lab training are running PCR on their kitchen counters, extracting DNA from cheek swabs, and using large language models as 24/7 lab partners. This course walks you through setting up a minimal home wet lab, working safely, and using AI to close the gap between "curious hobbyist" and "can actually run a protocol end to end."

Who it's for

• Software engineers and tinkerers who want to get hands-on with biology
• Career switchers considering a move into biotech, pharma, or bioinformatics
• Educators and parents building a serious home science setup
• AI researchers who want physical-world intuition for what LLMs can help coordinate

What you'll build

• A safe, well-ventilated bench with pipettes, a mini centrifuge, a thermocycler, and a gel rig
• A starter reagent and consumables list sourced from hobbyist-friendly suppliers
• A repeatable "plan → run → debrief" loop where an AI assistant helps design the experiment and interpret results

Prerequisites

• A spare table or corner with access to power and a sink
• Willingness to read MSDS sheets and follow basic lab safety
• Comfort chatting through protocols with an LLM before touching anything

Tools and setup

1. Inventory what you already own (timer, scale, freezer, fridge) and fill the gaps
2. Pick one starter project (DNA extraction from strawberries is a classic)
3. Use an LLM to generate a pre-flight checklist, including safety, reagents, and expected failure modes

Modules

Module 1: Safety, space, and ethics

You will set up a dedicated biology area, write a personal safety SOP, and learn what kinds of experiments are appropriate for a home setting and which absolutely are not.

Module 2: Core equipment on a hobbyist budget

You will select pipettes, tips, tubes, a mini centrifuge, a thermocycler, and a gel electrophoresis rig, including refurbished and open-source options.

Module 3: Your first protocols with an AI lab partner

You will run DNA extraction, a basic PCR, and a gel with an LLM acting as a senior bench scientist who explains each step, flags risks, and helps interpret outcomes.

Deliverable

A working home wet lab, a written safety SOP, and a completed starter experiment documented in a lab notebook with AI-assisted analysis.

Common mistakes

• Skipping ventilation, PPE, and sharps handling because "it's just at home"
• Buying advanced equipment before mastering a single basic protocol
• Treating the LLM as authoritative instead of cross-checking against manufacturer protocols

Next steps

Move on to sequencing your own genome, basic genetic engineering, or bioinformatics — using the same AI-assisted loop you learned here.
