DESCRIPTION:Industrial Control Systems and Operational Technology security 
 is a growing field\, but the barrier to entry remains prohibitively high. 
 Commercial PLCs cost hundreds of pounds\, training courses run into thousa
 nds\, and purpose-built lab equipment can rival the price of a small car. 
 This leaves aspiring OT security researchers stuck reading theory without 
 hands-on practice.\n\nThis talk charts a practical journey from zero to a 
 functional OT security lab without breaking the bank.\nWe begin with purel
 y software-based approaches using OpenPLC and PyModbus to simulate industr
 ial environments on hardware you already own. From there\, we graduate to 
 Arduino and microcontroller-based solutions\, which run real PLC logic on 
 inexpensive development boards. We then enhance these setups with LEDs\, s
 witches\, and physical I/O to visualize ladder logic execution in real-tim
 e\, making abstract concepts tangible.\n\nTo bring industrial processes to
  life\, we explore 3D-printed models of substations\, pumpjacks\, and conv
 eyor systems that respond to PLC outputs\, creating compelling demonstrati
 ons without the need for large industrial budgets. \n\nWe also navigate th
 e second-hand market for genuine PLCs and HMIs\, discussing the licensing 
 pitfalls\, firmware challenges\, and security considerations that await ba
 rgain hunters.\n\nFinally\, we announce the open-source release of the Mod
 Pwn Challenge Board a Raspberry Pi Pico-based Modbus challenge board - a c
 omplete attack and visualisation platform buildable for under £15\, enabl
 ing anyone to practice Modbus protocol attacks and visualise the inputs an
 d output. \n\nAttendees will leave with practical blueprints\, parts lists
 \, and open-source tools to build their own OT security labs immediately.
