Learn · Build · Automate
Engineering content built like a control panel:
tested, labeled, working.
Practical tutorials in PLC programming, industrial automation, mechatronics, and embedded systems — written by an engineer who builds the systems before he writes about them.
Four disciplines, one workflow.
Every tutorial sits inside a category built around how automation systems actually get designed and commissioned. Click a card to browse that category.
Mechatronics & Robotics
Sensors, actuators, and motion control for real mechanical systems.

Bridging engineering theory and the factory floor.
Bob Teaches Tech is built and written by Bob Odhiambo, a mechatronics and automation specialist with hands-on experience programming and commissioning PLCs across multiple platforms, along with industrial communication protocols and variable frequency drives.
Every tutorial here is tested against real hardware before it's published — not adapted from a datasheet. Bob also contributes technical writing to EEPower and Control.com.
