Engineering-first robotics, AI, maker hardware, STEM, and creator technology reporting
STEM Lab covers STEM education, youth robotics, classroom technology, competitions, learning tools, and engineering literacy, with attention to safety, cost, reliability, and real-world teaching constraints.
Adaptive switches are a strong STEM hardware lesson because they turn input design into a real engineering problem: mounting, debounce, safety, feedback, and user fit.
Adaptive Switch Interfaces Are a Practical STEM Hardware Lesson, Not Just an Accessibility Add-On Read More
Student robot vision failures often come from lighting, exposure, glare, target contrast and camera mounting. This checklist helps teams debug the scene before rewriting code.
Robot Vision Lighting Checklist for Student Teams: Fix the Scene Before Tuning Code Read More
Adaptive controllers are not just alternate gamepads. They are modular input systems with mounting, switch, firmware and setup tradeoffs that STEM teams can learn from.

Power over Ethernet can simplify fixed cameras, timing views and lab monitoring for student robots — if teams plan cable length, switch power budget and labels before competition week.
PoE Camera Runs Can Make Student Robot Labs Easier to Debug Read More
Raspberry Pi’s LoRa device roundup is a useful reminder: field sensors need range, duty-cycle, power and gateway planning before a maker project leaves the bench.
LoRa Sensor Projects Need a Radio Plan Before They Leave Wi-Fi Range Read More
Matter and Thread make smart-home devices easier to mix, but sensor placement still depends on mesh reach, border-router location, battery behavior and disciplined testing.
Matter and Thread Sensor Placement Is a Lab Exercise, Not Just App Setup Read More
E-bike range and motor specs are easy to compare. Battery certification, charger matching, service support and replacement paths are the engineering details that decide whether an e-bike is a responsible project or commute tool.
E-Bike Battery Certification Is the First Spec STEM Riders Should Check Read More
SunFounder PiDog V2 looks like a review-worthy Raspberry Pi quadruped for STEM labs, but TVG would want to test calibration, power, gait reliability, AI features, and classroom durability before recommending it.
