Bluetooth Channel Sounding is not just a phone feature. For STEM labs, sports timing gates, and accessibility tags, it introduces a better conversation about distance, error, and calibration.
Bluetooth Channel Sounding Could Make Sports Timing and Accessibility Tags More Useful Read More
A practical engineering-led guide for planning an e-bike charging zone in a maker garage without turning it into a random extension-cord problem.
E-Bike Charging Zones Belong in the Maker Garage Plan Read More
A slick capacitive touch pad can be the wrong input for an accessible STEM build if feedback, mounting, moisture, or calibration are ignored.
Mechanical Switches or Capacitive Touch? Accessible STEM Builds Need the Right Input, Not the Slickest One Read More
Sports timing can be a strong STEM project when teams choose sensors around the measurement problem instead of copying pro timing systems.
Photogates or UWB Tags? A STEM Sports-Timing Build Starts With the Measurement Question Read More
A broadened transportation-tech guide for maker garages: where e-bike charging belongs, what to keep away from it, and how to reduce avoidable electrical and thermal risk.
E-Bike Charger Placement Is a Maker-Garage Engineering Checklist, Not a Floor-Space Problem Read More
E-bike torque and cadence sensors are more than ride-feel features. They are approachable lessons in controls, signal quality, safety, calibration, and user feedback.
