Izvleček
Sodobni kolesarski šport postaja čista znanost. Za zagotavljanje minimalne prednosti pred tekmeci so bistveni aerodinamika, telemetrija in denar. V članku je opisan srednješolski projekt izdelave merilnika moči pedaliranja kolesarja. Merilnik je zasnovan na osnovi uporovnih lističev v platformi na pedalih ter z uporabo mikrokrmilnikov Arduino. Opisani sta izdelava merilnikov sile in kadence pedaliranja ter izdelava prikazovalnika treh fizikalnih količin: sile, frekvence in moči. V zaključku so podane možnosti nadgradnje in izboljšav izdelka.
Abstract
Cycling Power Meter
Modern cycling is evolving into the science of aerodynamics, telemetry, and money to achieve marginal gains. The article explains a student project to build a functional strain gauge-based cycling power meter with a cadence sensor and a handlebar-mounted display. Different Arduino microcontrollers were used to control force and frequency measurement, wireless connection, and an LCD. The conclusion provides some ideas regarding the improvement and upgrade of the device.
