About

Strobr Scope

This utility app uses your device's camera to measure the frequencies of various cycles, including rotational speeds and electrical light frequencies. It offers a more convenient and less distracting alternative to traditional stroboscopes, capable of measuring even very slow rotations.

Highlights
  • Camera-based stroboscope
  • Measures rotational frequencies
  • Measures electrical light frequencies
  • Measures slow rotations
  • Continuously variable frame rates
  • Convenient and less distracting
Features
Read full description

Strobr Scope is a camera-based stroboscope app that relies on continuously variable frame rates to measure the frequencies of cycles. A traditional stroboscope flashes bright lights at a specific frequency that can be easily matched to the rotational frequency of i.e. a car wheel using persistence of vision (POV), allowing the rotational speed to be measured. Strobr Scope works similarly, but can also measure many things like electrical light frequencies and very low slow rotations that a traditional stroboscope cannot. It’s also more convenient and much less distracting to others! This app was built at PennApps 2017 and won top 30 there.

Bugs and requests

nRF Connect for Mobile

Reported bugs

4 issues
  • Can't read data from Bluetooth device
  • Tries to ask for Bluetooth connection when Bluetooth is off. Asks to connect to devices when Bluetooth is off. Who knows what this app is doing in the background without permission?! What ever it is , it ain't good
  • Tapping "tabs" doesn't work (nothing changes in the UI). To get some response from tapping UI controls typically requires (a) launching nRF Connect, (b) switching to another app, (c) switching back to nRF Connect. I've tried uninstalling and re-downloading. Same result. This used to be the bee's knees of BLE tools but it's only worth 1 star at the moment (v2.7.11).
  • Cant go past the initial announcement. The app is unresponsive to the taps.
