Pi Zero Bikecomputer is a GPS and ANT+ bike computer based on Raspberry Pi Zero(W, WH, 2 W). This is the first DIY project in the world integrated with necessary hardwares and software for modern bike computer. It measures and records position(GPS), ANT+ sensor(speed/cadence/power) and I2C sensor(pressure/temperature/accelerometer, etc). It also displays these values, even maps and courses in real-time. In addition, it write out log into .fit format file.

In this project, Pi Zero Bikecomputer got basic functions needed for bike computers. Next target is to add new functions which existing products do not have!

You will enjoy both cycling and the maker movement with Pi Zero Bikecomputer!

Here is detail articles in Japanese.

• I tried to make a bikecomputer, the result was pretty good
• Let's make a bikecomputer with Raspberry Pi Zero (W, WH)

Daily update at twitter (@pi0bikecomputer), and my cycling activity at STRAVA.

• Easy to make

  • Use modules available at famous Maker stores.
  • Assemble in Raspberry Pi ecosystems.
  • Install with basic commands such as apt-get install, pip and git command.

• Customization

  • Need only modules you want to use. Pi Zero Bikecomputer detects your modules.

• Easy to develop

  • Pi Zero Bikecomputer uses same libraries as for standard Linux.
    • Python
    • numpy
    • PyQt5 and PyQtGraph
    • GPSd for GPS modules.
    • CircuitPython libraries for some I2C sensors.
  • So, you can run in cross platform environments such as Raspberry Pi OS, some Linux, macOS and Windows.

• Good balance between battery life and performance

Some functions depend on your parts.

USB dongle is required if using ANT+ sensors.

Strava heatmap.

RainViewer and openportguide are available worldwide.

In Japan, 気象庁降水ナウキャスト(rain) and SCW(wind) are available.

it displays three of the people around you in the order in which you caught sensors using ANT+ continuous scanning mode.
