SilverSprints -

A front end for the OpenSprints hardware kit. It allows for the racing of 1 to 4 bikers against each other in a goldsprints style race. The software is free to use and modify and you're encouraged to hold your own races! See LICENSE for more details.

SilverSprints is for OS X (10.7 and up) and Windows (7 and up).

Written in Cinder, an opensource C++ library for creative coding.

Using the Application


  • Requires OS X version 10.7 and up.
  • PC requires Windows 7 and up.


  1. Download the latest SilverSprints for your operating system.
  2. In the downlaoded zip file, there is an Arduino folder with software you'll need to load onto the OpenSprints hardware. Detailed instructions on how to do this can be found here:

App Settings

  1. Go to the Settings page by clicking the gear icon or pressing Command + 3.
  2. Set the roller diameter as the distance from the magnet to the center of the roller multiplied by 2.
  3. Choose the number of racers competing from 1-4.
  4. If SilverSprints detects an Arduino connected it will show a checkmark, otherwise it will display an X.


  1. Go to the Roster page by clicking the list icon or pressing Command + 2.
  2. Set all active participants' names.


  1. Click the START button to begin a race.
  2. At any time, press STOP to stop and reset the race.

Editing / Creating New Graphics

If you just want to swap graphics, simply replace the graphics in the assets folder. No need to recompile.


In the event of a crash, a log file will be created in a folder called "logs" in the SilverSprints directory. Please attach this file when asking for support along with any other relevant information.

Code Setup

  1. Clone the repo with all of its submodules with: git clone --depth 1 --recursive
  2. Build Cinder for your platform OS X - Windows. If you're having trouble building Cinder, it may be missing some of its dependencies. You may need to run git submodule update --init --recursive to make sure Cinder has all of its submodules.
  3. The structure of the repo is like so:
  - apps  
    - Arduino
    - SilverSprints
  - libs
    - Cinder
  1. Update Arduino if necessary. (See above.)
  2. Open the project file for your platform. It will be in apps/SilverSprints/xcode/SilverSprint.xcodeproj for OS X, and apps/SilverSprints/vs2015 for PC.
  3. Build SilverSprints. There are no external dependencies aside from Cinder itself.
