Ring Lap Timer

Ring Lap Timer Splash Screen

Time your Bridge-to-Gantry laps on the Nürburgring Nordschleife using your mobile phone!

Features

The Ervacon Ring Lap Timer is a stopwatch application specifically designed for Bridge-to-Gantry lap timing. It has several features to help you accurately and safely time your laps:

  • A loud beep confirms that you started or ended lap timing, avoiding the need to look at the display so you can keep your eyes on the road!
  • You can only start or end a lap each 5 seconds. This eliminates the risk of accidentally double clicking, for instance because the car is jerking around.
  • Ending timing for one lap does not automatically start the next lap, accommodating for the Gantry-to-Bridge area you need to cross before you can start your next lap.
  • The lap timer automatically keeps track of all your laps: when they happened, how long they took and how fast you were going. Your fastest lap is also tracked.
  • It's free!
  • It runs on most normal mobile phones, no need for an expensive smartphone.

Installing

The Ervacon Ring Lap Timer is a Java ME MIDlet application that can be used on any mobile phone that supports CLDC 1.1 and MIDP 2.0. To find out whether or not your phone supports these CLDC and MIDP versions, simply google for "<your phone type> CLDC MIDP version". For instance, a google for "Nokia 6300 CLDC MIDP version" tells you that the Nokia 6300 supports CLDC 1.1/MIDP 2.0, so this phone can run the Ervacon Ring Lap Timer.

There are typically two ways of installing MIDlets on your phone:

  1. Over the air

    This is the preferred way of installation. Over the air (OTA) simply means that you use your phone to directly download the lap timer from the Internet. Just point the web browser on your phone to the following URL (keep in mind that your carrier will typically charge you for the data traffic incurred by the download) and you should be up-and-running in no time:


  2. Using your PC

    Installing the Ring Lap Timer using your PC requires you to download it first. The application is distributed as a zip archive. After downloading this archive you will need to unzip it. Use whatever program is available to you to do this, e.g. WinZip if you're using a MS Windows system.

    Version Size Download link
    1.0.0 - 12/07/2011 ~170KB ring-lap-timer1.0.0.zip

    If you connect your phone to your PC using a USB cable or Bluetooth, you should be able to simply copy the ring-lap-timer.jar and ring-lap-timer.jad files (included in the distribution zip archive) to your phone and it will automatically recognize them as a MIDlet application. Note that some mobile phones come with specialized software to install third-party applications. Check your phones documentation for more details.

License and Disclaimer

The Ring Lap Timer uses a BSD license, so basically you can use it for free in any way you see fit!

It's clear Ervacon cannot be held responsible if you run into trouble while timing your laps around the Nordschleife. As always, drive within your ability and be careful: the Nordschleife is dangerous! Remember the famous mantra: Ambition > Ability = FAIL.
