Minimal Hardware Design Solutions

The “Minimal Hardware” design solution is a simple yet very practical design that provides the features needed to conduct a successful race event. This design keeps it simple by using race management software running on your PC to control the race timer and display race results. Since it does not use numeric displays the hardware is kept to a minimum, greatly simplifying the build process and keeping costs down. The download packet has everything you need for your project including a schematic diagram, parts list, design notes, the Arduino software source code and software installation instructions.
This “Minimal Hardware” design is available as a free download and comes configured to operate with one of four race management software packages as follows:
  • Option 1: Authors' race management software (See images below) - Is supplied free with the download and provides for timer control and display of racer names & car numbers and race results. Racer info is loaded from a user created roster and race results can be viewed/printed at race completion. New enhanced version just released 6/11/2021.
  • Option 2: GrandPrix Race Manager by Lisano Enterprises (http://grandprix-software-central.com) - Must be purchased by the end user. This is the most popular and widely used race manager by Scouting & AWANA groups. Has all the features needed to prepare for and conduct your race event.
  • Option 3: DerbyNet Race Manager by Jeff Piazza (http://jeffpiazza.github.io/derbynet/) (Free download) - Network based allowing multiple platforms to log in and access race rosters, race results, standings and more.
  • Option 4: Pinewood Master™ Race Management Software by Marc Speth for Apple MAC (http://www.pinewoodmaster.com/index.html).

- - - Author's Race Management Software - - -
A new enhanced PC based version of the author's race management software is now available as part of the free download. Features of the enhanced version include:
  • Race events that are run from a Race Plan (schedule) providing car lane assignments for each heat.
  • Automatic generation of the race plan from a user provided roster. Race plans use the Partial Perfect-N (PPN) scheduling method. These types of plans are the most commonly used by scouting and AWANA organizations and satisfy the conditions where (1) each car races the same number of times, (2) each car races in each lane and (3) where possible (depending on the number of racers in the group), each car races against different opponents in each heat.
  • Display of car number and racer name assigned to each lane.
  • Lane masking – both manual & automatic (aka: “BYE” lane).
  • Ability to skip or rerun a heat.
  • Ability to view results from previously run heats.
  • Generation of the following reports for viewing/printing:
    • Race Plan – Print out is typically used to assist in staging cars for the race.
    • Race results report – Provides lane times of each car for each heat ran.
    • Standings report – Available at the completion of the race. Provides race standings (1’st, 2’nd, 3’d, etc.), average time and fastest time for each racer.
