Well it has been busy the last few months, but I finally freed up enough time to add the design documents for the Grand Prix Timer to the build page on my Blog and add the source code to a new Codeplex project. With these items you should be able to build your own after doing a little homework.
- Project goals and part selection:
- Design Documents:
- Source code:
Note: All the design documents I have created are now uploaded. However if you have any questions please let me know and I will add details where needed.

The Netduino based Track Timer has been a fun project and last weekend we finally got to see the new 8 lane track and timer in action. 50 racers came to race their cars in an attempt to win a speed or design trophy. The timer performed great and the only real issue I had come when the person operating the start gate closed it before the race was finished. It would reset the timer and the software would not record any times (even though i send the times as each racer finishes). This resulted in us having to rerun 2 of the heats. I will look at ways to change the code so that the Grand Prix Race Manager software will still complete a race if the start gate is closed. We are hoping to bring it out again before the Grand Prix next year as we all had a blast (especially the kids) and we want to do it again. I have added a video and some pictures below
As for the project details (Bill of Materials, process diagrams, code, and build pictures), I will be working over the next week or two to get the project page updated with all the details on this project. If you have any questions or would like additional details on a portion of the build.
Thanks for the support during this build. I have some ideas for my next project but I am taking suggestions, so if you have an idea leave a comment or send me an e-mail. If I like the idea then i’ll build it.

Pictures of setup (and a shameless plug for my kids cars).
FYI – sorry about the picture quality, My SLR died and we have not fixed / replaced it yet so these were taken with my cellphone.

I received the 2 aluminum parts I ordered last week and discovered that the shipping was almost more then the parts. It was 27.46 for the parts and shipping was 24.68 for 13lbs and 2 separate shipping containers. What I didn’t realize is that if you get stock that is different lengths (6′ and 8′ as I did) then they have separate shipping containers. Wish that they had told me before hand. Oh well guess I know better for next time.
