Timing system in hand and working

About a month ago, we announced that Sweepstakes and the Buggy Alumni Association had teamed up to select and fund a new and improved timing system for buggy.  We are renting the system for an extended period this year so that we have time to thoroughly test it in the buggy context and make sure that it is better than the old system.

The system arrived over spring break, and yesterday evening, we learned how to assemble the hardware and operate the software.  The results were an excellent start. Both the hardware and software have a definite learning curve, but in a couple of hours we had the whole system unpacked, set up, and recording timed photo-finishes. The picture at right shows my dog Ruby edging BAA president Carsen Kline at the finish by 0.28 seconds after a 43 second race around the back yard. The quality of the images will improve in our real implementation as we learn which lens is most appropriate, and do things when it’s not getting dark out.

We are planning on doing our next test (this time with real buggy finishes) at freerolls on the weekend of March 27th and 28th. Thanks so much to everyone who has contributed financially to the Buggy Alumni Association in our first 18 months. Being able to materially improve the buggy experience for both current students and alumni is really exciting.

Raceday timing system upgrade

One of the BAA’s biggest goals this year was to use our human and financial resources to improve on the timing system we use in buggy.  After all the work that teams put into buggy, there is nothing more important than accurately and reliably recording their time (ok, safety is always more important … blah blah blah).  We’re running a race against the clock here, we’ve gotta be able to trust the clock.

Last year, the company sweepstakes has paid to do the timing for 20 years showed up to raceday short on staff so the BAA helped out and filled in.  What we got was a close look at the system in use and a big list of things we’d like to see improved.

What we are improving on

Technology weaknesses

  • Starter gun failures : as we’ve all witnessed, the starter gun has a failure rate of 2 -5 times per year.  This results in confusion and inequitable starting conditions for the teams that are affected.
  • Starter gun – timer synchronization : the current system relies on someone pressing “start” on a timer box when the gun goes off.  This introduces unnecessary human error on one end of the timed period.
  • Finish signal failures : the system buggy has relied on for the past 10+ years uses an RF transponder in each buggy and a wire loop (in a mat on the road) that detects those transponders when they pass by.   If a buggy crosses the line and no signal is detected, there is no recourse other than using the manual stopwatch backup times.  Some buggies are more prone to missed signals than others depending on material choice and thickness and transponder location.  Nobody deserves to have their time missed.
  • Transponders are inconvenient : Sweepstakes has to orchestrate the distribution to every team.  Teams have to find a place to secure it that doesn’t interfere with the driver or the steering.  Raceday is no time to add parts to a buggy.
  • Inaccuracy of the crowd-facing clock : the big black and yellow clock is manually matched to the official time as it is running, usually a minute or so into each heat.  This means that the time people see when the buggy crosses the line is highly unofficial, and has been off by large margins in the past.
  • Delay in reporting official times : because it is somewhat time consuming to recall official times from the current system, the times posted on the leader board are usually the backup manual stopwatch times.  In very close races, this could result in a reversal of rankings once the official times are known.

Personnel weaknesses

  • Rotating staff : because the company previously contracted often has other races on the same weekend, the same timers are not always available for prelims and finals.  This discontinuity introduces opportunities for error when it matters most, on finals.
  • False start enforcement : outside timing professionals have not in our experience been sufficiently knowledgeable about the rules and procedures of a buggy race start.  Because none of the sweepstakes committee is in the immediate vicinity of the start line, the starter must be able to manage false start and restart situations in accordance with the rules.

Rolls Statistics Fall ’09

With another semester in the history books, it’s time for the BAA to play historian/statistician and make note of a few numbers that sum up the semester.   As with the last edition of rolls statistics, the idea is just to document things and to give the orgs and sweepstakes some feedback on how things are going.

Fall 2009 (with the previous 2 semesters for comparison) looked like this Continue reading

Driver tank tops available from Sweepstakes

Sweepstakes is making and selling a run of driver-specific tank tops, and they were nice enough to ask if any alumni or other cmubuggy.org readers would like one while the order is going in.

Click on the thumbnail to take a look at the full design.

  • On pre-order now for $11
  • expected to arrive in 2 weeks
  • specify size: women’s S or women’s M
  • can be picked up at rolls or mailed to you
  • email sweepstakes chair, Jess Thurston to order –> jessicathurston532@gmail.com

Protest now! G20 forces sweepstakes to cancel rolls!

Actually, it would probably be a great weekend to roll. When else are we going to have the Secret Service and the US Army helping us keep cars off the course? From what we’ve seen so far, they sure as hell know how to get the job done. There are ten foot high steel crowd barriers lining almost the entire course, and jersey barriers ready and positioned to close off the gaps.

Just a reminder to those not on the sweepstakes list not to show up to rolls this weekend expecting buggies or a warm welcome.  It might also make for a bit of a slow news section until things get going again, but we’ll try to find something to entertain you.

Rolls efficiency statistics 2009

As we start a new year of rolls with a new sweepstakes committee, I realized that we computed some stats on the number of rolls in the fall of last year, but forgot to follow up on that in the spring.  The idea with these stats is just to give sweepstakes and the orgs some feedback on how well their partnership is doing at getting buggies around the course.

So here is the summary for the 2009 buggy season: Continue reading

Orgs come, orgs go

Most years in buggy see the birth, rebirth, or death of an organization but the transition from 2009 to 2010 is looking busier than usual.  We hate to see anyone go, but it looks like the net migration might come out even or positive this year, so hopefully we can stay right around 50 teams on raceday.  The more the merrier.  Here’s the breakdown …

Welcome back to buggy

The off-season is officially behind us, and the 2010 season of buggy is here.  The first day of rolls (weather willing) will be this Saturday, September 19th.  Does that sound early?  It is.  Things are getting started a full 3 weeks earlier than last year making a strong case in favor of the new policy of electing the sweepstakes committee in May instead of September.

The first roll is scheduled for 6:50am on Saturday (9/19).  Don’t miss Saturday, because there will be no rolls on Sunday due to the shortage of cops while they do their G20 warmups.  There is a decent chance that the G20 will affect next weekend as well, but I haven’t heard anything definitive on that.

If you can’t make it out, don’t forget to check back on the site for pictures and a rolls report.  Are you on a new team that isn’t rolling yet, or haven’t even joined a team yet and want a narrated explanation of rolls?  Find us around the course (check the chute first) wearing shirts with the Buggy Alumni Association logo on it.  We’ll be happy to answer questions.

The forecast for Saturday at 7am is sunny and 54 degrees, that’s a nice way to start the year.  Good luck to everyone in the 2010 buggy season.

Sweepstakes Committee 2010 elected

These kids aren’t just breaking course records like they’re nothing special, they’re also thinking one step ahead about running the show next year.  Traditionally, the first sweepstakes meeting of the year is called by the defending champion some time in September.  After a couple of meetings a committe is elected and they rush to figure out what they’re doing to get rolls started as soon as they can.

This year, they decided to do the electing now so that the committee has the entire off-season to get a feel for things and set their agenda.  It makes an 8 month job into a 12 month job, but at the wages they’re getting paid, sweepstakes can afford it.

Without further ado, the raceday 2010 sweepstakes committe is:

  • Chair: Jess Thurston (Fringe, graduating, starting Masters)
  • Assistant: Chris Shellhamer (Pika, will be sophomore ChemE)
  • Safety: JB Feldman (AEPi, will be senior CS)

Good luck to them, and good work outgoing committee.  Thanks to Vincent for hooking me up with the official info.
