55 teams will contest this year’s men’s and women’s races, up 5 from last year.  That’s what we like to see.  Mission #3 of the buggy alumni association coming up spades.  Even though we’re up 5 teams, there will be only 19 heats which is 6 fewer than last year.  The trick is that since hill 1 was repaved this summer, buggy can once again use all three lanes and set up some action-packed heats.

Now that the heats are settled and it is 9am Friday morning, the auction is open for bids!  Head right on over to

and get in on the action.  Remember …

• the first $1,000 we raise goes straight to the jumbotrons.  If we can’t contribute our piece, they won’t be back next year
• every auction-winning bid gets doubled thanks to a super amazing pledge from an anonymous buggy lover.  Help us make the most of this opportunity and max out the $2,000 they have pledged.

and the heats are:

Update: There were  few last minute changes to the heats which are now marked in orange …

• Phikap will not be entering a Men’s C
• CIA C moved from lane 2 to lane 3 in Men’s heat 2
• CIA A moved from heat 7 to heat 6

We had to wake up way earlier than alumni normally do for rolls, but it was worth it. The timing system (original post, post 2) works like a charm and we’ve got a good handle on the software now. Click on this picture of Fringe’s new (unamed) buggy crossing the line to see a sample of finish line shots. This system is going to be more accurate and reliable than the old one, but the pictures of the finishes are definitely the most entertaining part.

The background is still low-contrast and varied because the finish line currently looks like it was drawn with sidewalk chalk by a drunk toddler. Once we get a nice thick bright white finish line, these images will be really nice. It will also be later in the day and thus lighter than when most of these were taken. The quality was already getting better in the second half of our day today. These are all aesthetic concerns though, even the lowest quality images we’ve gotten so far were sufficient to quickly and precisely determine the finishing time.

Some things you might notice Continue reading →

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.

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.
