Title: The mighty Alfasud at Sandown
Post by: Evan Bottcher on June 04, 2009, 02:09:45 PM
Behold the frightening fury and enormous horsepower of the boxer engine...  Um yeah.  Kinda runs out of puff at the end of the front straight, huh?

Seeing that MX-5 launch into the gravel made my day! (i've got the flu alright). I don't know why, but i found it bloody hilarious.

What's involved in getting the data logger (or whatever it's called) setup Evan? Most interesting.

Make sure you hit the youtube "HQ" button to see the full quality - for some reason without HQ it's dropping frames...

Camera is the cheapest Canon mini-DV camera I could find on fleabay.  I'm really pleased with the output actually - it has the anti-shake feature turned on (actually I don't know exactly how to turn it off!).  I think the secret to quality on youtube is the format that you upload - more on that later...

Mat - I use a Race Technology DL-1 data logger. (http://www.race-technology.com/dl1_2_27.html)  A couple of folk in the club use them.  It uses a GPS antenna and a couple of accelerometers to measure speed and cornering forces.  You can hook up lots of inputs to the unit, but I've failed so far even to get it to record RPM (electrical interference).   It records onto compactflash cards.

I then use a program called TrackVision (http://www.trackvision.net/) to overlay the data onto the video.  This program can also compress the video output as H.264 (mp4) which is probably the best quality video format to upload to youtube.

enough detail?

I also really enjoyed the Mx-5 falling off at Dandenong Rd corner - I personally think he 'ditched' after seeing the mighty Alfasud screaming down at him under brakes.  Or not.

Thanks Evan, plenty of detail. Not something i will be chasing down in the immediate future, but definitely something i'll be keeping my eyes on.

At least he managed to exit the track more gracefully than a said other MX-5 :P

Evan you are a techno-wiz.
With that telemetry it is like watching the V8 super cars. (you even drive like Leanne Tander)
