Re: 15 to 16 Mb per lap
The data collected is optimised to what they can realistically be analyised within a lap before the next load of complete lap guff downloads. 13 years ago there was one analysis bod examining each car in limited detail and looking for obvious 'oh crap that widgets gonna break' details. When this happens other 'spare' analysts would step in and examine the data more closely whilst the original analyst moved into the next laps data.
Some of the sensors would be as dull as what gear is selected or gear box temps which don't need 'that' much sampling or generate that much data but things like revs or driver excuse preparation would.
As there is now a whopping amount of post race analysis I would imagine that the granularity of what is actually downloaded from the car at the end of the race is much larger than 15mb a lap that is gathered via telemetry.
The telemetry was radio woowoo that I never got to grips with.
That being said I never really liked the racing, the magic at the factory on the other hand I really do miss.
Re: 15 to 16 Mb per lap
That's probably correct, remember this is usually character or binary based data from the 300 odd sensors, each sensor will have different sampling rates depending on what they are.
Also, each team has(*) to organise it's own telemetry collection (they don't have Bernies eye in the skys that capture the TV footage from the cars as they are racing). Some circuits could get complete coverage for a subset of the data as the cars were whiping around the circuit with a main data dump as the car pass near the paddocks. But at others, like Monza, the trees got in the way.
*This is based on me working at a F1 team about 13 years ago, so I hope some things have changed.
I've used it a couple of times, but not for ages. It was all rather painless but it just gives me a dirty feeling using it, it's obvioulsy a loss leader for the merchants and seems to be just another way of grabbing customer data.
I got my first bit of junkmail this monring to an e-mail address registered only with Groupon so the app has just got binned and unsubscribed from the emails that I didnt read any more anyway.
Re: I went down the DIY route
Me too, but running ESXi with a SME server install and couple of other linuxy server to play with and the cpu utilisation is negligable. Infact I was so impressed for what turned out to be a £130 server that I got another one.
Re: Looks nice
That's what I did, sort off.
I got some fag packet sized D-class amps (Sure electronics, 15w) from fleabay for 35 quid and my old Tannoy 607 and 603 speakers and some Linn ceiling speakers for the bathroom. These and some airports, either N's or G's (turned the wireless off on the G's) and Bobs your aunty.
They sound great to me and plenty loud enough which is probably all that most people would want/need. Indeed, when I needed some more amps I had to order another 6 for other people.
Not as cool as the ones in article but massive geek satisfaction value.
