I got the V.I.O POV.1 I love it it's rather expensive much more then the go pro, but I saw someone with it snowboarding on their helmet...Lets just Say I'm happy I stuck with my decision, I love it quality is awesome it's tiny and it's very versatile

I saw the Go Pro Hero in issue 72 of AutoSalon... ...Think this might be the one I get... ...It seems to also be the only unit in the market that is Mac compatible...

Just a few things keeping me back... ...It says it can only have 2Gb SD cards... ...I've got a few 8Gb SD cards lying around since I changed to a Sony "happy snapper" and had to invest in new cards... ...It seems to only run off batteries... ...I'd like to see a lighter plug power version... ...No "Shock Record" with leading buffer... ...If you're out in the street and happen to be in an accident it would be great if it could start recording with a few minutes pre-recorded before the accident...

There was a duel camera setup (outside and inside the car) a few issues ago in AutoSalon that had the features that I want... ...However it isn't Mac compatible... ...So no go for me...

If the little Hero could take bigger cards and record longer with bigger cards... ...then I would get it...

I think they have a newer model which can read the larger SD cards now, something they didn't tell me when they sold me my Hero off the shelf... probably getting rid of old stock and it was more expensive than if I bought it from Lucas. Oh well.

Picture quality is 'okay' for the price, but I wasn't happy with the sound or the vibration (which I fixed by wrapping gaffa tape around it, I know this isn't hard to do, but another process all the same).

Look closely at the picture (when all is still) and you will see a heat like warp in the picture, sometimes its much worse and I think its electrical interference

Still haven't bought a mount yet... I really want to get one for PI. The clamp style is my preference to clamp onto my half cage. It's a pity there is no one locally who makes one..

Instead of making a new thread... ...I'm going to Bump this one...

I got me a Go Pro Hero Wide MotorSport kit... ...I ordered it from the U.S. and it arrived yesterday... ...It will be coming out on the next cruise for sure...

I use a VIO POV helmet camera which came with a mount which holds the tiny camera on with really strong magnets. Quality is ok. Here is a pic of it on my roof.

    • Yeah, that's fine**. But the numbers you came up with are just wrong. Try it for yourself. Put in any voltage from the possible range and see what result you get. You get nonsense. ** When I say "fine", I mean, it's still shit. The very simple linear formula (slope & intercept) is shit for a sensor with a non-linear response. This is the curve, from your data above. Look at the CURVE! It's only really linear between about 30 and 90 °C. And if you used only that range to define a curve, it would be great. But you would go more and more wrong as you went to higher temps. And that is why the slope & intercept found when you use 50 and 150 as the end points is so bad halfway between those points. The real curve is a long way below the linear curve which just zips straight between the end points, like this one. You could probably use the same slope and a lower intercept, to move that straight line down, and spread the error out. But you would 5-10°C off in a lot of places. You'd need to say what temperature range you really wanted to be most right - say, 100 to 130, and plop the line closest to teh real curve in that region, which would make it quite wrong down at the lower temperatures. Let me just say that HPTuners are not being realistic in only allowing for a simple linear curve. 
    • I feel I should re-iterate. The above picture is the only option available in the software and the blurb from HP Tuners I quoted earlier is the only way to add data to it and that's the description they offer as to how to figure it out. The only fields available is the blank box after (Input/ ) and the box right before = Output. Those are the only numbers that can be entered.
    • No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.
    • God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.
    • Nah, that is hella wrong. If I do a simple linear between 150°C (0.407v) and 50°C (2.98v) I get the formula Temperature = -38.8651*voltage + 165.8181 It is perfectly correct at 50 and 150, but it is as much as 20° out in the region of 110°C, because the actual data is significantly non-linear there. It is no more than 4° out down at the lowest temperatures, but is is seriously shit almost everywhere. I cannot believe that the instruction is to do a 2 point linear fit. I would say the method I used previously would have to be better.
