Hi all.
Here's a guy asking about a product he might
build and market. If you have any opinions,
please let him know, or post here and I'll
direct him here too.
thanks
Joe

I think after you price out the hardware specs, intergrated features, software, and the cost of similar products on the market, you will have the answer you're looking for.

What am I willing to pay for a product that I have no specs on? $0.

hmm. sorry. forgot the specs:

I am in the middle of deciding the price point for the Video + Data Logger (VDL) that I am creating. Basically this unit will record telemetry such as speed, G force, RPM, and Lap Times based on GPS tracking. This unit will also simultaneously record and overlay video via a video camera that will be included with the base unit; perfect for immediate viewing in between track sessions.

Base Unit includes:
1. VDL unit
2. 1x Camera
3. SD card
4. Cigarette lighter power adapter.

This unit is universal for all types of cars. Most track guys will love this unit and I believe enthusiasts like yourself may be interested as well for other applications.

The most important spec is your sample rate. Top end systems on the market are around 10Hz and cheaper stuff is 5Hz and under. From my experience 5Hz is the minimum for autocrossing and 10Hz+ would be ideal.

This is a comparison of 1Hz (red) and 5Hz (blue) sample rates.

Also, video overlay, although a nice feature, isn't as useful to me as overlaying graphs and maps. It's far easier to analyze data through graphs than video. For example, MaxQData has some really good software for on the fly reviewing.

I'm not too sure how worthwhile a datalogger is for autox. I think the biggest problem is you get 3 runs and then you never see the course ever again. I doubt you really have enough time in between runs to really analyze what you've done before you have to run again and to boot, you don't really know where the course is. The datalogger just spits out a curvy line and you have no idea where the cones are. I used a datalogger before and it was neat to play with but I didn't help me with my driving or car setup.

The video logging sounds better just because you can see what's going on and more importantly you can review it before your next run. But anyone can just buy a camera and mount it on their headrest.

Maybe if you combine both, you'll get more info but the problem I see is that you won't be able to process the data between runs. You can do it after the event but then you'll never see the course again.

Sorry Mark, I have to totally disagree... recently comparing my runs using the MaxQ with a VERY fast driver in my car has been one of the biggest eye openers to improve my driving. Realizing that "wow he's doing X in a particular spot, while I'm doing Y" really made my times drop... even though the analysis (over-analysis? Smile ) took place after the 3 runs.

Data logging is also very useful for those runs where you could swear that you were slower, but the clock tells you otherwise... then you can pin point what you did where to make up the time.

All this, overlayed with video would probably have me spending 20-30 hours per run over analyzing each and every second of footage... which is really fun anyhow! Smile

hmmm. yea i think that video overlap with data is pretty cool and be useful for autoX but not as useful as it will be for Track people since someone has already pointed out that you'll never see the same "track" again if ur in AutoX. but i think it'll be good to compare with ur friends and see what they did and so forth.

Keep the discussion going on guys. this is great

This is exactly the kind of package I was looking for; but, I'd have to know a lot more about specs before I'd consider.
