small cheap 4 channel data logger 1

[GregLocock]

Hi I'm looking for a datalogger. It needs at least 4 analog channels )(more would be better) in (say 0-10v)(more would be better) sampling at 10 Hz per channel (more would be better), with at least 8 bit accuracy (more would be better) and able to store 2 minutes of data (more would be better)

ideally it would cost zero dollars, say 300 tops. I am willing to build a kit but don't want to have to write my own assembly code.

I have found this rather good thing, but it would need a PIC based computer with a USB to store the data. A rather heavy alternative would be to just buy an old laptop and plug it into that.

This would probably do the whole job, but looks like a long learning curve.


Also, any ideas on cheap latacc and longacc and yaw rate senors?




Cheers

I watched your post with no replies. I can't help you directly.

I normally use a PC/Laptop to log the data and there are many ready built and kits that would suit you. However I assume that you want a standalone unit. There seems to be a number of these using memory cards or USB memory to log to.

Doing a stability control?

p.s I'm in Australia.

No, I'm instrumenting a kart. On a full sized car I'd just use a laptop like we do at work.

What about one of those little Asus Eee PC notebooks that run in Linux, have a solid state hard drive and are about half way between a notebook and a palm top in size. I think they are a little over $400 new.

Yes, that's a good ish solution. Frankly I was hoping for something on a single board, but there is a big advantage in having a whole computer to do it on - it is all self contained.

I particularly like the solid state hard drives for such a harsh environment.

You need to look at the hobby robotics suppliers.

has a lot of accelerometer / gyro / IMU options.

Also, this might do all the logging you need:

How about something like this;

I just got one of those Asus EEE Pc's that Patprimmer was talking about.

Picked it up used for 200$. Runs great if you strip off the original linux distro that it comes with (not a fan). I installed Xubuntu.

If you decide to go with a computer I highly recommend using this if you are comfortable with linux.
