G-force logger project

[lond]

Hi!

 

I have constructed a g-force logger on my spare time.

 

http://gforce.servehttp.com

 

Contact me for any questions how to build it your self

WOw...very technical and confusing. It looks super-coolio though! Did you build it from scratch?

[lond]

Yepp!

Great stuff Marcus! If you ever feel like building one for TPR, please let me know. We'd love to help add to your logger data!

^ Hey Elissa, see youv'e had a sex change! And changed your name.

 

Looks really technical. I don't understand what it does though. Am i missing something?

[lond]

It can logg the g-force that you feel when you for example ride a roller-coaster and then you can do some graph of the log

Or you can put the g-force data in the bottom of your on-ride film

I have almost finish the work of G-force logger v2.0.

[lond]

Very well done.

I'm sure we all would like to see some results from the logger.

 

You should consider selling some of these

If you download the software on the page "AccmetView" and the file named "Heide Park" you can see some examples of what the logger can do. I have a few more parks from my summer vacation in Germany, Holland, Denmark and from Liseberg.

Photos of v3.3 is uploaded. It is more compact then v2.0. The new one only have a internal sensor and a one row "glow in the dark" display.

We should build one for TPR and send it to people who have a local park (or one they usually go to). The person could take it on the coasters to log the G's and sign the thing, then pass it off to another person!

Update:

 

Currently I'm working on my new logger.

It's almost finished, some hardware and software to be fixed

I used an accelerometer combined with a calculator and proccercor to log some coasters, too bad we had only 1 meter and we had to ride a coaster 3 times to get an accurate vert/lat/accel graph

[ginzo]

Thanks for the data Marcus. It was fun to read through it.

[lond]

The sensor i use have all 3 axis in one chip, so all 3 axis are aligned.

Go and look on it @ Instructables.com - Accelerometer logger with SD-card

 

Maybe build one your self

Those are pretty neat! Never knew what they looked like... I thought that they would be BIG and BULKY! Cool Stuff!
