Help with coding acceleration software

I have bought an Arduino UNO R3, GPS expansion board with an external antenna and memory slot, 3-axis gyroscope. I want to build a product that can accurately measure the acceleration, positive and negative G-forces and save it to the memory card, which then is possible to analyse. 0 -100km / h 70-140km / h, 100-150km / h, 100-200km / h and also log maximum top speed. Positive and negative G-force. It shall also take into account the upward/downward slope and view it in %. It should also be able to use Google Maps or similar and to show you where you drove. Compensation is paid, of course.

A product that i like is this (its very expensive though):

That product costs $600 from their store and it's cheap at the price!

I would suggest that anyone telling you they can replicate it for less than that price either (a) will work for free (b) has no idea what they are doing or (c) is lying to you.

As a general rule, replicating an off the shelf product will cost an order of magnitude more than simply buying it. Unless, of course, you place no value on your time.

I am already involved with a similar device, so I wouldn't bid on it since it would create a conflict of interest, but I wouldn't touch what you're asking for less than $10,000.

Yeah, its not worth it for playing around..i could buy the racelogic pb instead but thats not a challenge.

Also...arduino in my mind isnt ment to be "sold" in that mather. its open source software/hardware with no limitations for developing.

Then why are you offering to pay someone to do it? Learn to develop software and you can do it yourself.

I dont have time to learn from the beginning, i need a kickstart in the right direction..im also lazy :slight_smile:

im also lazy

Probably will become evident when trying to get paid.

Not if we get paid first then that will be a great motivator for them to make sure they get their goods :slight_smile:

Surely all you need to do is save the raw values to the SD card, comma-separated? The OP's spec is:

measure the acceleration, positive and negative G-forces and save it to the memory card, which then is possible to analyse.

Stuff the raw values out to the card, and it becomes "possible to analyse". Job done!

It should also be able to use Google Maps or similar and to show you where you drove.

Holy crap - that's an entirely different ball game! Are we talking connecting to the 'net from a moving vehicle and displaying a map on some sort of wired-in display?

I'm with cedarlakeinstruments on this one. Buy a commerical GPS + accelerometer product. Arduino is not a cheap way to duplicate the functionality of a thousand-dollar item. If something costs a thousand bucks, it's because the manufacturer is using economies of scale to do it cheaper than it's possible to do as a prototype.

OP, in general "I'm going to duplicate the function of some thing that's already out there on the market" is not a sound business idea.

Jupp, will most likley settle with a raw data collector and some program to pick out what im interested in and do a push button for start and stop to make "runs" and save it.

The people telling you to buy the off the shelf solution are offering you the best advice anyone can give you. Even if I bid the project at a wage rate equal to the US Federal minimum wage you would be money ahead going with the off the shelf code.

To pay for a one off solution that is close to the off the shelf solution you need to pay someone to:

  • write the code
  • pay others to test the code
  • write the users manual (a crucial item missing on many one-offs)
  • support after the purchase
  • ...

You will choose to do what you want but follow the advice given you if you are smart.
