Projects General Guidance

I'm new here, so please forgive me if the kind of help I'm asking is frown upon.

Two reasons I'm asking is that (1) while the device I would like to put together is critical to my project, my main focus is on what is done with data collected and taking actions on it and (2) the sensors etc that I seems to need seems pretty pricey and the gf is currently on a trip in a country I can get it cheap. It's just for myself while developing my system.

I got a few projects planned for the "device", so listed the requirements below. The main is a hobby project where one goes for an offroad ride and it records the entire trip, not only location but also the angle at which the bike is leaning, speed, etc (yeah yeah, I know my bike's garmin can do a lot of that itself, but I'd like to do something on my own and add stuff like detecting an accident...stuff like that)

What I'm asking is either quick help here (will truly appreciate it) or a knowledgeable individual to contact me on the side, giving advice for which I'm willing to pay for his / her time.

  • Arduino, powered by both a battery (as backup) and a power source (motorbike battery)
    If possible raise some event that the power source is not available and switching to the battery (if the backup battery could be rechargeable from the power source that would be great)

  • Able to send notifications and data to my api / web server (GPRS module?)

  • Able to determine its current location (GPS Module)

  • Able to determine the current "angle" of the device

  • Need be able to change settings when connected to a mobile phone / app (Bluetooth)

That's about it. Also willing to look at a single "device" that does all that. Again, my focus is what I'm going to do with the data.

Hope this makes sense. Everyone complains I suck at explaining myself. lol

A single shield that have GPS GSM GPRS solve half those right? I saw one that cost like $69. Good price?

Not sure important, this will probably be a huge bulky messy prototype. Like I said, needed to get the software side of things sorted (not on the device, but my server acting on notifications)

Far from sucking, it is reasonably coherent. One area that needs attention is the power supply. There can hardly be much shortage, but it might not be the cleanest, and a good 5v regulator would be desirable.

Any bluetooth terminal would be able to upload settings and download data.

Able to determine the current "angle" of the device

That is tricky if the bike is being driven, easy if it is stationary.
