No hijack if it relevant to more cost effective navigation it 'belong' here.

What are your thoughts (Garth, Addie, et al) on the Rally Blitz app on an iPhone?
I was really surprised on how well this seemed to work on the last Amageza.
The App is cheap and many people have iPhone's so that represents potentially a very cost effective approach for many people?

Personally I think that app is hitting the mark 100%.  The f2r app for Android is way down on usability and user interface.

That was my initial plan to use a Smartphone as 'hardware'. Android due to cost and availability.
Pros:  GPS, Compass, touch screen, memory, backup battery, etc, etc all rolled in one package already for less than R800.00 (the price for the GPS only)
Cons: Connection for external buttons and screen 'visibility'. Android programming (for me).  Size, mounting and power supply. Readability (I battle to read my phone on the bike's hands free mount.)

The connection to the external buttons could be overcome with a USB 'server' as the Android platform does not allow 'client' USB devices.

It is still on my list thou as I can now get a WIN8 smartphone for R800.00!!!!!  Programming will be a breeze with my current dev system. (My dev system are Android capable but I am not (yet))

Why not maybe just make a brighter screen and handle bar controls for the iPhone?

ie some sort of Buletooth repeater screen and handle bar controls?

That way you could keep your phone in your pocket where its safe from mud dust etc. 

Just a thought?

That is what the Rally Blitz guys are busy with, adding a Bluetooth device (buttons to operate the app)

Nice thread this  :thumleft:

I suggest inviting Brett cummings aka Rallyerider2 here for comments?

i'll do it

@KilRoy GREAT
Like I said, this thread is not only for development of navigation eq. it is also about the actual usage by the rider.

Sorry for my ignorance, but how does the ERTF/CAP Repeater work, do you upload the way point coordinates to the device before the race or do you have to "enter" the value when reaching a way point. I have played with that feature on the Rally Blitz app (although just riding the mtb bike) and It works great when doing an unknown route.

Arduino Pro mini 3.3V, and yes, a 3-axis tilt sensitive "compass" and some fancy software to smooth it out like that ;)

Short update.
the basic programming is done.  We can read the GPS, Magnetic compass, front wheel pickup and buttons.  Initial tests looks good.  We read the GPS once per second, the compass 5 times and the wheel sensor with an interrupt.

At this stage we are looking at two GPS distance calculation options. (the GPS does not 'know' the distance because it does not have a 'start point reference'.

Short screen clip of the readings IN THE OFFICE. no movement on the GPS.

The next 'hurdle' will be sourcing the screen.  I got a LCD but they gave me a LED driver.  The software all done.

I sort-of started working on a Raspberry PI + mpu-9150 type thing, but I'm keen to see where this goes.

@Dogyloss
the problem is the raspPI is overly 'powerfull', too big, too much overhead, does not talk to the outside world 'directly' and are too expensive if you try to build a retail product.  (That was when I did my evaluation.)

I think the best chip would be one from the Microchip PIC family, but alas I could never get them to work properly.  I am just to stupid to grasp the register setting things. (That was a few years ago, maybe things changed.) They are more common, bigger variety and run faster clock speeds than the ATMEL based Arduino system.

In my 8 to 5 job I use both PIC and Arduino but only program the Arduino myself. Hmmm.. maybe I must give the PIC a go again as I do have all the required dev kit. Maybe I could do it now :sip:

During my research I found quite a few 'advanced' CAP heading/Trip readers. We will also look at a graphics screen to show more info simultaneously, this will however be for a separate version due to screen resolution etc etc.  Did a trip this weekend and to be honest NOTHING will beat the OLD style LCD for clarity and readability.

Yep completely agreed. I chose the RPi mostly because I can code Python and have one lying around.

The plan was to more to do something similar to track telemetry, measuring speed acceleration and lean. I'm calling it "The Wheeliemeter" :)
