I'm trying to capture and image based on distance travelled - ideally at 1 metre intervals. The maximum speed would be around 15 km/hr .......
Any thoughts or pointers greatly appreciated.
....effect of taking 10k images in a day?...
".......effect of taking 10k images in a day?......" On my a480 no problems with 10k++, except for battery changes
and SD-Card changes. Just use a SD-Card Extender cable and external battery backup.
TriggerTrap is a (that is Now Open Source) Android and IOS app that might be of interest....(TT has an Optinal "DISTANCE TRAVELED SWITCH")

Triggertrap’s camera triggering infrastructure is based on 3 parts:-
1/. The Triggertrap Mobile App is pretty simple:-
It outputs a 19 khz sine-wave tone for a very specific duration.
Of course, the magic is in how often, for how long, and how fast you send the tone.
We are planning on open-sourcing our iOS and Android app in the next month (Feb 2017)— stay tuned.
2/. The Triggertrap Mobile Dongle plugs into your phone.
It takes this tone and turns it into a ("DISTANCE TRAVELLED") switch — if the tone is played, it closes the circuit.
If not, it, er, doesn’t....
3/. Finally, you need a camera connection cable running from the Mobile Dongle to the camera.
There are quite a few different ones — to find the right one, try this... [Version 1; Needs .... Design modification's .... for CHDK]
Building a Triggertrap (Ada) compatible Mobile Dongle.....
As Triggertrap is currently on its way out of business,....
"...We want to open-source the hardware we have been creating for a long time, so the design files are now available on GitHub..."
Note Triggertrap version 1 was originally Open source BUT ... the dongle was designed for DSLR based Cameras.
Also it had design flaws that made version 1 unreliable.
To make (the App) compatible with a CHDK USB Remote Release some design modification's may be needed.....(more info if there is any interest)
