Hi Alan,
The problem with self build has been one of support
We found we were spending much more time supporting users who were trying to source their own components, than those who had purchased a full build
It was a case of wrong WiFi adapters, GPS, USB cables etc ...
This would identify itself as 'it doesn't work' - then a lot of time is spent trying to diagnose the underlying issue.
The other issue was that we tend to have to buy all parts in volume in order to keep the costs down, then we end up with odd bits, so for instance we buy 200 RPi, 200 GPS, manufacture 200 Bridge, if we then sell 1 bridge standalone, then we have all the other bits left over and we cannot make a complete unit - it just makes logistics so difficult to manage
Can I ask what attracts you to build your own rather than buy a complete unit ?
Thx
Lee
