This project has been dormant awhile
But it's moved up the queue. I removed the GPS tracker from my folding bike because I now go back and forth between two bikes. I want the GPS tracker to be modular enough to easily attach to whichever bike I'm riding that day. What I decided to do is to embed the GPS in an aluminum Hammond enclosure, and mount it to the seat post. The enclosure will not only house the GPS tracker, but it will also serve as a mount point for the next iteration of my "Lefty Lights"
. See that small black box the hand trowel is mounted to? that's where the GPS will go
In the current setup, I have a custom made (on the MakerBot) mount that attaches the metal enclosure to the rear rack. But my second bike has no rack and won't be getting one. So, I will create a custom mount point, one for each bike, attached to the seat post. The seat post angle on each bike is different. But all I need do is have each terminate in a 90mm vertical square, and I can use quick release VESA mounts as the standard modular interface. Here's a draft of the custom mount for my A-Line:
Once done I'll have a small modular box that provides some safety (blinky lights!) and security (GPS tracking... a function non of us ever want to have to use, right?)
