Rallylog (post) Update #1 – Adding a wrist strap to the SparkFun Case

As I mentioned in my last post that just before I lost my mojo I ended up completing my build of 10 Rallylogs and testing at a live event.

As these were handheld devices I decided to add a wrist strap to stop things from getting dropped and damaged at the checkpoints, especially as it can get busy as the bikes pass through a checkpoint.

Putting the Project into an Enclosure; Part 2 Machining the Case

In my previous post I described the design process I went through in selecting the right components from my Rallylog that would fit into the Sparkfun Project Case, all while mounted on a PCB. What follows is the process of getting the actual case machined with my Zenbot CNC machine. Continue reading “Putting the Project into an Enclosure; Part 2 Machining the Case”
