Bike computer

Readers of this blog will know that I am slowly converting a cheap Halfords bike computer for use with my electric longboard.  The bike computer I bought  functions when it is docked in its cradle. Unfortunately when placed on top of the long board it sticks out more than 20mm from the longboard top surface. There is therefore a high risk that it gets knocked off when I am carrying the longboard on the train or I may even kick it off accidentally  when jumping off the skateboard.

Previously I had taken apart the bike computer with a view to see if I could reduce the height by removing the bottom half of the bike computer. I also wanted to do away with the docking rail. Well, by removing the bottom half its possible to reduce the total height to just 10mm. The plan is to make a recess in the skateboard to house the bike computer. However, I do have to put the battery somewhere else now. This will be accomplished by putting the battery and internal reset button in a separate box under the long board and connecting wires from the box to the PCB. The image below shows the disassembled bike computer. I have drawn a red circle around the bike computer part I will use.Other than the battery everything else in the image will be discarded.
