Here I show you my version of the handlebar mount for the Garmin eTrex GPS handheld unit. The only thing that you really need to buy is a worm drive hose clip from your local harware store (mine cost about Rs.10/-). The wire for the mount can be any stiff length of wire e.g a bicycle spoke.
Tools needed are a plier to bend the wire and a screw to tighten the hose clip. This can be mounted on either a bicycle or motorcycle or maybe even places like a vehicles steering wheel or even a hang glider !!
What makes this so special is it's simplicity and good looks.
Step 1: The materials
First you need a worm drive hose clip as shown in the picture below. Make sure the diameter of the clip is sufficient for the handle bar you will be mounting it on. Also remember that the wire goes between the clip and the handle bar so the diameter needs to be slightly larger.
Step 2: The materials 2
Next you need a length of stiff wire. I got mine from a calendar as shown in the picture. A 1 foot length or more of wire should be sufficient to start with. You should be able to use a cycle spoke or whatever is easier to find around the house for the wire. You might want to paint it later to prevent it from rusting.
Step 3: The tools
You will need a pair of pliers to bend the wire, if you want you can also use a nose plier (the ones with a pointed end) to make the smaller bends.
A screw driver will come in handy to tighten the hose clip and maybe even a file to smoothen out any rough edges at the ends of the wire (you don't want to scratch you eTrex).
