This instructable shows you how to easily build a water proof housing for your mobile phone.
Trying to use my mobile phone as a navigation and tracking device during a bicycle tour forced me to look for a proper dock to mount it on the handlebar of my bike. I am using a HTC desire Z. This mobile has a keyboard that can be folded underneath the display. It's an android phone where many mapping and navigation apps exist on the market.
After a long search I realized that there is no dock available that fits my needs;
1. Waterproof even during heavy rainfall
2. Securely mountable on the handlebar, stay there also during accidents
3. Easy mounting of the phone
4. Access to screen (touch display) and keyboard druing the travel
As there where not much time left until our easter tour I had to find a quick, simple and easy solution.
Step 1: Parts needed
I recommend using a good quality box like the emsa clip & close. The box can easily be open and closed with clips. The box is made of strong but flexible platics and uses a rubber ring to ensure that it is sealed tightly wen closed.
Besides the box you need some wire strap, a block of styrofoam and the following tools;
- some sharp knife, I used a scalpel
- a ruler
- a marker pen
- a hot wire styrofoam cutter
i build the hit wire styrofoam cutter myself, using a power supply a big resistor and a wire mounted on a holder. The restor is used to adjust the current that flows through the cutting wire and thus regulate the heat that the wire produces.
