DIY: Speedomerer--> Does exit an enclosure for the DFRobot LCD SHIELD?

I would share with you a project that I've developed recently, this is a speedometer based on Fritzing and Arduino and a LCD Shield of DFRobot.
What I’ve done in this project:
- Design of a speed sensor wich consists of: Reed Switch+Resistor+Plug, using Fritzing.
- Arduino Code- I will share it in my blog-.
- Components selection and mount: Power source, mounting jack connectors, cables, etc.
Compounds of the project:
- 9V Battery + Jack connector.
- Arduino R2.
- LCD Shield from DFRobot.
- Speed sensor –designed with Fritzing-.
- Others: Cables, connectors, etc.
At this weekend I’ve already mounted on the bycicle the speed sensor and I’ve performed the early tests of the prototype. Here I put you the conclusions I’ve arrived:
Conclusions after the first test:
- Improper contrast of the LCD screen. In the day light I can’t see the characters of the screen.
- I need a box where I can put the electronics.
- The speed calculated by the microprocessor is too high. I guess that, modifying the code I will solve the problem – I will share my experience when I do it-.
- The speed sensor works properly. However, I would improve the design, some comments:
o The connection between the 3 cables –VCC / GND /Signal- I’ve done is soldering
o 1 cable (with 3 wires), better than 3 cables.
o The circuit is outdoors. How could cover it in order to do it more resistant?
Therefore, here I put my questions for you:
- As the LCD can’t show the data properly in the day light. ¿What options do I have in the market – other technologies I mean-?
- Does exist any enclosure for the DFRobot LCD shield? - I want to show only the buttons and the LCD and in this enclosure has to be also the batteries.
- What options do I have in order to improve the speed sensor design, because it must be more resistant and easier to mount it.
- What cable -3 in 1- would suit to this application?
Finally, I attach you the link where I have posted photos and comments of the project:

Thanks in advance,
Anton

2012-12-05 03:34:24 Wow, it looks cool. I'd like to hack my bicycle and extend a solar power supply system based on your project!
1. For what I know, you could try the VFD screen.The effect and the brightness of the VFD screen are really good.
2. We will consider about this series product.
I think we would try to manufacture some samples with the 3D printer later! Thanks for your suggestion!
3. I think the sensor just need an enclosure for mounting on the bicycle.
4. The servo extension cable may be a good solution. Please take a look at the link below. But the length of this sensor is not enough.
