Analog style GPS gauge with logging

2.3efi

Been Around the Block
This project is still in its early stages, but I do have it working on a breadboard.

I had been kicking around the idea of building an analog style gps speedometer for a while now. Sure you could mount your phone to your triple tree, but sometimes it's nice to have a dedicated piece of hardware and learn something new to boot.

The project is built with an Arduino micro controller. Some of you may be familiar with it.

When everything is finalized, I will be able to fit it all into the gauge only requiring the power wires. The nice thing about the arduino is that I can still add a lot more sensors like accelerometers, thermometers, and eventually a tach input.

I should have a lot more progress next week when my mount for the servo is done. It will retain the stock style gauge face and needle.
 
while normally I like things to just work, this sounds like it could be funny as hell
 
While I appreciate those who can build electronics from scratch, there are relatively cheap alternatives on the market now.

I have seen them for less than $150 and with a built in antenna so all you need is the 12V wire
 
Ahhhh.....to much early morning drinking for me.....
I thought you were building a 50s style GPS nav......
Like you would just keep following the needle until you got home kinda thing....

Hahaha, that would be cool!

Yeah but that's 3 times the price and none of the fun lol. Plus I will be able to log all my info to an SD card which can be cool.
 
Not a huge update, but the plate I made to mount the servo securely in the gauge is done. I need to make a new overlay for the gauge.

Here is just a short vid of the default "sweep" program driving the servo in the gauge.

That's neat! I assume you will be hiding the microprocessor somewhere else...?

I have a micro version of the arduino coming that will fit into the gauge housing.
