So, the Pi Zero is out, and for the first time I I am interested in Raspberry Pi enough to get one. I really like the idea of this little guy, especially the size.
The project I am thinking of is this:
1x Raspberry Pi Zero $5
1x 16x2 LCD $10
4x micro switches $5
Various lengths of wire (~ $5) (I already have lots)
1x USB to OBD2 cable <$10
And of course some programing
Combine all of these to make a DIY ScanGauge. (Around $180 for the base model) Not sure how to make the housing, but I am sure I can think of something. I am fairly certain that OBD2 also has a +12v hot wire, so maybe I can even power it that way.
What does this group think of the idea?
