Decided i like the look of the zada-tech gauges but i reckoned i could build it myself a bit cheaper with more functionality. So i brought some stuff anf had a go
Just need a manifold absolute pressure gauge now and im in business
Cost so far is
arduino £24 (Should have been £60 for the actual board but i reserves some stuff online from maplins and the guy put the top of the range arduino mega adk in the bag instead of the basic uno)
Display £16
map sensor should be about £8 - I'm using a 10k pot to simulate the voltage return
the rest of the bits i had in my electronics box
zada tech gauge is £95
Great fun so far and its helped me learn some programming stuff
