My background is in electronics, having experience of fault-finding in all sorts of areas, from aircraft communication and navigation systems to PCs, Laptops and all the other bits you can plug into them.
I currently have an ADC212 to play with, but intend to upgrade fairly soon, and take some courses. I know the electronics side of things pretty well, but have to learn much more about vehicle systems!
If all goes well, I may set up in business as 'Mobile Diagnostics' as there appears to be a gap in the market in my area.
