Custom fitted HUD system.

[Mod F]

I am sketching up ideas for securely mounting a functional Heads Up Display atop the instrument cluster arch. No mechanical fixing just one of those really grippy dash cam/satnav holder mats as a base and then a fairly cheap 7" android tablet on top of that held at the right angle to throw reflection off inside windscreen. There are a few apps already which would run the proof of concept to try out at least, ideally though a more custom and reactive brightness and display system down the line would be good too.
Functionally it could present data like outside air temp, compass and even directional navigation aids.. though primarily a nice glowing red speed meter that lights up ahead of you when you start up would be fun too
