Yeah some of those could be quite useful, guess you would need a soldering iron and stuff to make all of these up and some technical knowledge?

Car battery indicator is a good idea! Also like the sound of a pulsing brake light!

Could you do like a rev counter one with LED's? That possible? Would be sweet :thumbs_up:
