I just woke up and remembering what i was dreaming about and here it is
Would be possible to make Arduino plugin that is kinda like Project Board, except it's programmable and allows you to by simply drawing PCB (like program PCB Design) - you have a fully functional PCB ready to accept components.
I don't know if this was clear enough
No, not clear enough yet. Please expand your thought.
sounds like the sort of project that needs good video output and mouse / tablet input,
and some way of drawing the pcb, like 3d printing,
might be a little out side the capability of the arduino, more PC power ,
yea, you are right, i was too rash ... But here's an idea, maybe someone will figure out even better thing, i don't know, but it sounds pretty awesome to me
