battery operated can be done, robot batteries also, but i always used a 120v-12v transformer that could control power changes.

any type of font is possible, i use auto cad for most of it, so that is why it looks so good when it is done.

all pictures that i had of other signs where deleted when my system got trashed thanks to ubuntu linux. i only had those others because they where on fb.

as for the resistor stuff, it works fine and would cost way too much with that many of them. i have had these signs running for half a year continuous and nothing went wrong or shorted out. it might be beacuse of the choice of transformer i used. so unless something cateoustrophic happens, i'm not worried about the current flow. another reason they couldn't have a problem is because i undervoltage them. i use 12v but the outcome is 12.6, so if there was a problem with current then the extra LED or 2 would level it out.
