Low Power Outdoor Electronic Signs
Hi,
Hey, I have a project that requires an outdoor sign like those radar signs that show you how fast you're going. So, it will have to be solar powered and the power budget will be TIGHT. Unlike the radar signs, my sign needs to be on all of the time, so I am thinking LEDs are out. I am doubting LCDs would be able to handle the temperature extremes. Might those magnetic "chicklet" signs work? - Who sells these, anyway? (Googling hasn't been kind to me about this...) Any other ideas about what low power approach would be good? Thanks, Dan |
