Some of you have seen my LED scrolling nametag. This item is perfect for those conducting star-parties or operating telescopes at SPOC on public nights. It allows people to see your name (or any other message you program into it) after dark, when your embroidered name on your vest is invisible. (No more "hey, Miss astronomer" or "hey, telescope dude") It's now on sale at American Science and Surplus. www.sciplus.com *Item number 36714 LED Name Tag regularly $19.75 on-sale $15.00 ea.
