I have a bunch of flip panels from buses so a clock is in my future. They are LOUD inside a quiet house. What I'm thinking is 6 digit but with a motion sensor that only activates the seconds when someone is near. Otherwise the seconds are blanked out and the HH:MM is shifted to the center of the display. In the bus display, each row is treated as a shift register while the columns are treated as bits in a word, A friend to whom I gave a panel has figured out the driving scheme. Even if GPS or WWVB wasn't strictly necessary, I'd have to have it just to handle the switch to and from DST. I finally got all the clocks in my house changed out to WWVB clocks so now DST day is just another day. > > I don't trust Aliexpress, too many of the sellers are shady and there is no > real buyer protection. If the seller accepts PayPal then maybe you have a > shot. Otherwise you are just broadcasting your credit card all over China. We've had very good luck with both express and Alibaba. A few rules. Never ever use a credit card. Always paypal. I loathe paypal but I have an account just for them and dxexpress.com. ALWAYS buy or negotiate samples before buying for effect. Many of those manufacturers have no idea what they're making. They just cloned something that looked cool. IF you're buying for effect from an Alibaba vendor, ALWAYS use an escrow service. Hard lesson learned here. They always want the full amount paid up front. The most we'll do is pay for the raw materials. The rest goes in escrow. If you're having something manufactured, specify every single dimension, detail and step. The last round of extrusions we had made, we forgot to specify deburring the drilled holes. Just guess what we got! In the escrow agreement, specify that they must ship several (usually 5) pieces from the finished production for our inspection before we release the money. Of course, they can "cook the book" on the samples but that's better than being blind-sided. After the extrusion debacle (the samples WERE deburred), we've started requiring a video of them picking samples at random. Yeah, they're a pain in the tutu but the cost saving is worth it.
