Arduino doomsday countdown clock shield

Tully wrote to us about his latest project, the Arduino doomsday clock shield. The board features six 7-segment displays counting down up to the end of the Mayan calendar.

Hey Ian,
I want to show off one of my recent creations, the Doomsday Clock Arduino Shield. You can use it to countdown the final hours until the end of the Mayan Calendar, or learn how by Charlieplexing all 64 LEDs are controlled by only 9 digital pins on the Arduino.

Via the contact form.

    I’ve been watching Samurai Circuits for a while now – but the whole thing is perplexing. Where are they based, where do they ship from? There is a big black hole when it comes to disclosure and fulfillment IMO. Seems like they are China-based?? I do like the design of the Doomsday shield, the board would be very useful for precision time-keeping displays. I also like their “Mama’s Extremely Accurate Real Time Clock” which uses the DS3231. Prices are good, but we still don’t have fulfillment shipping source and cost information. Ian, please contact Tully and help him to sort this out.

    Sorry I did not make that more clear. I have all the stuff made in Shenzhen China. For US customers who want things quickly I tried to keep as much inventory as possible in the United States I have not figured out any reasonable way to show how much of each product is in America and China, with the shopping cart software that I use “PrestaShop”. I suppose I can try to add some of this information in the description. I have placed a number of doomsday clocks on eBay, these ones will ship from New Mexico, USA.
