This is a new clock design which I’ve been working on for several days. It uses our multi-clock electronic circuit & hardware. The case is a completely new design from scratch. Can be printed by a rapid prototype machine. Comprised of 5 parts, front and rear body, 3 buttons and a rear lid for programmer slot. This product is the first one with this feature that enables firmware updates through this lid. Just open the lid, insert the programming socket and upload new firmware. No tools, no unscrewing necessary. Read on for downloading the necessary files. You can click this, this or this for our older clock designs.
