Preproduction (Rev 3) units of the 6-inch tall seven-segment display are available for sale at the Reclaimer Labs store. All boards are fully assembled and tested. Each segment comes with a laser-cut cardboard waveguide and interconnect. These are early units, so not all the bugs have been worked out. As I update the design to the production design (Rev 4), I will post specifics. In the meantime, you can get started on your projects with these preview units. Enjoy.
