I am just getting the components together for version 0.2. I ordered a nice ST756R LCD displays that is much bigger (47x30mm) than the HX1230 and also has a higher resolution. I also want to reduce the overall thickness in the next iteration. For that I got a thinner battery (4mm) and consider using thin 2mm acrylic for the front-plate. Maybe I‘ll try to color fill the engraved plastic - yellow on black would look rather nice I think.
