Here is how we can help (and this is the exact reason why we described Wise Clock 3 as "highly hackable"):
1. If you already have Wise Clock 3, buy just the "Night and Day add-on kit", which includes
- the world map printed on thick velum paper;
- one thin (1.5mm) transparent acrylic laser-cut plate;
2. If you don't have Wise Clock 3 already, you can order the "Night and day add-on kit" alongside either the board kit or the complete kit. In this case, we will upload the sketch onto the processor for you.
