~ Project Pages and Instructions ~
NOTE: It is not absolutely necessary to build the enclosure before programming the MCU. You can proceed with pages 5 and 6 above first if you wish, but be aware that if your boards come into contact with any metal objects while doing so, that you might damage the circuitry or board components. For that reason, it is advisable to build the enclosure and mount your boards prior to powering up or programming your MCU.
Your enclosure can be plastic, wood, fiberglass, heavy cardboard, gutta-percha, even woven palm fronds, ANYTHING BUT METAL. Metal enclosures will block the Bluetooth signal and your DRO system WILL NOT WORK. There are many inexpensive yet very suitable plastic enclosures available on the market and we highly recommend that you purchase one of them with interior dimensions suitable for the board combination that you have built.
Your enclosure must also be large enough to contain all of the components as assembled, plus must allow room for as many USB ports as you plan to use.
Due to the huge number of possibilities for enclosure/component layout, enclosure size, etc., we will not cover the details of constructing your enclosure or mounting your components in it. There are plenty of tutorials available on the Internet that can guide you through those steps. You will need to create openings in your enclosure for the power cord, the MCU programming port, as well as the ports for each scale connection. Simply search the web for "how to mount electronics in an enclosure".
