I had a few of PCBs left over from the V3 MetaClockClock, and originally I planned to finish a build with them by the end of 2020. But as always: things took a bit longer than expected, so I finally finished it today on the first day of the year 2021.
The build uses the same hardware as in the previous V3, but instead of an ‘artistic’ canvas background I decided for a more natural and wood design:
It uses a walnut veneer on 3mm MDF and then laser-cut the holes and surrounded it with a pine wood frame.
It is smaller (71.5 x 28 x 5 cm) and includes a total of 24 dual shaft stepper motors with laser-cut PMMA hands (dual and extended version).
The PCBs with the RGB LEDs (WS2812B-SIDE) are put into 3D printed enclosures. The clocks snap into the enclosure, and the enclosure itself is attached with two screws to the front panel.
Compared to the V3 it is much easier and faster to build and assemble. For the wiring I used pre-configured cables I ordered from Aliexpress.
The back is closed and the whole thing can be hung on the wall, only requiring 5V and optionally the RS-485 interface.
Below how it looks:
Happy 2021 🙂
