I decided to try to make the frames myself. The first step was to make some jigs for holding the wood to make it easier to manufacture the frames. I got a sheet of MDF, made the jigs and cut the rest of the wood down to size in preparation of making the frames. And my new PCBs came in, along with more parts to build more clocks!
Several changes to the schematic and PCB layout had to be made.
- Corrected which pin drives the buzzer – The issue with RA4 inadvertently being connected to the LED matrix has been corrected in the new layout of the PCB.
- Moved the Alarm and PM LEDs – When either or both of these LEDs are lit, it makes it more difficult to determine the time, especially in low lighting conditions. Perhaps moving these LEDs closer to the center of the board will help with that. Other options in software may be explored,for example, making these LEDs dimmer.

After a bit of a slow start, I have finished making the adjustments to the frame. It will be 1/8″ (3mm)thinner, which may not seem like much, but it brings the tops of the larger LEDs flush with the face of the frame. The rounded edges of the frame will have a larger radius, to give it a more sleek and rounded look. The back side will have a couple of modification as well that will aid in its manufacture. I needed to start with the frame as the changes will have an effect on the PC Board’s size and location of mounting holes.
