With the electronics and code in place, there’s not much left to do and say. Or so i thought.. It turns out that completely covering black lines on a white background with white spray paint takes a lot of layers. It ended up taking me months before there had been enough dry days where I was home, and day the paint could dry before the face plate was ready for the facility.
I decided to use water decals, to add the new graphic to the face. I have some experience with it, and a lot of the slides/papers at hand. What I didn’t think about, was that the clock face is concave, and rather difficult to slide thin sheets around on. But with some patience and a brush it worked all right!
There is a time lapse of it here:
I thought the strip to the right would help. I’m still not sure. But it was easy to remove by a light cut with a sharp knife, when the decal had dried. Then it got a couple of coats of varnish to blend the small edge of the decal in.
In the end it looked like this:
It could have been sharper. But with the acrylic in front and up on the fridge, it works quite good.
Because the only electronics are a MCU devboard and the driver board for the motor, I simply soldered the driver board to the devboard, and deadbugged the capacitor to the power pins on the devboard.

While it certainly was a slow process the last bit, I’m quite satisfied with the build. It now remind me to take it easy every morning when I grind my coffee beans.
