Clock Part 3

I finally finished the outer case of my clock. Only 19 layers of 3mm acrylic stacked on top of each other.

Laser cutting the rear panel and finger slot

Rear panel with finger slot and barrel jack holder

Barrel Jack inside the finger slot

I built a finger slot into the back of the clock so it’s easier to carry, but also to house the barrel jack for mounting the clock flush to the wall, allowong me to hide the power cord in the wall (oneday)

This is the pile of acrylic I had to cut out of the inside of the clock.

That pile on the left was cut out to make the cavity in the case.

A bit more progress on my clock. I installed the dirty pink gel filter to increase the contrast ratio of the 7 segment displays, and started cutting the final case out of red 101 acrylic. Lots of laminations.

I finally wired up the big LEDs and made an acrylic mounting board for all the parts. I laser cut holes in the board and tapped them with an M3 tap. That allowed me to mount the circuit boards directly to the mounting board. I used Dupont connectors to wire everything up which gives a very neat finish I think.
