Clock PCB mounting
My plan to mount the printed circuit board onto the back of the clock was to use some screwed PCB mounts which were screwed onto double threaded woodscrews fixed into the back of the clock. I chopped the end of

Shortening the screws
So that the Topsy Turvy Clock has a good finish I decided to trim some of the brass screws so that they would be flush with the plates rather than sticking up proud. To facilitate this process I made a

Spacers
A simple but important part for the clock was the spaces that connect the two clock frames together. These were a simple machining job, brass rod was faced off and drilled with a 2.3mm drill. It was then parted off

Small screwed bush
The next component to machine was one I like to call the “Top Hat”. It fulfuls two purposes, it holds the clock mechanism to the face of the clock and it acts as a bush to support the spindles that

More clock shafts
After my previous success drilling a tiny but deep hole through some brass rod, I got thinking about how to machine the outsides. Referring back to my diagram the idea was to take a 4mm rod and machine most of

Shorted pins workaround
In my previous Topsy Turvy clock post I mentioned that two of the output pins of my Arduino Micro were shorted together. I desoldered the pins and inspected the board using a magnifying glass. I even tried cutting at the

Testing Testing
Over the last couple of weeks I’ve made some progress wiring the clock hostboard and building the plate that supports the motors. I thought I’d test these together. Before I powered on the circuit or plugged in the Arduino Micro

Clock motor plates and host circuit board
Some progress on the Topsy Turvy Clock over the weekend but still lots to do. The electronics have been wired up on their host board. The board was a “tripad” board which is like stripboard but the pads are split
