Clock Project

When I was recovering from a hernia operation I designed a clock around an Arduino, real time clock board and temperature/humidity sensor. This was built onto breadboard and was as flaky as hell due to poor connections.

Recently I decided to build the project using perfboard, which is messy and caused 2 magic smoke release incidents, and bought a case to keep it all looking tidy.

Did I mention perfboard was messy?

The top does look a bit cleaner.

I decided to try my hand at PCB design so I got to grips with that at EasyEDA and sent of the design to PCBWay for production. A few weeks later I had 11 prototype PCBs.


The PCB wasn’t perfect (my fault). The silkscreen was slightly wrong and I found out after build that the SDA and SCL connections were reversed.

I patched the cock-up and everything worked!

Then I added some external buttons and all is complete!

I have corrected the PCB design and gave it rounded corners, sent off the order and now just await delivery. All in all I’m very pleased with this 🙂

    Just below the picture of the PCB upper surface.
    You patched up the what?

    Filth. Disgusting filth

    Nice. I’ve never had the courage to send off a PCB design. Veroboard all the way for me so far.
