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.<\/p>\n\n\n\n

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.<\/p>\n\n\n\n

Did I mention perfboard was messy?<\/p>\n\n\n\n

The top does look a bit cleaner.<\/p>\n\n\n\n

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

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.<\/p>\n\n\n\n

I patched the cock-up and everything worked!<\/p>\n\n\n\n

Then I added some external buttons and all is complete!<\/p>\n\n\n\n

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 \ud83d\ude42<\/p>\n","protected":false},"excerpt":{"rendered":"
