Altium CircuitMaker was used to design the schematic & PCB. The files are open source and available here. The design uses four flashing 3mm orange LEDs on the points of the compass and a single 0603 SMT blue LED in the center. They’re all powered by a single 3V CR1225 coin cell battery.
In a project this week, I had a need to solder a resistor directly to an LED. Due to the human limit of only having two arms, this turns out to be a little more difficult than it should be. Normally, I’d use my “extra hands” tool for this type of task but I had a lot of them to make and I needed a more efficient process. Here’s what I came up with…

My son’s 6th birthday party recently became one of those moments.
I recently put out a request to a fellow Gadgeteer enthusiast, Eric Hall (aka ransomhall), to help me out with a simple module that I needed to help make some temporary breadboard modules I have been testing a little more permanent. Eric responded with a very professionally designed module that I anticipate using to make several projects I have in the works look much more polished and take a lot less space on my desk.
