The meetup was a joint effort between the NashMicro user group and AllJoyn Nashville. NashMicro is a user group of Nashvillians interested in general microcontroller & electronics topics. Since AllJoyn is a topic of interest to NashMicronians (NashMicro members), it made sense to host this meeting with them.
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.
Hackaday.com recently ran an article called “Arduino vs. Phidgets – Dev Time Trials” which brought to attention a blog post by Ken (?) called “Hardware Protoyping Speed Test: Phidgets vs Arduino” which I thought was a rather fair set of tests for comparing development speed and costs for three simple projects. My objective is to run these same tests using the Gadgeteer rapid prototyping system and report my results. Of course, like any article of this sort there are always going to be some lively comments from the readers regarding the validity and bias of tests. I fully expect that this article will generate plenty of its own.
