In Progress… I never got to build my own model rockets as a kid. It’s surprising really, since I spent a lot of time launching far less flight-worthy objects through the air with ridiculous feats of garage chemistry. Remember this was before the days of YouTube (*sigh*, amateurs). So when I ordered a pair of…
Most premade bluetooth modules for Arduino, particularly in proper shield form, can be pretty expensive for just kicking around on the workbench. This turned out to be a pretty easy alternative that’s also relatively inexpensive.

So with an old mason jar, four LED’s and resistors, and a spare atmega chip sitting on the bench, I decide to just slap one together.
I had an old USB GPS puck sitting around and wondered if I could make it play nice with the Arduino. Of course, there are easier modules (including this one in serial) that can be found elsewhere for a few dollars more. But assuming you have this one, it can be done.
