Just rediscovered Upverter, have started learning the ropes and creating my schematic. The goal is to layout a pcb for the "permanent" version of this thing. I have some protoboards that I could use, but as a large motivation behind this endeavour is to learn new stuff I would prefer to get some experience with producing a pcb layout.

Here's a schematic of the current setup. Had to do a little connection shuffling to free up digital pin 2 for the external interrupt, using the tact switch to change modes (poem, clock, compass). Next step is to gather the useful parts of my various test sketches into a functioning unit and tweak the poetry portion.

The two modules arrived and I assembled the DS1307 RTC kit. The basic code for generating the "poems" is working (still on the Pro Mini). I attempted to compile it for the Teensy-LC but got an error related to the library I'm using for the seven segment display and a warning related to using an array of strings. I'm debating whether to figure these issues out now before proceeding with the Teensy-LC or if I should continue with the Pro Mini and then adapt for the LC later. Any ideas of alternative ways to handle the seven segment display on the Teensy?

Just ordered the RTC and magnetometer modules. Decided on the LSM303 triple-axis accelerometer and magnetometer from Adafruit as the feature/price factor seemed like the best value. Continuing to sketch ideas about how to use the seven segment display in various ways and reconfigured the circuit-thus-far on the breadboard to make room for the two modules.
