My First Laser Cutting Order Ever

I’m delighted at how well the lunar clock is going! While waiting for stepper motors to arrive, I’ve been using Inkscape to create the laser-cutting pattern for the wheel that will contain images of the various phases of the moon.  After a few hours of stumbling around (I’d never used Inkscape), I was drawing circles, arcs, and lines with abandon.

The idea of the clock is that this wheel will be behind a picture of a sky, that has a moon-sized hole near the top.  The wheel will rotate to show the lunar image that most closely resembles the current phase of the moon.

WiFi and Steppers and Slots! Oh, My!

Lunar Clock project is starting to feel real!

After having no luck making the ESP8266 work with an Arduino Mega, I switched back to the wonderful Sparkfun CC3000 WiFi Shield. It is playing nice with the Mega now – with an interposed Sparkfun TransmogriShield to convert the Mega SPI pins to the Uno pins that many Shields expect. Update: I replaced both these retired boards in a later post.

I happened to have an old, inexpensive unipolar stepper motor lying around, so I’ve hooked it up and am able to precisely turn it using the Arduino Stepper library. I should probably write a Post about that.  The upshot is that after reading the comments in the Stepper library source that said the pin order the library uses, it was pretty easy.
