Something you may have seen previewed on my Youtube page was this “automated cigar box” that I haven’t quite figured out a good name for. Several interesting names, such as the “CopBox,” “RedVSBlue,” and “Red Chomper” have been suggested, but if you feel you have a better name, be sure to let me know in the comments.
Even though I say “red” and “blue” at first to cause it to open, what really drives this device is the noise level coming into a microphone mounted internally. This mic input then gives a signal to an Arduino Uno microcontroller, that tells the servo via a PWM output to lift the lid.
Once open, a really cool device known as a LED programmable strip is then commanded to either “sweep” a red or blue signal depending on the height. I’ve got some further plans for this strip that don’t include just flashing blue or red across it, so be sure to check back to see what happens. Oddly, I didn’t ever really mean for this to look like a police cruiser, so I’m glad that someone pointed that out. If you ever get pulled over by a flashing cigar box, just ignore it.
Like many of my more involved projects, I’m going to go into the details of the build in separate posts, but I thought I would introduce it here. Hopefully I’ll have video of some more interesting LED strip movement, but at the very least I’ll explain how it was programmed/wired and the mechanical build as well. In the mean time, why not check out the original “Boxie the Creepster.” It does something similar, but accomplishes it in a very different way.
