Doggy Buttons!
Inspiration
This project was born from two desires. One, see if our dog could be taught to use buttons without spending piles of money. Two, to make use of an ancient Raspberry Pi.
Lots of people have done a project like this, and it isn’t necessary to use a Raspberry Pi. That just happened to be the only unused piece of electronics I had on hand with audio output. But, I will say that I definitely recommend this approach for a couple reasons. Firstly, it’s very easy to get running in Python with Adafruit’s Blinka library. Second, it leaves lots of room for growth (both in number of buttons and features like button presses sending digital messages).
Be sure to read all the way to the bottom for a cute puppy photo! -
Look Ma, No Microcontroller! (Night Light Edition)
Inspiration
This is a piece of "found art"; a multi-colored circuit board hiding inside some old discarded electronics. It just needed a backlight and a frame to highlight its beauty. From the beginning, I knew this would become a nightlight and held onto the board until I had acquired the perfect combination of discarded LEDs and a few other components needed to make it shine.

Stuff My Dog Said (via AdafruitIO)
Inspiration
This project is an extension of the original doggy buttons project where I'll be showing how to make a public dashboard that publishes everything my dog says. This project is just one example of how to extend the features of my doggy buttons and perhaps one of the silliest IOT devices ever made. If you want to know about the buttons themselves, see the original project writeup.
With a project like this, it's also important to think about privacy. I don't want my dog making it possible to tell when we're away from home, so I'll also show how to add a delay so that activity is only published once it's sufficiently stale. -
Look Ma, No Microcontroller! (RGB LED Edition)
Inspiration
Making beautiful patterns with RGB LEDs is a popular electronics project, but the possibility of generating these patterns with only a piece of flash memory, six D type flipflops, and a 555 timer was too tempting a project to pass up. I'd been puzzling over what to make from the 8 feet of dumb RGP LEDs I'd picked up from Goodwill and when someone shared this link explaining how to make a finite state machine from simple electronic components, something clicked and I couldn't stop thinking about how to combine the two "dumb" systems into something beautiful.
