I love creating hobby projects powered by simple 8-bit microcontrollers. In fact, most of my creations use an Arduino Uno or Arduino Nano, both of which have only 32KiB of flash memory (for program code), 2KiB of RAM for data and variables, and run at only 16MHz.
Of course, when I say “only” in any of these contexts, these would have been mind-boggling numbers back in the mid-1970s when I first started playing with 8-bit machines, but we digress…
I just received an email from someone we’ll call John (because that’s his name). John was kind enough to point me to this video about a guy who goes by the moniker “Uncle Stem,” who obviously has too much time on his hands because he’s built a giant Arduino.
Most of this is just 3D printed parts that do little of use but look awesome (much like me). But then you have parts that do need to do things, like the light-emitting diodes (LEDs), the reset button, and the header pins, so you can plug wires in and use it to communicate to the outside world.
The whole thing is actually powered by a real Arduino Nano, and the way Uncle Stem has implemented everything is a master class in “how to do things right.”
All I can say is that one of these bodacious beauties would look absolutely amazing mounted on the wall here in my office.
