Arduino Nano Every drives a DIY Hovercraft!
I love this tweet, showing someone riding a hovercraft inside their own house…
Check out how Gadget Master Jacob Krizan used an Arduino Nano to control his DIY rideable electric device, with the goal “to improve the drivability, ease of use and safety of the craft”.
To be precise, he used an Arduino Nano Every, which costs around $10 (I won’t dare venture into the mechanics of the hovercraft itself, note). This is an evolution of the traditional Nano board, but features a more powerful processor, the ATMega4809. According to Arduino, it will allow you to make larger programs than with the Arduino Uno (it has 50% more program memory), and with a lot more variables (the RAM is 200% bigger).
A typical Arduino Uno prototyping scenario.
First of all, we see the Arduino Uno in the lower-left-hand corner of the image. A little to the right, we see a stick of eight WS2812B tricolor LEDs (commonly known as “NeoPixels” because that’s what the folks at Adafruit call them). In addition to red, green, and blue sub-LEDs, these little scamps also contain three 8-bit pulse-width modulators (PWMs), thereby allowing each NeoPixel to display 2^8 2^8 2^8 = 2^24 = 16,777,216 different colors. Also, these little rascals are daisy-chained together, which means we can drive the whole stick using a single digital output from the Arduino Uno.
This tech guru living in Durham, New Hampshire, has built a robot armed with a laser pointer to keep his cat entertained. Joseph Lapierre films as his DIY device moves the laser across the room with his feline in hot pursuit. The filmer said: "Using an Arduino Uno, two micro servos, and a laser, I created a robotic laser for my cat! "It has 3 modes, random, dash, and square. It was my first time using Arduino, anyone can make cool projects like this!" This footage was filmed on March 9.
