During the summer, gardens abound — so many people are keeping an eye out for their sun-ripened, home-grown tomatoes or for that lovely hydrangea that’s just the right shade of blue. But summers are also a very hectic time. So how do you maintain that garden and make sure it receives the care it needs? One of the projects created for the Digilent Design Contest 2015 is a smart irrigation system intended to work with an Android device to see to it your garden gets the moisture it craves.
We’ve been doing a lot with 3D printing around the office lately. Kaitlyn has been using Tinkercad primarily for making robot parts for the Digilent MRK and SRK, but she obviously didn’t start with a project on that level. To begin, she decided to make something simpler to get used to Tinkercad’s basic functionality. A cookie cutter seemed like a good place to start, so Turbo (our MakerSpace mascot) lent his likeness to it.
Did you ever play the game Battleship as a child? I remember finding it incredibly fun. This weekend, I found a new take on it! The version on Instructables uses a breadboard, wires, and other electrical components. It’s designed to teach children the basics of breadboarding — and to have fun, of course!
So, who’s excited about ECEDHA? We here at Digilent wanted something big and flashy to amaze everyone, so we put this together. We carry weatherproof strips of the WS2812 addressable LEDs in 1m lengths with 30 LEDs on each strip, so what better way to grab your attention than to build a display with 30 strips!
An impossible object is a two-dimensional figure that, at first glance, looks like a real 3D object. However, further inspection will lead to the conclusion that the object can’t actually exist in 3D. One famous example of this is the Penrose triangle. The concept was used in M.C. Escher’s famous Waterfall, and you might also recognize it as Digilent’s logo.
A friend of mine came into town for Christmas and I wanted to do some sort of photography project with him. A few months ago, there were some pictures floating around the internet from Stephen Orlando, who took LEDs and attached them to a kayak paddle and kayaked around a lake, and through rapids. I wanted to do something similar. The first night wasn’t very organized. We went into the woods with just the LED strip, the chipKIT board (the uC32), and a battery.
Without its two chocolate shortbread cookies, an Oreo is just a dollop of icing. A Christmas tree without the tree is just a pile of ornaments and lights, a sandwich without bread is just a salad, and a robot without a chassis is just a tangle of wires and electronics. That’s why my For Cheap Robots series had three tutorials on how to make a cheap chassis for your robot, long before I even touched a soldering iron. But what if the chassis and electronic components were one and the same?
At one point or another, we have all played the “Simon Says” game. In this game, one person, Simon (or Susan, Chad, or whoever happens to be the leader), will say “Simon says” and tell all of the other players to do something, such as raise their left hand. The catch in this game is that if the leader tells the other players to do something without saying the words “Simon says” and the other players do it anyway, they’re out. I personally really enjoy playing Simon Says, but I thought it could even be more fun if you could play Simon Says with a bunch of LEDs…
