Kill Time Making Flappy Bird, Not Playing It

With all the Flappy Bird clones floating around in the ether after the game’s unexpected success, there are some that are better than others. And by better, we mean, hacked together from misc hardware. If you’ve got an Arduino on hand, then you’re half way to making your own:

The “Minimalist” Version

[aron.bordin] created his own Flappy Bird game with a short list of parts some of us likely have lying around on our bench. An Arduino loaded with the appropriate code is wired to a 16×16 LED matrix, which apparently displays the minimal amount of visual information you’d need to play the game. The only other parts required are a single pushbutton and resistor tethered on a breadboard to control your flapping. With the wire hookup laid out by convenient diagrams and the libraries required for the code all found on the same page, this is easily something one could bang out in an afternoon. If afterwards you still find yourself with more time to kill than you can stand to play Flappy Birds, there is always the option of fashioning a humorously-sized cell phone case to squeeze it all into… which we’d like to see.

The “Fancy” Version

If you want more resolution than solid colored LEDs, or you just have a fondness for the terrifying bird abstraction the game is known for, you can switch out the 16×16 matrix for a Nokia LCD screen. [Huy’s] rendition of this build over on will deliver a “more detailed” graphic for the game, and is still roughly just as easy to assemble. Similarly, an Ardunio is loaded with the smarts required to generate the game, along with a single pushbutton tacked on for control. The code and the daunting (/sarcasm) two steps needed to wire the Arduino to the screen can be found on his project’s page.

If you must kill boredom playing Flappy Bird, there is no excuse not to do so on something you made yourself.

Using PWM to control the light intensity of a LED

INTRODUCTIONPulse-width modulation (PWM), or pulse-duration modulation (PDM), is a technique used to encode a message into a pulsing signal. It is a type of modulation. Although this modulation technique can be used to encode information for transmission, its main use is to allow the control of the ...

Guitar Hero: Guitar w/ Strings (MaKey MaKey)

Utilizing the MakeyMakey program, we have constructed a guitar out of a scrap wood plank, ten screws, five stripped copper wires, and of course the MakeyMakey creation kit. The guitar acts as an alternate controller to the traditional Guitar Hero guitar, which was played with five different-colored ...

Digitally Controlled Circuit Bending

Circuit bending doesn’t get a lot of respect around some parts of the Internet we frequent, but there is certainly an artistry to it. Case in point is the most incredible circuit bending we’ve ever seen. Yes, it’s soldering wires to seemingly random points on a PCB, but these bend points are digitally controlled, allowing a drum machine to transform between bent crunchiness and a classic 1980s drum machine with just a few presses of a touch screen controller.

All circuit bending must begin with an interesting piece of equipment and for this project, [Charles], the creator of this masterpiece of circuit bending, is using a Roland TR-626, a slightly more modern version of the TR-606, the percussive counterpart of the infamous TB-303. The circuit is bent in the classical fashion – tying signals on the PCB to ground, VCC, or other signals on the board. [Charles] then out does everyone else by connecting these wires to 384 analog switches controlled by an Arduino Mega. Also on the Arduino is a touch screen, and with a slick UI, this old drum machine can be bent digitally, no vast array of toggle switches required.

[Charles] has put up a few videos going over the construction, capabilities, and sound of this touch screen, circuit bent drum machine. It’s an amazing piece of work, and something that raises the bar for every circuit bending mod from this point on.

Thanks [oxygen_addiction] and [Kroaton] for sending this one in.

Grove Relay Basic using Intel Edison

Hello everybody.I am one of the lucky one who got Intel Edison from Instructables. When I got the the grove starter kit with Intel Edison, I understood what each element did except Groove smart Relay. I researched and came up with a small project to make you more familiar with Relay. Relay is kind o...
