Forget all of this video game nonsense: pinball is the real king of gaming. After all, it involves large pieces of metal flying around at high speed. [retronics] agrees: he has resurrected an old Briarwood Aspen pinball table using an Arduino.
When he bought the table, he found that the electronics had been fried: many of the discrete components on the board had been burnt out. So, rather than replace the individual parts, he gutted the table and replaced the logic board with an Arduino Mega that drives the flippers, display and chimes that make pinball the delightful experience it is. Fortunately, this home pinball table is well documented, so he was able to figure out how to rewire the remaining parts fairly easily, and how to recreate the scoring system in software.
His total cost for the refurb was about $300 and the junker was just $50 to start with. Now for $350 you can probably find a working pinball table. But that’s not really the point here: he did it for the experience of working with electromechanical components like flippers and tilt switches. We would expect nothing less from the dude who previously built an Android oscilloscope from spare parts.

Last year, among other projects, they worked on an unconventional communication campaign to narrate the re-opening of the well-known Turin’s Egyptian Museum, displaying a collection of over 30,000 ancient pieces.
The campaign’s goal was to hold people’s attention over six months before the official opening of the Museum and be able to speak to a broad national and international audience.
TODO created an open air installation composed by an almost-4-meter-tall hourglass (with a hidden mechanism running on Arduino) that had to work day and night, for six months and over the winter. According to Wikipedia, this hourglass could be the 4th biggest of its kind in the world!
The main challenge was that they had to make sure that the very last grain inside the hourglass would fall on the day of the Museum’s inauguration.
The installation was created thanks to many collaborators among which Gabriele Gambotto who developed the electronic part based on the Arduino Yún on which they added a custom shield ( See pic below), connected to various sensors and a precision scale. The sand-like material passed through a valve and a long screw conveyor controlled by a mot
Take a look at the video of the ‘Hourglass Countdown’ and to see it in action:
In an indoor area of the museum an interactive display case was the other face of the campaign revealed to the audience:
A series of replicas of ancient Egyptian finds were covered in sand, and users could interact with the system by choosing the spot they wished to unveil, blowing into a microphone, and having their breath converted by a small robot arm, which placed itself in the exact spot, blew away the sand and revealed part of the find.
The experience came to life in two different contexts. Locally, a roadshow with several stops made the display case accessible all around the city. Online, through the campaign’s website, you could blow away the sand from anywhere in the world, seeing the live streaming video of the robot moving and unveiling the find.
Check the video to see the amazing expression of people discovering ancient objects below the sand:

How long can you keep an Arduino circuit running on three AA batteries? With careful design, [educ8s] built a temperature sensor that lasts well over a year on a single charge of three 2250 mAH rechargeable cells (or, at least, should last that long).
Like most long-life designs, this temperature sensor spends most of its time sleeping. The design uses a DS18B20 temperature sensor and a Nokia 5110 LCD display. It also uses a photoresistor to shut off the LCD display in the dark for further power savings.
During sleep, the device only draws 260 microamps with the display on and 70 microamps with the display off. Every two minutes, the processor wakes up and reads the temperature, drawing about 12 milliamps for a very short time.
Along with the code, [educ8s] has a spreadsheet that computes the battery life based on the different measured parameters and the battery vendor’s claimed self discharge rate.
Of course, with a bigger battery pack, you could get even more service from a charge. If you need a refresher on battery selection, we covered that not long ago. Or you can check out a ridiculously complete battery comparison site if you want to improve your battery selection.

It is almost impossible these days to find a PC with old ISA card slots. Full size PCI card slots are in danger of going the same way. Many PCs today feature PCI Express connectors. PCI Express offers a lot of advantages including a small size, lower pin count, and a point-to-point serial bus topology that allows multiple simultaneous transfers between different pairs of end points. You’ll find PC Express connectors in things other than PCs too, including a lot of larger embedded systems.
If you ever wanted to prototype something on PCI Express, you’d usually turn to an FPGA. However, [moonpunchorg] posted a workable design for an Arduino on a mini PCI Express board. (As [imroy264] points out in the comments, the board is using the USB port present on the PCI-E connector.) The design files use KiCAD so it should be fairly easy to replicate or change. Naturally, there are pins on the edges to access I/O ports and power. You do need to use ISP to program the Arduino bootloader on the chip.
The board appears to a host computer as a SparkFun as a Pro Micro 3.3V board, and from there you could easily add function to a computer with a PCI Express slot using nothing more than the Arduino IDE. The board is known to work with the VIA VAB-600 Springboard and VIA VAB-820 boards, although it is likely to work with other PCI Express hosts, too.

If you feel like experimenting with connected objects, a good idea could be to start from a funny project explained step-by-step in a tutorial. In the video below you can follow the instructions given by Dana, Documentation Hero at relayr, using an Arduino Yún, a gas sensor and relayr cloud to make a little Batman-shaped toy dance according to data:
I used a moisture sensor as an input and a servo motor as an output that I can control through a demo web application made using the browser-sdk.
The code in this repository will enable you to use your Arduino to build a prototype of a device and connect it to the relayr platform, much like the one created with the Particle.io Photon. It contains instructions and a demo app which will make your first few steps in the relayr-Arduino prototyping realm easy and fun!
Every year the students of the Copenhagen Institute of Interaction Design (CIID) attend the Physical Computing class as part of their curriculum.
Having a small delegation of the Arduino team teaching this class has become quite a ritual. This past March Ubi De Feo, Alice Pintus, and Lorenzo Romagnoli runned the two-weeks-long intensive class.
Teaching at CIID is great experience, since you are surrounded by incredibly motivated and curious students, that are doing everything possible to design amazing projects and prototypes.
The topic of this year was prototyping interactive installations for a Science Center that would explain in a playful and engaging way how a technology works. For most of the students this was the first experience with physical computing, but even in such short time they were able to build eight different prototypes. The projects explain in an interactive way the science behind computer viruses, allergies, video compression, machine learning, laser printing, digital music synthesis, binary numbers and neuroprosthetic.
In Explaining laser printing Victoria Hammel, Chelsey Wickmark, Ciaràn Duffy, Feild Craddock demonstrate how the laser printer works. By using 16 servomotors connected to an Arduino UNO to move a matrix of magnets they were able to attract iron filings and draw letters on paper.
In Troyan 77 Karan Chaitanya Mudgal, Liliana Lambriev, Gunes Kantaroglu, Dhruv Saxena visualize the effects of a Trojan Virus harming your computer. Connecting Processing to Arduino they were able to create an overlay projection on top of the maze representative of the effect of the viruses on a computer.
Sound Blocks by John Ferreira, Alejandra Molina and Andreas Refsgaard is an musical instrument that explain how to compose sounds combining multiple soundwaves. The prototype was built using Arduino as a midi controller for Ableton.
